Advice for Changing Your Furnace Filter

September 11, 2019by admin0

When the temperatures start to fall, and there is less daylight, it is time to look at your furnace! It’s essential to have a well-functioning furnace to make sure that your home stays warm and cozy no matter the weather. During the fall and winter seasons your furnace will continuously be working to move air throughout your home at a specified temperature. This is the time to check that your furnace filter to ensure that your airflow is as efficient as possible.

The Number one reason for all heating and cooling related breakdowns is a dirty or overly restrictive filter. Unfortunately, most people, buy the most expensive media filter available. Yes, they do stop dirt and dist from moving through the air – but some filters are too dense and create too much static resistance in your HVAC system. This can lead to your furnace overheating, blower motor failing or AC coil freezing.

Furnace filters are easy to change and can be done by homeowners, without the aid of a trained furnace technician. Your furnace filter is changed regularly because they are a critical component of your furnace. They ensure that clean air is circulated through your home and more importantly, into your lungs! Consider installing a low static, washable Trane CleanEffects.

It’s always best to check and follow your owner’s manual to see what timing your furnace’s manufacturer suggests. A good rule of thumb is to change your furnace filters every 3-6 months. Typically, we recommend that to maintain a clean healthy environment in your home, changing the filter as the seasons change is always a good practice – once every 3 months (or 4-times per year).

It’s important to be aware that external factors can also influence how frequently you change your furnace filters. When your furnace runs, the filter will collect several airborne particles and debris that will clog up the filter, making it difficult for air to pass through. This causes your furnace to work much harder to heat your home, resulting in higher energy costs – and poorer quality air.  If someone in your family has allergies, then more frequent changes may be required and can potentially help reduce dust and pollen. Also, if your home has pets with significant dander, or you are in a dusty area where external factors such as new home construction, busy roadways, etc. might be an issue, then more frequent changes may be required.

Every home is different, and most people have different lifestyles that can affect the state of your filter. The best way to know when you should change your air filter is by checking it regularly. It’s always best to check with either your furnace’s manufacturer or call our team at Waterloo Energy Products and we’ll be happy to help you determine a schedule that will work for you.
