If you are constantly getting a rotten or musky smell from the ducts and vents of the HVAC in your house, or you get this smell as and when you put on the unit, then you surely have a big problem of mold infestation inside the HVAC ducts. The air ducts are a passage to cold and hot air. And in the process of allowing in cold air, the temperature changes inside the ducts do initiate lots of condensation and formation of water drops. If you are staying in a generally hot and humid place, then the drops will not always evaporate and clean off. Rather they will form a hot and humid place in the inside of the ducts and will make for the perfect breeding ground for molds.
Keeping the ducts clean is necessary
Before you know how to remove mold in air ducts, you must know the prevention. That’s because if you can prevent any such infestation, then you will never need to worry. However, if you have recently got your HVAC ducts cleaned of an infestation, or are planning to get this done, then also you must know how to prevent the further future growth of molds.
How to keep the ducts clean from mold growth
To understand the process of maintaining mold free HVAC systems, you will have to understand why molds grow here. Molds grow in the perfectly warm and moist environment of the HVAC air ducts when the spores are brought to the place by air or dust or pollens etc. This means if the ducts are maintained dry, then even if the temperatures fluctuate, the mold spores won’t be able to germinate. That’s why the trick is in keeping the air ducts dry.
How to keep the air ducts in an HVAC dry and mold free
Air ducts in an HVAC can be maintained dry and mold-free by following some of these simple steps:
- If needed the HVAC system filters must be changed.
- Condensation of air in the ducts must be minimized, and this can be done by insulating the ducts.
- Mold colonies often develop inside the drip pas of the ACs. Hence the drip pans must be cleaned often and at regular intervals.
- If there are leaks, then air may condense around those points. Hence, leaks must be sealed. Sealing, however, is best handled by HVAC mold cleaning professionals and should be left to them ideally.
- Dehumidifiers reduce humidity in the air. Hence you may use one near the areas prone to humidity.
Concluding notes
Your target must be to keep the overall humidity in the air in the house low so that any water condensing in the HVAC system can dry up, and the ducts stay dry and clean. Also, you must check for all signs of fresh air receipt within the house, and any problem you feel with the nose or senses must make you call for the professionals to do a service check and ensure things are okay.
