Why Do You Need A Furnace Tune-Up?
Updated 2/27/19
A scheduled 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 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 most 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 concerns before they become big problems and you end up cashing out for emergency rates on a cold winter night. Additionally, because furnaces burn fuel to provide the heat, it’s important to take a look at all the various components 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 your system appears to be functioning properly, 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 annual HVAC maintenance to remain valid, so skipping your tune-ups can sometimes result in losing your heating system warranty, which can be major money if your furnace does ever breakdown in the middle of a cold snap. Be sure to 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.

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 lead to a variety of comfort annoyances for homeowners, including:
- working
- Restricted airflow
- Reduced efficiency
- Higher energy bills
2. Double check your thermostat.
- One of the most basic tasks that homeowners can do is take a look at the thermostat.
- Ensure 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 perfect time to do so.
- When first moving over to your heat setting, turn your thermostat up a few extra degrees to make certain that it is running correctly and heating your home’s air.
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 cause broken blower motors, mold or mildew in your ductwork, damage to the compressor, a ruptured 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. 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 eliminate 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 return these elements to their original specifications.
- Filter replacement. A comprehensive furnace tune-up should include a standard 1” filter replacement with your service. Many furnace filters need to be swapped out at least every three months, which can improve 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 how you can lower your energy bills.
4. Is the Furnace Getting Electricity?
Switch the thermostat to “on” from “auto” to force the fan to operate. If the fan turns on, power is working properly, but if it doesn’t, your furnace might not be receiving power.
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 the furnace starts working. Also check to see if all access panels and doors on the furnace are completely closed.
High-efficiency furnaces can drain off several gallons of water every day. If the drain lines are clogged with dirt and debris, the furnace will shut down.
If you have a furnace that vents out the side of the house, examine if anything could be blocking the intake or exhaust. Be sure the area 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 several reasons, 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 help to reduce these factors. During your tune-up, your maintenance 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 bigger problem. A tune-up alone could instantly improve energy efficiency by up to 30%. You’ll also enjoy cleaner air and a cleaner home because your HVAC unit 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. 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 coming months.
A Longer-Lasting HVAC System
Your HVAC system is a valuable 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 install a new one. However, poor maintenance is one of the primary reasons for earlier replacement HVAC systems prior to end of average life expectancy.
