Older homes often come with their own set of HVAC challenges—limited ductwork, uneven temperatures, and poor energy efficiency. If you live in a historic or vintage property, you may be wondering whether a ductless mini-split system is a smart solution. The answer is yes—these systems are an excellent option for older homes without the need for invasive remodeling.

At ACE Appliance Heating and Cooling, we frequently install ductless mini-splits in homes that weren’t built with central air in mind. Mini-splits offer a flexible, energy-efficient way to heat and cool individual rooms without tearing into walls or ceilings to install ducts. That means no major construction, no damage to architectural details, and no hassle.

Whether you’re looking to upgrade a single room, finish a garage or attic, or provide whole-home comfort in a property with limited ductwork, ductless systems deliver customizable comfort. They’re a modern solution for preserving the charm of older homes without sacrificing comfort or performance.

Ductless systems provide reliable temperature control and energy efficiency, all while protecting the structure and aesthetics of older properties.

These systems can be installed in specific rooms or across your entire home, depending on your needs. Since they don’t rely on ducts, they eliminate the energy losses commonly associated with forced-air systems.

Many older homes weren’t built with ductwork in place, making traditional HVAC systems difficult—or extremely expensive—to install. Mini-split systems solve this issue by operating with a simple indoor unit connected to a compact outdoor condenser via a small refrigerant line.

This setup allows for easy installation with minimal disruption to walls, plaster, or decorative trim. Since each indoor unit operates independently, homeowners can heat or cool rooms as needed—perfect for homes with uneven insulation or inconsistent room usage.

If you have an older home with high ceilings, thick walls, or drafty rooms, mini-splits provide a cost-effective way to modernize your comfort without compromising the integrity of your space.

At Ace Appliance Heating and Cooling, we begin with a consultation to assess your home’s layout, insulation levels, and comfort goals. Based on your needs, we’ll recommend the number and placement of indoor units and ensure the outdoor condenser is properly located.

Our expert technicians install your system with minimal disruption—no bulky ductwork, no extensive wall cutting, and no need to move furniture. Most installations can be completed in a day or two, depending on how many zones are being added.

After installation, we’ll show you how to use your remote or smart thermostat, set up energy-saving schedules, and maintain the system for long-term efficiency.

If you’re tired of battling hot or cold rooms, noisy window units, or expensive ductwork quotes, it’s time to consider a ductless mini-split system. Whether it’s a full upgrade or a targeted solution for one space, we’ve got you covered.

If your thermostat screen is blank or won’t respond, your HVAC system can’t communicate, and your heating or cooling won’t turn on. This can be frustrating, especially during extreme temperatures, but the issue is usually caused by something easily fixable—such as dead batteries, a tripped circuit breaker, or a wiring issue.

At ACE Appliance Heating and Cooling, we often hear from homeowners worried their entire HVAC system is broken when the root cause is a power-related issue at the thermostat. The thermostat acts as your system’s brain, and when it goes dark, your furnace or AC won’t receive the signal to operate—even if the rest of the system is in perfect working order.

Some thermostats have battery backups, while others rely solely on power from the HVAC system itself. Knowing what to check first can save time, prevent costly repairs, and get your comfort restored quickly. Let’s walk through what causes this problem and how to troubleshoot it safely.

Several common issues can cause a thermostat screen to go blank. Most are simple to resolve with a quick inspection.

Check the most obvious issues first: try replacing the batteries (if your model uses them), and inspect your breaker panel for tripped switches. If that doesn’t restore power, there may be an issue with your system’s control board or wiring.

You can perform a few safe troubleshooting steps before calling for HVAC service. Start by checking your thermostat’s power source. If it’s battery-operated, swap in fresh batteries. If it’s wired, head to your electrical panel to see if a breaker has tripped.

If the screen remains blank, check for a fuse near your indoor HVAC unit or furnace. In some systems, a blown low-voltage fuse can interrupt power to the thermostat. Make sure the thermostat isn’t mounted near a heat source or in direct sunlight, which can also affect performance.

