HVAC Maintenance and Tune-Ups in Dunwoody, GA

Here's the thing about breakdowns: they're rarely sudden. They're the last step of a slow slide nobody was watching. A capacitor loses a little strength every summer until one blistering afternoon it can't start the compressor. A drain line collects slime until the float switch shuts everything off, or worse, the pan spills over. An outdoor coil matted with pollen and cottonwood fluff makes the whole system strain and run hot. A flame sensor slowly gets coated until the furnace starts cutting out on cold nights. A tune-up catches each of those while it's still a small fix. In spring the technician focuses on cooling: rinsing the outdoor coil, flushing the drain, testing capacitors and contactors and measuring refrigerant and airflow. In fall it's heating's turn: burners, flame sensor, igniter, venting and safety controls, plus the blower and filter. Heat pumps get attention both seasons, since they work all year. Every visit follows a checklist and ends with a written report in everyday language, so you'll know what was done, what the numbers were and what to watch. That's how a tune-up heads off a breakdown.
