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.

How we handle it

Heating tune-ups focus on combustion safety and ignition; cooling tune-ups focus on coils, charge and drainage.

For a Petworth tune-up, have the last filter size handy. Many rowhouse returns take odd sizes like 14 by 25, and bringing the right filter saves a second trip.

Petworth tune-ups on rooftop condensers include checking the unit's mounting and the roof seal around the line set. A loose stand or worn seal can lead to roof leaks that show up long after the visit.

Petworth homes

Petworth is block after block of 1910s to 1930s brick porch-front rowhouses, plus a growing number of condo conversions along Georgia Avenue.

Petworth tune-ups often turn up the same few things: a dusty flame sensor, a slow condensate drain and a filter slot that lets air bypass the filter. We also look at the radiator valves and the boiler pressure gauge in homes that still have them, since those are easy to overlook.

Pricing

Tune-ups are priced upfront before we arrive.
