When and why should I change the air filter in my house?

Air filter

Often people know they should change the air filter in their house, but they either forget to do it, don’t know when to change it, or don’t make it a priority on their “to do” list.  This is a job that needs to be done regularly to ensure your HVAC system runs smoothly. If you don’t change your filter regularly, you could be causing your furnace to run overtime, costing you more money.  Furthermore, it could be damaging your HVAC system which would require expensive repairs. Or worst case scenario: you might have to completely replace your HVAC.

So, take the time to replace your air filter on a regular basis.  At a minimum, replace it every 3 months.

Why replace your air filter?

-A good sign that you need to change your filter is how often your HVAC runs.  With more dust and debris in the system, the harder it has to work.

-If you have pets in the house, especially ones that shed, check and change the air filter more frequently.

-Check and change the filter regularly if someone living in the house has asthma or allergies.

-If you live in an area where there is a lot of construction or dust, change your filter more often.

-The time of year or the season affects how often you should change the air filter.  If it is cold outside, and you are running the furnace more often, check the filter every 30 days to see if it needs to be replaced.

-If the air quality in the house seems poor, this could be a sign that it is time to change the filter.

Overall, if you replace your air filter on a regular basis, you can avoid higher energy bills. You will also promote healthy air quality, and prevent damage to your HVAC system. Having to replace your HVAC system because of a dirty filter is completely avoidable. Use a good filter, and pay attention to the signs that you need to replace it.
