A little thing like a clean air filter makes

a big difference to your air conditioning system.

Scott’s Heating & Air Conditioning offers a variety of specialty and standard filter sizes. Give us a call to order your filters, and we will deliver them to your home.

Things to Know:

Size Matters – Filter sizes are advertised in nominal sizes, but there can be 10 filters in that nominal size and only one will fit your system. Either measure the filter or look for a model number, filter number or item number.

For example, a filter that is 16” x 25” x 5” can actually measure 15 ¾” x 24 ½” x 4 ¾”.

Thickness Matters – Air filters can range in thickness from 1” to 5”. You’ll need to know how wide your filter needs to be.

Merv Rating – Ratings go from Merv 1 “Okay” to Merv 16 “Best”. A higher Merv rating may cost more, but they last longer too.

When should you replace your filter?

Knowing when to replace your filter will protect your heating and cooling equipment. Did you know… the #1 reason for an air conditioner, air handler or furnace not working well is a dirty filter! Here are some guidelines on when to change your filter:

Disposable Mesh Filters (Merv 1-4) – 1 month or when it looks dirty

Pleated Filters 1” or 2” (Merv 5-8) – 1-3 months, visually check your filter

Pleated Filters 3”, 4” or 5” (Merv 8-16) – 6 months – 1 year, visually check your filter
