Heat Pump Repair in Adelphi, Maryland
Prince George's County · 24 hour emergency service
Heat pump repair, replacement and maintenance in Adelphi, where an aging heat pump running on electric strip heat is one of the quietest and most expensive problems in the housing stock. We work with homeowners, owners and property managers here.
Why people here call us.
The heat pump problem we find most often in Adelphi does not announce itself. The house is warm, the system appears to run, and nothing sounds wrong. What has actually happened is that the compressor, the reversing valve or the defrost control failed, and the electric auxiliary heat has quietly taken over the entire heating load. Those strips can draw three times what the compressor does, so the first symptom is a Pepco bill that doubled.
In a rental this can run for months, because the tenant pays the bill and the owner gets the repair call, and the two conversations never quite meet. We check that the compressor is running and doing work, measure refrigerant charge in both modes, and confirm the strips only engage when they should.
Where equipment is genuinely at the end of its life, we say so and size a replacement properly instead of stacking another repair onto a system that will not pay it back. We also check staging and balance point, since a system that hands to the strips at 45 degrees costs money on mild nights.
What Adelphi homes ask of this job.
Adelphi in 20783 built out mostly between the late 1940s and the 1960s: brick and frame ramblers, split-levels and small colonials on modest lots through Lewisdale, Cool Spring, Buck Lodge and Carole Highlands, with garden apartment complexes and townhouse groups filling in along New Hampshire Ave, Riggs Rd, Metzerott Rd and University Blvd. This is Pepco territory, and a good share of the housing is all-electric, which is why heat pumps are everywhere here and why strip heat has such a direct effect on what a household pays each month. The University of Maryland is next door, so many of the single family houses are tenant occupied and held by small landlords, and the person calling about the heat pump is often a property manager working from a tenant complaint.
Original square footage is small, but plenty of these houses added rear additions or finished basements the original system was never sized for, so the equipment has been running past its capacity for years. Garden apartment heat pumps near Riggs Rd and Langley Park tend to fail in groups, since they went in the same year and got the same maintenance.
The problems that keep coming up.
- Compressors that failed months ago on Lewisdale ramblers, with electric strips carrying the whole house and nobody realizing until the Pepco bill arrived.
- Filters unchanged through several tenant turnovers, so airflow drops, the indoor coil freezes in summer and the heat pump underperforms all winter.
- Garden apartment heat pumps near Riggs Rd icing over because the defrost board or the outdoor coil sensor gave out during a wet cold snap.
- Rear additions and finished basements tied into an original duct layout, so those rooms stay cold and the thermostat keeps calling for auxiliary heat.
- Side yard outdoor units on multi-family buildings low on refrigerant for years, which costs more heating capacity in January than it costs cooling in July.
How the appointment runs.
The first thing we establish on an Adelphi heat pump call is whether the compressor is doing any work at all, because a system running on strip heat feels warm and hides the failure completely. We check amp draw on the compressor and the heaters, refrigerant charge by superheat and subcool, temperature split, reversing valve operation, defrost control and the outdoor sensors, then look at the filter, the return path and static pressure.
On a rental we write up what we found in plain language so an owner or property manager can decide without being in the room. Access varies. Ramblers in Lewisdale and Cool Spring usually have the air handler in a basement or utility closet. In the garden apartments off Riggs Rd and University Blvd we may need building management to open a mechanical room, and we coordinate tenant access ahead of the visit.

Common questions.
My Pepco bill doubled but the house feels fine. What happened?
That is the classic sign of a heat pump running entirely on auxiliary electric heat. The strips keep the house warm, so nothing feels wrong, but they use far more electricity than the compressor. The cause is usually a failed compressor, a stuck reversing valve, a defrost fault or a badly low refrigerant charge. It is worth a diagnostic right away.
I rent in Adelphi. Who is responsible for fixing the heat pump?
Under most leases here the owner is responsible for the heating and cooling equipment while the tenant pays the utility. That split is exactly why a failed compressor can go unreported for months. If you rent, report a jump in your electric bill to the owner or manager in writing. We are glad to explain our findings to both parties after a diagnostic.
Is it worth repairing a twenty year old heat pump?
Sometimes. A capacitor, a contactor or a defrost board on an otherwise sound unit is worth fixing. A failed compressor, a leaking coil or an older R-22 system usually is not, because refrigerant cost and parts availability have moved against those systems. We tell you what failed, what the repair involves and what a replacement would mean over the next several winters.
