Why Do You Need A Furnace Tune-Up?

Updated 2/27/19 
 
A regular check-up for your furnace isn’t always top of mind or convenient. However, as we approach the frostier months, now is the smartest time to guarantee your furnace is ready to provide you maximum comfort throughout the season.

Among the leading ways to prevent a breakdown and make sure it runs efficiently is with yearly scheduled tune-ups on your furnace. Just like all mechanical equipment, the useful life of a furnace will be prolonged with preventive maintenance, by ensuring that all the elements of the unit are performing efficiently. Also, regular cleanings can help pinpoint issues before they become big problems and you end up cashing out for emergency rates on a cold winter night. Plus, because furnaces burn fuel to provide the heat, it’s important to inspect all the various components to ensure there aren’t any ruptures or leaks that could impact the safety of your family. Taking the time to schedule a tune-up, even when it’s not making that odd rattling noise you’ve been ignoring, will save you time, stress, and money throughout the heating season.

Is it true my warranty is voided if I don’t get my furnace serviced?


Most manufacturers’ warranties require yearly HVAC maintenance to stay valid, so skipping your tune-ups can possibly result in losing your heating or AC system warranty, which can be major money if your equipment does ever stop working in the middle of extreme temperatures. Make sure you get all you can from your warranty by ensuring it’s valid as long as possible with annual furnace system tune-ups from Becht/Givens .

What can I do to troubleshoot my furnace before calling a tech for service?


Here are a couple troubleshooting tips we suggest checking out early on in the heating season:

1. Inspect your home’s air filter

Air filters can easily be overlooked, but their importance to your home’s furnace efficiency cannot be overstated. Filthy air filters can mean a variety of comfort annoyances for homeowners, including:
  • working
  • Restricted airflow
  • Decreased efficiency
  • Bigger energy bills
If you take out your home’s air filter, hold it up to a light. If you can’t see light coming through it, it’s most likely been a while since your last heating service, and likely time to replace it. If it’s a simple disposable air filter, just get a like-size new one. It’s also a good idea to write down the date you installed the new filter, so you know how old it is next time it needs to be swapped out. Check the filter packaging to see how long the new air filter is supposed to be used.

2. Double check your thermostat.
  • One of the simplest tasks that homeowners can do is take a look at the thermostat.
  • Make sure it is set to Heat and not Cool, and that the temperature setting is above the current indoor temperature.
  • If you can’t remember the last time you replaced your thermostat’s battery, now is the best time to do it.
  • When first moving over to your heat setting, turn your thermostat up a few extra degrees to make certain that it is running as it should be and heating your home’s air.
3. Open up your air vents.

There’s a common misconception that you can boost your savings by shutting the vents (supply registers) in rooms that aren’t being utilized. Resist the urge to close too many, as doing so can actually increase the pressure in your furnace, making it work harder to heat your home. This can cause busted blower motors, mold or mildew in your ducts, damage to the compressor, a burst heat exchanger, and other problems.
  • Full inspection. The service should include a full visual and point examination to check all the working parts of your furnace and duct system. A qualified technician should be able to let you know if your equipment or individual parts are showing signs of wear during this review.
  • Lubrication. Mechanical equipment needs lubrication to eliminate friction between the functioning parts. Your furnace tune-up should include a complete lubrication.
  • Pilot and gas pressure adjustment. As part of your tune-up, adjustments should be made to the pilot and gas pressure if needed to restore these elements to OEM specifications.
  • Filter replacement. A comprehensive furnace tune-up should include a standard 1” filter replacement with your service. Most furnace filters need to be replaced at least every three months, which can enhance efficiency and prevent operational complications.
  • Written assessment. Quality HVAC companies should give you their analysis in writing or on the receipt with your tune-up, including their professional maintenance proposal for the next year. This important information can help you determine the current condition of your furnace and how you can lower your energy bills.

4. Is your Furnace Receiving Electricity?

Switch the thermostat to “on” from “auto” to force the fan to turn on. If the fan turns on, power is working correctly, but if it doesn’t, your furnace could be lacking power.

5. Is the Furnace Switch Operating Properly?


All furnaces have a power switch (that resembles a light switch) either on the furnace or on a wall close by. Flip the switch and wait a few minutes to see if it turns the furnace on. Also confirm that all access panels and doors on the furnace are completely closed.

6. Condensate Drainage


High-efficiency furnaces can drain off several gallons of water every day. If drain lines get clogged, the furnace will shut down.

7. Check Vents for Blockage


If you have a furnace that vents out the side of the house, assess the situation to see if anything could be blocking the intake or exhaust. Be sure the surrounding region doesn’t have leaves, animal nests, or snow/ice.

What Should You Expect After a Furnace Tune-Up?


Improved Function

Your heating and air conditioning system naturally loses energy efficiency over time. This loss of efficiency is due to a variety of issues, including dust and dirt, natural wear and tear, and buildup in drains or on burners. Keeping your heating system maintained with annual professional tune-ups can help to reduce these factors. During your tune-up, your maintenance technician will clean and check over your unit, identifying areas of wear and tear. They can identify failing parts in need of replacement before they become a bigger problem. A tune-up alone will sometimes instantly improve energy efficiency by up to 30%. You’ll also enjoy cleaner air and a cleaner house because your HVAC unit will be distributing clean air through a clean air filter. Perhaps one of the greatest benefits you’ll enjoy following a fall furnace or AC tune-up is diminished utility bills. A neglected HVAC system must work much harder to heat and cool your home, while a furnace or air conditioner that has been finely tuned can take less energy to guarantee indoor comfort. Because your heating system operates more efficiently, it will deliver superior heating at lower cost than you otherwise may have had during the coldest months of the year.

A Longer-Lasting HVAC System

Your HVAC system is a valuable investment with a limited lifetime. Depending on use, with regular maintenance you can expect your furnace and air conditioner to perform between 8-18 years before you will need to replace the old one. However, poor maintenance is one of the primary reasons for premature replacement HVAC systems prior to end of average life expectancy.
