HVAC Filters and Why You Should Change Them

The purpose of the filter in your heating and cooling system is more than just cleaning the air so we breathe better. Its purpose is also to keep the coil (much like a car radiator) clean so the unit works to its full potential and highest efficiency.

Dirty filters clogged filters like the one in the picture. Makes your system work longer and harder. Dirty filters reduce life expectancy, increase heating bills and may cause a fire.

This filter is so dirty the fan motor sucked the filter in against the fan cage and fan blades, which can damage the fan and potentially cause a fire. This could have been a disaster. Fortunately it wasn’t. A good cleaning, a service call, new filter, good to go..

If you think you have no worries because you have a gas heating unit think again. If you have central air (this is a gas unit with central air) then you have the same concern. A low grade filter cost less than $1.00, more expensive ones like HEPA filters can costs upwards of $5.00 each, but that is still only $60.00 a year. My family is worth it. Is yours?

Change disposable filters every thirty days, and clean washable ones at least every two months. If you have a system like mine, it requires a new filter every six months and cost $100.00, but yes my family is worth it.
