What Happens During A Furnace Tune Up?

As 2020 comes to an end, make sure to schedule your furnace tune up with a reliable HVAC contractor before the cold winter months. There are usually fun holiday preparations to plan for in December, so it’s better to get your furnace tune up out of the way. Otherwise, it can be easy to forget about this important home maintenance task. Schedule your appointment early so you can focus on enjoying the holiday season.

But before you call a local HVAC contractor, you may be wondering what happens when your furnace is serviced. Here are a few things to expect from a professional furnace tune up.


A major part of your furnace maintenance includes a thorough cleanup. Over time, most furnace parts tend to get a bit dusty and dirty. You can examine the outdoor unit itself, including the fan, and the drain line. But, for complex parts, like coils, it’s best to seek help from a professional. They can spend more time and effort on cleaning, without inflicting damage to the blades.


Your furnace also needs to be inspected. Due to its regular use during the winter season, it can be prone to wear and tear, cracks and other visual signs of potential furnace issues.

Maintenance Tests

Do you have either a gas or oil furnace at home? If so, your professional HVAC contractor will take tests on certain parts of your furnace. This includes testing the flow of air, the thermostat, fuel pressure, igniter and more. Tests are included in a furnace tune up in order to detect any possible danger from fumes and leaks.


This may not be required during each tune up, but if your HVAC contractor notices that the motor parts have dried out, they will apply a specialized lubricant to prevent it from becoming damaged.

The Importance of a Furnace Tune Up

Furnace maintenance is essential for every heating system in order to make sure that your furnace functions at its best. This, in return, will provide better indoor comfort for you and your family, keep your energy bill lower, and ensure that the unit is safe.

If you sense that something’s wrong with your furnace, a tune up can diagnose issues and solve them quickly. Most importantly, it prolongs its life, so you can make the most of it for more heating seasons to come.

Scheduling a Yearly Furnace Tune Up

Many homeowners simply forget to include a furnace tune up on their home maintenance checklist. Some, on the other hand, are still skeptical whether or not it’s really necessary. It’s important to schedule regular furnace maintenance because continuous usage, especially during colder months, can cause wear and tear on its components. This affects its overall system performance.

If you skip maintenance this year, you might not be aware of certain problems or the urgent repairs that your furnace needs. And, in time, you might realize that it’s one of the reasons why your energy bill is higher than usual, or you’re feeling less cozy in your living space.
