“A rattling noise from the condenser kept worsening until the fan blade jammed. The tech arrived early, replaced the blade and motor, and the unit now runs whisper quiet.”

Thermostat Repair, Replacement, and Smart Upgrades Near You
Norfolk Heating & Cooling: Thermostats are the command centre of your HVAC system, and a faulty one starves furnaces, boilers, and mini-splits of the signals they need. Across Ontario, our licensed team repairs, recalibrates, and replaces every type, old mercury switches to smart touchscreen models.
Why Homeowners Call Us
Blank screen, no response, and a house that keeps cooling?
Wild temperature swings often trace back to a mislocated thermostat or a drifting sensor. We recalibrate or replace it for steady, even heat.
Emergency Thermostat Repair When Heat Fails
No heat in January is urgent, and we treat it that way. When a failed thermostat cuts off your furnace, our licensed technicians restore control fast, any hour of the day.
Annual Calibration Keeps Readings True
Sensors drift over time, and a thermostat off by two degrees runs your furnace two degrees wrong. A quick calibration check during a tune-up keeps readings honest and runtime efficient.
Technicians Who Explain, Not Upsell
You will know exactly what failed, why it failed, and what your options cost before we proceed. If a new battery solves it, that is the recommendation you get first.
FAQ
Thermostat Repair & Replacement in Norfolk: Common Questions
How much does thermostat repair or replacement cost?
Repairs usually cost less than a replacement, since most faults are wiring, batteries, or sensors. We quote free, in writing, before any work starts.
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?
If the fault is a battery, sensor, or wire, repair wins easily. Replace when the unit is past its service life, incompatible with new equipment, or costing you efficiency.

Real feedback from neighbours we've helped stay comfortable year-round.
“During a brutal humid stretch our AC quit cooling entirely. A tech came the same afternoon, and the house felt dry and comfortable again by dinner.”
