Why Do You Need A Furnace Tune- Up?

A regular 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 make sure 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 as it should is with yearly scheduled tune-ups on your furnace. Just like any mechanical equipment, the working life of a furnace will be extended with preventive maintenance, by ensuring that all the elements of the unit are working efficiently. Also, regular cleanings can help pinpoint issues before they become big problems and you end up paying emergency rates on a cold winter night. Plus, 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 household. 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 require yearly HVAC maintenance to stay valid, so neglecting your tune-ups can sometimes result in losing your heating system warranty, which can be major money if your furnace does ever malfunction in the middle of winter. Make sure you get all you can from your warranty by making sure it stays valid as long as possible with routine furnace system tune-ups from Norrell Service Experts.

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 forgotten, but their importance to your home’s furnace efficiency cannot be overstated. Filthy air filters can lead to a variety of comfort annoyances for homeowners, including:
  • working
  • Restricted airflow
  • Lower efficiency
  • Higher 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 get a new one. If it’s a simple disposable air filter, just buy 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. Read the filter packaging to see how long the new air filter is supposed to be used.

2. Double check your thermostat.
  • One of the most basic tasks that homeowners can do is check 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 swapped out your thermostat’s battery, now is the ideal time to do that.
  • When first moving 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 boost 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 ductwork, damage to the compressor, a ruptured heat exchanger, and other problems. What Does a Furnace Tune-Up Include?
  • Full inspection. The service should include a full visual and point inspection 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 reduce friction between the operating parts. Your equipment tune-up should include a complete lubrication.
  • Pilot and gas pressure evaluation. As part of your tune-up, changes may be made to the pilot and gas pressure if needed to restore these elements to their original specifications.
  • Filter replacement. A comprehensive furnace tune-up should include a normal 1” filter replacement with your service. Many furnace filters need to be swapped out at least every 90 days, which can boost efficiency and prevent operational problems.
  • Written assessment. Professional HVAC companies always will give you their analysis in writing or on the receipt with your tune-up, including their professional maintenance recommendations for the next 12 months. This valuable information can help you establish the current condition of your furnace and what can be done to lower your energy bills.

4. Does the Furnace Have Electricity?

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

5. Is the Furnace Switch Working Properly?


Every furnace includes a power switch (similar to a light switch) either on the furnace or on a nearby wall. Flip the switch and wait two minutes to see if it turns the furnace on. 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 each 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. Be sure the space is clear of 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 virtually eliminate these factors. During your tune-up, your HVAC technician will clean and check over your heating equipment, identifying areas of wear and tear. 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 home 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 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 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 coming months.

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 perform 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 before end of average life expectancy.