If these steps don’t solve the issue, there may be a deeper problem with the control board, transformer, or thermostat itself—requiring professional attention.

When you call us for a blank or unresponsive thermostat, our technicians begin by testing the power flow to the thermostat and checking for system-wide issues. We’ll inspect the furnace control board, test low-voltage wiring, and verify that the thermostat is properly connected and receiving voltage.

If the thermostat is faulty, we can install a compatible replacement—whether it’s a basic model or a programmable smart thermostat. We’ll also make sure everything is wired correctly and communicating with your HVAC system as intended.

In some cases, a blank thermostat is a symptom of a bigger issue, like a failing transformer or a short circuit in the control wiring. Our team will get to the root of the problem and ensure your entire system is safe, reliable, and ready to heat or cool your home again.

If your thermostat screen is still blank after replacing batteries and checking breakers, don’t wait—call our team for fast, professional help. Continuing to reset or tamper with wiring may cause further damage if you’re unsure what to look for.

Ace Appliance Heating and Cooling provides prompt diagnostics and honest solutions to restore your comfort system and peace of mind.

A sudden power outage can disrupt your home’s HVAC system, leaving it unresponsive or behaving oddly even after electricity is restored. Whether your thermostat is blank or your AC or heat won’t turn back on, you may need to perform a system reset to get everything running smoothly again.

At ACE Appliance Heating and Cooling, we often hear from customers who assume something is broken after a storm or utility interruption—when in reality, a simple reset is all that’s needed. Power surges can confuse your HVAC’s internal controls or cause safety sensors to trip, temporarily shutting down system functions.

Fortunately, resetting most residential HVAC systems is straightforward and safe to do yourself. Knowing how to properly restart your unit after an outage can save you time, worry, and an unnecessary service call. If the reset doesn’t work, that’s when it’s time to call in our professionals to check for deeper issues.

Before beginning, always use caution and follow your manufacturer’s instructions. A basic reset usually involves these steps:

This process gives your system time to discharge residual energy and reboot fully. If your system still won’t turn on or blows warm air, a deeper electrical or component issue may be present.

During a power outage or surge, your HVAC system may shut off to protect itself from electrical damage. Internal controls like capacitors, sensors, and relays are vulnerable to voltage fluctuations. When power returns, the system may not automatically resume normal operation if these components were affected.

Thermostats, especially smart ones, can also lose their settings or fail to reconnect with the HVAC unit. In some cases, the system might appear to run but won’t produce heating or cooling until reset. This can be frustrating—but it’s often part of your system’s built-in safety protocol.

If your system doesn’t respond after a reset, Ace Appliance Heating and Cooling can quickly diagnose the issue and ensure it’s not a damaged component or electrical hazard.

If you’ve performed a reset and your system still doesn’t operate correctly, it’s time to investigate further. In some cases, a breaker may trip again due to a short circuit, or a capacitor may have failed during the outage. Repeated resets or system restarts may even do more harm than good if there’s an unresolved electrical issue.

Our trained HVAC technicians will inspect the unit’s power supply, wiring, thermostat, and safety sensors to locate the fault. We’ll test each component, check the voltage levels, and replace or repair anything that may have been damaged during the outage.

We also help homeowners prepare for future outages by recommending surge protectors, backup batteries for thermostats, and smart monitoring solutions. These simple additions can prevent downtime and extend the life of your system.

If your HVAC still isn’t working after a reset, or if the breaker trips repeatedly, don’t take chances with your system’s safety. What seems like a simple outage may have caused internal damage.

The experts at Ace Appliance Heating and Cooling provide fast diagnostics, safe repairs, and peace of mind. Call us for same-day service when power issues affect your comfort.

If one room in your home always feels too hot in summer or too cold in winter, you’re not imagining it—and you’re not alone. Uneven temperatures are one of the most common comfort complaints homeowners bring to ACE Appliance Heating and Cooling. This issue is often caused by airflow problems, insulation deficiencies, or ductwork imbalances that prevent consistent heating and cooling throughout your home.

