Why Do You Need A Furnace Tune-Up?

Updated 2/27/19 
 
A pre-emptive 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 best time to ensure your furnace is ready to provide you maximum comfort throughout the winter months.

Among the leading ways to prevent a breakdown and make sure it runs as it should is with yearly scheduled tune-ups on your furnace. Just like any mechanical equipment, the life of a furnace will be extended with preventive maintenance, by ensuring that all the elements of the unit are running efficiently. Also, regular cleanings can help pinpoint going concerns before they become big problems and you end up breaking into your piggybank for emergency rates on a cold winter night. Plus, because furnaces burn fuel to heat things up, it’s important to take a look at all the various components to ensure there aren’t any cracks or leaks that could impact the safety of your household. 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 neglecting your tune-ups can sometimes result in losing your heating or AC system warranty, which can be major money if your system does ever breakdown 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 Neal Harris 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 written off, but their importance to your home’s furnace efficiency cannot be overstated. Filthy air filters can cause a number of comfort problems for homeowners, including:
  • running
  • Restricted airflow
  • Lower efficiency
  • Bigger 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 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 changed. Check the filter packaging to see how long the new air filter is intended to be used.

2. Double check your thermostat.
  • One of the simplest 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 greater than the current indoor temperature.
  • If you can’t remember the last time you replaced your thermostat’s battery, now is the perfect time to do so.
  • When first moving over to your heat setting, turn your thermostat up a few extra degrees to make sure that it is working 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 all of them, as doing so can actually increase the pressure in your furnace, making it work harder to heat your home. This can lead to broken blower motors, mold or mildew in your ductwork, 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. 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 equipment 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 if needed to return these elements to OEM specifications.
  • Filter replacement. A comprehensive furnace tune-up should include a normal 1” filter replacement with your service. Many furnace filters need to be replaced at least every 90 days, which can improve efficiency and prevent operational glitches.
  • Written assessment. Credible HVAC companies will also give you their analysis in writing or on the receipt with your tune-up, including their professional maintenance suggestions for the next year. This valuable information can help you determine the current condition of your furnace and what can be done to 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 does come on, power is working properly, but if it doesn’t, your furnace could be lacking power.

5. Is the Furnace Switch Functioning Properly?


Every furnace includes a power switch (similar to 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 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 the drain lines are clogged with dirt and debris, the furnace will shut down.

7. Examine Vents for Blockage


If your furnace vents out the side of the house, check to see if anything could be blocking the intake or exhaust. Be sure the area 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 help to reduce these factors. During your tune-up, your HVAC 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 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 equipment 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. An overworked HVAC system must work overtime to heat and cool your home, while a furnace or air conditioner that has been professionally 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 coming months.

A Longer-Lasting HVAC System

Your HVAC system is an expensive investment with a limited lifetime. Depending on use, with proper maintenance you can expect your furnace and air conditioner to last between 8-18 years before you will need to install a new one. However, poor maintenance is one of the primary 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 relax knowing it’s not going to force an early withdrawal you’re your 401k. Sometimes we have special offers in your local area that you can use to justify your next Starbucks run.

It’s better to take action now and be prepared than to regret it during the middle of winter when your furnace isn’t working. If you would like to learn more about what a furnace tune-up includes, or how it benefits you—give our experts a call at 866-397-3787 or schedule an appointment online.
