Heat Pump Repair

When your heat pump stops doing its job, it doesn’t take long for discomfort to set in. Maybe the air feels lukewarm when it should be warm. Maybe it’s not cooling your home properly. Maybe your outdoor unit is icing up. Or maybe your system just never seems to shut off. Whatever the symptom, it usually points to a specific mechanical issue — and at BPM Heating, Cooling & Plumbing, we’re trained to find it fast.

We provide expert heat pump repair services across Maryland and Pennsylvania. With same-day availability and fully licensed technicians, we’ll get your home back to comfort without the hassle.

Recognizing the Signs of Heat Pump Trouble

Some heat pump problems come on suddenly. Others build up slowly, costing you efficiency and comfort along the way. Knowing what to watch for can help you catch issues early and avoid expensive breakdowns.

If your heat pump shows any of these signs, it may be time for a professional diagnosis:

  • Blowing cool air in heating mode
  • Running constantly but never reaching the thermostat setting
  • Outdoor unit frozen or covered in ice
  • Unusual sounds like buzzing, hissing, or grinding
  • A noticeable spike in your electric bill

What’s Actually Going Wrong Inside Your Heat Pump?

Behind every symptom is a mechanical cause — and finding the exact one is the difference between a quick fix and wasted time.

For example, a system that blows cold air might have a faulty reversing valve stuck in cooling mode. Ice buildup in winter often points to a malfunctioning defrost control board. And short cycling can trace back to something as small as a burned-out capacitor or as major as refrigerant leakage.

Here are some common parts that tend to fail:

Component Common Issue
Reversing Valve Stuck or shorted, stuck in one mode
Thermostat Miscalibration or communication failure
Defrost Control Board Doesn’t trigger defrost in winter
Capacitor Prevents compressor from starting
Refrigerant Lines Leaks that reduce pressure and cooling ability

These failures aren’t always obvious at first. But once one part begins to malfunction, others often follow — which is why fast diagnosis and repair is so important.

What to Expect When You Call BPM For Heat Pump Repair

When you book a heat pump repair visit with us, you’re not getting guesswork — you’re getting clarity. Here’s what our process typically looks like:

  1. A trained technician arrives promptly and inspects your full system
  2. We explain the problem clearly and offer flat-rate repair pricing
  3. If you approve the work, we get started right away — often with parts on hand
  4. After the repair, we test everything again to make sure your system is running like it should

We believe HVAC service should be straightforward, not stressful. That’s why we focus on communication, speed, and doing the job right the first time.

What Does Heat Pump Repair Cost?

No one likes surprise pricing, especially when your home comfort is on the line. While the exact cost depends on the part and labor involved, most repairs fall into a predictable range.

Here’s a look at typical service costs:

Repair Type Typical Cost Range
Thermostat Replacement $200 – $350
Refrigerant Recharge $350 – $800
Reversing Valve Repair $650 – $1,200
Capacitor Replacement $150 – $250
Full Compressor Repair $1,000+

We’ll give you a full quote before any work begins. And if a repair isn’t worth it, we’ll explain why — and what your replacement options look like instead.

When to Consider Replacement Instead

Every system has a lifespan. If your heat pump is more than 12–15 years old, needs frequent service, or requires a costly repair (like a new compressor), replacing it might make more financial sense.

We’re here to help you weigh the pros and cons. In general, we recommend replacement if:

  • Repair costs exceed 50% of the price of a new system
  • Your system uses outdated refrigerant (like R-22)
  • You’re seeing rising energy bills despite maintenance

Need help comparing brands or SEER ratings? We’ll walk you through your options and can even provide a same-day replacement estimate.

Frequently Asked Questions

Whether you’re dealing with an unexpected breakdown, planning a new installation, or just trying to stay ahead of seasonal maintenance, it’s normal to have a few questions. Below, we’ve answered some of the most common ones our customers ask — to help you feel more confident about your system.

How do I know if my heat pump needs repair?

Heat pump problems aren’t always obvious — at least not at first. Many homeowners first notice subtle symptoms like rooms not reaching the set temperature, the system running longer than usual, or strange sounds from the outdoor unit. But these can be early warning signs of more serious internal issues.

Here are some of the most common signs your heat pump needs repair:

  • Inconsistent temperatures between rooms, even when the thermostat is set correctly
  • Airflow that feels weak or lukewarm, especially during extreme heat or cold
  • System running continuously without cycling off — often a sign of a refrigerant or defrost issue
  • Loud or unusual noises, such as buzzing, rattling, or grinding
  • Ice buildup on the outdoor unit in winter, or moisture pooling around it
  • Unexplained energy bill increases, often caused by reduced system efficiency

If your system isn’t keeping up the way it used to — even if it’s still technically “working” — it’s worth having a technician perform a diagnostic inspection. Small issues can lead to major damage if ignored.

Yes — heat pumps can absolutely be serviced in the winter, and in fact, many of the most urgent issues occur during cold weather. Because your heat pump serves as both your cooling and heating system, winter puts extra strain on components like the reversing valve, defrost board, and auxiliary heat controls.

Common cold-weather problems include:

  • Frozen outdoor coils due to failed defrost cycles
  • Reversing valve stuck in cooling mode, causing the system to blow cold air
  • Burned-out heat strips or faulty relays in dual-fuel setups
  • Compressor strain from low ambient temperatures

Our technicians use cold-weather-rated diagnostic tools and methods to safely access and service systems, even when temperatures drop well below freezing. If your heat pump is blowing cold air or has ice buildup, don’t wait — those are signs it needs professional attention now.

Heat pump systems are complex, but the majority of failures stem from just a few critical components that are prone to wear and tear.

Here are the top causes we see:

  1. Capacitor Failure
    The capacitor stores energy to help the compressor and fan motors start. When it fails, your system might hum but won’t start — or it may shut off prematurely.
  2. Low Refrigerant (Leak or Undersupply)
    A refrigerant leak not only reduces heating and cooling performance, it also strains the compressor. Low refrigerant is one of the leading causes of icing and poor airflow.
  3. Reversing Valve Malfunction
    This part switches your system from heating to cooling. If it sticks or shorts out, your unit may become “stuck” in the wrong mode or stop working altogether.
  4. Defrost Control Board Failure
    In cold weather, your system must defrost the outdoor coil to continue heating. A failed board can allow ice to build up, choking airflow and damaging the fan motor.
  5. Dirty or Clogged Filters/Coils
    Sometimes the problem is simple — reduced airflow due to dirt buildup can overwork the system, trip safeties, and even cause coil freezing.
  6. Thermostat Issues
    If the thermostat isn’t reading properly or loses communication with the heat pump, it may cycle erratically or run the wrong mode.

Each of these issues is fixable, but fast diagnosis is key to preventing cascading failures or system damage.

That depends on a few key factors: the age of your system, the cost of the needed repair, and your long-term goals for energy efficiency and reliability.

Here’s a quick way to think about it:

Factor Repair Recommended Replacement Recommended
System Age Less than 10 years Over 12–15 years
Repair Cost Under $500–700 Over 50% of system value
Frequency of Repairs First or second issue Recurring issues
Energy Efficiency SEER2 14+ and working fine Older SEER <13, high bills
Home Comfort Comfortable, stable temps Still struggles after repair

If your system is relatively new and the issue is isolated (like a capacitor or valve), repairing it is often the right call. But if you’re seeing constant breakdowns, uneven performance, or rising electric bills, investing in a new high-efficiency heat pump may save you money and frustration long-term.
