Old Thermostat Removal
We pull the old unit, label every wire, and inspect the wall plate and base for corrosion or heat damage. If the old thermostat shorted, we check the control board fuse before we mount anything new.
Every install covers the full job, not just the swap. Here is what is included in the flat price, and what we handle as an add-on if your home needs it.
We pull the old unit, label every wire, and inspect the wall plate and base for corrosion or heat damage. If the old thermostat shorted, we check the control board fuse before we mount anything new.
We test each wire with a multimeter for continuity and correct voltage. If your C-wire is missing or dead, we tell you before we start and quote the wire pull as a separate line item.
The new thermostat is mounted level, sealed against the wall to stop attic air from skewing the reading, and torqued to the manufacturer spec. We use wall anchors on drywall and patch any old screw holes.
We set system type, stages, fan delay, swing, and heat pump reversing valve terminal. Then we connect WiFi, link your app, and build a schedule around your actual routine, not a factory default.
We run a full cooling cycle and a full heating cycle, watch amp draw on the compressor and blower motor, and confirm the thermostat reads room temp within half a degree before we leave.
We show you how to change the setpoint, adjust the schedule, and check system status from your phone. You get the login, the model number, and the warranty terms in writing.
Thermostat installation Orlando FL is the licensed removal and replacement of your existing thermostat, including low-voltage wiring checks, C-wire verification, mounting, configuration, and a full system test. It is not just snapping a new unit onto the wall plate. We shut off the air handler, pull the old unit, test each wire with a multimeter, and confirm your new thermostat talks to the compressor, blower motor, and reversing valve before we call the job done.
Orlando summers push your system to run 10 to 14 hours a day, and a thermostat that reads 3 degrees off can add $40 or more to a monthly bill. We see this constantly in older College Park and Baldwin Park homes where the original thermostat is 12 to 15 years old. If you are searching for thermostat installation Orlando FL near me, our techs cover the whole metro and can usually be on-site the same day.
Five steps, no surprises. Here is exactly what happens from the moment you call until the new thermostat is running your system.
Schedule
Call or book online — a real human picks up and confirms a 2-hour arrival window.
Diagnose
Licensed tech inspects on-site, then walks you through the cause and your options.
Fix
The job is completed to code and done right the first time — no shortcuts, no surprises.
Guarantee
Every job backed by a written workmanship warranty — and we stand behind it.
Multimeter
Tests continuity and voltage on every low-voltage wire before we mount the new thermostat. Catches a dead C-wire or a shorted run before it damages the control board.
Clamp Meter
Measures amp draw on the compressor and blower motor during the post-install test cycle. Confirms the system is running within spec, not just turning on.
Manifold Gauges
Used when a thermostat complaint turns out to be a refrigerant issue. We check suction and liquid pressure to rule out a leak or low charge before blaming the thermostat.
Leak Detector
Electronic sniff test on refrigerant lines when we suspect a leak is causing short cycling that looks like a thermostat fault.
18-Gauge Thermostat Wire
Carried on every van for C-wire pulls and wire run replacements. Five-conductor and eight-conductor spools on hand for heat pump and two-stage systems.
Nest, Ecobee, and Honeywell Units
Stocked on the van so we can complete the install in one trip. If your existing thermostat is dead and you want a smart upgrade, we do not have to schedule a return.
ACCA Manual J Load Calculation
When a thermostat install is paired with a new AC, we size the equipment with a Manual J load calc. That tells us the correct tonnage and the right thermostat stages, so the system runs at its rated efficiency instead of short cycling.
NATE-Certified Installation Standards
Our techs follow NATE installation standards for low-voltage wiring, terminal identification, and system commissioning. That means every wire is labeled, every terminal is verified, and every install is documented.
EPA Section 608 Compliance
When a thermostat call turns into a refrigerant issue, we work under EPA Section 608 rules for handling R-410A and R-32 refrigerant. Recovery, recharge, and leak repair all follow the federal standard.
Florida Building Code and ACCA Standards
Every install is code-correct per Florida building code and ACCA standards. We document the model number, the wiring configuration, and the test results on the invoice so you have a record for warranty or resale.

