Each tune-up is a 21-point inspection performed by a trained technician — not a checkbox left at the door. We clean the coils, replace your filter, verify refrigerant charge, calibrate the thermostat, test capacitors and contactors, measure amp draws, and inspect the heat exchanger and flue. You receive a written report with photos.
Most manufacturers require annual maintenance to keep the warranty valid. A documented Therma Tech service history protects you if you ever need to make a warranty claim — and our maintenance customers consistently see 15–30% lower utility bills than neighbors with the same system.
Ask about our Comfort Club plan: two tune-ups per year (heating + cooling), priority scheduling, no overtime fees, and 10% off any repair. It's the simplest way to forget about HVAC for the next 12 months.
