Common Furnace Repair Mistakes to Avoid

Getting your HVAC system in great shape helps keep your home safe and comfortable all year round. And when it comes to furnace repair, there are mistakes that homeowners should be aware of, in order to save themselves the hassle and inconvenience down the road.


Here are some of the common FURNACE REPAIR mistakes to avoid:

1. Performing DIY repairs on your furnace 


Repairing a furnace can easily cost hundreds of dollars, so it’s no wonder many homeowners attempt a DIY job to save money. However, your furnace is a complex system. If you’re not confident in carrying out a furnace repair job, it’s best to call an experienced heating and cooling technician.


DIY furnace repairs don’t only void the manufacturer warranty if ever the unit gets damaged, but they can also ignite fires if poor safety measures were taken. The job often requires the expertise of a professional and specialized tool that the average homeowner doesn’t have.

2. Using duct tape to patch up leaks


Duct tape isn’t for HVAC air ducts, as it reacts poorly to heat and temperature fluctuations. It shouldn’t be used in your HVAC system at all.


If you’re doing an HVAC job, foil or metal tape is the best option, since it’s flame-resistant and able to withstand extreme temperatures and high humidity.

3. Failing to shut off power to your unit during maintenance or repairs


Cutting off all electrical power ensures safety while working on the furnace.


The power to the furnace can be shut off either using the disconnect switch or at the circuit breaker. The disconnect switch keeps the power disconnected if ever the circuit breaker is turned on by mistake.

4. Skipping furnace maintenance


As a homeowner, you can do many things to help prevent costly repairs. But professional furnace maintenance is still the best way to keep your unit energy-efficient and in tip-top shape.


Maintenance does more than extending the lifespan of your init. It also keeps the filter from clogging and reducing the efficiency of your system. Diligently maintaining your furnace will significantly decrease the risk of an expensive repair, since small problems are fixed before they get worse.