Orlando is a heat pump town. Most homes built after 1990 have a heat pump with electric aux heat, which means the thermostat has to be configured for the correct reversing valve terminal. Get that wrong and the system heats in July. We see it constantly in newer Lake Nona and Dr. Phillips builds where a homeowner swapped the thermostat themselves. Older homes in College Park and Baldwin Park often have two-wire or four-wire runs with no C-wire, so a smart thermostat setup in Orlando Florida usually needs a new wire pull or a common adapter. Summer humidity is the other factor. A thermostat mounted on an exterior wall or in a hallway that gets afternoon sun reads 3 to 5 degrees high, which makes the system short cycle and never fully dehumidify. We relocate those thermostats to interior walls or seal the base against wall cavity air. Winter is mild here, but heat pump defrost cycles still need the thermostat to be set correctly or the aux heat strips run constantly and drive up your bill. If you are looking for a cost to install thermostat Orlando FL quote, we give you a flat number before we start and we test the full system before we leave.
College Park
Many homes here were built in the 1950s and 1960s with two-wire thermostat runs. Most smart thermostat installs need a new C-wire pulled from the air handler.
Lake Nona
Newer construction with heat pumps and two-stage systems. Thermostat configuration matters here, especially the reversing valve terminal and aux heat lockout settings.
Baldwin Park
Tight, well-insulated homes where a thermostat mounted on an exterior wall reads high from afternoon sun. We relocate or seal the base to fix the reading.
Downtown Orlando
Condos and older rentals with limited wall space. We work with the existing wire run and use a wall plate or adapter when the old footprint does not match the new unit.
Winter Park
Mix of older homes and renovations. We often find mismatched thermostats paired with newer equipment, which throttles efficiency until the thermostat is set correctly.
High summer humidity and long AC runtimes
A thermostat that short cycles never lets the evaporator coil run long enough to pull moisture out of the air. We set fan delay and swing to maximize dehumidification during Orlando summers.
Heat pumps with electric aux heat strips
If the thermostat is not configured for the correct reversing valve terminal and aux heat lockout, the strips run constantly in winter and drive up your power bill. We set both correctly.
Attic heat reaching 140 degrees in July
Thermostat wire runs through the attic can degrade over time. We test continuity on every wire and replace any run that shows resistance or heat damage.
Afternoon sun on exterior walls
A thermostat mounted on a sun-loaded wall reads 3 to 5 degrees high. We relocate it to an interior wall or seal the base to stop the false reading.
Most thermostat calls come down to one of these five issues. We diagnose the actual cause instead of guessing and swapping parts.
Problem
Your system short cycles, runs longer than it should, and your power bill climbs $30 to $60 a month. In Orlando heat, a 3-degree error means the AC never really shuts off in July.
Our Fix
We test the thermostat against a calibrated thermometer, check for wall drafts behind the base, and either recalibrate or replace the unit. If the error is caused by a sun-loaded hallway, we relocate the thermostat to a neutral wall.
Problem
A blank display or unresponsive buttons usually means a blown 3-amp fuse, a failed transformer, or a broken wire. Left alone, the system runs on a fixed mode or not at all.
Our Fix
We test the transformer output, check the fuse on the control board, and trace the low-voltage wire run. Most repairs are done in one visit with parts we carry on the van.
Problem
You lose remote control and scheduling, and the unit may revert to a default setpoint. In Orlando, 2.4 GHz interference from neighboring networks is a common cause.
Our Fix
We check signal strength at the thermostat location, confirm the unit is on the 2.4 GHz band, and update firmware. If the wall cavity is blocking signal, we install a WiFi extender or relocate the thermostat.
Problem
The reversing valve is being told the wrong thing. This is a thermostat configuration error, not a refrigerant problem, and it will run your electric bill up fast.
Our Fix
We confirm the O or B terminal setting for your specific heat pump brand, correct the configuration, and test both modes. This is a 15-minute fix once we identify the terminal mismatch.
A new thermostat is the cheapest efficiency upgrade you can make to an Orlando system. Here is what changes when it is installed correctly.
