Why Do You Need A Furnace Tune- Up?

A regular check-up for your furnace is about as exciting as it sounds. However, as we approach the less-popular winter months, now is the smartest time to ensure 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 as it should is with yearly scheduled tune-ups on your furnace. Just like most mechanical equipment, the useful life of a furnace will be prolonged with preventive maintenance, by ensuring that all the elements of the unit are working efficiently. Plus, 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 heat things up, it’s important to examine all the various components 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 tune ups?


Most manufacturers’ warranties require yearly equipment maintenance to keep valid, so skipping your tune-ups can possibly result in losing your heating or AC system warranty, which can be major money if your system does ever malfunction in the middle of a cold snap. Be sure to get all you can from your warranty by keeping it valid as long as possible with yearly furnace system tune-ups from Levy & Son Service Experts.

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


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 written off, but their importance to your home’s furnace efficiency cannot be overstated. Filthy air filters can lead to a number of comfort issues for homeowners, including:
  • running
  • Restricted airflow
  • Decreased efficiency
  • Increased 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 probably been a while since your last heating service, and likely time to swap it out. If it’s a simple disposable air filter, just replace it with 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. Read the filter packaging to see how long the new air filter is intended to be used.

2. Double check your thermostat.
  • One of the most basic 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 greater than the current indoor temperature.
  • If you can’t remember the last time you changed your thermostat’s battery, now is the perfect time to do so.
  • When first switching over to your heat setting, turn your thermostat up a few extra degrees to make certain that it is operating properly 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 result in failed blower motors, mold or mildew in your air ducts, damage to the compressor, a ruptured heat exchanger, and other problems. What Does a Furnace Tune-Up Include?
  • Full inspection. The service should include a full visual and point inspection 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 reduce friction between the moving parts. Your equipment 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 when needed to reestablish these elements to OEM specifications.
  • Filter replacement. A comprehensive furnace tune-up should include a common 1” filter replacement with your service. Most furnace filters need to be changed at least every 90 days, which can improve efficiency and prevent operational problems.
  • Written assessment. Professional HVAC companies always will give you their analysis in writing or on the receipt with your tune-up, including their professional maintenance suggestions for the next year. This insightful information can help you determine the current condition of your furnace and outline ways to lower your energy bills.

4. Is the Furnace Getting Electricity?

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

5. Is the Furnace Switch Working Properly?


Each furnace has a power switch (similar to a light switch) either on the furnace or on a wall close by. 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 each day. 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. Be sure the space 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 several reasons, 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 control these factors. During your tune-up, your expert 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 house because your HVAC system will be distributing clean air through a clean air filter. Perhaps one of the largest benefits you’ll enjoy following a fall furnace or AC tune-up is lower 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 professionally 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 through the winter season.

A Longer-Lasting HVAC System

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

If you’re wondering how much a furnace tune up costs, you can breathe a healthy sigh of relief knowing it’s not going to cost a limb. Often we have special offers in your local area that you can use to justify your next Starbucks run.
