The furnace—it’s there, but nobody seems to care about it that much until it breaks down. Well, if you want to avoid experiencing the hassle of a broken furnace, it’s about time you change this mindset, starting by knowing a little more about filters. Filters are the main thing that keeps you from inhaling all of the dust and dirt in your home.
One of the primary reasons for furnace replacement in Utah is the lack of attention given to filters. Changing it and keeping it clean is of paramount importance.
What It Does
The indoor air you breathe is clean because your furnace filter does its job. That is, remove contaminants and prevent dust and debris from building up and ruining the other parts of your HVAC. If there’s a lot of dust buildup in your unit, it will have a massive impact on its performance, make it easier to break, and increase your power consumption.
Filters have different ranges of efficiency, ranging from MERV (minimum efficiency reporting value) 1 to 20. For residential homes, the recommended range is from MERV 8 to 13. Any filter with a lower MERV rating than that would be ineffective in removing dust, debris, and other contaminants. A MERV rating higher than 13 would make the filter incompatible with most residential HVAC systems and could instead do more harm than good by blocking the airflow.
When It Needs Replacing
Cleaning your filter should be routine, and so should replacing it. The rule of thumb is to replace it after a certain amount of time depending on how thick it is.
If the filter is 1 to 2 inches, it’s best to change it between one to three months. For filters that are 3 to 4 inches, the time frame is six to nine months. Big filters that are 5 to 6 inches should be replaced every nine to 12 months.
Be sure to check your filter every month and get in touch with a contractor if something seems off.
