Does My Heat Pump Have Mold In It?

 

This is a question we get asked all the time. Along with; Do heat pumps really have mold in them?!

Well, the short answer, is .....probably yes, but it does depend on quite a few factors, like:

Conditions Affecting Mold In Heat Pumps....

Air Quality of the area

How often it's used

How often it is switched on and off

How much it is used for cooling

 

 

Whether your heat pump has mould in it does depend on a few factors, but 90% of the heat pumps we see on our first visit contains mold, or the beginning of mold. Most of the other 10% have dirt, dust and other grime. The exceptions are when the heat pump has been cleaned recently or is not used much.

We often take pictures and video's of the mold we see in heat pumps, and if you look around our website you'll see what it looks like!

Some heat pumps begin to breed mold within 12 months but some don't for years, it really depends of a few factors;

 

Air Quality in the home: The quality of the air passing through the heat pump makes a difference to how fast the fins in the coil, and the fan blower wheel get blocked and filled with dust and dirt. Once moisture gets in there, this is a great place for mold to breed. If there's moisture in the air, this can speed up the appearance of mold.

 

Remember: Most of the air in your home passes through your heat pump -

keep it clean to breath safe, fresh air!

How often it's used: If the heat pump is hardly ever used, the chances are it will take a lot longer for mold to appear. However, if you are switching it on and off a lot, the breeding of mold in the heat pump may accelerate. (see below)

 

How often it's switched on and off: Usually, if you are using a heat pump, we recommend setting it to a temperature you like, then leaving it on! When a heat pump is left on, even when it's not cooling or heating, it will run a fan cycle once in a while, or even continuously spin the fan wheel slowly. This is to keep the machine dry, and stop moisture sitting in the heat pump, which can lead to mold breeding. We like to set the heat pump, then leave it running, this is also the most efficient way to run a heat pump! They self adjust and are quite clever machines. If you are going away for a long period, then maybe turn it off, but otherwise, let it do its thing!

 

How much it is used for cooling: When the heat pump is in cooling mode, condensation is produced and can sit in the fan blower wheel and heat pump coil. Whilst the machine is running, the fan tries to evaporate this moisture to keep it dry. But when the machine is off, or between cycles, the moisture is a perfect environment for mold. If you use your heat pump for cooling, you may get mold slightly faster and need your heat pump cleaned a little more often. Heat pumps are great for cooling, you just may need to check it a little more often if you use it a lot for cooling.

Heat pumps are a great  way to heat and cool your home, but like everything else, they will need a clean once in a while. And whatever you have been told, they need a regular deep clean to keep them running efficiently and to prevent mold breeding. Some happen quicker than others, but they all need cleaning.
