OUR PROCESS

What to Expect From Thermostat Service With Us in Kennesaw

1. Get a Fast Confirmation

Kennesaw homeowners get a confirmed slot and a pre-arrival text with the technician’s photo. Free dispatch keeps the visit cost-free.

2. Measure Temperature Differential

We place a calibrated sensor next to your thermostat and compare the reading to actual room temperature. If the gap is more than a degree, we trace the issue back to the sensor, wiring, or placement.

3. Recommend the Right Fix

Sometimes the thermostat just needs recalibration. Other times, a replacement is the better move. We lay out both options with flat-rate pricing this March so Kennesaw homeowners can decide before cooling season.

4. Confirm Communication With the System

We cycle through every mode to verify the thermostat sends the right signals. All work is guaranteed in writing.
