Centennial Hills grew fast in the late 2000s and early 2010s, which means a lot of homes now have systems that are 10–15 years old. Builder-grade equipment runs fine for the first several years, then starts showing its age: capacitors fail, coils lose efficiency, refrigerant charge drifts.
The first sign is usually a utility bill that creeps up without a clear explanation, or a system that runs longer than it used to. A diagnostic before peak season tells you if it’s a minor tune-up, a targeted repair, or a replacement worth planning for.
Centennial Hills homeowners tend to be proactive about maintenance, and many homes here have rooftop solar. If you have solar or are considering it, HVAC sizing still needs a proper load review. We account for rooftop solar when we talk through sizing, but it doesn’t replace a real load calculation.
