Thermostat repair can make a good AC look broken
The screen is blank, or it says 74 and the house feels like 80. A bad thermostat makes a healthy AC look broken. Thermostat repair is a cheap place to start.
We check the wiring and power first. Then we repair it, replace it, or put in a smart one.
Smart thermostats, set up right
We install compatible smart thermostats and test both heating and cooling before we leave. A smart thermostat only saves money when it's wired correctly, has a common wire where it needs one, and is programmed for how you actually live.
What the visit covers
- Thermostat diagnostics
- Replacement of failing thermostats
- Smart thermostat installs
- Wiring and common-wire fixes

Thermostat replacement, Port St. Lucie
A thermostat that reads wrong makes the unit run longer than it has to. We replaced this one and checked it against a real temperature reading.
What happens when you call
Tell us what the thermostat shows and what the house feels like. JD usually picks up. If he's under a house or on a roof, someone calls you back. Ask about the diagnostic fee and we'll tell you before anyone drives out.
