Commercial Heat Pump Issues You Should Know About

commercial-heat-pumpCommercial heat pumps are quite common throughout the country, as they help save energy without sacrificing climate control for the building. As you begin to rely on your commercial heat pump more often this winter, though, you’re going to be putting more strain on the system. This will raise the chances of problems developing in the heat pump over time.

You should know how to identify problems with your commercial heat pump, so that you can have it repaired before it suffers too much damage. The following are some of the more common heat pump issues that you should be careful of, and their warning signs.

Refrigerant Leaks

Whether you’re using your system for heating or air conditioning, the heat pump relies on refrigerant to accomplish climate control. The system recycles refrigerant back and forth between liquid and gaseous states to move preexisting heat out of the building. A refrigerant leak will slowly rob the system of output capacity, as the level of available fluid in the heat pump drops. If the leak isn’t patched, the fluid level will eventually drop so low that the system will break down. So, make sure that you call for repairs if you notice the system leaking fluid.

Air Handler Problems

The air handler is the part of the heat pump responsible for circulating air throughout the building while the system is operating. If the heat pump seems to be circulating less air than it normally does, it might be due to the air handler malfunctioning in some way. The most common issue for the air handler is bearing failure. The lubricated bearings are meant to reduce friction on the air handler, but they wear down over time. As the bearings begin to fail, friction on the air handler motor increases and negatively affects its efficiency. If the bearings are not replaced, the air handler motor may eventually overheat and burn out. If you hear a grinding sound coming from the heat pump, it means that the air handler needs to be repaired immediately.

Reversing Valve Issues

The reversing valve is the part of the heat pump that is responsible for changing the direction that refrigerant flows through the system. If a problem develops in the reversing valve, it can easily cripple the system by locking it into either heating or cooling mode. If your commercial heat pump appears to be stuck in cooling mode, it might mean that the slide in the valve is stuck, or that the solenoid has lost its charge. Repairing the valve should restore the system to proper function.

Clogged Air Filter

If the air filter in the heat pump is not cleaned out every three months or so, it may become clogged with dust and other debris. This will prevent the system from getting enough air, and cut down on its output capacity as a result. Make sure you have a professional clean out the filter every few months to keep things flowing smoothly.
