It is likely that at some point you may experience a heat pump problems. It might not be able to cool or heat efficiently or may not function in any way. Below are some of the most common heat pump issues and ways to fix them. If you need assistance, it is always possible to talk to an HVAC expert to help in maintaining your heat pump.

The Heat Pump Does not turn on

If your heater isn’t working, it’s likely to be due to an electrical problem. The first thing to check is if your heater is receiving electricity.

If the light switch remains turned on, however, the heat pump still not functioning, the issue could lie in your thermostat settings. Check your thermostat has been set correctly in mode. If you’ve replaced the thermostat in recent times, it is also important to verify that it is compatible with the system you have and is connected correctly.

Before making the service call, be sure you look for tripped circuit breakers or a fuse that has blown within the box for panel. Reversing the circuit breaker as well as replacing it may help solve the problem. If the switch goes off once more, there could be an electrical short in the system. In these cases, we suggest calling an experienced professional to resolve the problem.

Thermostat Issues

The thermostat tells your heating pump what temperature to keep. If your thermostat is not powered due to a reason, it will not be able to inform your heat pump on what it should do. In the end, your heating system will not be able to turn on.

If the thermostat’s display isn’t active, it means that it is not running electricity. Replace the batteries, or for units that are hardwired, make sure you check the electrical panel. The circuit breaker might be tripped, or you could have a fuse that is blowing. It is possible to detect a damaged fuse and then replace it yourself. Make sure you turn off the electrical supply before taking out the fuse.

Heating Pump Problems: Not Cooling

If your heater isn’t cooling correctly, you must first look at for thermostat setting. If temperature settings are in order, it could be a problem related to the thermostat wiring. A professional can help you to rewire your thermostat to register the temperature fluctuations efficiently.

You may also check to see if particles block your outdoor unit. Clean , and then check whether the air filters need replacement.

A heat pump may not provide efficient Cooling if refrigerant levels are low. If the system has low charges is an indication of leakage. Talk to an HVAC professional to address the leak and refill the system with the proper refrigerant.

The Heat Pump is not Heating.

If your having heat pump problems where the pump isn’t producing enough heat, first look at your thermostat’s settings. Most likely, it is because the thermostat hasn’t been sending the correct signal out to your outdoor device.

A malfunctioning reversing valve or defrost timer may be the cause if the heating system can’t warm the indoors correctly. A trained professional can assist you in replacing the valve.

A system that is not fully charged with refrigerant can also result in inefficient Heating. It is recommended to top off the heat pump with a proper refrigerant charge. Let an HVAC professional assist you in identifying refrigerant leaks and in topping up the system.

Power Loss

The outdoor and indoor units are equipped with different power switches. First, verify the power switch near the unit in your indoor area, and make sure it’s set to ON. Check the power switch close to the outside unit to determine if it’s switched to ON. Also, examine your electrical panel at home to determine if the circuit breaker is tripped or a fuse has blown.

Heat Pump Makes Noises

In time, your heating system could begin making strange sounds, and it is essential to pay attention to these warning signs to avoid your system from breaking completely. If you are hearing humming sounds coming from your heater, your hardware could be loose. If necessary, tighten the fasteners.

If, however, you start hearing unusual sounds, such as grinding or squealing, then the problem could be more serious, like a malfunctioning motor bearing or a worn-out compressor. If that is the case, shut off the unit right away to avoid further damage. You can also seek assistance from a professional to determine and address the issue.

Dirty Air Filters

To allow a heat pump to operate efficiently, it requires an ongoing supply of clean, fresh air. If your heater’s filtering system has become dirty or blocked, less air will pass through the filter. Consequently, the heat pump will need to be running continuously to maintain the temperature you set.

Cleaning or replacing the air filters will resolve this issue. On average, you need to clean your air filters once every two weeks and then replace them once every 3-4 months.

A simple visual examination is enough to find out if the air filters are filthy. Place them against the light source, and if you’re able to see through them with no obstructions and clear, then you’re good to go. If not, clean your air filters using soapy water and allow them to dry completely before putting them back.

Outdoor Fan Problems

For your outdoor unit, it blows air across the coil, which has refrigerant inside it, which is essential for the process of heat transfer needed to cool or heat your home. If your fan for your outdoor is damaged, there’s only a little airflow. Insufficient airflow could cause the outdoor unit to freeze. Get a professional’s help to examine the motor for your outdoor unit in this instance.
