Why You Should Change Your Furnace Filter

A furnace filter plays a crucial role in maintaining the air quality in your home and ensuring your HVAC system runs efficiently. Here are a few reasons why you should make changing your furnace filter a priority:

Improved Air Quality: A clean filter helps remove airborne particles like dust, pollen, and pet dander, improving the overall air quality in your home.
Enhanced HVAC Efficiency: A dirty filter can restrict airflow, causing your HVAC system to work harder to heat or cool your home. By changing the filter regularly, you can ensure your system runs smoothly and efficiently.
Preventing System Malfunctions: A clogged filter is a common cause of HVAC system breakdowns. By changing the filter on time, you can reduce the risk of costly repairs.

How Often Should You Change Your Furnace Filter

The general rule of thumb is to change your furnace filter every three months. However, there are certain factors that may require more frequent filter changes, such as:

Pollen: During peak pollen seasons, consider changing your filter more often to alleviate allergy symptoms.
Construction Dust: If you’re undergoing home renovations or construction, dust particles can accumulate in your filter quickly.
Cold Spells: In colder months when your furnace is running more frequently, check your filter more often.
Flat Panel vs. Pleated Filters: Flat panel filters should be changed every 30 days, as they are less efficient than pleated filters.

How to Determine When to Replace Your Furnace Filter

To determine if it’s time to replace your furnace filter, follow these steps:

Hold it up to Light: If light passes through the filter easily, it’s still good. If not, it’s time to replace it.
Check for Clogs: If the filter is gray or visibly clogged with dust, hair, or debris, replace it.
Gray Filters: Even if your filter is light gray, it may need replacing if airflow is restricted.

Remember, maintaining a clean filter not only helps your HVAC system run efficiently but also improves the quality of air in your home.

The Cost of Changing Your Furnace Filter

The cost of furnace filters can vary depending on the type and efficiency rating. Here’s a general breakdown of costs:

Flat Panel Filters: $1 to $3 per filter (MERV 1 or 2)
Pleated Filters: $6 to $29 per filter (MERV 8 to 13)

Most homeowners can change their own filters, saving on labor costs. However, if you prefer, you can incorporate filter changes as part of an annual HVAC maintenance visit, which typically costs around $195.

Tips to Keep Your Furnace Filter Cleaner

In addition to changing your filter regularly, here are some tips to help keep your filter cleaner for longer:

Regular Maintenance: Schedule regular maintenance for your HVAC system to keep the blower assembly clean.
Professional Cleaning: Hire HVAC technicians to clean hard-to-reach areas within the furnace, like the blower assembly.

By following these tips, you can ensure your filter lasts longer and your HVAC system runs smoothly.
