Top-rated independent heating and cooling across Palm Beach County and the Treasure Coast
Thermostat Installation — Book a Visit Today
We install and replace thermostats, add smart controls and set up zoning across the region. Most calls start the same way: the screen is blank, the temperature reading is off by several degrees, or a new thermostat was wired in and now the AC runs without ever satisfying. Salt air and long cooling seasons are hard on wiring and on low-voltage connections behind the wall plate. On a visit we confirm the thermostat is getting power, check the wiring against your equipment, mount and level the new control, then run a full cooling and heating cycle to prove staging works. If your thermostat is dark or fighting you, call us and describe what the display shows.

Safe things to check first
Worth a look before you call — sometimes it saves you the visit.
- 1Replace the thermostat batteries if the display is dim, blank or flickering.
- 2Confirm the thermostat is set to cool or heat and the fan is on auto, not off.
- 3Check the breaker panel for a tripped breaker serving the indoor unit.
- 4Change a loaded filter and make sure supply and return vents are open, since starved airflow makes a thermostat look wrong.

Can any smart thermostat work with my system?
Not always. Smart thermostats need a common wire for steady power, and some multi-stage or heat pump setups need specific terminals. We check your existing wiring and equipment first, then tell you which controls will actually run your system properly.
How long does a thermostat replacement take?
A straight swap on existing wiring is usually short work. We allow extra time to label wires, mount the plate level, configure the control for your equipment type, then run a cooling and heating cycle to confirm every stage responds.
Does the thermostat location matter?
It matters a lot. A thermostat in direct sun, above a lamp or near a supply vent reads the wrong temperature and short cycles your system. We look for an interior wall with steady air movement and away from doors.
What is zoning and do I need it?
Zoning uses dampers and multiple thermostats so different parts of the house get conditioned separately. It helps two-story homes and additions where one room is always uncomfortable. We check duct layout first, because zoning only works with adequate airflow.
Will a new thermostat fix my cooling problem?
Sometimes. A failed thermostat can cause short cycling or a system that never starts. But weak cooling often traces to refrigerant, airflow or a failing outdoor unit. We test the control and the equipment before recommending a replacement.
My thermostat is corroded at the terminals. Now what?
Coastal and humid air corrodes low-voltage connections, and a poor contact makes a system act erratically. We clean or re-terminate the wiring, check the run back to the air handler, and replace the control if the board is damaged.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form with what you hear, smell or feel. Warm air, ice on the lineset, a humming outdoor unit. That detail helps us load the right parts before we drive out.
- Step 2
We diagnose on site
We check the thermostat, the air handler, the condenser and the electrical side, then measure what the system is actually doing. You get a plain explanation of the fault and the repair options before we start.
- Step 3
We repair and verify
Once the repair is done we run the system and confirm temperature split, drainage and airflow at the vents. If a part is on order, we tell you the timeline instead of leaving you guessing.

Why homeowners call us
- We plan for salt airCoastal humidity and salt eat coils, contactors and cabinet screws. We look for corrosion during every visit and treat it as part of the diagnosis, not an afterthought, so a repaired system does not fail again in the same spot.
- Built for constant runtimeFlorida systems run most of the year, so bearings, capacitors and drain lines wear faster than the manual suggests. We size repairs around that reality and point out the components likely to be next in line.
- Old houses and new onesIsland properties often hide ductwork in tight, damp spaces, while tract homes tend to have short, undersized returns. We have worked both and adjust the approach rather than forcing one standard fix.
- Clear talk, no upsell theatreWe tell you what failed, what it takes to fix it, and whether repair or replacement makes more sense for the age of the equipment. If a repair will hold, we say so and get on with it.
