Spring is here do you have indoor air to fear?
It's a good time to ensure your furnace is running in tip top shape and what better way to do that than to start with changing the furnace filter. The primary function of a furnace filter is not to improve indoor air quality but to protect your furnace and/or air conditioner and secondly improve your indoor air quality. Don't use a filter that can do more harm than good, the filter is your systems first line of defense.

What is the difference between Furnace Filters and Air Conditioner Filters?
There is no difference between furnace filters and air conditioner filters. If a filter is listed as a furnace filter it can also be used in a air conditioning system. More often than not they are referred to as furnace filters. Other terms you may hear are HVAC filters, home air filters, pleated furnace filters, basic fiberglass furnace filters and more. Your main concern should be the filter size and how well you would like to improve indoor air quality (IAQ).

Can't find your filter size anywhere?
Are you having a tough time finding your filter size? We can help by making you custom furnace filters to your exact size. Custom furnace filters provide the filtration and protection you need. The primary purpose of furnace filters are to protect your system, so with out a properly fit air filter the protection won't be sufficient. Custom furnace filters and AC filters will help protect your system and improve your indoor air quality.
