Thermostat repair and replacement in Vero Beach

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

Leaking heat pump replaced, Vero Beach

The heat pump was leaking and the repair would have cost too much to make sense. We gave the homeowner both numbers. They chose to replace it, with no money down on financing, with approved credit.

Good to know

What Vero Beach homeowners ask us

Yes. We check the wiring and power first, then replace a failing thermostat or put in a compatible smart one and test heating and cooling before we leave.
That depends on what failed and on the equipment. We tell you the number after we look at the unit, and if replacing it is on the table, you get both numbers.
No. Everyone here is paid hourly, not on commission. When a repair will hold, that's the recommendation.
Yes. We answer 24/7. Sundays and holidays are billed at double time.
