Heat Pump Repair in Boyds, Clarksburg and Rockville, MD
A heat pump that has stopped heating or cooling the way it used to needs both sides checked, and that is what you get. We test the heating side and the cooling side, then tell you plainly what gave out. Mora Heating & Air repairs heat pumps in Boyds, Clarksburg, Germantown, Gaithersburg and Rockville. A heat pump runs every month of the year, so a fault that shows up in one season is usually about to matter in the next.
It starts with a phone call. You tell us what your system is doing, we set a time, and you hear the diagnostic fee on that same call. Your technician runs both the heating and the cooling side and hands you the findings and the repair price in writing before any work starts.
Signs your heat pump needs a repair
Lukewarm air when it should be heating
The air a heat pump sends out is cooler than what a furnace pushes, but it still has to warm the room. When the air feels neutral or cold and your house keeps getting colder, something is wrong. That usually traces back to the refrigerant, or to the valve that switches the system between heating and cooling.
Ice on the outdoor unit that will not clear
A little frost that melts away on its own is nothing to worry about. A unit buried in ice, or ice that hangs on for hours, means something is wrong with the frost control or the refrigerant charge.
Backup heat that never shuts off
The electric backup coils are built for the coldest stretches and for the few minutes after the unit melts frost off itself. When the auxiliary light stays on for days, the heat pump is not pulling its weight, and your electric bill will make that clear.
Grinding, screeching, or heavy buzzing outside
A mechanical noise from the outdoor unit usually means the compressor, the fan motor, or the contactor. The compressor is the pump that moves refrigerant. Leave it running and these problems only get more expensive.
A breaker that keeps tripping
Trips that repeat point to a compressor that struggles to start, a shorted winding, or worn backup coils. Stop resetting it. Leave the breaker off and have the circuit and the equipment checked.
A sharp climb in winter electric use
A heat pump that is struggling quietly hands the job to its electric backup coils, and those cost much more to run. A sudden rise in your winter electric use is often the first thing you notice.
What a heat pump repair visit looks like
You walk us through it by phone
We ask what your system is doing, which mode it is in, and how old the equipment is. You hear the diagnostic fee on that call, and we set the visit.
Testing on both sides
Your technician reads the pressures, checks the valve that switches it between heat and cool, and runs the frost cycle. Then the compressor and the motors get tested, and we make sure the backup heat comes on.
Findings and price in writing
You see what failed, why it failed, and the repair price in writing before any work starts. If the numbers point toward replacement instead, you hear that straight, on the same visit.
The fix, then a full check
We correct the fault and run the system through heating, cooling, and the frost cycle as the weather allows. You get a record of the readings and everything that was done.
What is normal for a heat pump and what is not
A heat pump does not act like a furnace, and plenty of service calls turn out to be a system behaving exactly as it should. Steam lifting off the outdoor unit in winter is just the frost melting off. Supply air that sits around body temperature and feels cool on your hand is normal for this kind of system. A unit that runs long and steady through cold weather is doing its job.
Here is what is not normal. Ice that builds up and stays. Backup heat that never clicks off. Breakers that trip. Mechanical noise. An indoor temperature that keeps sliding down. Age shapes the repair decision the way it does with any equipment. Valves, control boards, and fan motors are reasonable repairs on a unit under ten to twelve years old. Once a compressor fails past that age, the talk usually turns to replacement, and your technician lays both numbers side by side.
Heat pump repair in Boyds, Clarksburg and Rockville homes
Heat pumps carry more of the heating load around here than most people realize. Out past the gas mains near Boyds, the heat pump is often the only heat in the house. That makes a winter breakdown urgent in a way it is not elsewhere. Those properties sit far apart down long driveways, so we plan the likely parts before we leave rather than costing you a second day. Then the humid summers push that same equipment as an air conditioner, so these units get no time off.
In Clarksburg, the original heat pumps in homes built from the 2000s through the 2020s are hitting their first real failures. Most turn out to be a capacitor, a water safety switch, or a control board. The system itself is usually fine. In the older Rockville ramblers that switched to a heat pump along the way, we often turn up duct restrictions left from the original construction. The Twinbrook and College Gardens returns were too small from day one. An honest repair takes those into account.
The part is usually the symptom
A capacitor rarely dies of old age on its own. It dies because the motor it was starting had to work too hard, and something made it work that hard.
Finding that something is the difference between a repair that holds and a repair that comes back. It is why we look at the whole system before we tell you what it needs.
What is your system actually doing?
If one of these is what you are seeing, start there. It tells you what is probably going on, and whether it is something you can check yourself.
Heat Pump Repair questions, answered
Why is my heat pump blowing cold air in winter?
Start with this. Heat pump air feels cooler than furnace air even when the heating is working right. If the temperature in the house is genuinely dropping, the usual causes are low refrigerant, a stuck valve, or a frost cycle that has failed. A visit tells normal operation apart from a real fault. You hear the fee when you call.
Why is my heat pump covered in ice?
A light coat of frost is normal, and the system melts it off on its own from time to time. Thick ice over the coil, or ice that never melts, is not normal. It usually means a failed frost sensor or board, or low refrigerant. Switch to emergency heat and book a visit before the ice damages the fan or the coil.
Is steam coming off my heat pump normal?
It is. Every so often the outdoor coil warms up to melt the frost that has gathered on it. That melting frost rises as a cloud of steam for a few minutes. It can look alarming and it is completely routine. Steam with loud noises, or melt cycles running one after another for hours, is worth a call.
Why is my auxiliary heat always on?
Auxiliary heat is meant for the coldest hours and for a short stretch after the unit melts its frost off. When it runs without stopping, your heat pump is not making its share of the heat. Usually that means a refrigerant leak, a compressor fault, or a thermostat set up wrong. Those backup coils pull heavy power, so this shows up on the electric bill first.
When should I use emergency heat?
Use emergency heat when the heat pump itself has clearly failed. Locked in ice, making mechanical noise, or tripping breakers. It runs the backup coils on their own and keeps the house warm while it protects the equipment. Think of it as a get-you-through setting, not an everyday one, so book a visit rather than leaving it on all season.
How much does heat pump repair cost?
You hear the diagnostic fee when you call, before the visit is booked. Once the testing is done, your technician writes down the repair price, and nothing goes forward without your approval. What it costs depends on which part failed, so any figure handed to you before the system is tested would be a guess.
Do you repair all heat pump brands?
We do. We work on the common brands installed in Germantown, Gaithersburg, Rockville, Potomac and Olney, including Carrier, Trane, Lennox, Goodman, Rheem, and York, along with ductless equipment. Parts availability changes with the brand and the age. If a part is discontinued or slow to get, you hear that in the written finding rather than after a long wait.
