Why Do You Need A Furnace Tune- Up?

A scheduled check-up for your furnace is about as exciting as it sounds. However, as we approach the less-popular winter months, now is the best time to guarantee your furnace is ready to provide you maximum comfort throughout the season.

Among the leading ways to reduce furnace breakdowns and make sure it runs efficiently is with yearly scheduled tune-ups on your furnace. Just like most mechanical equipment, the working life of a furnace will be enhanced 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 breaking into your piggybank for emergency rates on a cold winter night. Additionally, because furnaces burn fuel to provide the heat, it’s important to examine all the various parts 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 if it looks like it’s working just fine, 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 call for annual equipment maintenance to stay valid, so missing your tune-ups can sometimes result in losing your furnace warranty, which can be major money if your system does ever malfunction in the middle of a cold snap. Always get all you can from your warranty by keeping it 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?


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 variety of comfort problems for homeowners, including:
  • operating
  • Restricted airflow
  • Reduced 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 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. Refer to the filter packaging to see how long the new air filter is designed to be used.

2. Double check your thermostat.
  • One of the most basic tasks that homeowners can do is keep an eye on the thermostat.
  • Make certain 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 ideal 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 running properly 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 used. 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 result in broken 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. This is the best method for the technician to notify you of any components that are beginning to show signs of wear.
  • Lubrication. Mechanical equipment needs lubrication to prevent friction between the operating parts. Your equipment 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 if needed to restore these elements to the designed specifications.
  • Filter replacement. A comprehensive furnace tune-up should include a standard 1” filter replacement with your service. Most furnace filters need to be changed at least every three months, which can boost efficiency and prevent operational glitches.
  • 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 recommendations 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. Does the Furnace Have Electricity?

Switch the thermostat to “on” from “auto” to force the fan to function. If the fan turns on, power is working right, but if it doesn’t, your furnace could be lacking 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 a few 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 drain lines get clogged, the furnace will shut down.

7. Check Vents for Blockage


If your furnace vents out the side of the house, assess the situation to see if anything could be blocking the intake or exhaust. Make 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 a variety of issues, 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 unit, identifying areas of concern. They can identify failing parts in need of replacement before they become a bigger problem. A tune-up alone will sometimes 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 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 finely tuned can take less energy to maintain 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 last between 8-18 years before you will need to install a new one. However, poor maintenance is one of the main reasons for early replacement HVAC systems before end of average life expectancy.
