Why Do You Need A Furnace Tune-Up?

Updated 2/27/19

A regular 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 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 like a lean machine 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 performing efficiently. In addition, regular cleanings can help pinpoint going 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 heat things up, it’s important to take a look at all the various pieces to ensure there aren’t any splits 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 require routine HVAC maintenance to remain valid, so skipping your tune-ups can possibly result in losing your heating or AC system warranty, which can be major money if your equipment does ever malfunction in the middle of extreme temperatures. Always get all you can from your warranty by making sure it stays valid as long as possible with yearly furnace system tune-ups from 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 overstated. Filthy air filters can cause a host of comfort annoyances for homeowners, including:

operating
Restricted airflow
Lower efficiency
Increased 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 get a new one. 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 replaced. Read the filter packaging to see how long the new air filter is designed to be used.

2. Double check your thermostat.

One of the simplest 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 higher 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 going over to your heat setting, turn your thermostat up a few extra degrees to make certain that it is operating properly 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 occupied. 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 failed 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 inspection 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 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 restore these elements to the designed specifications.
Filter replacement. A comprehensive furnace tune-up should include a standard 1” filter replacement with your service. Most furnace filters need to be replaced at least every three months, which can enhance efficiency and prevent operational problems.
Written assessment. Credible HVAC companies will also give you their analysis in writing or on the receipt with your tune-up, including their professional maintenance proposal for the next year. This valuable information can help you determine the current condition of your furnace and outline ways to lower your energy bills.

4. Does the Furnace Have Electricity?

Shift the thermostat to “on” from “auto” to force the fan to function. 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?

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 couple of minutes to see if it helps to turn the furnace on. 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 the drain lines aren’t clear and open, the furnace will shut down.

7. Check 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. Confirm 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 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 routine professional tune-ups can virtually eliminate 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 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 system 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 diminished utility bills. A poorly-maintained HVAC system must work more to heat and cool your home, while a furnace or air conditioner that has been professionally 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 an important appliance 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 replace the old one. However, poor maintenance is one of the primary reasons for premature replacement HVAC systems prior to end of average life expectancy.
