The air filter is an essential part of your home's HVAC system, as it prevents dust and other debris from circulating through the system. If the air filter isn't changed regularly, not only will the debris pass through and clog the air conditioning system, but it will also end up circulating around the house. This can lead to a large repair bill in the future, as well as decreased indoor air quality and personal health. Changing air filters regularly can help preserve the life of the system and make it work more efficiently.
Homeowners who ignore filters in their heating and air conditioning systems risk increasing energy costs, damaging expensive equipment, and decreasing indoor air quality and personal health. The danger of not changing the air filter in the house for a long time is that it will eventually cause damage to the oven. This means that excess heat will destroy the entire system. If you have a more efficient filter and you don't change your air conditioning filter often enough, moisture buildup can cause mold to build up in the ducts and cause severe mold infestations.
In addition to damaging your air conditioning system, neglecting changes to air conditioning filters can also cause mold growth on vent covers, ducts, and the interior of the air conditioning controller. In general, most air filter manufacturers and HVAC companies recommend changing the air filter every 90 days or 3 months. However, once you start to notice that the HVAC doesn't cool the house as it should, you may need to replace the filters. Remember that replacing air filters costs less than $50, so don't let delay and neglect cost you thousands of dollars.
If you've forgotten to change your air conditioning filter for some time, it's very likely that a lot of dust will build up inside the duct network. The mold that grows on the air conditioning controller, ducts and vent covers is probably the biggest potential health hazard by not changing air conditioning filters frequently. And if the air conditioning system doesn't seem to have been properly maintained, such as signs of leaks or dirty filters (and coils) in the past, that can also have a big impact on the buyer's attitude. Probably the biggest danger of not changing your oven's air conditioning filter is that it can damage your HVAC system and reduce its life expectancy. The only type of filters that capture allergens and spores are HEPA, or high-energy particulate air filters. This is a clear indication that the air filters are clogged and should be replaced as soon as possible.
Filters with higher MERV values trap small particles more effectively than filters with lower MERV scores. If you've never changed your air conditioning filter before, it's best to have an HVAC technician do it for you. Not cleaning or changing your AC filter can cause quite a lot of problems, but many people don't incorporate it into their regular routine.
