“Propane costs were killing us every winter. They replaced the furnace with a cold-climate heat pump, explained the operating costs honestly, and the transition was completely painless.”

Why Homeowners Call Us
Thermostat won't turn on or keeps showing the wrong temperature?
A thermostat running a few degrees hot makes the furnace overspend all winter. Correct calibration or a smart replacement brings bills back in line.
Short Cycling Stopped at the Source
A furnace that starts and stops every few minutes usually answers to a faulty thermostat signal. We isolate the cause, repair the control circuit, and end the churn before it wears out your equipment.
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.
Every Repair Backed in Writing
Repairs and installations come with written documentation of what was done and which parts were used. If anything we touched fails, you have our name, our number, and our promise.
FAQ
Thermostat Repair & Replacement in Guelph: Common Questions
How much does thermostat repair or replacement cost?
Honest answer: until we test it, nobody can say. Diagnostics are how we find out, and the quote you get afterwards is free and fixed.
How quickly can a thermostat be repaired or replaced?
Fast, because we show up prepared. Stocked trucks and simple diagnostics mean the vast majority of thermostat jobs are finished the same day we first see them.
Should I repair my thermostat or replace it with a new one?
Weigh the system around it. A new furnace or heat pump often deserves a modern thermostat that can run its stages, something an old unit cannot do.

Real feedback from neighbours we've helped stay comfortable year-round.
“Our AC died just before humid weather settled in and I worried about my mother upstairs. They squeezed us in, fixed the fault, and even followed up afterward.”

“With three shedding cats, our vents were packed with fur. They covered the floors, cleaned each register by hand, and my allergies calmed down within days.”
