What Happens When You Don’t Change the Air Filter on Your HVAC System?

We all lead busy lives and have many things to tend to daily, so it is no surprise that many people often forget to change the air filter on their HVAC unit. This filter is vital to your system’s health and it is the unsung hero of the HVAC world. Neglecting to change the air filter is one of the most common issues we come across. Air filters work hard to keep particles out of your air but more importantly, they keep dirt and grime from building up on components. When you don’t change the air filter in your system, you could be heading for some undesirable consequences. Read below to find out about why it is necessary to change the filter regularly in your home.

Why You Should Always Change the Air Filter Regularly

There are many aspects of HVAC maintenance and servicing that can be complicated and costly. Thankfully, changing the air filter is not one of them! This is possibly one of the easiest things you can do to help your system last longer and run more efficiently. However, if you don’t change the air filter, you may have to deal with some unwelcome results.

Here some outcomes that can come as a result of not changing your air filter:

  • Grime Build-Up – Air filters are secretly working around the clock to keep your system running smoothly. They keep damaging dust and grime from building up on sensitive HVAC components. If you don’t change the air filter, these elements will enter your system and can cause problems. Moving parts of an HVAC system can be damaged by dust build-up over time.
  • Reduced System Lifespan & Frequent Breakdowns – Building off the previous point, dirty filters that allow build-up can lead to increased wear and tear on your system. When clogged with dirt, your system has to work harder to move air. This means that a little issue could snowball into a big, expensive fix over time. Changing a filter is much cheaper than a major breakdown.
  • Impacts on Filter Efficiency – In addition to dust and dirt, high efficiency filters collect things like allergens and pollutants. These filters must be changed regularly as a build up can reduce filter effectiveness, thus allowing these particles to pass through. This could greatly impact the health of people in your home or building.

You Should Change the Air Filter Roughly Every Month
