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 best time to make sure your furnace is ready to provide you maximum comfort throughout the season.

Among the leading ways to stop your furnace from going on strike and make sure it runs as it should is with yearly scheduled tune-ups on your furnace. Just like any mechanical equipment, the useful life of a furnace will be enhanced with preventive maintenance, by ensuring that all the elements of the unit are working efficiently. Plus, 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 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 call for annual equipment maintenance to stay valid, so neglecting your tune-ups can possibly result in losing your furnace warranty, which can be major money if your system does ever stop working in the middle of winter. Be sure to get all you can from your warranty by ensuring it’s valid as long as possible with annual furnace system tune-ups from Coastal 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 forgotten, but their importance to your home’s furnace efficiency cannot be overstated. Dirty air filters can cause a host of comfort problems for homeowners, including:

operating
Restricted airflow
Reduced efficiency
Higher energy bills

If you pull out your home’s air filter, hold it up to a light. If you can’t see light coming through it, it’s more than likely been a while since your last heating service, and likely time to swap it out. 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 designed 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.
Ensure it is set to Heat and not Cool, and that the temperature setting is higher than the current indoor temperature.
If you can’t remember the last time you replaced your thermostat’s battery, now is the perfect time to do that.
When first switching over to your heat setting, turn your thermostat up a few extra degrees to make sure that it is running as it should be and heating your home’s air.

3. Open up your air vents.

There’s a common misconception that you can increase 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 lead to busted blower motors, mold or mildew in your ducts, damage to the compressor, a burst 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. 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 functioning parts. Your system tune-up should include a complete lubrication.
Pilot and gas pressure adjustment. 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 normal 1” filter replacement with your service. Many furnace filters need to be replaced at least every three months, which can improve efficiency and prevent operational glitches.
Written assessment. Credible HVAC companies always will give you their analysis in writing or on the receipt with your tune-up, including their professional maintenance suggestions for the next 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. Is the Furnace Getting Electricity?

Change 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 may not be getting power.

5. Is the Furnace Switch Functioning Properly?

Each furnace has a power switch (that resembles a light switch) either on the furnace or on a nearby wall. Flip the switch and wait a few 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 each day. If the drain lines are clogged with dirt and debris, 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 surrounding region 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 a variety of issues, 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 control these factors. During your tune-up, your expert technician will clean and check over your furnace, 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 will sometimes 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 diminished 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 will function more efficiently, it will deliver superior heating at lower cost than you otherwise may have had during the coldest months of the year.

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 last between 8-18 years before you will need to install a new one. However, poor maintenance is one of the primary reasons for premature replacement HVAC systems prior to end of average life expectancy.
