Why You Need to Change Furnace Filters in the Summer

At first glance, the words “furnace” and “summer” just seem incongruent; they don’t go together!  Why worry about changing your furnace filter in the summer? Because, most of today’s HVAC systems consist of ducting through which your furnace’s forced-heated air flows and your central air conditioning flows, in addition to an air exchange system that literally exchanges (in/out) the air of your home. Most of us just naturally tend to be fairly cognizant of changing that filter in the winter, but think of it less often, if at all, during the summer months.

Since all of the air that you breathe in your home flows through the furnace filter, it is extremely important that this filter be changed, at the very least, every three months if not monthly. The same HVAC system that moves air throughout your home during the winter, will be moving the  air throughout your home in the summer. Your air filter has an affect on the quality of  your indoor air, as well as the efficiency of your cooling system. Your filter can become clogged as it collects dust, pet dander, pollen, etc., making it more difficult for air to get through. It can cause the fans to work harder, thereby increasing your energy bill.  Frequent filter changes will help to increase the lifespan of your entire HVAC system.

So, yes, your furnace filter needs to be changed even in the summer. Don’t let dirty filters hinder the work of your HVAC system or harm your indoor air quality, regardless of the season. Anytime you need maintenance or repairs, make sure to call your local HVAC professional who can ensure the proper functioning of your ventilating system all year long.
