Why Do You Need A Furnace Tune-Up?

Updated 2/27/19 
 
A regular 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 cold 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 all mechanical equipment, the useful life of a furnace will be extended with preventive maintenance, by ensuring that all the elements of the unit are working efficiently. In addition, regular cleanings can help pinpoint going concerns before they become big problems and you end up paying emergency rates on a cold winter night. Also, because furnaces burn fuel to heat things up, it’s important to examine all the various components to ensure there aren’t any splits 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 require yearly equipment maintenance to stay valid, so skipping your tune-ups can actually result in losing your heating or AC system warranty, which can be major money if your furnace does ever stop working in the middle of extreme temperatures. Be sure to get all you can from your warranty by ensuring it’s valid as long as possible with annual furnace system tune-ups from Robinson 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 overlooked, but their importance to your home’s furnace efficiency cannot be overstated. Filthy air filters can cause a variety of comfort issues for homeowners, including:
  • running
  • Restricted airflow
  • Reduced efficiency
  • Increased 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. Check the filter packaging to see how long the new air filter is designed to be used.

2. Double check your thermostat.
  • One of the easiest tasks that homeowners can do is check 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 replaced your thermostat’s battery, now is the best time to do that.
  • When first switching over to your heat setting, turn your thermostat up a few extra degrees to make certain 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 save money by shutting the vents (supply registers) in rooms that aren’t being used. Resist the urge to close them all, as doing so can actually increase the pressure in your furnace, making it work harder to heat your home. This can result in failed blower motors, mold or mildew in your air ducts, damage to the compressor, a cracked heat exchanger, and other problems.
  • Full inspection. The service should include a full visual and point examination 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 eliminate friction between the functioning parts. Your furnace 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 when 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. Typically, furnace filters need to be swapped out at least every 90 days, 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 recommendations for the coming year. This valuable information can help you determine the current condition of your furnace and outline ways to lower your energy bills.

4. Is the Furnace Getting Electricity?

Change the thermostat to “on” from “auto” to force the fan to operate. If the fan does come on, power is working properly, but if it doesn’t, your furnace may not be getting power.

5. Is the Furnace Switch Working Properly?


All furnaces have 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 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 you have a furnace that vents out the side of the house, check to see if anything could be blocking the intake or exhaust. Be sure 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 routine professional tune-ups can control these factors. During your tune-up, your expert 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 could instantly improve energy efficiency by up to 30%. You’ll also enjoy cleaner air and a cleaner residence 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 decreased utility bills. A poorly-maintained 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 guarantee 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 run between 8-18 years before you will need to install a new one. However, poor maintenance is one of the main reasons for earlier replacement HVAC systems prior to end of average life expectancy.
