Though heat pumps require less maintenance than central HVAC systems, they still need to be maintained at least twice a year to keep them running efficiently.
Our team at Super Heat & Air explains how by staying on top of heat pump tune-ups, you could potentially avoid the following problems!
Heat Pump Problem #1: Reversing Valve Malfunction or Failure
The reversing valve on your heat pump is used to switch the system back and forth between heating and cooling modes. The valve itself is a 4-way connector that is found inside the refrigerant line of the system.
Inside the valve is a sliver that moves between two positions, each of which changes the heat pump to heating or air conditioning mode. This slide is controlled by a solenoid which is an electromagnet that pulls the slide back and forth.
If the reversing valve malfunctions or fails, your heat pump can get stuck in one mode or the other. If this happens, it could be that the slide is stuck, or the solenoid has lost its charge. If the slide is stuck, you will need to call an HVAC pro from Super Heat & Air to open the valve and reset it. If the solenoid has lost its charge, it requires a replacement.
Heat Pump Problem #2: Refrigerant Leaks
There is a common misconception that refrigerant is something that depletes, like gas in a car, and has to be replaced every now and then. If you are losing refrigerant, then it means that you have a refrigerant leak. Refrigerant leaks are not a good thing for any HVAC system so you should get this fixed ASAP.
Just like a conventional air conditioner, heat pumps depend on a set amount of refrigerant to heat and cool your home. When refrigerant leaks and the level drops too low, the output capacity of the heat pump will drop until it breaks down.
If you notice any fluid dripping from your heat pump, call our pros at Super Heat & Air for repairs ASAP.
Heat Pump Problem #3: Heat Pump Constantly Runs in Moderate Weather
Because your heat pump relies on heating energy from the outdoor air, it can be normal for a unit to run all the time when it is very cold or very hot outside. But if the temperature outside is moderate, and the unit is still running constantly, it is time to do some troubleshooting!
- Check your thermostat: Is the heat pump set to the wrong mode? If so, change it to the correct setting and see if that fixes the problem.
- System tune-up: It is not an easy fix like the thermostat, your heat pump may need a tune-up/ Routine maintenance is important to keep the unit running efficiently. If the coils are extremely dirty, your system will have trouble keeping up and will run constantly.
- Clean/Replace the air filter: A dirty or clogged air filter can cause the heat pump system to work harder than it needs to and can lead to failure.
If the unit has been serviced recently and is still running constantly, there may be a deeper issue such as:
- Frozen coils
- Malfunctioning reversing valve
- Low refrigerant
- Compressor issue
For these more serious issues, it is best to contact a professional like our team at Super Heat & Air for an inspection and repairs.
The Importance of Heat Pump Maintenance