Your HVAC system is designed to regulate the entire living space evenly. When one room stays outside the comfort range, something is disrupting the system’s balance. It could be as simple as a closed vent or as complex as poor system design. Either way, it’s a sign that your system isn’t performing as efficiently or effectively as it should.

Ignoring this problem may lead to increased energy bills, thermostat battles, and even unnecessary wear on your HVAC unit as it works harder to compensate. Solving the issue can improve your home’s comfort, boost energy efficiency, and extend the lifespan of your heating and cooling system.

There are several potential reasons why one room in your home may consistently feel hotter or colder than the rest, even when your HVAC system appears to be functioning properly. Uneven temperatures are a common issue and can be caused by a variety of factors. One of the most frequent culprits is poor insulation—if a room isn’t properly insulated, it may lose heat in the winter or allow excessive heat gain during the summer. Similarly, air leaks around windows, doors, or ductwork can allow conditioned air to escape or let outside air in, disrupting the room’s temperature balance.

These factors disrupt airflow and temperature balance throughout your home. Even newer HVAC systems can struggle with uneven distribution if the duct layout or insulation is subpar. Identifying the cause is the first step to fixing the comfort imbalance.

Uneven temperatures aren’t just annoying—they can negatively impact your home’s efficiency, indoor air quality, and HVAC system health. If one room is colder or hotter, occupants may over-adjust the thermostat, making the rest of the house uncomfortable and increasing energy use.

Over time, this puts added stress on your heating and cooling system, leading to higher utility bills and possible system breakdowns. It also signals airflow problems that may be affecting other rooms more subtly, even if you haven’t noticed yet.

At Ace Appliance Heating and Cooling, we specialize in identifying airflow problems and correcting system imbalances to restore consistent, whole-home comfort.

Our expert technicians begin by inspecting your duct system, checking airflow at registers, and evaluating insulation levels. In many cases, adjusting dampers, sealing ducts, or adding insulation can make a significant difference.

For homes with persistent hot or cold spots, we may recommend zoned HVAC systems or smart thermostats that allow independent temperature control in different parts of the house. We also evaluate window placement, sun exposure, and the role of ceiling fans in circulation.

No matter the cause, we provide clear answers and affordable solutions to help your entire home feel just right. At Ace Appliance Heating and Cooling, your comfort is our mission.

If you’ve dealt with that “one room” for months—or years—it’s time to stop guessing and get real answers. A simple system check can uncover duct or airflow problems that are easy to correct.

Our trained technicians offer fast, professional service and reliable fixes that improve whole-home comfort and reduce your energy costs. Let us help restore balance to your indoor environment.

If your HVAC unit keeps tripping the circuit breaker, it’s a clear sign that something isn’t functioning properly. While resetting the breaker once may be harmless, repeated tripping means your system is drawing more electricity than it should—or there’s an underlying electrical fault. Ignoring this issue can lead to permanent system damage or even pose a fire hazard.

At ACE Appliance Heating and Cooling, we know that an HVAC system is one of the most power-hungry appliances in your home. A tripped breaker is your electrical system’s way of protecting you from overheating wires or short circuits. So if your breaker trips again and again, it’s not something to brush off—it’s a call for immediate inspection.

There are many reasons this could happen: from dirty air filters restricting airflow to faulty components like motors or capacitors. It’s important to shut the system off and avoid repeated resets until a licensed HVAC technician can diagnose and safely fix the problem.

Your HVAC system may trip the circuit breaker for a variety of reasons, and identifying the root cause is essential to prevent recurring shutdowns and potential damage. In some cases, the issue could be something relatively simple, such as a clogged air filter that restricts airflow and causes the system to overheat. Other times, it may be due to dirty condenser coils, low refrigerant levels, or a malfunctioning thermostat—all of which force the unit to work harder than it should. On the more serious end, electrical problems like a short circuit, a failing compressor, or a damaged capacitor could be the culprit, posing potential safety risks if left unchecked. Because these problems can vary in severity, it’s important to address breaker trips promptly. A qualified technician can perform a detailed inspection to pinpoint the issue and recommend the right solution, ensuring your system operates safely and efficiently.

