So What Exactly Happens During A Furnace Tune-Up? - Sun Heating & Cooling, Inc.
Furnace tune-up

It’s general knowledge that furnace maintenance and repairs are best left to the experts! But do you know what goes on behind the scenes of a routine furnace tune-up?

If not, here are three things you can expect your technician to do when they pay your home a visit!

Ignition check

An igniter is a small device to light your furnace and heat the gas. The igniter switch is utilized every time your furnace comes on, so it’s important to ensure that it is functional. In older furnace models, a pilot light is built into the furnace to light the gas. But newer models either include it as an alternative option to the igniter or scrap the pilot light altogether.

The igniter is one of the more likely parts of the furnace to fail, so your technician will inspect it to find out the following:

  • If the igniter is still working as expected
  • Issues that it will likely develop in the future, and
  • How long will it last before needing to be replaced

Flame sensor inspection

Furnaces utilize gas and fire to heat your home. These two things could potentially be dangerous if not kept in check. This is where a flame sensor comes in. The flame sensor determines whether a flame is present in the furnace while running. If a flame is detected, everything should run smoothly. But if not, the flame sensor will cut off the gas supply to prevent a leak and likely an explosion. Dust, dirt, and other debris build up on the flame sensor. And this reduces its sensitivity and may cause the furnace to turn on and off.

Hence, your technician will inspect the sensor and ensure it is functioning properly!
