Furnace Brand Comparison

Lennox, Trane, and Carrier are probably the 3 most popular brands of new furnaces in British Columbia. (Note that Trane also makes American Standard and Carrier also makes Bryant, Tempstar, and other brands.) This page will provide a quick overview of the furnaces offered by these brands, according to their published specifications.

Each of these 3 manufacturers offer a similar lineup of furnaces which can be divided into 4 different classes: furnaces with modulating gas valves and variable speed blower motors, furnaces with two stage gas valves and variable speed blower motors, furnaces with two stage gas valves and constant torque blower motors, and furnaces with single stage gas valves and constant torque blower motors.

Carrier makes a furnace that doesn’t exactly fit into any of these categories: a single stage furnace with a variable speed blower. They also don’t make a two stage furnace with a constant torque blower.

Note: If you want to learn what the terms above mean and the importance of the different features, then visit our furnace info page or watch our 5 minute video on new furnace options.

*Both Lennox and Carrier claim their higher-end furnaces are the quietest on the market. This is probably due to their different testing procedures.

It is apparent that Lennox is equal to or better than Trane or Carrier when it comes to the published specifications. But it isn’t by a large margin: The Lennox SPL99 (when looking at the 90-100K models, as this is a common size) is up to 3% more efficient than the comparable Trane and Carrier models, and has a burner which can operate at a slightly wider range of outputs (it can operate at as low as 35% capacity, compared to 40% for the competition).

The Importance of a Quality Installation

Although brand differences do exist, installation quality is usually the most important factor. Some brands of furnace may be rated at 2 or 3% more efficient that others, but improper installation can reduce performance by up to 30%!

The EPA has stated that, when it comes to heating and air conditioning systems, “more than half of new systems in U.S. homes do not perform to their rated efficiency as a result of improper installation. In fact, improper installation can reduce performance by as much as 30%.”

As the EPA says: “ A contractor who follows good sizing and installation practices may cost more, but the results can dramatically affect how well your new equipment will deliver comfort and savings.”
