Knowing your HVAC system's components, like the furnace filter, and how they work is pivotal to keeping your home comfortable and efficient. A furnace filter is a screen that traps pollutants and protects your furnace from damage. Though often overlooked, it plays an indispensable part in maintaining air quality and system performance. 

Furnace maintenance, like filter replacement, is essential to extending its lifespan; for Tennessee residents, AVU Heating & Air is prepared to assist with any essential furnace maintenance and repair. Read on to learn more about furnace filters and their purpose.

What is a Furnace Filter?

A furnace filter is a screen usually inserted in the furnace's blower compartment. You can generally access it through a metal door or hatch, but its location may vary depending on the type of furnace you have in your home. 

The type of filter used in your home and its cost will change depending on the type of furnace you have. Different filters have different MERV scores, which can tell you how well they can trap particles and keep your air free from common pollutants.

How Does a Furnace Filter Work?

Furnace filters capture airborne particles as air moves through your HVAC system. Made from materials like fiberglass, pleated paper, or cloth, these filters act as barriers, trapping dust, allergens, and mold spores. This process enhances the air quality in your home and protects your furnace by keeping its components clean and reducing strain.

Keeping your furnace filter clean ensures system efficiency. When the filter is clear, air flows smoothly, allowing the furnace to function effectively. On the other hand, a clogged filter can hinder airflow, forcing the system to work harder and potentially increasing energy costs. A clean filter can significantly impact both comfort and expenses.

Different Types of Furnace Filters

Choosing the right furnace filter involves understanding the options available:

• Fiberglass Filters: These are economical and helpful for capturing larger particles like dust and lint, though they might not catch smaller allergens.
• Pleated Filters: Made from polyester or cotton, these filters offer a larger surface area for capturing more particles, making them a popular choice for improved air quality.
• HEPA Filters: Known for their high efficiency, HEPA filters can capture 99.97% of particles as small as 0.3 microns. However, their density may restrict airflow in systems not designed for them.

Selecting the right filter depends on your needs, such as allergen reduction or budget. Consulting an HVAC professional like the technicians found at AVU Heating & Air can help ensure compatibility with your system.

Maintenance Tips for Furnace Filters

Regular maintenance of your furnace filter ensures optimal performance. Here are some tips:

• Check Filters Monthly: During peak usage, inspect your filter monthly to see if it needs replacing.
• Replace Every 1-3 Months: Depending on the type and usage, replace the filter every one to three months. Homes with pets or allergy sufferers may need more frequent changes.
• Watch for Signs of Inefficiency: Increased dust, higher energy bills, or uneven heating can indicate a clogged filter.

Neglecting filter maintenance can lead to reduced efficiency, higher energy costs, and potential HVAC damage. Staying on top of these tasks ensures a healthier home and prolongs your furnace's life.
