Why Do You Need A Furnace Tune-Up?
Updated 2/27/19
A pre-emptive check-up for your furnace is probably at the bottom of your to-do list. However, as we approach the colder months, now is the ideal time to ensure your furnace is ready to provide you maximum comfort throughout the winter months.
Among the leading ways to prevent a breakdown and make sure it runs like a lean machine is with yearly scheduled tune-ups on your furnace. Just like any mechanical equipment, the life of a furnace will be extended with preventive maintenance, by ensuring that all the elements of the unit are working efficiently. Plus, 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 provide the heat, it’s important to take a look at all the various components to ensure there aren’t any cracks or leaks that could impact the safety of your family. 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 necessitate annual system 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 stop working in the middle of winter. Make sure you get all you can from your warranty by ensuring it’s valid as long as possible with yearly furnace system tune-ups from Winnipeg Supply 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 overprovinced. Filthy air filters can cause a variety of comfort problems 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 replace it. 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 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 swapped out your thermostat’s battery, now is the ideal time to do it.
- When first moving over to your heat setting, turn your thermostat up a few extra degrees to make sure that it is running correctly 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 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 reduce friction between the moving 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 when needed to restore these elements to OEM specifications.
- Filter replacement. A comprehensive furnace tune-up should include a standard 1” filter replacement with your service. Typically, furnace filters need to be replaced at least every 90 days, which can enhance efficiency and prevent operational glitches.
- Written assessment. Professional HVAC companies will also 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 determine the current condition of your furnace and how you can lower your energy bills.
4. Is your Furnace Receiving Electricity?
Switch the thermostat to “on” from “auto” to force the fan to turn on. If the fan does come on, power is working right, but if it doesn’t, your furnace might not be receiving power.
5. Is the Furnace Switch Functioning Properly?
Every furnace includes 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 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. Assess Vents for Blockage
If your furnace vents out the side of the house, assess the situation to see if anything could be blocking the intake or exhaust. Be sure the area 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 regular professional tune-ups can virtually eliminate these factors. During your tune-up, your HVAC technician will clean and check over your furnace, identifying areas of corrosion. They can identify failing parts in need of replacement before they become a bigger problem. A tune-up alone may instantly improve energy efficiency by up to 30%. You’ll also enjoy cleaner air and a cleaner house because your HVAC unit will be distributing clean air through a clean air filter. Perhaps one of the greatest benefits you’ll enjoy following a fall furnace or AC tune-up is lower utility bills. A neglected HVAC system must work more to heat and cool your home, while a furnace or air conditioner that has been expertly 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 a valuable investment with a limited lifetime. Depending on use, with regular 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 main reasons for early replacement HVAC systems before end of average life expectancy.
