When you hear someone refer to the HVAC system, the initials refer to heating, ventilation, and air conditioning. The air is constantly circulating through your home and flowing through the furnace filter before being sent through the ventilation system to your rooms.
Some furnaces require the filter to be changed every month for the most efficient filtering of the air and if you have pets in the house, it can be critical to do this once a month chore. Not only do filters protect the air coming out of the furnace, but they also protect air going into the furnace through the filter so the insides of the furnace stay cleaner.
Other newer systems may use a filter that can go six months or more. A good HVAC system exchanges indoor air with outdoor air to reduce indoor moisture, odors, and other pollutants. As the air is exchanged, the filter collects the dust, pet hair, and other particles in the air and filters them out so the air in your home is cleaner. If the filter is left dirty, or full of particles, this residue makes your system less efficient and shortens the life of the furnace.
Schedule Filter Changes
If your furnace requires monthly filter changes, pick one day of the month to take care of this on the same day each month. Keep a supply of filters so you only have to buy more a few times a year. If you can go longer between filter changes according to your owner’s manual, do this on the same date, such as June 1st and December 1st, or whatever length of time is recommended.
Changing filters is too important to leave it to chance. You will be protecting your family against dust, odors, allergies, and pollutants.
