Changing the filter in your heating and air system is as important as changing the oil in your car. Unfortunately, it is easily forgotten by many homeowners and tenants, leading to higher utility bills and more wear and tear on your HVAC system. Filters help to protect your system and when they become dirty can restrict air flow to your system. Restricted air flow can cause your system to overheat and lead to serious problems for your HVAC system.

How often should I replace my air filter?

We recommend replacing your air filters every 30 days or as needed. The longer a filter is in place, the more dirt and dust build up and cause your system to work harder and decreases the efficiency. If you have pets in the home or suffer from allergies, it would be wise to replace your filters more often. If the filter is gray and covered in dust and lint, it’s time to replace it!

Why is replacing the air filter so important?

  • Extends the life span of your HVAC system: Unfortunately, heating and cooling systems don’t last forever. The typical life span is between ten and twelve years but for homes close to the coast that life span is cut in half. Replacing your filters every 30 days is one way that you can help prolong your system’s life. When a filter becomes clogged or dirty, your system has to work harder which in turn will increase your chance of having a breakdown.
  • Increases the efficiency of your system: If your filters aren’t replaced regularly, you may notice a spike in your electric bill. An HVAC system that is working extra hard to heat or cool your home is going to cost more money to run. Keeping filters clean is a sure way to keep utility costs lower.
  • Improved indoor air quality: Filters trap dust and debris but once it has become clogged, that dust is circulated throughout your home. Having a clean filter helps your system, home, and vents stay clean as well.

All HVAC systems need a filter that fits properly in order to keep your indoor air clean and your unit running at its maximum efficiency.
