Commonly Asked Questions Answered About Furnace Tune-Ups


A furnace tune-up is an important service that can help keep your heating system running smoothly and efficiently. It is recommended that you schedule a tune-up once a year to ensure that your furnace is working properly and to prevent breakdowns.

Commonly Asked Questions About Furnace Tune-ups

A furnace tune-up is an essential heating maintenance service for your heating system. It involves a thorough inspection and repair of your system to ensure that it is running at optimal efficiency and safety. Here are some commonly asked questions about furnace tune-ups:

  • Are they necessary?
  • Do I need to get one every year?
  • What do the furnace guys actually do to the furnace to “tune” it up? There are no spark plugs to replace like a car tune-up, and my understanding is they basically vacuum out dust and inspect it.
  • Couldn’t the homeowner do this himself? Or do I really need to pay $80-150 bucks every year for a professional to do it?

Are Annual Furnace Inspections Really Necessary?

Furnace manufacturers all recommend annual inspections and maintenance by a qualified technician. They also have language in their warranties saying that damage to the units caused by improper maintenance is not covered under warranty. Does this mean that an annual furnace check-up is really required, or the warranty is voided? Probably not, but it’s recommended. The best analogy I can think of is going to the dentist every six months for a check-up and cleaning; probably not necessary, but recommended.

I think these are great questions worthy of a post all on their own.

I’ve heard some furnace contractors recommend getting newer furnaces checked every other year, but once they’re over ten years old, have them checked annually.

What Do Technicians Actually Do To The Furnace To “Tune” It Up?

It depends. The service you get when you purchase a $29 Groupon is going to be quite different from a $200 “tune-up”. Every contractor has had carefully worded language with subtle differences in the descriptions, making it nearly impossible to compare services between different heating companies. A few services you may have heard of are “safety check”, “certification”, “check-up”, “tune-up”, “basic tune-up”, “complete tune-up”, and “annual maintenance check-up.” The services provided by different heating contractors will vary, depending on who you call and what you pay. A “tune-up” will vary greatly from company to company. If you’re going to hire a heating contractor to do a tune-up on your furnace, ask them what they’ll be doing. Included below is a partial list of generic stuff that different furnace manufacturers recommend being performed annually by a qualified heating technician:

  • The vent system needs to be checked for blockage and/or leakage. This includes the outside termination and the connections at and internal to the furnace.
  • Combustion gases must be analyzed and compared to the unit specifications.
  • The blower access door needs to be checked to make sure it makes a tight seal at the furnace.
  • The fresh air intake grills and louvers need to be checked for blockage.
  • The heat exchanger needs to be inspected for rust and corrosion.
  • The burners need to be checked for proper ignition, burner flame, and flame sense.
  • The drainage system needs to be checked for blockage and/or leakage. This includes the hoses internal to the furnace. The condensate drain and trap need to be cleaned, and the water replaced in the trap.
  • The blower wheel needs to be checked for debris and cleaned if necessary – this requires complete removal of the blower wheel.
  • An amp-draw test should be conducted on the blower motor and compared with what is listed.
  • The wiring needs to be checked for corrosion and damage.
  • The filters need to be checked (but this needs to be done much more frequently than annually).

In addition to this list, heating contractors say that they regularly do static air pressure checks, gas pressure testing, and temperature rise checks.

Couldn’t The Homeowner Do This Themselves?

Of course… but the only homeowners I know who are knowledgeable enough to do all that stuff listed above also happen to be heating contractors. If the only thing your furnace tech does is stick a vacuum nozzle into the furnace and suck a little dust out, sure, do it yourself. If your furnace tech does half the stuff on the list above, they’re earning their keep. Before you hire a company to do a tune-up on your furnace, ask what’s included. The company doing the work should be able to quickly rattle off a long list of stuff they’ll be checking.

Do I Really Need To Pay $80 – 150 Bucks Every Year For A Professional To Do It?

In short, yes. This is what a professional charges – maybe even more. For most heating contractors, $80 barely covers the trip charge. Keep in mind, this isn’t just about safety; it’s also about essential preventative repair. It’s about sometimes catching a problem before your furnace quits working in the middle of the night. When you have to hire a heating contractor to show up on a Sunday evening because the furnace stopped working, you’re probably going to end up paying emergency rates.
The summary is that every important piece of equipment needs attention, such an important item in your home cannot be ignored. Remember that your furnace has electricity, gas, combustions, condensation, and other very critical items that need yearly attention. It’s not only a matter of comfort and efficiency but safety as well.
