Why Do You Need A Furnace Tune-Up?

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

Among the leading ways to reduce furnace breakdowns and make sure it runs like a lean machine is with yearly scheduled tune-ups on your furnace. Just like most mechanical equipment, the working life of a furnace will be prolonged with preventive maintenance, by ensuring that all the elements of the unit are running efficiently. Also, regular cleanings can help pinpoint issues before they become big problems and you end up paying emergency rates on a cold winter night. Plus, because furnaces burn fuel to provide the heat, it’s important to examine all the various parts to ensure there aren’t any cracks 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 necessitate yearly equipment maintenance to stay valid, so missing your tune-ups can actually result in losing your heating or AC system warranty, which can be major money if your system does ever malfunction in the middle of extreme temperatures. Always get all you can from your warranty by making sure it stays valid as long as possible with routine furnace system tune-ups from Service Experts.

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. Dusty air filters can cause a host of comfort issues for homeowners, including:
  • working
  • Restricted airflow
  • Lower 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 more than likely been a while since your last heating service, and likely time to swap it out. If it’s a simple disposable air filter, just buy 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 replaced. Refer to the filter packaging to see how long the new air filter is intended to be used.

2. Double check your thermostat.
  • One of the easiest tasks that homeowners can do is check the thermostat.
  • Make certain 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 swapped out your thermostat’s battery, now is the best time to do so.
  • When first going over to your heat setting, turn your thermostat up a few extra degrees to make certain that it is operating correctly and heating your home’s air.
3. Open up your air vents.

There’s a common misconception that you can save money 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 broken blower motors, mold or mildew in your air 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. An experienced service technician should be able to identify any concerns or signs of excessive wear during this review.
  • Lubrication. Mechanical equipment needs lubrication to prevent friction between the moving parts. Your furnace tune-up should include a complete lubrication.
  • Pilot and gas pressure evaluation. As part of your tune-up, changes may be made to the pilot and gas pressure when needed to return these elements to their original specifications.
  • Filter replacement. A comprehensive furnace tune-up should include a normal 1” filter replacement with your service. Typically, furnace filters need to be changed at least every three months, which can enhance efficiency and prevent operational problems.
  • Written assessment. Quality HVAC companies will also give you their analysis in writing or on the receipt with your tune-up, including their professional maintenance proposal for the next year. This insightful information can help you determine the current condition of your furnace and what can be done to lower your energy bills.

4. Is the Furnace Getting Electricity?

Switch the thermostat to “on” from “auto” to force the fan to operate. If the fan comes on, power is working right, but if it doesn’t, your furnace might not be receiving power.

5. Is the Furnace Switch Functioning Properly?


All furnaces have a power switch (just like a light switch) either on the furnace or located on a wall close to the furnace. Flip the switch and wait two minutes to see if it helps to turn the furnace on. Also check to see if all access panels and doors on the furnace are completely closed.

6. Condensate Drainage


High-efficiency furnaces can drain off several gallons of water on a daily basis. If the drain lines aren’t clear and open, the furnace will shut down.

7. Examine Vents for Blockage


If you have a furnace that vents out the side of the house, check to see if anything could be blocking the intake or exhaust. Confirm 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 many factors, including dust and dirt, natural wear and tear, and buildup in drains or on burners. Keeping your heating system maintained with routine professional tune-ups can control these factors. During your tune-up, your maintenance technician will clean and check over your furnace, identifying areas of wear and tear. They can identify failing parts in need of replacement before they become a larger problem. A tune-up alone may instantly improve energy efficiency by up to 30%. You’ll also enjoy cleaner air and a cleaner home because your HVAC unit will be distributing clean air through a clean air filter. Perhaps one of the best benefits you’ll enjoy following a fall furnace or AC tune-up is diminished utility bills. An overworked HVAC system must work more to heat and cool your home, while a furnace or air conditioner that has been finely tuned can take less energy to provide exceptional indoor comfort. Because your heating system operates more efficiently, it will deliver superior heating at lower cost than you otherwise may have had through the winter season.

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 install a new one. However, poor maintenance is one of the main reasons for premature replacement HVAC systems before end of average life expectancy.
