Changing your air filter is such a small task that is easily overlooked. However, the effects of ignoring it are not so small. If you haven’t changed your filter recently, it is probably clogged with all sorts of small particles, hair, dust, dander, possibly some mold spores and pollen. Changing the filter will allow air to flow through your vents easier and more efficiently, saving you money and improving your home’s indoor air quality.
Change your filter and voilà, better heating and cooling!
