Why Do You Need A Furnace Tune- Up?

A scheduled check-up for your furnace is about as exciting as it sounds. However, as we approach the colder months, now is the ideal time to guarantee your furnace is ready to provide you maximum comfort throughout the winter months.

Among the leading ways to stop your furnace from going on strike and make sure it runs like a lean machine is with yearly scheduled tune-ups on your furnace. Just like most mechanical equipment, the working life of a furnace will be prolonged with preventive maintenance, by ensuring that all the elements of the unit are working efficiently. Plus, 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. Plus, because furnaces burn fuel to heat things up, it’s important to take a look at all the various parts 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 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 routine equipment maintenance to stay valid, so skipping your tune-ups can sometimes result in losing your heating or AC system warranty, which can be major money if your equipment does ever stop working in the middle of extreme temperatures. Always get all you can from your warranty by ensuring it’s valid as long as possible with routine furnace system tune-ups from BW/Cook Service Experts Heating & Air Conditioning.

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 written off, but their importance to your home’s furnace efficiency cannot be overstated. Filthy air filters can cause a host of comfort problems for homeowners, including:
  • running
  • 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 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 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. Refer to the filter packaging to see how long the new air filter is intended to be used.

2. Double check your thermostat.
  • One of the easiest tasks that homeowners can do is check the thermostat.
  • Ensure it is set to Heat and not Cool, and that the temperature setting is greater 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 that.
  • When first going 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 boost your savings by shutting the vents (supply registers) in rooms that aren’t being utilized. 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 failed 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 inspection to check all the working parts of your furnace and duct system. This is the best method for the technician to notify you of any components that are beginning to show signs of wear.
  • Lubrication. Mechanical equipment needs lubrication to eliminate friction between the functioning parts. Your furnace tune-up should include a complete lubrication.
  • Pilot and gas pressure regulating. As part of your tune-up, changes may be made to the pilot and gas pressure as 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. Typically, furnace filters need to be replaced at least every three months, which can improve efficiency and prevent operational glitches.
  • Written assessment. Quality HVAC companies should give you their analysis in writing or on the receipt with your tune-up, including their professional maintenance proposal for the next year. This important information can help you establish the current condition of your furnace and how you can 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 could be lacking power.

5. Is the Furnace Switch Working 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 turns 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 the drain lines aren’t clear and open, the furnace will shut down.

7. Check 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. Confirm the area 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 virtually eliminate these factors. During your tune-up, your HVAC technician will clean and check over your furnace, 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 house because your HVAC equipment 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 lower utility bills. An overworked HVAC system must work more to heat and cool your home, while a furnace or air conditioner that has been expertly tuned can take less energy to provide exceptional 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 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 consider replacement. However, poor maintenance is one of the main reasons for early replacement HVAC systems ahead of end of average life expectancy.
