If your heat pump isn’t heating, cooling, or making weird noises, you’re not alone. Most homeowners face at least one of these issues each year. Understanding why the problem occurs lets you act fast and avoid costly repairs.
Cold air blowing when you need heat is usually a sign of a frozen outdoor coil. A thin layer of ice builds up when airflow is blocked or the refrigerant level is low. Clear any leaves, dust, or snow from the unit and check the fan for obstructions.
Short‑cycling – the system turning on and off every few minutes – often means a thermostat problem or a clogged filter. When the filter is dirty, the unit works harder, overheats, and shuts down to protect itself.
Loud humming, rattling, or grinding noises point to motor bearings or fan blades that need lubrication or replacement. Ignoring the sound can cause the motor to seize completely.
Water pooling around the indoor unit usually means a drainage issue. The condensate pump may be clogged, or the drain line could be frozen in winter. A simple flush with a garden hose can clear most blockages.
Sudden loss of heat or cool output can be caused by low refrigerant. Leaks are not something you can fix yourself; a professional must locate and repair the leak, then recharge the system.
Error codes flashing on the control board give clues about the fault. Consult the user manual for the code meanings – many are simple sensor resets you can do in a minute.
Start with the basics: turn off the power, remove the filter, and give it a good shake or wash. Let it dry completely before reinstalling.
Inspect the outdoor fan for debris. Use a soft brush to sweep away dirt and a garden hose to rinse the coils. Make sure the fan spins freely; if it’s sluggish, lubricate the motor shaft.
Look at the thermostat settings. Verify it’s on the correct mode (heat, cool, auto) and that the temperature is set a few degrees higher than the room temperature.
Check the circuit breaker. A tripped breaker can make it seem like the whole system is dead. Reset it and see if the unit powers up.
If you hear a clicking sound when the unit tries to start, the capacitor might be failing. Swapping a capacitor is a quick job for a qualified electrician, but most DIYers should call a tech.
When you’ve cleared the obvious issues and the heat pump still misbehaves, it’s time to call in experts. A professional will test refrigerant pressure, inspect electrical connections, and run a full performance check.
Regular maintenance can prevent most of the above problems. Schedule a yearly service, clean the filters monthly, and keep the surrounding area clear. When you need help, Nuneaton Appliance Repair Experts are just a call away – fast, reliable, and locally trusted.