Lower Monthly Cooling Bills
A smart thermostat setup Orlando homeowners use correctly can cut cooling costs 8 to 15 percent. We program setbacks around your work schedule and Florida Power & Light peak hours, so your AC is not fighting the hottest part of the afternoon at full tilt.
Accurate Temperature Control
Old bimetal thermostats drift 2 to 4 degrees over time. A calibrated replacement holds within half a degree, which means your Lake Nona bedroom actually hits 74 when you set it to 74 instead of cycling on and off all night.
Remote Control From Anywhere
WiFi thermostat install Orlando Florida service lets you adjust the temperature from your phone at the airport, at work, or from the couch. You can also get alerts when the system stops responding, which often catches a failing capacitor before it becomes a no-cool call.
Fewer Emergency Repairs
Modern thermostats log runtime and cycle data. When we see short cycling or long runtimes, we can catch a refrigerant leak or clogged drain line early. That turns a $900 compressor replacement into a $180 repair.

Installed a new Ecobee in our Winter Park home and fixed a wiring issue the previous company missed. Tech was on time, explained everything, and the system has run perfectly for six months. Fair price and no upsell.
Yelp ★★★★★4.8
Called about a thermostat that was reading 4 degrees high. They came out same day, found a loose wire, and installed a new Honeywell. Clean work and the tech showed me how to set the schedule. Would use again.
BBB ★★★★★4.9
We manage several rental units and they replaced three thermostats in one morning. Professional, on time, and they sent photos of each finished install. No tenant complaints since. Highly recommend for property managers.
Google ★★★★★5.0
Our Nest would not power on because we had no C-wire. They pulled a new wire run and had it working the same afternoon. Explained the whole process and did not try to sell us anything we did not need.
We have been installing and servicing thermostats in Orlando since 1982. That is 44 years of Florida heat, humidity, and heat pump quirks. Our techs hold NATE certification and work under a Florida HVAC license (Class A). We have installed thousands of Nest, Ecobee, and Honeywell units across Orange County, and we know which models hold up in a 150-degree attic and which ones drop WiFi every August. When a thermostat fails, we diagnose the board, the transformer, and the wire run, not just the faceplate.
Real experiences from customers who chose our Thermostat Installation services.
“Our old thermostat was reading 4 degrees high and our AC ran nonstop. The tech found a loose wire at the base and installed a new Ecobee in about an hour. He set up the schedule around our work hours and showed us the app. Our July bill dropped $62 from the same month last year.”

Homeowner, College Park
“We bought a Nest at a big box store and could not get it to power on. Turned out we had no C-wire. Orlando HVAC Air Conditioning pulled a new wire run and had it working the same afternoon. Fair price, clean work, and they cleaned up the wall plate area better than it was before.”
Priya S.
Homeowner, Lake Nona
“I manage six rental units near 32801 and needed thermostats replaced in three of them. They scheduled all three in one morning, installed Honeywell units, and sent me photos of each finished setup. Tenants have not called about temperature issues since. That is a win for me.”

Real answers to the questions we hear most often from local homeowners and property managers.
A thermostat that reads wrong can look like an AC problem. We diagnose both in one trip, so you are not paying two service calls to fix one issue. Most no-cool calls in Orlando trace back to a capacitor, contactor, or thermostat fault.
View AC RepairWhen your system dies at 9 p.m. in July, we answer. Our emergency techs carry thermostats on the van, so if the fault is the thermostat, we swap it on the spot instead of scheduling a return visit.
View Emergency AC RepairEvery new AC install includes a fresh thermostat matched to the system. We size the unit with a Manual J load calc and set the thermostat to match the equipment stages, so you get the rated efficiency, not a mismatched setup.
View AC Installation & ReplacementOur tune-ups include a thermostat calibration check, battery swap, and wiring inspection. Catching a drifting thermostat at a spring tune-up is cheaper than catching it on an August repair bill.
View AC Maintenance & Tune-UpsHeat pump heating failures often start at the thermostat. If your aux heat runs constantly or the reversing valve never switches, we test the thermostat output first before we open the outdoor unit.
View Heating RepairHeat pumps need a thermostat configured for the correct reversing valve terminal (O or B). Get that wrong and the system heats in summer. We set it right and verify the defrost cycle.
