Common Heat Pump Problems We Solve
Here are some of the most frequent issues we’re called to repair—and how we help:
- Your Heat Pump Won’t Turn On: If your heat pump won’t start, the problem might be as minor as a thermostat missetting or a tripped breaker, or more complex like electrical component failure. We’ll quickly pinpoint the cause using expert diagnostics and restore power to your system, getting your home comfortable again fast.
- The System Isn’t Heating or Cooling Properly: When your heat pump fails to maintain indoor temperatures, common culprits include low refrigerant, dirty coils, or a faulty reversing valve. These issues reduce efficiency and comfort. Our team will identify the specific problem, restore functionality, and ensure your system delivers consistent heating and cooling year-round.
- Unusual Noises or Vibrations: Strange sounds like rattling, squealing, or grinding usually signal internal issues—such as loose hardware, worn-out bearings, or motor trouble. Ignoring these can lead to major breakdowns. We’ll locate the noise source, perform necessary repairs, and protect your heat pump from further damage or costly complications.
- Frozen Coils or Ice Buildup: Ice accumulation often results from blocked airflow, dirty filters, or refrigerant issues. Left untreated, it can damage the compressor or other components. We’ll carefully remove the ice, restore airflow, and fix the root problem to keep your system running efficiently and prevent future freezing.
- Short Cycling: Short cycling—frequent starting and stopping—wastes energy and strains components. It’s typically caused by dirty air filters, thermostat errors, or electrical faults. We’ll troubleshoot and resolve the issue, helping your system operate more smoothly, extend its lifespan, and reduce energy costs through consistent performance and proper runtime.

Why Heat Pumps Are Ideal—and Why Repairs Shouldn’t Wait
In Arizona, many homeowners choose heat pumps for their ability to handle both cooling and heating in one efficient system. Given Scottsdale’s relatively mild winters and scorching summers, heat pumps offer a great balance of comfort and energy savings.
However, because they operate all year, heat pumps experience more wear and tear than systems that only run seasonally. That makes them more prone to mid-season breakdowns—often during the times you need them most.
Common signs your heat pump may need repair include:
- Uneven temperatures or weak airflow
- Loud or unusual noises during operation
- Higher-than-usual energy bills
- A system that runs constantly or short cycles
- Ice buildup on the outdoor unit
- Failure to switch between heating and cooling modes
Ignoring these signs can lead to more extensive damage, system failure, and higher repair costs. At LJ Refrigeration, we believe early intervention is key—and we make it easy for Scottsdale homeowners to get fast, affordable heat pump repairs they can count on.
