What Could the Strange Heat Pump Noises in Your Home Mean?

If you have an HVAC unit inside of your home, you already know how wonderful they are. Thanks to the thermostat that’s on your wall, all you have to do is walk over to it and set it to the temperature that you want the rooms inside of your home to be.

But if you were to speak with a professional HVAC technician about all of the components that are inside of your system, you would realize that HVAC units are quite intricate. Take heat pumps, for example. They are the part of the unit that helps to efficiently heat and cool your house all throughout the year. Therefore, you want yours to be working optimally at all times.

So how can you know when your heat pump is not in the best condition? One way is to determine the different kinds of sounds that it has the tendency to make. If you’d like to know what various heat pump noises ultimately mean to the life of your unit, here’s a list that can provide you with the information that you want to know.

Normal Noises

When it comes to your heat pump, it’s actually pretty normal to hear some low-level sounds coming from it. Depending on the type of HVAC unit you have, some sound a bit like an unbalanced load of clothes inside of a washing machine when they start up while others make a bit of a squealing noise. Also, once the unit is shutting down, it might remind you of a backpedaling noise. All of this is considered to be perfectly normal and nothing to worry about.

Fixable Noises

Then there are some noises that will alert you to there being some minor issues with your unit. For instance, if you notice a bit of a vibrating sound whenever the unit cuts on, that could be because some of the screws are loose on the cover panel. It also might be because the belt on the pump is either loose or has slipped off. If this is the case, all of you have to do is remove the cover panel of the unit and either realign or replace the belt. Another relatively fixable noise is a pinging sound that comes from the ducting (in fact, in order to avoid having this type of issue is why many HVAC technicians tend to talk to their customers about the benefits of ductless equipment). To fix this, make a small dent in the metal. That way, the loose spot will not move whenever the unit turns on.

Problematic Noises

There are some noises that are not easy to fix – ones that should alert you to contact an HVAC technician as soon as possible. One of them is if you hear what sounds a lot like a hissing sound. That is usually indicative of a refrigerant leak. Another is if when the compressor comes on, it sounds like popcorn is popping. When this happens, oftentimes it’s because some refrigerant is getting into the compressor. High-pitched screams tend to be the result of the compressor having pressurization problems and metallic banging is a sign that your motor mounts may be loosening up. These are all things that need professional attention.
