If your system is unresponsive or your energy bills are spiking, schedule service with our certified technicians to restore your comfort.

 

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  • High Energy Bills: An outdated controller causes your unit to run longer than necessary.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.

Maintenance & Tune-Ups

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. Our process involves precise wire mapping to ensure your multi-stage heating and cooling functions work correctly. We also provide a complete walkthrough of the new interface so you can manage your energy usage effectively.

Smart Thermostat Integration

Looking to connect your thermostat with your smartphone or home automation system? We install and configure Wi-Fi-enabled models that allow you to manage your home’s climate from anywhere.

Our HVAC system hasn't been serviced for several years so I scheduled R.S. Andrews for an inspection. Calvin was very good at his job and makes a great impression for the company. He made some repairs to our AC unit and we look forward to his return this fall to service the heater part of our HVAC system.