These issues make the system work harder than it should, causing it to pull excess amperage. The breaker trips to prevent damage or electrical fire. Identifying the cause early can help protect your HVAC system and home.

Resetting a tripped breaker again and again may seem like a quick fix, but it’s not. Doing so can overheat electrical wiring and damage critical HVAC components. Over time, it may lead to complete system failure, fire hazards, or damage to other appliances sharing the same circuit.

If the root cause is an overworked compressor or blower motor, continued use could burn them out completely—requiring expensive replacements. Worse, if the problem lies in the panel or wiring itself, it could lead to dangerous arcs or electrical shorts behind your walls.

At Ace Appliance Heating and Cooling, we always recommend turning off the system at the thermostat and calling us for a professional inspection right away.

Our licensed HVAC technicians will begin by inspecting your breaker panel, air handler, outdoor unit, and internal wiring. We’ll measure electrical loads, check all components, and test refrigerant levels to determine exactly what’s triggering the trip.

Once diagnosed, we’ll recommend the safest and most cost-effective fix—whether it’s replacing a capacitor, cleaning coils, tightening a connection, or rerouting wiring to reduce load stress. In some cases, we may work alongside a licensed electrician if panel upgrades are needed.

We never cut corners when it comes to electrical safety. With Ace Appliance Heating and Cooling, you’ll get transparent service, detailed explanations, and repairs that prioritize your system’s performance and your home’s protection.

If your HVAC trips the circuit breaker more than once, don’t risk further damage by flipping it back on. That breaker is telling you something’s wrong—and it’s protecting your home from worse problems.

Our expert technicians respond quickly, diagnose accurately, and fix the issue safely. Call Ace Appliance Heating and Cooling at the first sign of electrical trouble with your HVAC system.

If you’ve turned on your air conditioner and noticed a musty or mildew-like smell, you’re not alone. This unpleasant odor is a common complaint from homeowners and usually indicates moisture buildup or mold growth within your HVAC system. While it may seem like a minor annoyance, a musty-smelling AC should not be ignored.

At ACE Appliance Heating and Cooling, we understand how indoor air quality impacts your health and comfort. That musty smell is often a warning sign that your AC system needs maintenance—especially if you notice it every time the system starts. Mold, bacteria, or dirty components are frequently to blame, and addressing them early can help prevent more serious issues down the line.

Left unchecked, the source of the odor can spread spores throughout your home, aggravate allergies, and lead to respiratory discomfort. That’s why it’s important to pinpoint the cause and fix it fast. Fortunately, with the right maintenance and professional cleaning, your home can be fresh and odor-free again.

A musty or mildew smell coming from your air conditioning system is a common sign of excess moisture buildup combined with inadequate drainage or ventilation. This unpleasant odor is often caused by mold or mildew growth within the system, particularly in areas like the evaporator coils, condensate drain pan, or inside the air ducts. When moisture becomes trapped and isn’t properly drained away, it creates the ideal environment for microbial growth. Over time, these contaminants can circulate through your home, affecting indoor air quality and potentially triggering allergies or respiratory issues. If you notice persistent odors when your AC runs, it’s important to have the system inspected and cleaned to prevent further buildup and restore a fresh, clean airflow throughout your home.

Moisture and organic material inside your HVAC system create the perfect environment for mold to grow. When your AC runs, it circulates this contaminated air throughout your home. Catching these problems early helps preserve your indoor air quality and avoid more expensive repairs.

That “wet sock” smell isn’t just annoying—it can also be hazardous. Mold spores and bacterial growth inside your AC system can spread allergens, irritants, and even pathogens through your home’s air. People with asthma, allergies, or weakened immune systems are particularly at risk.

Even if you don’t have respiratory issues, poor air quality can lead to headaches, fatigue, and general discomfort. Additionally, your HVAC system has to work harder to push air through clogged filters or mold-covered components, leading to reduced efficiency and higher energy bills.

