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 less-popular winter 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 efficiently is with yearly scheduled tune-ups on your furnace. Just like most mechanical equipment, the life of a furnace will be prolonged with preventive maintenance, by ensuring that all the elements of the unit are working efficiently. In addition, regular cleanings can help pinpoint concerns before they become big problems and you end up paying emergency rates on a cold winter night. Additionally, because furnaces burn fuel to heat things up, it’s important to take a look at all the various parts to ensure there aren’t any ruptures or leaks that could impact the safety of your home. 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 call for routine HVAC maintenance to keep 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 stop working 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 annual furnace system tune-ups from 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. Dirty air filters can mean a number of comfort issues for homeowners, including:
  • running
  • Restricted airflow
  • Lower 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 more than 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 replaced. Check the filter packaging to see how long the new air filter is supposed to be used.

2. Double check your thermostat.
  • One of the easiest 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 above 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 it.
  • When first going 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 boost your savings by shutting the vents (supply registers) in rooms that aren’t being occupied. 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 cause busted blower motors, mold or mildew in your air ducts, damage to the compressor, a burst heat exchanger, and other problems.
  • 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 reduce friction between the functioning parts. Your system tune-up should include a complete lubrication.
  • Pilot and gas pressure evaluation. As part of your tune-up, corrections may be made to the pilot and gas pressure as needed to reestablish these elements to their original specifications.
  • Filter replacement. A comprehensive furnace tune-up should include a standard 1” filter replacement with your service. Typically, furnace filters need to be swapped out at least every 90 days, which can enhance efficiency and prevent operational complications.
  • Written assessment. Quality HVAC companies should give you their analysis in writing or on the receipt with your tune-up, including their professional maintenance recommendations for the coming year. This valuable information can help you figure out the current condition of your furnace and outline ways to lower your energy bills.

4. Does the Furnace Have Electricity?

Shift the thermostat to “on” from “auto” to force the fan to function. 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 Working Properly?


All furnaces have 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 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 drain lines get clogged, 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. 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 several reasons, 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 maintenance technician will clean and check over your heating equipment, identifying areas of concern. They can identify failing parts in need of replacement before they become a serious problem. A tune-up alone may instantly improve energy efficiency by up to 30%. You’ll also enjoy cleaner air and a cleaner residence because your HVAC equipment 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 diminished utility bills. A poorly-maintained 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 provide exceptional 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 regular maintenance you can expect your furnace and air conditioner to last between 8-18 years before you will need to consider replacement. However, poor maintenance is one of the primary reasons for earlier replacement HVAC systems ahead of end of average life expectancy.
