The Often Overlooked Component: Air Filters in HVAC Systems

At VM O’Leary Sheet Metal & Heating, we frequently encounter customers who underestimate the significance of regular air filter replacement in their HVAC systems. This crucial component plays a vital role in maintaining indoor air quality and ensuring the efficient operation of your heating and cooling equipment.

Why Air Filters Matter

Air filters are designed to trap airborne particles such as:

• Dust
• Pollen
• Pet dander
• Mold spores

By capturing these contaminants, filters prevent them from circulating through your home and potentially causing respiratory issues or aggravating allergies.

The Technical Side of Air Filters

Air filters are rated using the Minimum Efficiency Reporting Value (MERV) scale, which ranges from 1 to 20. Higher MERV ratings indicate better filtration efficiency. For residential use, filters with MERV ratings between 8 and 13 are typically recommended.

The Impact on HVAC Performance

A clean air filter allows for proper airflow through your HVAC system, which is essential for:

• Maintaining energy efficiency
• Preventing strain on the system’s components
• Ensuring consistent temperature control

Replacement Frequency

The frequency of air filter replacement depends on various factors, including:

• Filter type
• Home size
• Number of occupants and pets
• Local air quality

Generally, we recommend checking your filter monthly and replacing it every 1-3 months for optimal performance.
