Thermostat Repair, Replacement, and Upgrades in Flagstaff, AZ
Your thermostat tells your furnace, heat pump, or air conditioner when to run and when to rest. When it fails, reads the wrong temperature, or loses its connection, your whole system can stop working or run far more than it should. Executive Heating & Air Conditioning repairs, replaces, and upgrades thermostats of every type, from basic digital models to Wi-Fi smart thermostats. We make sure your new thermostat is wired correctly, set up for your specific equipment, and easy for you to use.

Why Choose Executive Heating & Air Conditioning
We are a family-owned company with roots in the heating and cooling trade going back to 1988. Many smart thermostats need a dedicated common wire for steady power, and heat pumps and dual-fuel systems need specific settings to run efficiently. Our technicians check your wiring and equipment before installation, so your thermostat works properly from day one. We also confirm that a thermostat problem isn’t really a furnace or control board issue in disguise.
Signs You Need Thermostat Service
Call us if you notice any of these problems:
- A blank or unresponsive display
- The system won’t turn on, or won’t shut off
- Room temperature that doesn’t match the setting
- Short cycling or frequent on and off running
- A smart thermostat that keeps going offline
Our thermostat services include troubleshooting and repair, replacement of failed units, smart thermostat installation, and programming for heat pumps and multi-stage systems. A properly set smart thermostat can lower energy use by adjusting temperatures while you sleep or are away, which adds up over a long Flagstaff heating season. Some older smart thermostats no longer receive manufacturer support, so if yours has stopped working with its app, it may be time for an upgrade. We are also a Nest Pro installer.
