Maintaining Your HVAC System: Why Air Filter Replacement Matters

At Absolute Mechanical Systems, we often emphasize the significance of regular maintenance for your heating and cooling systems. One crucial aspect of this maintenance is the timely replacement of air filters. This simple yet essential task can have a substantial impact on your HVAC system’s performance and your indoor air quality.

Why Air Filters Are Important

Air filters serve several vital functions in your HVAC system:

• Trap dust, pollen, and other airborne particles
• Improve indoor air quality
• Protect HVAC components from debris buildup
• Enhance system efficiency

The Technical Side of Air Filter Replacement

When it comes to air filter replacement, there are a few technical aspects to consider:

1. MERV Ratings

MERV (Minimum Efficiency Reporting Value) ratings indicate a filter’s ability to capture particles. Higher MERV ratings mean better filtration, but they can also restrict airflow if not properly sized for your system.

2. Filter Size and Type

Using the correct size and type of filter is crucial. An ill-fitting filter can allow unfiltered air to bypass it, reducing its effectiveness.

3. Replacement Frequency

The frequency of replacement depends on various factors, including:

• Filter type
• HVAC usage
• Indoor air quality
• Presence of pets

4. System Performance Impact

A clogged filter can restrict airflow, forcing your HVAC system to work harder. This can lead to increased energy consumption and potential system damage over time.

At Absolute Mechanical Systems, we recommend checking your air filter monthly and replacing it at least every three months. For homes with pets or high HVAC usage, more frequent replacements may be necessary.

By maintaining clean air filters, you can ensure optimal performance of your heating and cooling systems while enjoying cleaner, healthier indoor air in your Brookline, NH, Milford, NH, Nashua, NH, Amherst, NH, Pepperell, MA, or Hollis, NH home.
