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 colder months, now is the smartest 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 as it should is with yearly scheduled tune-ups on your furnace. Just like all mechanical equipment, the life of a furnace will be prolonged with preventive maintenance, by ensuring that all the elements of the unit are running efficiently. In addition, 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. Additionally, because furnaces burn fuel to make it hot, it’s important to take a look at all the various pieces 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 yearly system maintenance to keep valid, so missing your tune-ups can possibly result in losing your furnace warranty, which can be major money if your furnace does ever stop working in the middle of extreme temperatures. Make sure you get all you can from your warranty by keeping it valid as long as possible with annual furnace system tune-ups from Bryant Heating & Cooling 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. Dusty air filters can cause a number of comfort issues for homeowners, including:
  • working
  • 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 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 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 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 easiest tasks that homeowners can do is keep an eye on the thermostat.
  • Make sure 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 that.
  • When first going over to your heat setting, turn your thermostat up a few extra degrees to make sure that it is operating correctly and heating your home’s air.
3. Open up your air vents.

There’s a common misconception that you can increase your savings by shutting the vents (supply registers) in rooms that aren’t being utilized. 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 lead to 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 inspection 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 prevent friction between the operating 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 if needed to reestablish these elements to their original specifications.
  • Filter replacement. A comprehensive furnace tune-up should include a common 1” filter replacement with your service. Most furnace filters need to be changed at least every three months, which can improve 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 proposal for the next year. This valuable information can help you establish the current condition of your furnace and how you can 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 right, but if it doesn’t, your furnace may not be getting power.

5. Is the Furnace Switch Functioning Properly?


All furnaces have a power switch (just like 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 turns 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 drain lines get clogged, the furnace will shut down.

7. Examine Vents for Blockage


If your furnace vents out the side of the house, examine if anything could be blocking the intake or exhaust. Confirm the space isn’t obstructed by 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 annual professional tune-ups can control these factors. During your tune-up, your expert 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 bigger problem. A tune-up alone could 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 best benefits you’ll enjoy following a fall furnace or AC tune-up is lower utility bills. A neglected 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 operates more efficiently, it will deliver superior heating at lower cost than you otherwise may have had through the winter season.

A Longer-Lasting HVAC System

Your HVAC system is an important appliance with a limited lifetime. Depending on use, with professional maintenance you can expect your furnace and air conditioner to run between 8-18 years before you will need to consider replacement. However, poor maintenance is one of the top reasons for premature replacement HVAC systems before end of average life expectancy.
