“Scheduling around our limited weekends at the cottage was effortless. They finished the ductless install ahead of schedule, labeled the breaker, and texted photos of the completed work.”

Thermostat Repair and Replacement, Done Right the First Time
Strathroy Heating & Cooling: A thermostat that misreads by a few degrees quietly inflates your heating bills all winter. Our technicians diagnose faulty sensors, worn wiring, and failing controls, then repair or replace them with properly calibrated units that put an end to the guessing.
Why Homeowners Call Us
Furnace ignoring the thermostat on the coldest Strathroy night?
A thermostat running a few degrees hot makes the furnace overspend all winter. Correct calibration or a smart replacement brings bills back in line.
Precise Diagnostics on Every Visit
We measure voltage at the thermostat, check transformer output, and verify the call for heat end to end. You see the readings yourself, which is why our repairs hold up season after season.
Protection for the Equipment Downstream
Every false signal from a bad thermostat sends your furnace, boiler, or heat pump through needless cycles. Keeping the control side healthy is the cheapest prevention an HVAC system can get.
Free Second Opinions, Any Time
Told elsewhere that you need a full replacement? Show us the quote. We will test the thermostat ourselves and tell you honestly whether a repair can carry it another season.
FAQ
Thermostat Repair & Replacement in Strathroy: Common Questions
How much does thermostat repair or replacement cost?
It depends on the fault and the thermostat type. A simple sensor fix runs far below a smart model with installation, and our estimates are always free.
How quickly can a thermostat be repaired or replaced?
Urgent no-heat calls jump the queue, especially in freezing weather. If the thermostat is the culprit, restoring control is often one of the faster fixes we make.
Should I repair my thermostat or replace it with a new one?
Under ten years old with a fixable fault? Repair it. Older, or paired with a new high-efficiency furnace or heat pump? A smart replacement usually makes more sense.
