The 5-Point Pre-Purchase Checklist: What Agoura Hills Homeowners Need Before Shopping for High-SEER Systems

n

Before you start comparing energy efficient AC Agoura Hills systems, walk through this critical checklist. Missing even one step can cost you thousands in wasted efficiency or prevent you from qualifying for available rebates. First, obtain at least 12 months of electricity bills from Southern California Edison to establish your baseline cooling costs—current average residential rates hover around 34.5 cents per kWh, which makes efficiency calculations dramatically different than they were even five years ago. Second, have a licensed contractor perform a Manual J load calculation specific to your home’s square footage, insulation, window orientation, and Agoura Hills’ Mediterranean climate. Third, verify your existing ductwork condition—leaky ducts can waste 20–30% of conditioned air regardless of your new system’s SEER rating. Fourth, confirm your electrical panel can handle variable-speed systems, which require different amperage than older single-stage units. Fifth, document your home’s current HVAC age and efficiency rating to calculate realistic ROI timelines and determine whether you qualify for federal tax credits by replacing equipment over 10 years old.
