Most days, you probably don’t think twice about your heat pump. It just does its thing — keeping your house cool in the summer and warm in the winter. But when something’s off? You feel it fast.
Heat pumps are great systems — they’re efficient, reliable, and work year-round. But like any hardworking equipment, they can run into issues. The good news? A lot of those issues have simple solutions. Let’s walk through the five most common heat pump problems and how to fix them.
1. The Heat Pump Isn’t Turning On
This is one of those moments where silence is not golden. You adjust the thermostat, expecting a warm whoosh of air, but you get a whole lot of nothing instead. Here are a few things to check before you start shopping for extra fans or space heaters:
- Circuit Breaker: A flipped breaker is a common culprit and easy to overlook.
- Fuse or Switch: Double-check the power switch on the unit, and if your system has a fuse, inspect that, too.
- Capacitor or Contactor Issues: If there’s clicking but no action, internal components like the starter capacitor might be worn out.
Still nothing? You’re probably looking at a more technical issue that needs professional help. That’s what we’re here for. Our crew handles heat pump repair in Midland, MI, with care, accuracy, and a deep understanding of how your system works.
2. The Heat Pump Keeps Running Non-Stop
A system that won’t quit can be just as problematic as one that won’t start. Not only does it drive up your energy bill, but it also wears your system down fast.
Here are a few common heat pump problems behind this:
- Clogged Air Filters: Dirty filters restrict airflow, making the system work harder than it should.
- Undersized or Oversized Units: If the unit wasn’t sized right for your home, it might struggle to maintain temperature efficiently.
- Thermostat Trouble: If your thermostat isn’t reading temperatures correctly, it may cause the system to keep running.
Regularly scheduling heat pump maintenance in Midland, MI, with All Seasons Heating & Cooling can help catch these issues early and keep your system humming along properly.
3. It’s Blowing Cold Air When It Shouldn’t Be
Expecting warmth and getting a chilly breeze instead? That’s a sign something’s off. Let’s talk about what might be going wrong:
- Reversing Valve Malfunction: This part switches the system between heating and cooling. If it fails, you might get cold air when you need heat.
- Low Refrigerant Levels: If refrigerant is leaking, heat transfer becomes inefficient.
- System in Defrost Mode: If the outdoor unit is iced up, the system might be in defrost mode temporarily.
If your living room is starting to feel like a walk-in freezer, it’s time for some good old-fashioned heat pump troubleshooting. Let our technicians pinpoint the issue and get your home cozy again.
4. Ice Is Building Up on the Outdoor Unit
Some frost is normal, but if your heat pump looks like it belongs in a snow globe, you have a problem. Here’s what could be causing it:
- Restricted Airflow: Snow, ice, or leaves blocking the unit can disrupt heat exchange.
- Faulty Defrost Controls: If the defrost cycle isn’t kicking in properly, ice will keep piling up.
- Refrigerant Leak: Without the right refrigerant level, coils can freeze over.
A frozen-over system leads to bigger issues, including reduced efficiency and potential damage. Regular upkeep and fast service calls are your best defense.
5. It’s Making Strange Noises
Your heat pump shouldn’t sound like a rock tumbler or a haunted house. If you hear grinding, squealing, or rattling, something’s not right:
- Loose Panels or Parts: Vibrating parts can cause all kinds of racket.
- Worn-Out Compressor or Motor Bearings: These are more serious issues and need a professional’s attention.
- Debris in the Outdoor Unit: Sticks, leaves, or even a lost baseball can make their way inside and cause all sorts of clatter.
In any case, don’t ignore weird noises. They rarely go away on their own and often point to bigger issues on the horizon.
Tips for Heat Pump Troubleshooting
Before calling in help, you can do a little DIY heat pump troubleshooting to save time and money:
- Check your thermostat.
- Reset the circuit breaker.
- Clear away debris from the outdoor unit.

Knowing how to troubleshoot a heat pump can save you some stress and keep you ahead of bigger repairs.
