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 less-popular winter months, now is the best time to ensure 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 efficiently is with yearly scheduled tune-ups on your furnace. Just like most mechanical equipment, the useful life of a furnace will be prolonged with preventive maintenance, by ensuring that all the elements of the unit are running efficiently. In addition, regular cleanings can help pinpoint issues before they become big problems and you end up cashing out for emergency rates on a cold winter night. Also, because furnaces burn fuel to provide the heat, it’s important to inspect all the various parts 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 tune ups?


Most manufacturers’ warranties require yearly equipment maintenance to stay valid, so skipping your tune-ups can possibly result in losing your heating or AC system warranty, which can be major money if your furnace does ever stop working in the middle of winter. Always get all you can from your warranty by ensuring it’s valid as long as possible with yearly furnace system tune-ups from Comfortech 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 overlooked, 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
  • Decreased efficiency
  • Increased energy bills
If you take 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 replace it. If it’s a simple disposable air filter, just get 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 designed to be used.

2. Double check your thermostat.
  • One of the simplest 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 replaced your thermostat’s battery, now is the ideal time to do so.
  • When first switching over to your heat setting, turn your thermostat up a few extra degrees to ensure that it is running 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 used. 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 result in broken blower motors, mold or mildew in your air ducts, damage to the compressor, a cracked 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 prevent friction between the moving parts. Your system 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 return these elements to the designed specifications.
  • Filter replacement. A comprehensive furnace tune-up should include a common 1” filter replacement with your service. Most furnace filters need to be replaced at least every three months, which can boost efficiency and prevent operational complications.
  • 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 recommendations for the next year. This insightful 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 operate. If the fan turns on, power is working right, but if it doesn’t, your furnace could be lacking power.

5. Is the Furnace Switch Operating Properly?


Each furnace has 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 your home has a furnace that vents out the side of the house, examine if anything could be blocking the intake or exhaust. Make 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 regular professional tune-ups can help to reduce these factors. During your tune-up, your HVAC 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 larger problem. A tune-up alone may 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 largest 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 expertly tuned can take less energy to guarantee indoor comfort. Because your heating system operates 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 regular maintenance you can expect your furnace and air conditioner to run 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 before end of average life expectancy.
