Heat Pump Repair in New Carrollton, Maryland
Prince George's County · 24 hour emergency service
Heat pump repair, replacement and maintenance in New Carrollton, across the 1950s and 1960s ramblers and split levels and the garden apartments near the Metro. Much of this housing is all electric, so what the heat pump does in January lands straight on the Pepco bill.
Why people here call us.
New Carrollton has a higher share of all-electric housing than most of the county, particularly in the garden apartments and condominiums clustered near the Metro and Amtrak station and along the Annapolis Rd corridor. A lot of those units are tenant occupied, which changes who calls and what they need. A property manager wants to know whether a unit can be repaired today or has to be replaced before the next tenant moves in.
A resident wants to know why the heat feels lukewarm and why the electric bill climbed. Those are usually the same problem viewed from two sides. When a heat pump falls back on its auxiliary electric strip heat, the home stays warm and the cost rises quietly, so nothing gets reported as broken until the bill arrives.
On the single family side, the ramblers and split levels off Good Luck Rd and Riverdale Rd bring the other classic issue: original ductwork under newer equipment, where the airflow a heat pump depends on was never available in the first place.
What New Carrollton homes ask of this job.
New Carrollton was built out fast in the 1950s and 1960s and the housing is consistent: brick and frame ramblers, split levels and split foyers on quarter acre lots in 20784, plus a substantial stock of two and three story garden apartment buildings and later condominiums. The ramblers typically run 1,100 to 1,600 square feet on a slab or over a basement, with duct in a crawl space or hung under the basement ceiling, and that duct is very often original even where the equipment is new.
A heat pump moving air in the low 90s cannot afford the leakage and crushed flex runs that a big furnace could paper over with hotter air. The split levels off Good Luck Rd and Lamont Dr add their own problem, because one thermostat is controlling three or four half-levels with different loads, and whichever level satisfies first decides when the compressor stops.
Near the station, along Harkins Rd, Garden City Dr and Ellin Rd, apartment and condominium units run air handlers in tight closets with electric strip heat built in, and replacement equipment has to fit a footprint that cannot change. Carrollan Gardens sits between the two.
The problems that keep coming up.
- Apartment heat pumps near the Metro running on strip heat because the compressor or the reversing valve failed months ago and the unit still blows warm air.
- Thermostats in rental units switched to emergency heat by a previous tenant and never switched back, which doubles a Pepco bill without anything actually failing.
- Original crawl space duct under a newer heat pump in ramblers off Riverdale Rd, leaking enough that the far bedrooms never satisfy in either season.
- Split level systems short cycling on the level that holds the thermostat, leaving the top floor hot in summer and the lower level cold in winter.
- Defrost meltwater pooling under outdoor units set on pads that have settled, undermining the pad further and tipping the unit out of level.
How the appointment runs.
A visit here covers both modes and then the thermostat, in that order. We verify refrigerant charge with superheat and subcool, confirm the reversing valve actually shifts rather than partially seating, read the defrost control and coil sensor, and measure the temperature split across the indoor coil in heating and in cooling.
Then we check how the strip heat is staged and whether an outdoor lockout was ever configured, because in New Carrollton that one setting is often the difference between a normal winter bill and a shocking one. In apartment and condominium units we measure the closet, the door opening and the electrical feed on the first visit, since replacement equipment has to fit an existing footprint and breaker.
If you are a property manager coordinating access, say so when you call. For ramblers we get into the crawl space and look at the duct.

Common questions.
What is the difference between auxiliary heat and emergency heat on my thermostat?
Auxiliary heat is the electric strip heat coming on automatically to help the compressor when it cannot keep up. Emergency heat means you have shut the compressor off entirely and are heating on the strips alone, which is meant for a broken heat pump, not a cold day. Left there all winter, it costs several times what the heat pump would.
The apartment heat pump is old. Can it be replaced without changing the closet?
Usually yes, but it has to be measured rather than assumed. Air handler cabinets come in fixed widths and heights, the closet door opening limits what can be carried in, and the existing breaker and wire size limit which strip heat package can go in. We measure all three on the first visit so the quote matches what fits.
Why does my heat pump blow air that feels cool even in heating mode?
That is normal for a working heat pump. It delivers a large volume of air in the 90 degree range rather than short blasts of 130 degree air the way a furnace does, and 90 degrees feels cool against skin at 98. Real trouble looks different: a small temperature rise across the coil, or strip heat carrying the load.
