Furnace Replacement

Furnace Replacement & Installation Service in GTA

Replacing you old, poorly performing furnace might be one of the best decisions you’ll make all year. While the average furnace can last you up to 15 years, it’s never recommended to keep it on past it’s prime, as the average furnace becomes less effective in heating your home over time.

The longer you stick with your old, failing furnace, the more you spend in the long run on energy bills and maintenance. Moreover, the unsteady flow of heat limits your home’s comfort in the winter months. Sometimes the best solution is to simply consider a furnace replacement, and choose one of the new, energy efficient brands on the market.

If you’re unsure about when to get your furnace replaced, you can simply call us in for an inspection. However, we always recommend regular inspections once the furnace is over 15 years old, as that is generally the limit of the lifespan of the appliance. Other signs that you may need a new furnace are:

  • strange noises
  • higher monthly bills
  • poor heating
  • a yellow burner flame which can be indicative of carbon monoxide

In many instances, it is cheaper and easier to simply replace a faulty or broken furnace instead of attempting to fix it, which is why we always recommend you contact us for an inspection before making any decisions.
