Unlike a clogged air filter that happens quite commonly in many HVAC systems, a wet air filter can be a cause of concern for homeowners and could be a sign that something within your HVAC system needs to be fixed.
One likely cause of a wet filter in an HVAC system is a condensation leak. This happens when debris, dust, and dirt clog the drain line. When this happens, the moisture that has liquidised backs up in the drip pan since its normal route is blocked. This then leads to water overflowing and soaking the air filter.
Another reason could be old age of your HVAC system which is liked to a damaged drain pan. In this case, the pan needs to be replaced. It could also be caused by a dirty air filter that causes a blocked airflow which then causes the evaporator coil to freeze and melt. When the melted water is too much for the drain pan, it could cause a wet filter in your HVAC system.
There are many potential causes and the best way to find out why is to hire WeAreChoice.co.uk, an air conditioning company in Surrey, to check your unit.
Humidity is one reason for a wet air filter. What happens is that the moist and warm air loses its latent heat, some condensate drips from the coils and then into a drip pan located underneath. In most cases, the condensate drains out of the pan by passing through a drain line, eventually heading to your sewer system. But sometimes, when the drain line gets clogged with dirt or other sediment or debris, the condensate remains in the drip and eventually overflows… and some water could get into your air filter.
It’s important to solve this issue right away because when you allow your air filter to remain wet, it can interrupt air flow and there’s high chance of mold and mildew forming and you wouldn’t want that. Fix the leak right away and check if there’s any obstruction or clogging, or any other issues in the drip pan because this is often the root cause of the problem.
The problem can be avoided early on if you’ve had professionals install your air filters or if you regularly check your HVAC systems. If time comes that your filters will need replacing, visit MervFilters.com.
