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 frostier months, now is the best time to ensure 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 enhanced 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 examine 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 if it looks like it’s working just fine, 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 call for yearly equipment maintenance to remain valid, so neglecting your tune-ups can sometimes result in losing your heating system warranty, which can be major money if your system does ever malfunction in the middle of a cold snap. Always get all you can from your warranty by making sure it stays valid as long as possible with annual furnace system tune-ups from Church Services.

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. Dusty air filters can mean a host of comfort issues for homeowners, including:
  • operating
  • Restricted airflow
  • Reduced efficiency
  • Bigger 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 probably 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 swapped out. 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 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 greater than the current indoor temperature.
  • If you can’t remember the last time you changed your thermostat’s battery, now is the best time to do that.
  • When first moving over to your heat setting, turn your thermostat up a few extra degrees to make certain that it is working correctly 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 utilized. 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 result in broken blower motors, mold or mildew in your ducts, 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 prevent friction between the moving 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 as needed to restore these elements to manufacturer specifications.
  • Filter replacement. A comprehensive furnace tune-up should include a common 1” filter replacement with your service. Most furnace filters need to be changed at least every three months, which can improve efficiency and prevent operational complications.
  • Written assessment. Quality 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 12 months. This valuable information can help you determine the current condition of your furnace and what can be done to 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 comes on, power is working correctly, but if it doesn’t, your furnace may not be getting power.

5. Is the Furnace Switch Working Properly?


All furnaces have a power switch (that resembles a light switch) either on the furnace or on a wall close by. Flip the switch and wait a few minutes to see if the furnace starts working. 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 each 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. Make sure 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 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 control 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 may instantly improve energy efficiency by up to 30%. You’ll also enjoy cleaner air and a cleaner residence 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 decreased 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 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 last 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.
