Blank screen, wrong temperatures, or ready for a smart thermostat? We install and replace thermostats for heat pumps, furnaces and dual-fuel systems, wire them correctly and show you how to use them.
Available in: Winchester & Wilmington, and Norfolk from January 2027
Heating and cooling service from our Norfolk branch starts January 1, 2027. Until then, our Norfolk team is here for plumbing, drains, boilers, gas lines, septic and wells. Call the Norfolk office with any questions.
It happens more than you'd think. Heat pumps and dual-fuel systems need the right wiring and settings.
Thermostat installation sounds simple, but a heat pump needs control of its reversing valve and backup heat, a dual-fuel system has to switch between the heat pump and the furnace, and many smart thermostats need a power wire older systems don't have. Get it wrong, and the system runs on expensive backup heat or not at all.
Your technician matches the thermostat to your equipment, wires and configures it, tests heating and cooling, and shows you how to set a schedule. If the thermostat isn't the real problem, we'll find what is.

Installation, cost and settings.
On a simple system, often yes. Heat pumps, dual-fuel systems and thermostats that need a new power wire are trickier, and a wrong connection can leave you on expensive backup heat or damage a control board.
A blank screen, a system that won't turn on or off, temperatures that don't match the setting, or short cycling. Replace the batteries first. If that doesn't fix it, the thermostat or its wiring may be at fault.
Pick a comfortable temperature and leave it, or use small setbacks of two or three degrees. Big setbacks make the heat pump call for backup heat to catch up, which costs more. Smart thermostats designed for heat pumps manage this for you.
Usually under an hour for a straight swap. Running a new power wire or setting up a dual-fuel or zoned system takes longer.
