Maintain Comfort All Year Long

Your HVAC system maintains the level of comfort in your home, and one of the most critical components to maintaining regularly is the air filter. This part seems small but plays a significant role in your home's comfort and air quality. Continue reading to learn more about the importance of your air filter.

What an Air Filter Does for Your HVAC System

An air filter is a vital component of any HVAC system and is essential in keeping your home comfortable and healthy. The filter traps airborne particles like dust, pollen, and pet dander, preventing them from circulating through your home. This not only improves air quality but also helps prolong the life of your HVAC system by preventing the buildup on vital components.

In addition, a clean air filter can also improve energy efficiency by reducing the amount of work your HVAC system has to do to circulate air. As a result, changing your air filter regularly is one of the best ways to keep your HVAC system running smoothly and efficiently.

How Often Should You Change Your Air Filter?

The air filter in your home does a vital job of trapping dirt, dust, and other airborne particles. However, over time, the filter can become clogged, which can reduce its efficiency and cause your heating and cooling system to work harder. As a result, it's essential to change your air filter regularly.

The frequency with which you need to do so will vary depending on your air filter type and the level of air pollution in your area. However, as a general rule of thumb, changing your air filter at least every three months is a good idea. Doing so can help ensure that your home's air is clean and fresh.

The Types of HVAC Air Filters Available

When protecting your HVAC system, one of the best things you can do is use a quality air filter. Various types of air filters are available on the market, and each has its own strengths and weaknesses. The most important thing to consider when choosing an air filter is the size of the particles it can remove from the air.

The three most common types of air filters are pleated filters, activated carbon filters, and HEPA filters. Pleated filters are suitable for removing large particles from the air, but they can quickly become clogged and must be replaced more often than other filters. Activated carbon filters are better at removing smaller particles, but they can be more expensive. HEPA filters are the most efficient for removing large and small particles from the air, but they can be more costly. When selecting an air filter, it is important to balance the cost with the efficiency to find the best option.

How To Change Your Air Filter

Changing your air filter is a simple task that only takes a few minutes. First, locate the filter housing unit and remove the old filter. Be sure to dispose of the old filter properly - do not simply leave it in the housing unit. Next, insert the new filter into the housing unit and close it up. Once the housing unit is closed, turn on your HVAC system to circulate the new air through your home. After a few minutes, you should notice that the air in your home is fresher and cleaner. So remember to change your air filter regularly!
