If you have central heating and air conditioning in your home, you might occasionally have issues with heightened moisture in the system. This can eventually lead to mould. It is important that you remove the mould at the first signs of it so those mould spores don't ruin the system and enter the air in your home when the unit is running.
Have the Ducts Cleaned
A lot of the mould in your HVAC system will end up in the ducts. This is bad for the quality of your air, as the air goes through the ducts and out the vents when you have the air conditioner or heater turned on. Avoid potential issues by starting with a professional duct cleaning service. They will likely find traces of mould and remove it for you. If you want to remove it with a DIY system, get rid of the mould debris first by using a vacuum with a long attachment. This can suck up the debris and get rid of mould spores without causing a big mess. Attachments with scrub brushes at the end are also effective at removing mold debris from the ducts.
Clean Out the HVAC Unit
The next thin you should do is clean out your air conditioner and heating unit, including the evaporator coils and drip pans. A lot of mould can build in these parts of any HVAC system, which can grow and cause a lot of problems with the health of your air when turn on the system. Look for signs of standing water around the unit, as this is a sign of a leak. Leaks need to be addressed by a professional, as the water can ultimately lead to more mould growth. Once the inside of the unit is cleaned, look for other signs of repairs that are needed. A wet vacuum will help you remove any excessive amounts of water that is leading to mould growth.
Change the Filters
Whether you have reusable or disposable filters in your HVAC unit, they should be replaced when you have signs of mould or mildew in the unit. These filters often get build-up and debris in order to provide your home with clean air. However, when this debris sits in the filters for too long, it can combine with moisture in the unit and eventually lead to mould. Cleaning the reusable filters may not be enough to remove all traces of mould spores, so it is best to get brand new ones in the unit. After replacing them, remember to keep them cleaned out on a regular basis to help avoid mould in the future.
