Learning About HVAC Repairs

The heating season is quickly approaching, so it is a great time to check your system to prepare it for the drastic dip in outdoor temperatures. While surprising for many homeowners to learn, the filter is one of the most essential parts of the furnace. Not only does it trap in dirt, dust, and other allergens, but it also enables conditioned air a free passageway into the house. Changing your filter before the start of the heating season is smart, but most experts recommend changing it once a month for the most effective and efficient flow of air. The filter size will not change, but choosing from the different filter types can be overwhelming. Here are a few things to consider when choosing a filter for your furnace.

Actual Type

When selecting a disposable filter for your furnace, you will need to choose what material the filter is made of. Fiberglass is the most common option used by homeowners because it is readily available at most home improvement stores and is relatively affordable when compared to other options.

Polyester and synthetic filters are also good materials because they trap a  large portion of dirt and dust before it flows into your home. Of course, for the best filtration, consider a HEPA filter for your furnace. HEPA filters are capable of trapping in the smallest of particles, ensuring your home will be heated in a safe, allergen-free manner.

MERV Rating

The MERV rating is another element to consider when selecting a disposable filter for your furnace.

MERV ratings can range from 1 to 16 with the higher number being better, since the higher amount of particles will be filtered out. Unfortunately, this higher filtration also means less air will flow into the home.

Weighing out the pros and cons of higher MERV ratings is smart. However, if you are more concerned with allergies, a higher MERV rating is best.

Lifespan

Again, experts recommend replacing filters every month, but the actual lifespan of your filter will depend on a few factors.

If you or other family members smoke inside the home, the filters will wear down faster and may need to be replaced sooner. Also, if you have pets where hair and dander are flowing through the air or if you use an excessive amount of cleaners that may contaminate the air, your filters will most likely need to be replaced more frequently.

Ensuring your filters are clean and in good condition is key to your home's air flow. This guide will help you determine the right filter for your home's needs. Visit a site like https://www.advancedheatingandcooling.com for more help.
