Top-rated independent heating and cooling across South Florida
Thermostat Replacement
We replace failed or outdated thermostats in homes across Florida, and we do it in one visit when the wiring at the wall supports the new control. Homeowners call us when the screen is blank, the temperature reading is off by several degrees, the AC runs and runs without shutting off, or the old unit will not hold a schedule. Give us a call and tell us what the thermostat is doing, or not doing. We will confirm whether replacement is the fix or whether the problem sits further down the system.

What a thermostat replacement involves
We shut power to the air handler at the breaker, pull the old thermostat off the wall, and label every wire before anything comes loose. Then we check what those wires actually go to, because older homes in the region often have a missing common wire or a spliced run from a previous swap. The new control gets mounted level on a clean surface, wired to match the equipment, and powered back up. We run a full cooling cycle and a heat cycle with you standing there watching the vents.the ththermostat or is it your system.the wire count decides.The job usually takes under an hour once wiring is confirmed.
What we check and what we install
Before we sell you anything we read the wire count, the equipment type, and whether you have a heat pump with auxiliary heat, since that changes which controls will work. We check the C wire, the transformer load, and the condition of the wire jacket where humidity has gotten to it. Then we set the new thermostat for your stage count and heat pump configuration, which is where most bad installs go wrong. Programmable, non-programmable, or smart with WiFi, we install what fits the system and how you actually live.tell us your habits.
How we decide replacement is the right call
A thermostat is a cheap part with an outsized ability to look like a broken AC, so we rule it out rather than assume it. If the contacts close and the system responds correctly at the board, the thermostat is fine and the fault is elsewhere. If it reads five degrees off a calibrated meter, drops its settings, or fails to call for cooling with the wiring proven good, we replace it. We will also recommend replacement when the old control cannot manage a heat pump's auxiliary stage properly, because that shows up on every summer and winter bill.

Can I keep my old thermostat wiring for a smart thermostat?
Sometimes. Many smart controls need a common wire for constant power, and older homes across the region often lack one. We check the wire count first and tell you what your wall supports before ordering anything.
My new thermostat is blank. Is it defective?
Usually not. A blank screen after installation often points to a tripped breaker, a full condensate safety switch cutting power, or a loose wire at the air handler. Check the breaker, then call us.
Will a new thermostat fix an AC that will not cool?
Occasionally, yes, if the thermostat is failing to call for cooling. More often the problem is refrigerant, a clogged drain, or a failed contactor. We test the control before we sell you one.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form and describe what changed. Warm air, short cycling, a breaker that keeps tripping, water stains on the ceiling. That detail helps us bring the right parts.
- Step 2
We diagnose on site
A technician checks the thermostat, the electrical side, refrigerant performance, airflow and the condensate line. We find the actual cause instead of swapping parts and hoping the problem stays away.
- Step 3
You approve the repair
We explain what failed, what it takes to fix it, and how long the part is likely to last. Nothing gets replaced until you say go, and we test the system before leaving.

Why homeowners call us
- Built for the salt airCoastal Florida is hard on outdoor equipment. Coils corrode, contactors pit, fan motors seize early. We look for that damage during every air conditioning repair so a small failure does not take the whole system down.
- Condensate lines we actually clearBy late summer, drain lines clog with algae and shut systems off on the float switch. We clear the line, check the pan and the safety switch, and show you what caused the backup.
- Heating tooCold snaps still arrive. We do heating repair and heater repair on heat pumps, strip heat and furnace repair where homes have one, so the system works in January as well as August.
- Plain talk about older systemsIf a repair makes sense, we repair it. If a unit is failing in ways that will keep costing you, we say that too and lay out the options. You decide, not us.
