Why Do You Need A Furnace Tune-Up?

Updated 2/27/19

A scheduled check-up for your furnace isn’t always top of mind or convenient. However, as we approach the frostier months, now is the best time to guarantee your furnace is ready to provide you maximum comfort throughout the winter months.

Among the leading ways to reduce furnace breakdowns and make sure it runs efficiently is with yearly scheduled tune-ups on your furnace. Just like most mechanical equipment, the useful life of a furnace will be enhanced 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 cashing out for emergency rates on a cold winter night. Also, because furnaces burn fuel to make it hot, it’s important to examine all the various pieces to ensure there aren’t any ruptures or leaks that could impact the safety of your family. 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 routine equipment maintenance to remain valid, so missing your tune-ups can sometimes result in losing your furnace warranty, which can be major money if your furnace does ever malfunction in the middle of a cold snap. Always get all you can from your warranty by ensuring it’s valid as long as possible with routine furnace system tune-ups from Strand Brothers .

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 lead to a variety of comfort issues for homeowners, including:

running
Restricted airflow
Reduced efficiency
Increased 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 changed. Check 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 keep an eye on the thermostat.
Make sure 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 replaced your thermostat’s battery, now is the best 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 operating correctly and heating your home’s air.

3. Open up your air vents.

There’s a common misconception that you can save money by shutting the vents (supply registers) in rooms that aren’t being used. 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 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 examination to check all the working parts of your furnace and duct system. A qualified technician should be able to let you know if your equipment or individual parts are showing signs of wear during this review.
Lubrication. Mechanical equipment needs lubrication to reduce friction between the operating parts. Your system tune-up should include a complete lubrication.
Pilot and gas pressure adjustment. As part of your tune-up, changes may be made to the pilot and gas pressure if needed to reestablish 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 changed at least every three months, which can improve efficiency and prevent operational complications.
Written assessment. Professional 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 important information can help you determine the current condition of your furnace and what can be done to lower your energy bills.

4. Is the Furnace Getting Electricity?

Switch the thermostat to “on” from “auto” to force the fan to function. 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 Operating Properly?

All furnaces have a power switch (that resembles a light switch) either on the furnace or on a wall close by. Flip the switch and wait a couple of minutes to see if the furnace starts working. 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 on a daily basis. If drain lines get clogged, the furnace will shut down.

7. Examine Vents for Blockage

If you have 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 surrounding region 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 unit, identifying areas of concern. They can identify failing parts in need of replacement before they become a serious 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 equipment 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 much harder 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 through the winter season.

A Longer-Lasting HVAC System

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