Thermostat Installation & Repair in Washington, DC

How we handle it

Smart thermostat installs include configuring it for your exact system: furnace, heat pump, boiler or dual fuel.

Northwest DC homes with heat pumps need thermostats set up for auxiliary heat. The wrong settings make electric strips run too often and raise the bill.

Systems we find in Washington

Heating here is a mix of original boilers feeding cast iron radiators, gas furnaces in rowhouse basements, and heat pumps added during renovations. Central air was often retrofitted later, so many homes run a rooftop or rear-patio condenser with an air handler squeezed into an attic or closet.

Older Northwest DC homes often have two-wire thermostat cable that predates central air. We add a proper common wire instead of adapters so smart thermostats stay powered.

How the seasons hit Washington

Summer heat in Northwest DC regularly pushes past 95 degrees with heavy humidity, which is hard on rooftop condensers. Winter brings stretches in the teens, and that is when original boilers and older furnaces tend to give out.
