Why Do You Need A Furnace Tune- Up?

A scheduled check-up for your furnace isn’t always top of mind or convenient. 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 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 any mechanical equipment, the life of a furnace will be extended 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. Plus, because furnaces burn fuel to heat things up, it’s important to inspect all the various components to ensure there aren’t any splits or leaks that could impact the safety of your family. 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 necessitate annual HVAC maintenance to remain valid, so neglecting your tune-ups can sometimes result in losing your heating or AC system warranty, which can be major money if your system does ever stop working in the middle of extreme temperatures. Make sure you get all you can from your warranty by ensuring it’s valid as long as possible with routine furnace system tune-ups from Boehmers/Cronin Emery 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. Filthy air filters can cause a variety of comfort problems for homeowners, including:
  • running
  • Restricted airflow
  • Decreased efficiency
  • Higher energy bills
If you remove your home’s air filter, hold it up to a light. If you can’t see light coming through it, it’s most 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 swapped out. Read the filter packaging to see how long the new air filter is supposed to be used.

2. Double check your thermostat.
  • One of the easiest tasks that homeowners can do is check 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 ideal time to do so.
  • When first going over to your heat setting, turn your thermostat up a few extra degrees to make sure 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 boost your savings by shutting the vents (supply registers) in rooms that aren’t being occupied. Resist the urge to close too many, 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 ductwork, damage to the compressor, a burst heat exchanger, and other problems. What Does a Furnace Tune-Up Include?
  • 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 reduce friction between the operating parts. Your equipment tune-up should include a complete lubrication.
  • Pilot and gas pressure regulating. As part of your tune-up, corrections may be made to the pilot and gas pressure when needed to reestablish these elements to their original 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 90 days, which can enhance efficiency and prevent operational problems.
  • 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 next year. This insightful 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?

Change the thermostat to “on” from “auto” to force the fan to function. If the fan turns on, power is working properly, but if it doesn’t, your furnace might not be receiving power.

5. Is the Furnace Switch Functioning Properly?


Every furnace includes a power switch (just like a light switch) either on the furnace or on a wall close by. Flip the switch and wait two 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 are clogged with dirt and debris, the furnace will shut down.

7. Check Vents for Blockage


If you have a furnace that vents out the side of the house, assess the situation to see if anything could be blocking the intake or exhaust. Confirm the space 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 many factors, 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 HVAC 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 serious problem. A tune-up alone could 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. An overworked HVAC system must work much harder to heat and cool your home, while a furnace or air conditioner that has been expertly 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 during the coldest months of the year.

A Longer-Lasting HVAC System

Your HVAC system is an expensive investment with a limited lifetime. Depending on use, with regular maintenance you can expect your furnace and air conditioner to run between 8-18 years before you will need to consider replacement. 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 force an early withdrawal you’re your 401k. Sometimes we have special offers in your local area that you can take advantage of.

It’s preferable to take action now and be prepared than to regret it during the middle of winter when your furnace gives up with a sad cough.
