Hence, before you call that technician who might cost you hundreds, if not thousands, of dollars to fix your heat pump, you might find it wise to fix it yourself. Or have enough knowledge to help you evaluate how much a professional will set you back to fix them as you assess the extent of the problem.
What You Need to Know About Heat Pumps.
Common sense dictates that one understands something in its entirety before trying to fix any problems it has. Right? After all, you must know how your car works before you can determine the kind of problems it has. Hence, we will delve into information on heat pumps so that you can clearly understand how to spot their problems when they occur.
First, heat pumps were designed to warm and cool houses; in the summer, you might need to lower your home’s temperature to certain levels that make it comfortable, while in the winter, you usually want to increase the temperature, ensuring you do not freeze.
Heat pumps come in various types, but there are three common types that you are likely to find in the nearest warehouse: water-source heat pump, air source, which is the most popular, and ground-source or geothermal.

Working Mechanisms of Heat Pumps.
Heat pumps typically transfer heat between outside and inside environments at your home. The appliance is usually installed outside of your house. Hence, depending on the temperatures outside and inside the house, one sets it to either draw heat out of the indoor air and cool the home or heat from outside and transfer it inside during the colder months.
To accomplish these objectives, the heat pump comprises various components, which I will discuss next. It is vital to understand these components since troubleshooting your heat pump’s problems requires you to identify them as you check their efficiency, effectiveness, or whether they function well.
A heat pump has a compressor that maintains the flow of its refrigerant. It increases the temperature when air is compressed into a gas. This component is essential for generating, maintaining, and transferring heat.
The heat pump also has a condenser, which has a compressor, condenser coil, and reversing valve. This component pushes the refrigerant via the condenser’s coil, allowing the metal fins and the fan to transfer heat from the indoors to the outdoors, ensuring your house’s temperatures drop.
The heat pump also has an evaporator. This component exchanges heat using convective and conductive heat transfer. During heating, the evaporator coil removes heat from the refrigerant and returns it to the house. In contrast, heat is transferred from the air to the refrigerant in the cooling process, causing it to evaporate and trap in the humidity.
Finally, the heat pump has an expansion valve. This component is located between the condenser and the evaporator. It is used to control or regulate the flow of the refrigerant from low to high pressure. The refrigerant evaporates at a higher rate when the valve reduces pressure. This action aids the unit in regulating the heat from the refrigerant to control the temperature.
10 Most Common Heat Pump Issues.
Many issues can be attributed to your heat pump not working. Some may be minor, while others might require assistance or consultation with a professional. In this section, we evaluate five reasons why your heat pump may not be working so that you can determine whether you can fix it or replace the entire unit.
- The Heat Pump Does Not Turn on
Imagine walking into your house and finding that the heat pump does not turn on. You panic! But you can always check what the problem is. Usually, a power outage or a power surge could lead to a circuit breaker trip. In other instances, your thermostat has the wrong settings.
For example, if the thermostat has the wrong settings, mode, or temperature, it may fall short of the criteria allowing its activation. Sometimes, the thermostat might not work if it is not connected correctly. Other times, a shortage in the electricity flow could prevent proper communication with the system.
However, one could consider replacing the heat pump if the reversing valve has malfunctioned or there is a faulty start capacitor.
- Heat Pump is Not Cooling or Heating Efficiently.
When your heat pump is not cooling or heating efficiently or effectively, there may be a problem in the ductwork where air is escaping. In other cases, the unit may be too small to maintain optimal temperature based on the size of your home. Thus, to solve this problem, it would be advisable to upgrade the heat pump’s components.
In most cases, one may find fixing or troubleshooting a heat pump difficult. Here, one must engage a technical professional, as this could damage the heat pump or lead to injuries.
- Strange Smells or Noises From the Heat Pump?
If you hear or smell strange noises or smells from your heat pump and cannot identify the problem right away, you must call a technician immediately! This issue could mean that your refrigerant is leaking, mainly if it is producing a hissing sound.
If you hear a banging or rattling, it could mean that one of the heat pump’s components is broken or a foreign object is preventing the hat pump’s fan blades from rotating smoothly. In case you hear a thumping sound, this could mean that the motor is failing.
In case of strange smells, one must consider that a different issue is taking place. For instance, if the heat pump smells musty, it might indicate a moisture problem, causing mold to grow within the component. If there is a burning smell, it could signify that the heating element has accumulated dust.
On the other hand, if there is an electrical burning smell, you must consider that there is an overheating component or damaged wiring.
- Low Refrigerant Levels.
The unit might develop significant issues when the heat pump’s refrigerant leaks. Thus, with the level dropping, you might see ice building or collecting on the evaporator coil. This leads to more severe performance issues.
- Dirty Air Filter.
Cleaning the heat pump’s air filter is very important. If you take long periods without doing so, you will see your heat pump malfunctioning. When the issue occurs for a long time, it causes severe blockages that could strain the heat pump’s components or even lead to higher power usage, translating to more expensive electricity bills.
