Do I need to change my furnace filter in the summer?

Spread the love

When people think about furnaces, they automatically think about winter and rarely relate to furnace maintenance. Given the heat so far this season in Southern Ontario, most people may have even forgotten that they have a furnace in the house. It’s also why many homeowners are surprised when they are told that they should make it a point to change their furnace filter in the summer months too. They wonder why it’s necessary to change the filter when the furnace isn’t being used at all in the summer.

So why should you bother about changing the furnace filter, even in the summer? Well, take a look:

Today, most HVAC systems have extensive ducting; the forced, heated air from the furnace flows through this ducting. It’s also important to keep in mind that your central air-conditioning also flows through this same ducting. In addition, the air exchange systems exchanges the air from within your home, and the outdoor air, via these ducts.

Many people do like to throw open the windows of their homes, in the summertime. While that brings in fresh air, it also brings in a lot of dirt and dust. The filter can become clogged with pet dander, pollen, etc. even in the summer months (just as it does during the winter), and this makes it even more difficult for the air to get through. It won’t allow the airflow required for operation of the HVAC system.

The chain effect of this is that the HVAC system will have to work harder, which then leads to an increase in your energy bills. Most people are very particular about changing the filter in the winter months, but tend to overlook doing the same in the warmer months. You must keep in view the fact that all the air you breathe in the indoor spaces of your home, first flows through that filter; and so regardless of the season, it must be changed at regular intervals, without fail.

Furnace filter change- the benefits

  • The recommendation is that the furnace filter should be replaced at least every 3 months, or even on a monthly basis. Doing so will have a very positive impact on the indoor air quality and will keep dust and allergens at bay.
  • It will also increase the efficiency of the cooling system in your house.
  • Changing your furnace filter with regularity will help increase the longevity of your HVAC system as well as your furnace.

No matter which way you look at it, changing your furnace filter during summer benefits you in a number of ways. Don’t let the clogged furnace filters affect the working of your HVAC system or defile the air quality in your home, no matter what the season.
