When a Heat Pump Fails, Three Things Could Be Happening
Most heat pump problems in Durham fall into one of three categories.
The Heat Pump Will Not Switch Modes Correctly
This is when the heat pump cannot switch cleanly between heating and cooling. It points to problems with the reversing valve, control board, or thermostat wiring. Signs you might see include:
- Cold air blows when you have it set to heat
- Warm air blows when you have it set to cool
- The system gets stuck in defrost and will not come out
- Loud hissing right after the system changes mode
- The outdoor unit runs, but the indoor temperature does not change
- The thermostat shows the wrong mode
The System Switches but Does Not Move Heat Well
For this one, the reversing valve works, but something else is keeping heat from moving between inside the house and outside. Most often, it is the refrigerant, the coils, or the airflow. Signs you might see:
- Weak airflow at the vents or mini-split heads
- The unit runs for hours, but the room never gets to the set temperature
- Ice on the outdoor coil during heating, or on the indoor coil during cooling
- A hissing sound near the refrigerant lines
- Higher electric bills with no change in usage
- The outdoor unit runs, but the air coming out feels lukewarm
The Unit Is Locked Out by a Protection Circuit
It means the control board has shut down the system to protect a component from damage. Often points to a failing capacitor, contactor, sensor, or compressor. Signs you might see:
- The system tries to start, clicks, and shuts down
- A loud hum from the outdoor unit with no fan motion
- The breaker trips when the system tries to run
- Error codes that come right back after a reset
- The outdoor fan runs, but the compressor does not
- A burning or electrical smell from the unit
Local Problems That Damage Heat Pumps
First, Durham winters are tough on heat pumps. Average January lows sit near 22 degrees, and the town gets about 17 inches of snow a year. Therefore, snow drifts pile up around outdoor units and ice forms on coils. Wind blowing across an open lot can also dump leaves into the fan housing.
Second, older Durham homes add their own pressure. Many homes near the Main Street Historic District date back to the 1700s and 1800s. Plaster walls, balloon framing, and limited insulation make these homes hard to heat. That is why it is important to size your heat pump correctly.
Third, summer brings humid days in the 80s and the occasional thunderstorm. Lightning and grid surges can also damage control boards.
Brand-Specific Error Codes Often Seen in 06422
Modern heat pumps flash an error code when something is wrong. Tell us the code when you call so we can bring the right parts.
Our techs do not randomly swap parts. We read the code, test what it points to, and fix that one thing.
Here are the most common ones we see in Durham homes.
- Mitsubishi P1: A failed intake temperature sensor in the indoor head. The system cannot read the room temperature correctly. We replace the sensor.
- Mitsubishi U4: A communication fault between the indoor and outdoor units. Usually, it’s a wiring issue or a damaged control board.
- Mitsubishi P6: Compressor protection lockout from a frozen or overheated coil. Often caused by low refrigerant or a dirty filter.
- Mitsubishi E6: A signal error between the indoor unit and outdoor unit. We check the connections and the boards.
- Fujitsu E:EE: A general communication or system error on Halcyon systems. Requires reading the secondary code on the indoor board.
- Daikin U4: A transmission fault between the indoor and outdoor units. Often from wiring or a failed PCB.
- LG CH error codes: A series of communication and sensor faults. The number after CH tells us which sensor or board is failing.
What to Try Before You Call Us
Some heat pump problems have a simple fix you can try in four minutes. Run through this checklist first. If the issue persists, give us a call at (860) 339-6001.
- Check the thermostat. Make sure it is set to “Heat” or “Cool” and not “Off” or “Em Heat.” Bump the set temperature up or down a few degrees to see if the system responds.
- Check the filter. A clogged filter mimics six different failure modes. If you cannot remember when you last changed it, change it now.
- Clear the outdoor unit. Brush off snow, ice, and leaves. Keep at least two feet of clearance on all sides.
- Check the breaker. If it tripped, you can reset it once. If it trips again right away, stop and call us.
- Write down any error codes on the indoor head, the thermostat, or the outdoor unit before you call.
In all you do, do not open electrical panels and do not add refrigerant from a hardware-store can. Both are dangerous and often illegal.
Emergency Same-Day Heat Pump Repair
Heat pumps tend to fail at the worst possible moment. A 10-degree morning when the system will not start or a muggy afternoon when the indoor coil is iced over.
But don’t worry. We answer calls Monday through Saturday, around the clock, so you can reach a real person when it matters.
For true heat pump emergencies, call us at any time. If water is pouring from the indoor air handler or you get burning smells, we will walk you through a safe shutdown over the phone. And, we will dispatch a team as soon as possible.
If your heat pump is running but acting strange, you can wait until morning. Just keep an eye on it and turn it off if anything gets worse.
Call (860) 339-6001, and we will sort out the next step with you.

FAQs
Is Durham, CT, rural?
Durham is a small, semi-rural town. It sits in central Connecticut, about ten miles south of Hartford.
Is Durham, Connecticut, a good place to live?
Yes. Durham has easy access to Middletown, New Haven, and Hartford. The town is known for its Main Street Historic District, the Durham Fair, and a tight-knit community.
What is the cost of repairing a heat pump in Durham?
Most heat pump repairs in Durham range from $150 to $800. A capacitor swap runs $150 to $400. A refrigerant recharge runs $200 to $1,500. A compressor replacement can run $1,000 to over $2,500.
How do you know if a heat pump compressor is going bad?
Common signs are a loud hum at startup with no fan motion, hard starts, the system tripping the breaker, and weak heating or cooling. Talk to our licensed tech to confirm. Call (860) 339-6001.
What is the 30-minute heating rule?
If your auxiliary heat stays on for more than 30 minutes at a time, your heat pump cannot keep up with the load. That usually means a refrigerant issue, a dirty coil, a sensor fault, or undersized equipment. Call a tech to check it.
Why is my electric bill so high with a heat pump?
The top reasons are auxiliary heat running too often, low refrigerant, a dirty filter, or a stuck reversing valve. A failing defrost cycle also quickly drives up bills. A tune-up usually finds the cause in one visit.
How to tell if a heat pump is overcharged?
Signs include high pressure on the discharge line, the system tripping on high-pressure protection, frost forming on the suction line in cooling mode, and weaker-than-usual cooling. Only a licensed tech can confirm an overcharge.
Is it worth replacing a compressor on a heat pump?
It depends on age. If the system is under 10 years old and otherwise in good condition, replacing the compressor makes sense. If it is over 12 years old, replacing the entire unit may be the better choice.
My system is running R-410A. Is that still serviceable, or am I being pushed to replace it?
R-410A systems are still fully serviceable. The phase-out only affects new equipment. We still repair, recharge, and maintain R-410A systems. Replacement is your call, not the law.
