Appleby Systems has been supplying and replacing furnace filters for homeowners in Oakville and Burlington since 1967. We stock model-specific filters for all major HVAC brands, including Carrier and Coleman, so that you can get the right fit without the guesswork.

Picking up the wrong filter, even one that looks similar, can restrict airflow, reduce efficiency, and put unnecessary strain on your system. That is why we stock filters by model, not just by size. If you are not sure what your unit takes, bring in your furnace model number or call us, and we will confirm the right filter before you make the trip.

We keep stock on hand for the most common residential units in the Oakville and Burlington area, and we can advise on how often your specific filter should be replaced based on your household and system type.

How Often Should You Change Your Furnace Filters?

How often you need to change your filter depends on a few household variables: the number of people in the home, pets, nearby construction, and the type of filtration system you have. Depending on these factors, your filter may need changing monthly, quarterly, twice a year, or annually. Appleby Systems offers competitive pricing to make regular furnace filter replacement straightforward.

Signs Your Furnace Filter Needs Changing

A clogged filter will result in a "no heat" situation in winter and a "no cooling" situation in summer, meaning little or no airflow from the furnace into your home. If the filter is blocked with dust, the furnace works harder to push air through, which drives up your utility bills and shortens the life of the equipment.

Think of it like trying to breathe through a straw. The harder your system works, the faster it wears out. A neglected furnace filter puts unnecessary strain on your entire heating and air conditioning system.

Common signs your filter needs changing:

Reduced airflow from your vents
Dust buildup on surfaces near vents
Your furnace is running longer than usual
Increased energy bills with no obvious cause
Visible dirt or discolouration on the filter itself

Types of Furnace Filters and the MERV Rating

Furnace filters come in several types, each with different performance levels and replacement schedules:

Disposable 1" filters: the most common type, typically replaced every 1 to 3 months
Pleated filters: capture smaller particles and last up to 3 months
Electrostatic filters: use static charge to attract particles, washable or disposable
Permanent washable filters: reusable but require regular cleaning
Media filters: thicker, high-capacity filters suited to households with allergy or asthma concerns

MERV stands for Minimum Efficiency Rating Value. The higher the MERV rating, the finer the particles it captures. Most residential systems perform well with a MERV 8 to 13 filter. Going too high can restrict airflow, so it is worth checking with your HVAC technician before changing filter types.

Furnace filter FAQs

Yes. We carry model-specific furnace replacement filters for all major brands, including Carrier and Coleman. Contact us to confirm availability for your system.

What does a furnace filter actually do?

A furnace filter traps airborne particles like dust, pollen, pet dander, and debris before they pass through your HVAC system. This protects both your equipment and the air quality in your home.

How often should I replace my furnace filter?

It depends on the filter type and your household. A standard 1-inch disposable filter typically needs replacing every 1 to 3 months. Households with pets, allergies, or multiple occupants may need to change more frequently. Thicker media filters can last 6 to 12 months.

What MERV rating do I need?

Most residential homes do well with a MERV 8 to 13 filter. If anyone in your household has asthma or severe allergies, a higher-rated filter may help. Going above MERV 13 without confirming your system can handle the airflow restriction is not recommended.

Can a dirty filter damage my furnace?

Yes. A blocked filter forces your furnace to work harder, which shortens its lifespan and increases your energy bills. In severe cases, it can cause the system to overheat and shut down entirely.
