What our thermostat services covers
Smart thermostat installation
Smart thermostats earn their keep when they are wired and configured right, including the common wire many older homes lack. We install, connect and walk you through the app before we leave.
Zoning and control upgrades
Two-story colonials with one thermostat live with a hot upstairs and a cold downstairs. Zoning dampers and a second control can fix what no single thermostat ever will.

Questions callers ask about thermostat services
How fast can you come out?
Call as early in the day as you can. No-heat and no-cooling emergencies are placed first, and we give you a straight arrival window on the call, not a vague promise.
Do you charge for the visit?
Estimates on new systems are free. For repairs, any diagnostic charge is explained on the call before anyone is dispatched, and the repair itself is priced in writing before it starts, so there are no surprises.
What should I do before you arrive?
Check the thermostat is set right and the filter is not clogged solid, both save real visits. If you smell burning, hear loud electrical buzzing or your CO alarm sounds, switch the system off and call us from a safe spot.
My new thermostat shows no power. What happened?
On many systems the thermostat is powered from the furnace control board, and a blown low-voltage fuse or a missing common wire after a DIY swap is the classic cause. It is a small fix once tested, and we check the board before replacing anything expensive.
