An annual furnace inspection and maintenance conducted by a qualified Edmonton furnace service professional is a necessary step to keep your furnace in good working condition. If you have a new furnace, an annual checkup is also needed to ensure your unit’s warranty stays active.

You might be asking, what do furnace technicians do when they inspect and maintain your heating system? The answer is, it depends. The service you get will vary depending on the type of unit you own, as well as the furnace maintenance company that you choose to perform the job.

That said, there’s a list of 10 common tasks that different furnace manufacturers recommend being done on a year-to-year basis by a qualified HVAC technician. These include:

Could you do all these tasks yourself? In a way, yes, but you’d have to be knowledgeable enough about your heating unit to be able to do these tasks competently. If you want to make sure what’s being done, ask your furnace service company what’s included in the annual checkup. They should be able to quickly name the tasks that they’ll be doing.
