Heat Pump Repair & Service in Chester County
Is your thermostat stuck on auxiliary heat? We diagnose the underlying problem and restore reliable, efficient comfort to your home.
Restoring Your Comfort with Expert Heat Pump Repair
Is your thermostat stuck on "Auxiliary Heat" while your vents blow lukewarm air, or is your outdoor unit vibrating violently under a solid block of ice? Heat pumps handle both your heating and cooling, which means these complex systems endure double the wear and tear, and ignoring these warning signs will only result in a dead compressor and a massive electric bill. DiBiase Heating and Cooling Company is ready to dispatch a fully stocked truck to properly diagnose and repair your system today.
Warning Signs Your Heat Pump Needs Professional Attention
The Auxiliary Heat Indicator Stays On
Your thermostat constantly displays "Aux" or "Emergency Heat," signaling that your system has lost its primary heating capacity and is relying on expensive electric resistance strips. This usually points to a refrigerant leak, a bad compressor, or a failing outdoor fan motor that forces the system to use backup heat. Because electric resistance heating costs up to three times as much to run, ignoring this means you will pay for the repair cost in wasted electricity within a month.Lukewarm Air Blowing from Vents
The blower is running, but the air coming out of your registers feels cool, drafty, or barely room temperature. This is typically a sign of a stuck reversing valve or a low refrigerant charge preventing the system from transferring heat effectively. A heat pump struggling to move heat will run continuously to satisfy the thermostat, leading to severe wear and tear on your compressor.Heavy Ice Buildup on the Outdoor Unit
While a light frost is normal, a solid block of ice means your system's defrost cycle has failed and the fan blades might start grinding against the buildup. Ice acts as an insulator that prevents the system from absorbing heat from the outside air. If the ice builds up enough to freeze the fan blades in place, the fan motor will burn out and the compressor can suffer fatal liquid slugging.Rapid On-and-Off Cycling
Your system turns on, runs for three to five minutes, shuts off, and then immediately turns back on again without actually conditioning the house. Short cycling in a heat pump usually points to a severe airflow restriction, a failing run capacitor, or a low-pressure safety switch tripping due to a refrigerant leak. Starting up is the hardest part of the cycle for a compressor, and this rapid cycling draws massive amounts of electricity while prematurely killing your equipment.Common Heat Pump Failures We See in the Field
Stuck or Failing Reversing Valve
Because heat pumps provide both heating and cooling, they rely on a brass reversing valve to physically change the direction of the refrigerant flow. Over time, the internal slider can get jammed due to debris, worn-out seals, or a burnt-out solenoid coil, trapping your system in the wrong mode. We test the electrical signal first, and if the valve is mechanically stuck, we recover the refrigerant, braze in a new valve, and recharge the system.Electrical Component Fatigue
Heat pumps run year-round, meaning electrical parts like contactors and capacitors take double the beating of a standard air conditioner or furnace. Pitted contactors and swollen capacitors frequently disrupt the high voltage needed to start your compressor. We swap these failing components out quickly to restore proper voltage before they cause a catastrophic motor failure.Refrigerant Leaks
A heat pump is a sealed system that does not consume refrigerant, so if your levels are low, you have an active leak. These leaks typically develop in the evaporator coil, the outdoor condenser coil, or at brazed joints due to constant vibration and thermal expansion over the years. We use electronic leak detectors to pinpoint the exact source, repair the copper line, pull a deep vacuum, and weigh in the exact factory charge.Poor Building Envelope
Sometimes the heat pump is functioning perfectly, but older, drafty homes leak conditioned air faster than the system can produce it. We look beyond the box in the basement to evaluate your insulation and air sealing. Solving the root cause of your energy loss often fixes the comfort issue without replacing a single mechanical part.What to Expect During Your Heat Pump Service Visit
When you call DiBiase Heating and Cooling Company, our phones are answered to schedule a window that works for your life. Our technician arrives in a fully stocked truck ready to troubleshoot the complex blend of refrigeration, high-voltage electricity, and airflow that makes up your heat pump. We never just guess at the problem or throw parts at a symptom.
We start by interviewing you about what you have noticed, then hook up our gauges to check refrigerant pressures, test electrical draws with a multimeter, and measure the temperature split across your coils. Once we pinpoint the exact failure, we sit down with you and provide a flat-rate price for the repair. You approve the cost before any wrenches turn, ensuring there are no surprises on your final bill.
After executing the repair, we test your system in both heating and cooling modes to verify the reversing valve and defrost cycle are functioning perfectly. Our goal is to fix the underlying mechanical issue and restore your home's comfort for the long haul. We clean up our workspace and leave your property exactly as we found it.
Benefits of Installing a Heat Pump
There are many benefits to installing a heat pump in a house. Some of the top advantages they provide are:
- Energy-efficiency. Because these systems use a renewable energy source, they are more energy-efficient than traditional heating systems. This can result in lower utility bills.
- Government incentives. Getting a unit can qualify you for government incentives for installing a renewable heat unit. You could also be eligible for a tax rebate.
- Improved indoor air quality. This system doesn’t create smoke or add fumes to the air, resulting in better air quality in your home compared to using a forced-air unit.
- Increased safety. These units can be safer than heaters or furnaces.
- More climate control. These systems allow you to have maximum control over the interior climate of your house.

- Cleaning the condenser to remove debris and dirt.
- Checking the coils to ensure they work correctly.
- Replace the air filters regularly, about every 1 to 3 months.
- Check the ductwork for leaks or defects.
- Clean the fans and ensure they are working properly.
- Check the refrigerant levels.
- Examine the thermostat settings to ensure it heats to the desired temperature.
- Inspect the electrical components for loose connections, frayed wires, and other signs of wear and tear.
- Schedule yearly maintenance and heat pump tune-ups with a professional.
