HVAC Maintenance in Peachtree Corners

Ask any tech on my crew where July breakdowns come from and they will tell you: April. A capacitor that tests a little weak in spring is the one that gives out on the hottest weekend of summer. A coil that is half packed with pollen in spring is the reason the upstairs never cools off in August. Drain lines grow clogs slowly, flame sensors pick up a film slowly and contactor points pit slowly, and all of it is easy and cheap to handle while the system is still running. That is what a checkup is for. The spring visit is about cooling: we wash the condenser coil, look at the indoor coil and its pan, blow out the drain line and test the float switch, meter the capacitors, contactor and motors, take refrigerant readings and the temperature drop across the coil, and check the air coming out of the registers upstairs and down. The fall visit flips to heating: igniter, flame sensor, burners, flue and safety switches on a gas furnace, heat strips on an electric system and a heating run plus a defrost check on a heat pump. Both visits get a new filter and a thermostat check. Before we leave, you get a written rundown of every reading and anything that needs watching, so if something does need work, you can plan it instead of finding out at the worst moment. Heat pumps and commercial rooftop units run in every season, so they should be seen twice a year. And in a two-story house, a clean coil and a healthy blower are often the cheapest way to close the gap between floors.
