Many HVAC systems rely on furnace heat exchangers to function. This piece of machinery warms air as it passes through it, then distributes it through the rest of your HVAC system. For such a simple operation, the function of a heat exchanger is quite complex and usually requires additional certification before a technician can touch it. Here are a few reasons why this machine is so complex.
If It Fails, It Could Have Serious Safety Consequences
If furnace heat exchangers stop working, the consequences are usually worse than just having a cold home. Since the heat exchanger is at the core of your HVAC system, it could cause knock-on damage to other components of your heating and cooling system, creating a very expensive problem if it isn’t treated in time.
A cracked or broken heat exchanger could also be a serious danger to you and your household. Furnace heat exchangers can release dangerous flue air or even carbon monoxide if they aren’t working properly, which could cause serious poisoning among members of your household. An HVAC technician needs to be certified to know how to repair these pieces safely.
The Metal Can Get Fatigued
Heat exchangers are put under a lot of pressure and degradation while they are in operation. Even though their metal components are made from tough materials, they can experience metal fatigue. It’s important that a technician knows how to recognize the signs of metal fatigue and can fix it or recommend replacements.
