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 smartest time to make sure your furnace is ready to provide you maximum comfort throughout the winter months.

Among the leading ways to stop your furnace from going on strike and make sure it runs efficiently is with yearly scheduled tune-ups on your furnace. Just like all mechanical equipment, the working life of a furnace will be prolonged with preventive maintenance, by ensuring that all the elements of the unit are running efficiently. Also, regular cleanings can help pinpoint issues before they become big problems and you end up breaking into your piggybank for 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 parts to ensure there aren’t any cracks or leaks that could impact the safety of your home. 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 my furnace serviced?

Most manufacturers’ warranties require annual system maintenance to keep 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 malfunction 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 yearly furnace system tune-ups from Winnipeg Supply .

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. Dusty air filters can mean a host of comfort problems for homeowners, including:

working
Restricted airflow
Lower efficiency
Bigger energy bills

If you take out 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. Refer to 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 take a look at 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 changed your thermostat’s battery, now is the best time to do that.
When first going over to your heat setting, turn your thermostat up a few extra degrees to make certain that it is running 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 result in broken blower motors, mold or mildew in your ducts, damage to the compressor, a cracked heat exchanger, and other problems.

Full inspection. The service should include a full visual and point review 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 operating parts. Your system tune-up should include a complete lubrication.
Pilot and gas pressure evaluation. As part of your tune-up, adjustments should be made to the pilot and gas pressure if needed to return these elements to the designed specifications.
Filter replacement. A comprehensive furnace tune-up should include a common 1” filter replacement with your service. Most furnace filters need to be swapped out at least every 90 days, which can enhance efficiency and prevent operational problems.
Written assessment. Quality 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 figure out the current condition of your furnace and what can be done to lower your energy bills.

4. Does the Furnace Have Electricity?

Switch the thermostat to “on” from “auto” to force the fan to turn on. If the fan comes on, power is working right, but if it doesn’t, your furnace might not be receiving power.

5. Is the Furnace Switch Working Properly?

Every furnace includes a power switch (similar to a light switch) either on the furnace or located on a wall close to the furnace. Flip the switch and wait a few minutes to see if the furnace starts working. Also check to see if 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 home has 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 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 routine 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 corrosion. They can identify failing parts in need of replacement before they become a bigger problem. A tune-up alone will sometimes 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. An overworked HVAC system must work much harder to heat and cool your home, while a furnace or air conditioner that has been finely tuned can take less energy to provide exceptional indoor comfort. Because your heating system will function 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 important appliance 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 replace the old one. However, poor maintenance is one of the main reasons for earlier replacement HVAC systems before end of average life expectancy.
