Do not wait until things break down. If you maintain them properly, the furnace and air conditioner have a lifespan of about 15 to 20 years. Schedule an annual appointment with a heating and cooling professional who can check that these workhorses are running efficiently and safely.

In between visits, make sure you change the furnace filter every three months. A clogged filter means that your furnace has to work harder, which increases energy usage. Plus, a clean filter means to improve air quality in your home because it catches bacteria, pet dander, and other contaminants that can be particularly harmful to those with allergies or asthma.

In Ontario, most homeowners rent a water heater, but in Alberta virtually nobody does.
It’s hard to explain the difference other than habit. Whether one or the other is a better deal depends on how you look at it. In straight cost terms, over time buying is a better deal. When you factor in convenience and hassle-free service for many people renting may be worth the extra cost.
The cost of renting in Ontario is between $13 and $26 a month from Direct Energy or Reliance Home Comfort depending on the size of the heater. You don’t have to worry about maintenance or replacement. When you buy you’re on the hook for any issues that arise after the warranty expires.
