Evans Air Conditioning & Heating | Experienced HVAC Services in Creve Coeur, MO

Proper sizing is critical for efficiency and comfort. Our technicians perform a detailed Manual J load calculation, which factors in your home's square footage, insulation, window placement, and local climate data specific to the Creve Coeur area. This prevents the common issues of an oversized system that short-cycles or an undersized one that struggles to maintain temperature, ensuring your new unit runs optimally and keeps energy bills in check.

A faulty reversing valve, which switches your system between heating and cooling modes, often shows itself through inconsistent temperatures. You might notice it blowing cool air when set to heat, or warm air when set to cool. Other signs include a hissing sound or the system being stuck in one mode.

Our goal is to resolve the issue correctly the first time, minimizing downtime for your home or business. We stand behind our repair work and are committed to getting your system back to reliable operation as quickly as possible.
