A contempo blog post about autumn maintenance mentioned having your furnace inspected/tuned up past a qualified heating contractor annually. One reader sent an email request if this was actually necessary – hither's his original question:

"I have a question about furnace tune-ups. Y'all say get 1 every year – is that really necessary? What do the HVAC guys really do to the furnace to 'melody' it upward? There's no spark plugs to replace like a car tune-upwardly, and my understanding is they basically vacuum out dust and inspect it. Couldn't the homeowner exercise this himself? Or practise I actually need to pay $80-$150 every yr for a professional person to do information technology?"

These are great questions worthy of a post all on their own.

Are annual furnace inspections really necessary?

Furnace manufacturers all recommend almanac 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 the warranty. Does this mean that an annual furnace checkup is actually required, or the warranty is voided? Probably not, simply it'southward recommended. The best analogy is going to the dentist every half-dozen months for a checkup and cleaning; probably not necessary, merely recommended.

Some HVAC contractors recommend getting newer furnaces checked every other year, merely once they're more than 10 years old, accept them checked annually.

What do HVAC technicians actually practise to the furnace to "tune" it upward?

Information technology depends. According to Chris Jirak, a heating guy who has worked for several firms over a period of 25 years, the service you get when yous buy a $29 Groupon deal is going to be quite different from a $200 "tune-upwards." Jirak said that every contractor he has always worked for has had carefully worded language with subtle differences in the descriptions, making it nearly incommunicable to compare services betwixt different heating companies. A few services you may have heard of are "safety bank check," "certification," "checkup," "tune-upward," "bones tune-upwards," "complete tune-up" and "almanac maintenance checkup."

There seems to exist no manufacture standard for a furnace (or boiler) melody-up, and so what's included in a "tune-up" will vary greatly from company to visitor. If you're going to rent a heating contractor to do a tune-upwardly on your furnace, ask them what they'll exist doing. Included below is a fractional list of generic stuff that different furnace manufacturers recommend be performed annually by a qualified heating technician:

  • The vent system needs to exist checked for blockage and/or leakage. This includes the outside termination and the connections at and internal to the furnace.
  • Combustion gases must exist analyzed and compared to the unit specifications.
  • The blower access door needs to exist 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 exist checked for proper ignition, burner flame and flame sense.
  • The drainage organisation 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 h2o replaced in the trap.
  • The blower bike needs to be checked for debris and cleaned if necessary (this requires complete removal of the blower bike).
  • 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 demand to exist checked (merely this needs to be done much more than frequently than annually).

In add-on to this listing, heating contractors say that they regularly exercise static air pressure checks, gas pressure testing and temperature rise checks.

Could the homeowner do this?

Of form, just the merely homeowners who are knowledgeable enough to do all the tasks listed above also happen to be heating contractors. If the merely thing your furnace tech does is stick a vacuum nozzle into the furnace and suck a footling dust out, sure, do it yourself. If your furnace tech does half the stuff on the list to a higher place, they're earning their go along.

Before you lot rent a company to practice a tune-upward on your furnace, inquire what's included. The company doing the work should be able to quickly rattle off a long listing of stuff they'll be checking.

Exercise I really need to pay $80-$150 every year for a professional to exercise it?

In short, yes. This is what a professional charges — maybe fifty-fifty more. For most heating contractors, $80 barely covers the trip charge. Keep in mind, this isn't merely about safety; it'due south besides about preventive maintenance. It's about sometimes catching a problem before your furnace quits working in the middle of the night. When you accept to rent a heating contractor to show up on a Sunday evening considering the furnace stopped working, y'all're probably going to end upwards paying emergency rates.
