When winter approaches and temperatures hit freezing, you want peace of mind knowing the furnace is going to turn on and blow hot air throughout your home.

It’s the absolute worst feeling when the furnace isn’t working and you need heat. That’s why it’s important to have an annual furnace tune up. The number one question we’re asked is if an annual furnace tune up is necessary. It is highly recommended that a tune up takes place every year by a qualified technician. In fact, furnace manufacturers often have in their warranties that damage caused by improper maintenance is not covered.

Newer furnaces can get by every other year but an annual tune up is highly recommended. You don’t want any surprises, you need to know that your furnace is functioning properly. Another question we get is what do technicians actually do to tune up a furnace. It really depends on where you go to have your service done and the language the company uses.

Unfortunately services provided by different heating companies do vary. Be sure to be up front and ask what all is included. Here is a basic list of what should be included in an annual furnace tune up by a qualified heating technician:

  • Vent system needs to be checked for blockage and leakage.
  • Combustion gases must be compared and analyzed to unit specifications.
  • Blower access door needs checked to make sure it makes a tight seal at the furnace.
  • The heat exchanger needs to be inspected for corrosion and rust.
  • The burners need to be checked for proper ignition, flame sense and burner flame.
  • The drainage system needs to be checked for blockage and leakage.
  • The blower wheel needs checked for debris and cleaned.
  • An amp-draw test should be conducted on the blower motor.
  • Wiring needs checked for corrosion and damage.
  • Filters need checked.
  • Static air pressure check.
  • Gas pressure testing.
  • Temperature rise checks.

How How Long and How Much?

A basic tune up by a professional will typically take up to an hour and cost around $50.  In short, it’s worth every penny. Think of it as a safety precaution and a preventative measure. If your furnace quits working in the middle of the night you will wind up paying a lot more for the emergency service fee.

Can I Do It Myself?

There are a lot of do it yourself homeowners out there that will try a furnace tune up on their own. However, as you saw above, a tune up consists of more than vacuuming dust. Most homeowners do not have the know how or the advanced experience to properly tune up a furnace. You don’t want to cut corners, that is why it is important to hire a professional.
