Heat Pump Troubleshooting and Repair in Northampton

Heat pumps keep your home comfy all year, but when they stop working you can feel the heat—or cold—fast. Most issues are simple enough to spot, and fixing them early can save a costly call‑out. Below you'll find the most common reasons a heat pump won’t cool, quick checks you can do yourself, and when it’s time to call a professional.

Why Is My Heat Pump Running but Not Cooling?

First, make sure the thermostat is set to cooling and the fan is on “auto.” A wrong setting is the easiest mistake to miss. Next, look at the outdoor unit. If the fan isn’t spinning, the motor could be jammed, the capacitor dead, or the coil covered in debris. A dirty coil blocks airflow, making the refrigerant stay warm instead of cold.

Another frequent culprit is low refrigerant. Leaks don’t happen overnight, but if the system has been low for a while you’ll notice reduced cooling performance and ice forming on the coils. Checking for ice is a quick visual test—if you see frost on the indoor coil, turn the system off and let it melt before you investigate further.

Quick DIY Checks Before Calling a Pro

1. Reset the system. Turn the breaker off for a minute, then back on. This can clear minor electronics glitches.

2. Clean the outdoor unit. Remove leaves, grass, or dirt that might be clogging the fan. A garden hose on a gentle setting works fine—just avoid high pressure that could bend fins.

3. Replace the air filter. A clogged filter reduces airflow and makes the compressor work harder. Swap it out every 1‑3 months depending on usage.

If after these steps the heat pump still runs without producing cold air, it’s likely a refrigerant issue, a faulty compressor, or a broken fan motor. These problems need a licensed technician because handling refrigerant requires certification.