If you notice a persistent odor, it’s important to schedule an inspection before the problem spreads or worsens. At Ace Appliance Heating and Cooling, we offer fast, effective solutions to eliminate musty smells at the source.

At Ace Appliance Heating and Cooling, our technicians begin by inspecting your entire HVAC system to locate the moisture buildup or mold source. We check the evaporator coil, air filter, drain pan, and ducts for signs of contamination or water accumulation.

We’ll clean or replace dirty components, unclog condensate lines, and treat the system with approved disinfectants if needed. In some cases, we may recommend duct cleaning or installing a UV light system to prevent mold from returning.

Our goal is not only to eliminate the smell but to improve your home’s air quality long-term. We use safe, proven methods to keep your AC running fresh and clean year-round.

If your AC smells musty every time it runs, or if the odor lingers even after replacing your filter, it’s time to call a professional. These odors don’t resolve on their own—and they usually get worse with time.

Trust our licensed HVAC team to find the root cause and restore clean, healthy air to your home. At Ace Appliance Heating and Cooling, we make your comfort and safety our top priority.

If your furnace is constantly cycling—turning on and off every few minutes—it’s more than just a nuisance. Known as “short cycling,” this issue can reduce energy efficiency, cause uneven heating, and lead to premature wear on components. It’s a warning sign that something isn’t working as it should, and it shouldn’t be ignored.

At ACE Appliance Heating and Cooling, we’ve helped homeowners across the region fix this common problem quickly and affordably. Whether it’s an airflow restriction, thermostat malfunction, or a deeper mechanical issue, short cycling puts stress on your furnace and compromises your comfort.

By understanding the most common causes, you can take steps to address the problem before it leads to costly breakdowns or complete system failure. Let’s explore what triggers short cycling, what to watch for, and how our HVAC experts can help.

Short cycling—when your AC system turns on and off more frequently than it should—is often the result of underlying, preventable issues. These may include something as simple as a clogged air filter, an incorrectly sized unit, or a malfunctioning thermostat. In many cases, homeowners can address the problem with basic maintenance or adjustments. However, short cycling can also signal more serious mechanical problems such as refrigerant leaks, electrical issues, or compressor failure. These complex issues typically require a professional technician’s diagnosis and repair to ensure the system is operating safely and efficiently. Ignoring short cycling can lead to increased energy bills, reduced comfort, and long-term damage to your HVAC system.

These issues can confuse your system’s internal sensors or limit airflow, which causes the furnace to shut off prematurely. Addressing them early can restore your comfort and save on energy bills.

Ignoring the problem can lead to bigger issues than just inconvenience. Over time, your furnace works harder than necessary, leading to premature wear and a reduced lifespan. It may also cause your heating bills to rise noticeably, since the system is constantly starting up, which uses more energy than continuous operation.

Additionally, short cycling often results in uneven heating—leaving some rooms too cold and others too warm. In severe cases, it may even trip safety switches or damage sensitive components, especially if overheating occurs regularly.

To avoid these risks, it’s best to call in professionals like Ace Appliance Heating and Cooling at the first sign of frequent cycling.

When you contact us about a furnace that won’t stay on, our licensed HVAC technicians perform a detailed system check. We examine your thermostat settings, air filter, ductwork, and internal components to determine the root cause of the short cycling.

Sometimes it’s as simple as replacing a dirty filter or relocating a thermostat away from a heat source. Other times, we may need to clean flame sensors, adjust blower speeds, or troubleshoot more complex electrical or gas control issues.

We never offer guesswork—only clear solutions and honest recommendations based on years of hands-on HVAC experience. Our goal is to keep your furnace running safely, efficiently, and reliably all season long.

If your furnace is cycling more than 3–4 times per hour, it’s time to call the experts. Even if your home still feels warm, the extra stress on your system isn’t worth the long-term cost. Scheduling a professional inspection now can prevent expensive breakdowns later.

At Ace Appliance Heating and Cooling, we respond quickly, diagnose precisely, and provide affordable repairs to get your system back on track. Trust us to keep your home comfortable and your furnace working like it should.

