How often should I change my home's air filters?
You should change your home's air filters once a month or as needed based on the manufacturer’s recommendations. Several highly efficient filters are available that can extend the useful life.
As the filters become loaded with dust and particulate, the air conditioning unit has to work harder, which means the power consumption increases. This bogs down the motor and can decrease the life of the unit. If you want your air conditioner to last longer and run more efficiently in the long run, it is very important to replace and clean your air filter regularly.
If you neglect to regularly maintain your air filters, you will probably realize that your air conditioner will take a longer time to cool and will consume more electrical power.
