Why Do You Need A Furnace Tune- Up?

A scheduled check-up for your furnace is probably at the bottom of your to-do list. 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 stop your furnace from going on strike 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 extended with preventive maintenance, by ensuring that all the elements of the unit are performing efficiently. Also, regular cleanings can help pinpoint concerns 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 examine all the various pieces to ensure there aren’t any splits 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 missing your tune-ups can sometimes result in losing your heating system warranty, which can be major money if your system does ever malfunction in the middle of winter. Be sure to get all you can from your warranty by making sure it stays valid as long as possible with routine furnace system tune-ups from Stark Services.

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 overlooked, but their importance to your home’s furnace efficiency cannot be overstated. Dirty air filters can mean a number of comfort problems for homeowners, including:
  • running
  • Restricted airflow
  • Decreased efficiency
  • Higher energy bills
If you pull 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 get a new one. 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. Read the filter packaging to see how long the new air filter is supposed to be used.

2. Double check your thermostat.
  • One of the most basic tasks that homeowners can do is check the thermostat.
  • Make sure it is set to Heat and not Cool, and that the temperature setting is higher than 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 switching over to your heat setting, turn your thermostat up a few extra degrees to make certain that it is working 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 occupied. 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 lead to busted blower motors, mold or mildew in your ducts, damage to the compressor, a cracked heat exchanger, and other problems. What Does a Furnace Tune-Up Include?
  • Full inspection. The service should include a full visual and point review 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 moving parts. Your system 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 the designed specifications.
  • Filter replacement. A comprehensive furnace tune-up should include a common 1” filter replacement with your service. Many furnace filters need to be swapped out at least every third month, which can boost efficiency and prevent operational complications.
  • Written assessment. Credible HVAC companies should give you their analysis in writing or on the receipt with your tune-up, including their professional maintenance proposal for the coming year. This insightful information can help you determine the current condition of your furnace and how you can lower your energy bills.

4. Is the Furnace Getting Electricity?

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

5. Is the Furnace Switch Functioning Properly?


Each furnace has a power switch (that resembles 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 the furnace starts working. Also make sure 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. Check Vents for Blockage


If your home has a furnace that vents out the side of the house, examine if anything could be blocking the intake or exhaust. Confirm the area isn’t obstructed by 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 annual professional tune-ups can virtually eliminate these factors. During your tune-up, your maintenance technician will clean and check over your unit, identifying areas of concern. They can identify failing parts in need of replacement before they become a bigger 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 lower utility bills. A poorly-maintained 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 functions 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 an expensive investment with a limited lifetime. Depending on use, with professional 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 top reasons for earlier replacement HVAC systems prior to end of average life expectancy.