If your air conditioning system is leaking refrigerant, you may be tempted to continue running it to stay cool—especially during a heatwave. But doing so can lead to more harm than good. Refrigerant is essential for your AC system to remove heat from your home. Without the proper level of refrigerant, the system can’t function efficiently or safely.

At ACE Appliance Heating and Cooling, we get this question all the time, and the short answer is: no, you shouldn’t run your AC with a refrigerant leak. Not only does it reduce cooling performance, but it can also damage internal components, raise energy bills, and create safety concerns. Addressing the problem early can save you hundreds—if not thousands—in repair costs.

Ignoring the leak can result in a total system breakdown, possibly requiring a full compressor replacement or even a new AC unit. That’s why it’s crucial to understand the warning signs, associated risks, and what steps to take when you suspect a refrigerant leak in your HVAC system.

A refrigerant leak doesn’t always make itself obvious right away. In fact, many homeowners may not realize there’s an issue until their air conditioner begins to underperform. However, there are several common warning signs that can suggest your AC system is leaking refrigerant and needs attention. Recognizing these early indicators can help prevent further damage and avoid a complete system breakdown:

It’s important to note that refrigerant does not “run out” like fuel—it only escapes when there is a leak. If you see any of these signs, call Ace Appliance Heating and Cooling right away for diagnostics and repair. Prompt action helps prevent more expensive system damage and keeps your home comfortable.

Running your AC unit while it’s leaking refrigerant may seem harmless in the short term, but it puts excessive stress on every part of the system. The compressor—the heart of the unit—is especially vulnerable to overheating and failure. Once damaged, replacing it can be as costly as installing a new system.

Low refrigerant levels also reduce the cooling capacity of your unit. That means it will run longer and harder, leading to higher utility bills. Meanwhile, moisture can enter the system through the leak, causing corrosion and internal contamination. These conditions dramatically shorten the lifespan of your HVAC system.

Finally, depending on the type of refrigerant used, leaks can also pose environmental and health risks. Some refrigerants are greenhouse gases, while others can displace oxygen in enclosed spaces if leaked in large quantities.

If you suspect a refrigerant leak, it’s not just a maintenance issue—it’s a system emergency. The sooner you schedule a service call, the better the outcome for your comfort, budget, and HVAC longevity.

First, don’t panic—but don’t wait either. Turn off the AC system to prevent further damage, especially if you notice ice buildup or weak airflow. Avoid DIY repairs, as refrigerant handling requires EPA-certified technicians with specialized tools and safety protocols.

At Ace Appliance Heating and Cooling, our licensed HVAC technicians use state-of-the-art leak detection methods to locate the exact source of the issue. We’ll repair the leak, recharge your system with the correct refrigerant type, and test for pressure and performance.

Preventative care is also essential. Scheduling routine maintenance allows us to catch refrigerant issues early, clean coils, and keep your system running efficiently. A small leak today could be a major repair tomorrow.

Trying to operate an AC system with a refrigerant leak is like running a car without oil—it may work briefly, but damage is inevitable. Professional HVAC service ensures the leak is handled correctly and that your system operates within manufacturer specifications.

Our team at Ace Appliance Heating and Cooling is trained, insured, and equipped to handle refrigerant issues quickly and safely. We provide transparent pricing, honest diagnostics, and top-tier service to restore your cooling system’s performance and lifespan.

When your AC goes on the fritz, it can feel like your whole home climate is at risk—and time suddenly becomes precious. In most cases, minor repairs like replacing a capacitor, fixing a refrigerant leak, or cleaning coils can be completed in under an hour. However, more complex issues—such as replacing a compressor, resolving extensive ductwork problems, or installing new components—can take several hours or even span a full day.

Below are some of the most common AC repairs and what they typically involve, so you know what to expect when the technician arrives.

Not all AC problems are created equal—some can be resolved quickly, while others require more time and resources. Minor repairs, like swapping out a faulty capacitor or cleaning a dirty outdoor coil, are typically straightforward and can often be handled in a single visit. These fixes are common and generally take less than an hour for a skilled technician.

