Common Heat Pump Issues to Avoid

With rising utility costs and increasing environmental awareness, it’s no surprise that more people are switching to energy-efficient appliances. These alternatives work like traditional ones, but use up less electrical power. Not only will this reduce your carbon footprint, but you’ll cut down on your bills, too.

A good example is the heat pump. It uses electricity to collect and transfer hot air from outdoors into your home, keeping you comfortable in chilly weather. Since it only moves warm air without artificially generating it, it evenly distributes heat around an enclosed space at a much lower cost than its traditional counterparts. It’s a practical alternative to a standard thermostat or radiator.

But, it’s not impervious to mechanical issues. Here are some of the most common problems that can affect your system.

It Doesn’t Turn On

There are plenty of causes behind a heat pump that won’t start. The thermostat might’ve been set to the wrong time or calibrated incorrectly, keeping the system from working properly. The problem may also lie in the wiring, which disrupts communication between the component and the device.

If you switch it on and hear a faint clicking noise, then it might mean the starter capacitor is broken. This prevents it from sending a charge that activates the motors. In other cases, the root cause is a tripped breaker or an electrical failure. For these instances, you’ll need to call for a heating, ventilation, and air conditioning (HVAC) repair service.

It’s Not Releasing Much Heat

If the unit starts but doesn’t blow out warm air, there may be something clogging it up. The usual culprits are leaves and other debris blocking the pump’s entryway and restricting airflow. To resolve or avoid this issue, clean it regularly, and clear the surrounding area.

But, if you don’t see any dirt outside the device, then check the filter. It catches all dust so they won’t circulate indoors. Eventually, these airborne particles may build up, blocking the flow. This can be fixed by thoroughly cleaning the part or swapping it with a new one.

It’s also a good idea to check the amount of refrigerant left in the unit. Leaks are hard to detect, so if the system is struggling to do its job, it can indicate low solution levels.

It Blows Cold Air

In case a system makes a place chillier instead of warmer, set the thermostat to emergency heat, which is usually at least 5 degrees above room temperature. If it releases warm air, then the problem lies in the outside unit. Its outdoor coil may be covered in frost or ice, pointing to a damaged control module or defroster timer. This can also be caused by airflow blocked by grass, weeds, and other kinds of debris.

If setting it to emergency heat doesn’t work, then the thermostat or air handler might be broken.

It Isn’t Cycling Properly

When a unit switches on and off too often, it’s a sign of overheating. This is typically caused by a clogged filter or damaged blower, which can be fixed easily. Simply have these parts cleaned or replaced by a professional, and the appliance will run smoothly again.

Another possible reason is that the thermostat needs adjusting or its batteries need replacing.

It’s Making Too Much Noise

Rattling noises are most likely caused by loose screws and bolts. Check and secure them periodically. But, if you hear grinding and squealing sounds, turn off the appliance and get in touch with an HVAC expert. They’ll inspect the unit for more serious issues, like worn-out motor bearings.
