Is a Thermostat Replacement in Your Future?

Thermostats are an important part of your home’s infrastructure that you may not think much of until they experience an issue. Often, older thermostats are working past their estimated lifespan, and that is when they begin to show signs they may warrant a replacement.

No matter the age of your thermostat, look out for:

  • Inaccurate Readings: The device displays a temperature that doesn’t match the actual air in the room.
  • Unresponsive Interface: The screen stays blank or buttons fail to trigger the air conditioner.
  • Short Cycling: Your HVAC system turns on and off too frequently due to faulty sensor data.
  • High Energy Bills: An outdated controller causes your unit to run longer than necessary.
  • Obsolete Technology: Older manual sliders lack the precision of modern digital controls.

Our Thermostat Services

We sync your controls with your heating and cooling hardware to ensure every signal reaches your unit instantly.

Thermostat Repair

We diagnose communication issues between the thermostat and the HVAC control board. Our technicians identify loose wiring and replace faulty internal components to get your system back online. If a repair is not cost-effective, we provide clear options for a modern upgrade.

During a standard maintenance visit, our team verifies that your thermostat is leveled and calibrated. We check for software updates on smart models to prevent system strain and ensure peak efficiency.

Installation & Replacement

We install a wide range of systems, including programmable and Wi-Fi-enabled smart thermostats.

Charlie M was wonderful. Drove over an hour to squeeze me in. My water heater was beyond repair and he explained everything thoroughly. The tank could not be fixed due to age. Charlie was thorough in his explanation of my options and outlined everything to expect with the new install. He encountered a small hiccup - no fault of his own - and went above and beyond to make sure the job was completed in a timely fashion and kept me informed every step of the way. I could not be happier with the work he did and the quality of the service he provided. Exceptional

Working with R S Andrews is always a breath of fresh air. The technician-Kwame Kilgore, was excellent!!! He was very personable, thorough and informative. He fixed my thermostat where I can easily use it. He reviewed and explained his findings and emailed them to me. I will be asking for him to return for my spring checkup.