Mid-level repairs, such as recharging low refrigerant levels or addressing a small leak, take a bit more time. These tasks often require pressure testing, leak detection, and careful handling of refrigerant in compliance with EPA regulations. While still manageable within one visit, they demand more precision and tools than basic fixes.

Major repairs—like replacing a failed compressor, blower motor, or diagnosing complex electrical board issues—can be time-intensive and may not be completed the same day. In some cases, additional parts must be ordered or further diagnostics are required, making a follow-up appointment necessary to fully resolve the issue.

Repair timing depends on several key factors. First, diagnosing the issue accurately can sometimes take longer than the physical repair. Unexpected findings—like rusted connections or multiple simultaneous faults—can extend the schedule. We remain focused on safety and precision, which occasionally means a longer visit but a better overall solution.

Your air conditioner is running, but instead of cool relief, you’re greeted with warm air—this is one of the most common (and frustrating) AC issues homeowners face during the summer. While it may seem like your system is functioning, warm air is a clear signal something is wrong internally, even if the fan is still blowing. Left unchecked, this issue can lead to bigger problems and higher repair bills.

In most cases, warm air blowing from your AC is tied to a handful of root causes like refrigerant issues, electrical failures, thermostat settings, or blocked airflow. Some of these are simple to correct, but others require immediate professional attention to prevent a complete system failure. Knowing what to look for can help you take quick action and stay cool when temperatures rise.

At ACE Appliance Heating and Cooling, we’ve helped hundreds of homeowners fix this exact issue. From San Fernando Valley to Conejo Valley, our licensed technicians deliver fast, honest AC repairs with zero pressure or upselling. Here’s what may be going wrong with your system—and what you should do about it.

There are several possible reasons your air conditioner is running but not cooling your home properly. Some are simple DIY fixes, while others require professional service to avoid worsening the problem.

If your air conditioner is running but still blowing warm air, it’s more than just an inconvenience—it’s a clear sign that something isn’t functioning as it should. Ignoring the warning signs can lead to higher energy bills, worsening damage, or even a complete system breakdown. Whether it’s something simple like a clogged filter or a more serious issue like low refrigerant or a failing component, addressing the problem early can save you time, money, and frustration.

Our experienced technicians at ACE Appliance Heating and Cooling are trained to diagnose the root cause quickly and accurately. We understand how important it is to restore your comfort, especially during the peak of summer heat. That’s why we offer prompt, honest, and effective AC repair services with no pressure or upsells—just straightforward solutions that work.

Once you’ve confirmed the thermostat is correctly set to “cool,” the next step is to check your air filter. A clogged filter restricts airflow and can cause your system to overheat or freeze up. If the filter is clean, listen for unusual sounds, check the outdoor unit for debris, and make sure your circuit breaker hasn’t tripped. Sometimes, the solution is simple—but when in doubt, call a professional.

Refrigerant issues are one of the leading causes of warm air. If your system is low on refrigerant, it can’t absorb and release heat properly. Unfortunately, refrigerant doesn’t “run out” naturally, so if levels are low, it usually means there’s a leak. This requires immediate attention and EPA-certified handling to ensure safe and legal repair.

Another common issue is frozen evaporator coils, which can happen when airflow is blocked or refrigerant levels drop. When coils freeze, your system may still run, but it can’t cool your air. You might even see ice buildup on the copper lines near your unit. If you notice this, turn off the system and call a technician right away.

At ACE Appliance Heating and Cooling, we follow a step-by-step process to pinpoint the exact cause of the issue. First, we check your thermostat and electrical connections to rule out user error or wiring problems. Next, we inspect the air filter, indoor coils, and refrigerant lines for blockages, freezing, or leaks. This comprehensive approach helps us get your AC cooling again quickly—without unnecessary parts or replacements.

Our team arrives fully equipped with the tools, meters, and EPA-certified refrigerants needed to make most repairs on the spot. If your system has a serious problem, we’ll walk you through your options clearly—without pressure.
