Why Do You Need A Furnace Tune-Up?

Updated 2/27/19 
 
A pre-emptive check-up for your furnace is about as exciting as it sounds. However, as we approach the frostier months, now is the ideal time to make sure your furnace is ready to provide you maximum comfort throughout the winter months.

Among the leading ways to stop your furnace from going on strike and make sure it runs as it should 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 running 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. Additionally, because furnaces burn fuel to make it hot, it’s important to inspect 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 annual equipment maintenance to stay valid, so missing your tune-ups can possibly result in losing your heating system warranty, which can be major money if your system does ever stop working in the middle of winter. Make sure you get all you can from your warranty by ensuring it’s valid as long as possible with routine furnace system tune-ups from Service Experts Heating & Air Conditioning.

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. Dirty air filters can lead to a variety of comfort problems for homeowners, including:
  • running
  • Restricted airflow
  • Lower efficiency
  • Increased energy bills
If you remove 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 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 replaced. 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 take a look at the thermostat.
  • Ensure 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 swapped out your thermostat’s battery, now is the perfect time to do that.
  • When first switching over to your heat setting, turn your thermostat up a few extra degrees to make sure 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 used. 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 air 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. 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 system tune-up should include a complete lubrication.
  • Pilot and gas pressure adjustment. As part of your tune-up, changes may be made to the pilot and gas pressure as needed to restore these elements to manufacturer 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 will also give you their analysis in writing or on the receipt with your tune-up, including their professional maintenance recommendations for the next 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?

Shift 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 may not be getting power.

5. Is the Furnace Switch Working Properly?


Each furnace has a power switch (just like a light switch) either on the furnace or on a nearby wall. Flip the switch and wait two minutes to see if the furnace starts working. 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. Assess Vents for Blockage


If your home has a furnace that vents out the side of the house, check to see if anything could be blocking the intake or exhaust. Confirm 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 many factors, including dust and dirt, natural wear and tear, and buildup in drains or on burners. Keeping your heating system maintained with regular professional tune-ups can help to reduce these factors. During your tune-up, your maintenance technician will clean and check over your furnace, identifying areas of concern. 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 unit 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 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 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 perform between 8-18 years before you will need to consider replacement. However, poor maintenance is one of the main reasons for early replacement HVAC systems prior to end of average life expectancy.

If you’re wondering how much a furnace tune up costs, you can rest easy knowing it’s not going to force an early withdrawal you’re your 401k. Frequently we have special offers in your local area that you can use to justify your next Starbucks run.
