HVAC Air Filters Work Hard, Change Them Often 904

HVAC air filters

As temperatures dip lower every day, furnaces begin to work overtime, and HVAC air filters get dirty more quickly. If you haven’t cleaned or replaced your furnace filter lately, now is a good time to check on it. Blocked filters cause all sorts of annoying and potentially costly problems, but a clean HVAC air filter can cut energy costs, boost indoor air quality and keep your HVAC running smoothly and efficiently. Here’s why:

Energy Costs

The air filter in your furnace gets dirty simply as a result of doing its job, and when this happens it becomes more difficult for air to pass through. This causes your furnace to work harder, which eats up energy and can drive your utility bills through the roof. Changing your HVAC air filter when it gets too dirty cuts heating costs, and you can potentially save quite a bit more than the cost of the filters themselves.

System Health

Dirty, clogged filters are generally bad for your HVAC system as a whole. Excessive particle buildup puts a strain on your furnace’s blower motor, and can cause overheating and short-cycling, a problem that occurs when your furnace overheats, shuts down, then restarts only to shut down over and over again.

Another problem that can arise from dirty HVAC Air filters is that once a filter accumulates all the dirt it can hold, other particles are free to circulate throughout your HVAC system. These particles can settle in your blower motor, heat exchanger and any number of other places, where they can potentially cause long-term damage that will cost much more to repair then the price of a few clean filters.

Air Quality – Clean HVAC Air Filters

Forgetting about cost for a moment, clean filters simply do a better job cleaning your air, which is good for everybody. A clean filter grabs dust, dirt, fibers, mold spores and countless other particles much more efficiently than a dirty one, helping to keep you and your family healthy and breathing easy all winter long.

So exactly how often should you change your air filter? Unfortunately, there isn’t an easy answer to that question. It depends on a variety of factors, including the size of your house, whether or not you have pets, and if anyone in your household smokes. As a general rule, filters should be changed a minimum of once every three months, or at the start of each new season. Furnaces work hardest in winter, of course, so it’s not a bad idea to check on your air filter a little more often during the cooler months to make sure it’s not too grimy.
