Heat Pump Repair, Maintenance & Installation
Heat pump repair, maintenance and installation across Washington, D.C. and Maryland — efficient all-in-one heating and cooling, all makes and models.
A heat pump heats and cools your home from a single system — efficient, all-electric comfort that’s a great fit for many Washington, D.C. and Maryland homes. Our NATE-certified team services, repairs and installs every make and model.
Heat pumps work differently from a gas furnace: instead of burning fuel, they move heat — pulling warmth out of the outside air to heat your home in winter, then reversing to cool it in summer. Because one system runs year-round, maintenance and proper setup matter more, not less. All-Pro Services has 40+ years in the area and is a factory-authorized dealer for Lennox, Trane, American Standard, Rheem, Ruud, Bryant, Carrier and York.

Year-round systems need a checkup each season; we keep the unit off its expensive backup heat and running efficiently.
Heat Pump Installation
Right-sized, high-efficiency heat pumps — including dual-fuel setups — installed with a free estimate.
Why is my heat pump’s electric bill so high?
This is the most common heat pump question we get, and the usual culprit is auxiliary (or “emergency”) heat. When a heat pump can’t keep up — or isn’t working right — it falls back on electric resistance heat strips, the most expensive way to warm a home. A heat pump that’s low on refrigerant, has a failing outdoor unit, or is stuck calling for aux heat will quietly run up a shocking bill while the house still feels warm. If your winter electric bill spiked, that’s worth a service visit; it’s frequently a repair rather than a replacement.
Steam, ice, and the defrost cycle (this is normal)
On cold, damp days you may see your outdoor unit steaming or lightly iced, then briefly blowing cool air indoors. That’s the defrost cycle — the system melting frost off the outdoor coil — and it’s completely normal. What’s not normal is the unit encased in thick ice, or defrosting constantly; those point to a problem worth diagnosing.
Do heat pumps work in our winters?
Yes. Modern heat pumps perform well through D.C. and Maryland winters, and today’s units are dramatically more efficient than models from the 1990s and 2000s. Efficiency is rated by SEER2 for cooling and HSPF2 for heating — higher is better on both. For homes that want a backup for the coldest snaps, a dual-fuel system pairs a heat pump with a gas furnace, letting each run when it’s most economical. We’ll help you decide whether a straight heat pump, a dual-fuel setup, or a gas furnace is the better fit for your home.
Repair or replace your heat pump?
Heat pumps typically last about 12–15 years. Because they run far more hours per year than a furnace, regular maintenance has an outsized effect on both lifespan and your energy bills — which is exactly what our maintenance agreements are built for, covering both the heating and cooling sides with priority service and 20% off repairs.
Heat pump FAQs
Why did my electric bill spike this winter when the house is still warm?
With a heat pump, that usually means the system is leaning on its auxiliary electric heat — the priciest way to heat. Causes range from low refrigerant to a failing outdoor unit to a thermostat or sensor issue. A service visit pinpoints it, and it’s often a fix rather than a replacement.
Why is my outdoor unit steaming or covered in ice?
Light steam or a thin frost that clears within a few minutes is the normal defrost cycle. Thick ice that builds up, or defrosting that never seems to stop, isn’t normal and should be checked.
Heat pump or gas furnace — which is better?
It depends on your home. A heat pump heats and cools from one efficient all-electric system; a gas furnace delivers very warm air and pairs with a separate A/C. Dual-fuel combines both. We’ll size and price the options for your specific home rather than push one answer.
How long does a heat pump last?
About 12–15 years on average. Because it runs year-round, annual maintenance makes a real difference — a neglected heat pump loses efficiency and leans on costly backup heat.
Do you install dual-fuel systems?
Yes. A dual-fuel system pairs a heat pump with a gas furnace so each runs when it’s most economical — the heat pump in milder weather, the furnace in the coldest snaps. We’ll tell you whether it makes sense for your home.
