Heat Pump Repair: Simple Steps to Get Your System Working Again

Heat pumps keep your home cozy in winter and cool in summer, but when they act up, the whole house feels off. The good news is many problems have easy fixes you can try before dialing a technician.

Why Your Heat Pump Might Not Be Cooling

The most common complaint is a heat pump that runs but never produces cold air. Usually the issue is one of three things: low refrigerant, a dirty filter, or a faulty thermostat.

First, check the air filter. A clogged filter restricts airflow, forcing the system to work harder and often stalling the cooling cycle. Remove the filter, give it a good tap, or replace it if it looks dirty.

Next, look at the outdoor unit. If ice has formed on the coil, the pump can’t pull heat from the air. Turn the system off for 30 minutes, let the ice melt, and clear any debris around the unit. Trim back shrubs and remove leaves that might block airflow.

If the filter’s clean and the unit is ice‑free, the problem may be low refrigerant. You’ll notice a hissing sound or visible oil spots near the connections. This isn’t a DIY job – call a licensed pro to recharge the system safely.

When to Call a Professional

Some issues are best left to experts. A broken compressor, dead fan motor, or electrical fault can cause the pump to shut down completely. If you hear the system start then stop suddenly, or if the indoor blower runs but the outdoor fan is silent, it’s time to schedule a visit.

Professional technicians can also run a full diagnostic, check pressure levels, and clean the coils inside the indoor coil. Regular maintenance, like an annual service, catches these problems early and extends the life of your heat pump.

While waiting for a technician, keep the thermostat set to “auto” instead of “on” to avoid overheating the system. Turn off any supplemental heaters that might mask the real issue.

In most cases, a quick filter change, clearing debris, and a short defrost cycle will bring your heat pump back to life. For anything beyond that, trust a certified repair service – they have the tools, parts, and warranty protection to get the job done right.

Remember, routine care is the cheapest way to avoid expensive repairs. Clean the filter every month, keep the outdoor unit clear, and book a yearly service. Your heat pump will thank you with steady comfort all year round.
