Thermostat Installation and Repair in South Florida
Articles from the licensed technicians at Service Pros of America, written for South Florida homeowners. Need the service itself? See our thermostat installation page.
What thermostat problems do you fix?
We fix thermostats that go blank, ignore the AC, show the wrong temperature, or lose their settings, and we replace them when repair is not worth it. A licensed technician tests the thermostat and the system it controls, because a thermostat symptom is sometimes a problem somewhere else.
Which symptom sounds like yours?
Blank or dim screen. Many things can cause it. Finding which takes a meter and a technician, not a guess from the wall.
AC does not respond. The thermostat says cool and nothing happens. That could be the thermostat or something in the system.
Wrong temperature. The room feels very different from the display.
Wi-Fi drops. A smart thermostat that keeps going offline.
Error code. The screen shows a code and the AC stays off.

Should I replace or repair?
If the thermostat is old, fails often, or you want better control, replacement is usually the better value. If it is a newer unit that stopped because of a system issue, the system needs the repair. The technician tells you which applies after testing.
What is a smart thermostat worth in Florida?
Cooling is most of the electric bill in South Florida. A smart thermostat lets you set schedules, see run times and adjust from your phone. We supply, install and warranty the units we put in. For Nest specifically, see Google Nest installation.
Why a licensed contractor?
Because the thermostat controls an AC system with high-voltage equipment and refrigerant. A contractor who also repairs AC can tell whether the thermostat is the problem or only the messenger.
What should I do when the thermostat acts strangely?
Write down what you see: blank, error code, wrong number, no response. Note whether the AC runs at all. Tell us when you call. That description helps the technician arrive with the right tools. Do not open the wall unit or the air handler yourself. Low-voltage wiring is easy to damage, and a wrong connection can harm the system.
What do owners tell us after replacement?
The common comment is relief. The thermostat that never matched the room is replaced with one that does, the screen is readable, and the AC responds when asked. For landlords, a reliable thermostat also means fewer tenant calls.

What do owners ask about smart thermostats?
The three common questions: will it work with my system, will it really lower the bill, and will it be hard to use. The answers are usually yes, it helps when set up right, and no. The set-up is what matters, and that is why a technician does it. We also show you the basics before we leave, so the first week is not a puzzle.
