The Right Furnace, Sized Right

Replacement is a decision, not a default.

Plenty of furnaces get replaced that only needed a repair, and plenty of repairs get sold on furnaces that are past saving. The first thing we do is tell you which situation you are actually in. If a repair makes sense, we say so. If the furnace is done, we explain why, and what your options are at different price points.

When it is time to replace, sizing is everything. A furnace that is too big short cycles and wears itself out. Too small, and it runs flat out on the cold nights without ever catching up. We size the unit to your home, walk you through the efficiency options, and give you the full number before the work starts.

FAQ

Furnace replacement questions

Age, repair frequency, and the nature of the failure all factor in. A newer furnace with a failed component is usually worth repairing. An older unit that keeps breaking down, or one with a serious fault like a cracked heat exchanger, is usually better replaced. We diagnose first and give you the honest reasoning either way.

It depends on more than square footage. Insulation, windows, ceiling height, and layout all affect the heating load. We size the unit to how your home actually holds heat, because an oversized furnace short cycles and an undersized one never keeps up on the coldest nights.

Annual Fuel Utilization Efficiency measures how much of the fuel you buy actually becomes heat in your home. An 80% AFUE furnace turns 80% of its fuel into heat and loses the rest out the chimney. Higher AFUE means lower running costs.

Yes. Caloris provides a two year labour warranty on all of our work. Manufacturer warranties on the equipment itself are separate and vary by brand and model, and we will explain what applies to your unit before you commit to anything.
