OUR PROCESS

How We Handle Thermostat Service in Marietta

1. Confirm Your Appointment

Marietta homeowners get a same-day or next-day window. Free dispatch means no charge just for the visit. You get a text with the tech’s name and photo before they arrive.

2. Test Thermostat Accuracy and Wiring

Our technician checks your thermostat’s temperature reading against a calibrated probe and inspects the wiring connections at the control board. This spring, catching a thermostat that reads two degrees off saves Marietta homeowners from short-cycling through unpredictable March weather.

3. Walk You Through the Options

If a replacement makes sense, we show you smart thermostat options and explain compatibility with your system. All pricing is flat-rate and approved by you before work starts.

4. Verify the System Responds

After installation or repair, we run the system through heating and cooling modes to confirm the thermostat communicates correctly. All work is guaranteed in writing.
