“Our condenser only clicked when starting and I braced for a big bill. It was a failed capacitor, swapped out in thirty minutes, and the unit has started perfectly since.”

Why Homeowners Call Us
Blank screen, no response, and a house that keeps cooling?
A thermostat running a few degrees hot makes the furnace overspend all winter. Correct calibration or a smart replacement brings bills back in line.
Fast and Accurate Thermostat Repairs
Whether your thermostat won't turn on, shows wrong temperatures, or short cycles, we deliver fast diagnostics and precise repairs that restore consistent comfort and efficient control of your HVAC system.
Seasonal Checkups Catch Faults Early
A thermostat fault in October is an inconvenience; the same fault in February is an emergency. Fall checkups catch dying batteries, corroded wiring, and sticky switches before the deep cold arrives.
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 Newmarket: Common Questions
How much does thermostat repair or replacement cost?
Budget-wise, a repair addresses one fault, while a replacement buys a decade of fresh hardware. We price both paths honestly so you can weigh them side by side.
How quickly can a thermostat be repaired or replaced?
Diagnose, fix, test, done: the rhythm of a typical thermostat repair is measured in hours, not days. We confirm heating and cooling cycles before we leave.
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.
