Heat Exchanger Installation & Repair Services

Heat exchangers are the heart of any furnace. As with any fossil fuel, when burnt, fumes containing carbon monoxide, carbon dioxide, water vapour and soot are produced. A furnace heat exchanger has to safely contain these dangerous fumes and safely conduct them through approved vent pipes or chimney while transferring absorbed heat into the home.

Heat exchangers compromised with crack(s) or rust will leak flue gases and carbon monoxide into the home resulting in illness and possibly death of the occupants.

Why Do Exchangers Crack?

Almost all heat exchanger cracks are caused by overheating.  Overheating in turn causes excess stress from expansion and contraction. Weak areas near bends or welds are where most cracks appear.

Dirty air filter is one of the most common causes of overheating. Another cause of overheating is an oversized furnace.

It is important to always consult with professional and trained sales consultant when replacing or buying a new furnace.

An oversized furnace will short cycle or heat the home so fast that has to shut off after a few minutes leaving the heat exchanger wet from condensation causing it to rust from the inside.

Can Exchangers Be Repaired?

Heat exchangers, unfortunately, cannot be repaired the only cure is to replace them. Because the heat exchanger is placed behind all major components in the centre of the furnace, the whole furnace must be disassembled. Although parts are under warranty, delivery and labour is costly and chargeable. Depending on the age of furnace and cause of heat exchanger failure, the best cost effective solution is to replace the furnace.
