Why Do You Need A Furnace Tune- Up?

A regular check-up for your furnace isn’t always top of mind or convenient. 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 cold season.

Among the leading ways to prevent a breakdown and make sure it runs as it should is with yearly scheduled tune-ups on your furnace. Just like all mechanical equipment, the useful life of a furnace will be prolonged with preventive maintenance, by ensuring that all the elements of the unit are working efficiently. In addition, regular cleanings can help pinpoint concerns before they become big problems and you end up paying emergency rates on a cold winter night. Plus, because furnaces burn fuel to make it hot, it’s important to inspect all the various components to ensure there aren’t any ruptures or leaks that could impact the safety of your home. 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 tune ups?


Most manufacturers’ warranties require annual equipment maintenance to keep valid, so missing your tune-ups can sometimes result in losing your heating system warranty, which can be major money if your furnace does ever breakdown in the middle of winter. Make sure you get all you can from your warranty by making sure it stays valid as long as possible with yearly furnace system tune-ups from Falso Service Experts.

What can I do to troubleshoot my furnace before calling a tech?


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 host of comfort problems for homeowners, including:
  • operating
  • Restricted airflow
  • Lower efficiency
  • Bigger 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 replace it with 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. 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 above the current indoor temperature.
  • If you can’t remember the last time you swapped out 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 sure that it is working 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 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 broken blower motors, mold or mildew in your ductwork, damage to the compressor, a ruptured heat exchanger, and other problems. What Does a Furnace Tune-Up Include?
  • 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 moving parts. Your system 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 when needed to restore these elements to the designed specifications.
  • Filter replacement. A comprehensive furnace tune-up should include a common 1” filter replacement with your service. Many furnace filters need to be changed at least every 90 days, which can improve 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 proposal for the coming year. This important information can help you establish 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 function. If the fan does come on, power is working correctly, but if it doesn’t, your furnace might not be receiving power.

5. Is the Furnace Switch Operating Properly?


Every furnace includes a power switch (that resembles 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 it helps to turn the furnace on. 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 every day. If drain lines get clogged, the furnace will shut down.

7. Examine Vents for Blockage


If your furnace vents out the side of the house, check to see if anything could be blocking the intake or exhaust. Be sure the space 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 many factors, including dust and dirt, natural wear and tear, and buildup in drains or on burners. Keeping your heating system maintained with annual professional tune-ups can control these factors. During your tune-up, your maintenance 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 serious problem. A tune-up alone may 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 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 through the winter season.

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 top reasons for earlier replacement HVAC systems prior to end of average life expectancy.

If you’re wondering how much a furnace tune up costs, you can breathe a healthy sigh of relief knowing it’s not going to break the bank. Often we have special offers in your local area that you can use to justify your next Starbucks run.

It’s preferable to take action now and be prepared than to regret it during the coldsnap of the century when your furnace takes a dive.
