4 Troublesome Heat Pump Problems And Their Solutions

Almost half of your energy bill pays for heating and cooling your home. Finding the most efficient way to keep your house comfy can keep your wallet fatter and is part of the recent popularity of heat pumps.

But better efficiency isn’t a guard against heat pump failure. Just like with a conventional indoor heating or AC system, your heat pump can develop issues that give you lukewarm air in the summer or cold air in the winter.

Let’s look at the most common heat pump problems and what can be done about them. Keep reading to learn more.

1. Doesn’t Run

If your heat pump isn’t even turning on, there are a few possible causes. First, check that your thermostat is programmed correctly and communicating with the heat pump

Next, make sure you don’t have a tripped breaker that has caused a power loss or the power switch has been turned off. If you’re hearing a faint clicking noise inside the heat pump, you may have a broken starter capacitor.

2. Doesn’t Heat or Cool

If you aren’t getting any hot air through the system, it could be that something is blocking the airflow to the unit. This could be snow, ice, leaves, or other debris outside or even closed vent covers inside. The flow could also be blocked by a dirty air filter, keeping air from getting to the compressor, which is what heats the air.

Conversely, if the pump runs but isn’t cooling, there could be a problem with the reversing valve that switches the pump from heating to AC. There could also be dirty components blocking airflow, or your refrigerant levels might be too low.

3. Doesn’t Blow Air

If you can hear the unit running, but no air is coming out, you may have a broken belt in the blower.

While heat pumps can heat a house even in Alaska, harsh weather conditions can cause the heat pump to freeze or ice over. This severely restricts the airflow causing your unit to struggle and little to no air to blow into the house. If the defrost cycle hasn’t come on, switch the pump off until the condenser unit can defrost.

4. Doesn’t Cycle Correctly

Your system should go through on and off cycles throughout the day. But if the temperatures start to hit the extremes, you might notice the pump seems like it’s running all the time. If that happens when the temperatures are less extreme, you could have an issue with a leaking refrigerant or a frozen outdoor unit.

Your thermostat could also be set incorrectly or have a miscalibration issue that causes it to read the temperature inside incorrectly. A broken compressor contactor can also cause the pump to run all the time since it controls how much power goes to the pump.
