Changing a furnace filter in Kitchener-Waterloo. 

air filtersChanging a furnace filter is the fastest and easiest way to maximize the efficiency of your heating system—and help clean your home’s air.

What is a furnace filter? Put simply, it is a removable filter that is designed to trap the dust, dirt and other airborne particles in your home’s air. Filters prevent damage to your heating system by catching these particles. More expensive furnace filters perform a similar role, and can also enhance the air quality in your home by trapping pollen, bacteria and mildew.

A dirty filter reduces the airflow through your furnace, so it is essential to change these filter whenever it becomes too dirty! What happens? Low air flow causes the temperature in the heat exchanger to increase, causing a safety limit switch to turn the furnace off for safety reasons.

When it is time to change a furnace filter? It depends on the home, but roughly every 30 days for standard 1” filters. Larger or electronic filters can go 2, 3 or 4 months. Factors that affect the air quality of your home can change how often you should replace your filter as well, such as:

  1. You have cats or dogs.
  2. You notice excessive dust buildup in your house—yuck!
  3. You or someone you live with smokes.
  4. Your heating system fan runs often.

Here is a step-by-step guide on how to change it:

  1. Find out what size of filter you have so you can buy a new one.

HVAC tip: To find out what size filter your furnace uses, remove and check the old filter (the size will be written on the filter’s frame).

  1. Turn your furnace off!
  2. Make sure you install your filter facing the right way. Many filters will have an arrow that will tell you which side to face toward the blower motor.
  3. Slide the new filter into your furnace.
  4. Turn your furnace back on and you are done!

Why do furnaces break?

Why do furnaces break? The simple answer is … lots of different reasons.

At Afterglow, we get asked that question all the time.

It never fails… we ring the doorbell, walk into a home that has electric heaters plugged into every outlet. We follow the homeowner to the basement and find the sad, quiet, and old furnace that refuses to do its job.

Here are the top 4 reasons your furnace died at the worst possible time:

1.   Parts Fatigue: This is the top reason. The furnace has been working with many on-off cycles, just like city driving, causing one or some of the parts just stop working.  An annual 15 –point furnace checkup can be proactive.

2-   Cheap furnace: Do your research. A good manufacture will build a good furnace and it will last longer than a piece of junk every time.

3-  Professionally installed: If the furnace is not installed properly it will not work up to its full potential.  Afterglow technicians are well trained and agile, problem solvers.

4-   Environmental Reasons: These problems are unique to each site. Kitty litter, pets, children, saw dust, dryer lint, spider webs, humidity and water softener salt all contribute to a furnace’s failure. Regular maintenance can help add years to your furnace.
