For Canadians, nothing is more important to the comfort of your home than a fully functioning HVAC system. Keeping your system in peak condition for as long as possible will not only save you money on replacement costs, but can also potentially lead to lower utility costs, greater comfort and better indoor air quality. Here are our top 5 tips for extending the life of your HVAC system:


  1. Get a professional tune up

Properly maintaining your furnace and air conditioner will help them function efficiently and extend the lifespan of your equipment. No one knows the ins and outs of your heating and cooling system like a certified HVAC professional, so scheduling an annual tune-up either before the winter or before the summer will help keep your equipment in top shape.


  1. Change the air filter regularly

You’ve probably heard this one a lot, but the importance of regularly changing your air filter cannot be overstated. A dirty air filter causes your HVAC system to work harder in order to condition the air, which can potentially increase its wear-and-tear, and ultimately lessen its lifespan.


  1. Clean the outdoor condensing unit

In order to extend the lifespan of your HVAC system, it’s important to maintain the cleanliness of your outdoor condensing unit. The indoor components of your system are by and large protected by your home, but the outdoor condenser is not, making it prone to dirt and debris build up. Spray down the unit using the light pressure setting on your garden hose, and keep it free of debris like grass clippings, branches, leaves and dust.


  1. Clean and unblock vents

Much like a dirty air filter, your homes vents may cause your HVAC system to work harder than it needs to if they’re full of dirt and dust. Any time your system is straining to provide conditioned air, its lifespan can potentially decrease. Remove the grills on the floors or in the wall once a year at a minimum and clean them with a rag or a vacuum. Also, check to make sure that your vents are not being blocked by furniture, as that can cause undue pressure on your system.


  1. Take an AC time out

As is the case with most mechanical systems, your HVAC system will wear out quicker if it’s constantly running, day and night. If you plan to leave the house for an extended period of time, turn off the air conditioner. Using ceiling fans is another good way to give your HVAC system a break, and can potentially save you a significant amount of money on energy costs.
