Why You Should Routinely Change Home Air Filters

Why you should routinely change furnace filters

Air filters are an important part of an HVAC system. However, they are often under-appreciated. They provide protection against larger objects, such as loose insulation. Air filters also screen out dust that can circulate through your home which lowers indoor air quality. Not changing your air filters frequently can cause clogging and earlier system failure resulting in a new heating and air conditioning unit. Over Fifty-Five Years of Experience in HVAC Service

TheEffects of a Dirty Air Filter

At some point, the air handled by the heating and cooling system passes through the air filter. As the filter accumulates dust along with the natural pollution of your home, the mesh where the air passes through becomes dense. This causes the permeability to degrease so the air cannot flow through it as easily.

  1. Increased Energy Use, Higher Bills, and Less Comfort

When air cannot freely pass, the blower fan in the HVAC system needs to work harder to push air. When this happens, it uses up more energy, which leads to higher bills.

If air has difficulty moving, your living areas will not get all the air they need. This will make your home uncomfortable, and temperature sensors that regulate the HVAC system may use up more energy as well, because of frequent fluctuation. Because of the pressure, your HVAC system will become strained and overworked. This can cause premature wear and tear on your HVAC system.

Aside from this, your HVAC system is also at risk of overheating or freezing up. This is because the heated or cooled air can’t travel out of the furnace, heat pump, or air conditioner that easily. You’ll be paying the same amount for no corresponding change in indoor temperature.

  1. It Becomes a Source of Pollutants

A clogged up air filter can provide room for moisture to gather, and encourage bacterial growth. As they build up on the wrong side of the filter, they introduce more pollutants and allergens into the indoor air. This can put you and your family at risk of health problems, as these allergens can also get into the HVAC system. Monthly replacement of your air filters can help prevent future health risks.

Change Your Air Filters Monthly

It is recommended to change air filters monthly, most especially if you have pets or if your home is located in a high-pollen area. Air filters do not cost a fortune, and changing them is a very simple task. You don’t need to wait until the air filter is completely filthy.

At the end of the day, clean air filters don’t just save energy and money. Going into the routine of monthly changing air filters helps your HVAC system run more efficiently, prolonging its lifespan.
