Best Furnace Brands in Ontario 2024

What to Consider When Buying a New Furnace

A great furnace is determined by its features, not its brand. There’s only a small number of manufacturers that produce most of the furnace brands on the market. To find a great furnace it’s important to look at the features of an individual furnace model rather than the brand.

Here is list of features to consider when purchasing a new furnace for  your home:

  • Sizing: Choose a furnace that is the right size for your home. An oversized furnace isn’t better, and an undersized furnace won’t be cheaper.
  • AFUE Rating: The higher the AFUE rating, the less energy the furnaces uses, and the more money you save.
  • Warranty Protection: A great warranty will save you money in the long term and protects your furnace in the case of any necessary repairs or replacements.
  • Modulating or Two-Stage Capability: Furnaces with these features operate more efficiently, are quieter, and able to keep your home at a consistent temperature throughout the day.
  • Variable-Speed Blower Motor: Elevates comfort, reduces energy consumption, and allows for quiet operation.
  • Durable materials: A furnace with a stainless steel heat exchanger is always a good sign.
  • Professional Installation: Only trust certified professionals to install and maintain your furnace. An improper installation can cause a multitude of problems.
  • Wallet-friendly: Pick a furnace that falls within your budget, whether that means basic, mid-range, or high-end.
  • Extra features: Extras like WiFi connectivity and noise reduction improve both convenience and comfort.

If you have a furnace that’s over 15 years old, needs frequent repairs, and your energy bills are rising, it’s a good idea to invest in a new high-efficiency furnace.

How to Assess Furnace Reliability

Your assessment of furnace reliability should focus on the following key factors:

Technical details: Specifications to look for in a new furnace include:

  • Energy efficiency
  • BTU Output
  • Build quality
  • Design features
  • Additional capabilities like WiFi connectivity, air-purifiers, noise, reduction, zone control, and more.

Warranty: A great warranty is a sign that the manufacturer believes in their product’s reliability and is willing to back it. A long-term warranty is an indication of a high-quality furnace.

Reputation: The feedback and reviews by industry professionals and customers provides a wide range of data on furnace reliability and quality. If it’s trusted by HVAC professionals and customers alike then you know it’s a great product.
