Inside of a furnace

Wondering if you can tackle that routine furnace tune-up yourself? Before you decide, let’s look at what happens during a furnace tune-up and when it’s a good idea to bite the bullet and call in the reinforcements.

What Happens During a Furnace Tune-Up?

Here are some things a Jennings Heating and Cooling technician will do when checking out your furnace.

  • Inspect, clean, or possibly change your air filters.
  • Make sure the blower speed has the right airflow.
  • Calibrate and evaluate the thermostat operation.
  • Clean the condenser and evaporator coils.
  • Clean and adjust any blower components that need it.
  • Check and tighten all electrical components.
  • Lubricate the moving parts of the furnace.
  • Inspect the condensate drain.
  • Evaluate the heating cycles and safety controls.
  • Clean and vacuum the burners.
  • Monitor and adjust the gas pressure.
  • Look for gas leaks in the furnace.
  • Do an electronic carbon monoxide test to safeguard your surroundings.


Which of These Tasks Can You Handle?

Deciding which tasks you can handle yourself really depends upon your comfort level and how competent you are with machinery. Not everybody is the handy type of person and there’s no shame in that.

One thing almost everyone can do and should do about once a month is to inspect and change their furnace filter. It just takes a few minutes, but it can stop your furnace from working too hard and prevent dangerous furnace fires.

That may be all you’re comfortable doing, and if so, that’s perfectly fine. Other people who have spent a little more time around furnaces can do other things, such as inspect the condensate drain to ensure it’s working properly. Anything beyond inspecting is probably best left to the experts.

Leave it to the HVAC Pros

There are some things, however, that are better left to the experts—no matter how handy you are. The technicians have the know-how and the proper equipment to ensure the job is being done correctly, and that your furnace, warranty or overall safety won’t be compromised. Some of the things that are best left to the experts include tightening the electrical connections, lubricating all the moving parts, checking and adjusting the gas pressure, and looking for gas leaks in the furnace.
