Thermostat Installation & Repair in Petworth, Washington, DC

Last updated November 5, 2026

Older Petworth houses often have thermostat wiring that predates the current system. We sort that out cleanly. Calls from Sherman Circle to Petworth Metro are answered 24/7.

How the seasons hit Petworth

Petworth top floors heat up fast in July because of flat tar roofs, so upstairs bedrooms are often the first complaint. In January, the coldest rooms are usually the front rooms over the porch.

Signs you need thermostat installation & repair

• Temperature reading wrong
• Smart thermostat missing a C-wire
• Heat pump settings incorrect
• Short cycling

How we handle it

We finish by running heat and cooling from the new thermostat with you.

If a Petworth radiator home also has central air, label which thermostat runs which system before we arrive. It makes rewiring or replacement faster and avoids heat and cooling fighting each other.

Getting to you

Our base sits on Georgia Avenue in Petworth, so most homes between Grant Circle and the Petworth Metro are only a few minutes away. We cover the 20011 area along Georgia Avenue, Upshur Street, Kansas Avenue and Grant Circle.

Many Petworth rowhouses mix radiator heat with a separate AC system, which means two thermostats that should never call at the same time. We wire them so heat and cooling lock each other out, which keeps the boiler and the AC from fighting over the same rooms.

Pricing

You can supply your own smart thermostat or we can recommend one. Either way, the price is set first.
