Why Do You Need A Furnace Tune-Up?

Updated 2/27/19 
 
A scheduled check-up for your furnace isn’t always top of mind or convenient. However, as we approach the frostier months, now is the ideal time to make sure your furnace is ready to provide you maximum comfort throughout the cold season.

Among the leading ways to reduce furnace breakdowns and make sure it runs as it should is with yearly scheduled tune-ups on your furnace. Just like all mechanical equipment, the life of a furnace will be enhanced with preventive maintenance, by ensuring that all the elements of the unit are running efficiently. Plus, regular cleanings can help pinpoint issues before they become big problems and you end up breaking into your piggybank for emergency rates on a cold winter night. Plus, because furnaces burn fuel to provide the heat, it’s important to examine all the various components to ensure there aren’t any cracks or leaks that could impact the safety of your family. 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 my furnace serviced?


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

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


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. Dirty air filters can mean a variety of comfort problems for homeowners, including:
  • working
  • Restricted airflow
  • Lower efficiency
  • Increased 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 get a new one. 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. Check 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 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 replaced your thermostat’s battery, now is the ideal time to do it.
  • When first going over to your heat setting, turn your thermostat up a few extra degrees to ensure that it is operating 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 them all, as doing so can actually increase the pressure in your furnace, making it work harder to heat your home. This can cause failed blower motors, mold or mildew in your ducts, damage to the compressor, a burst heat exchanger, and other problems.
  • 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 reduce friction between the moving parts. Your equipment tune-up should include a complete lubrication.
  • Pilot and gas pressure adjustment. As part of your tune-up, changes may be made to the pilot and gas pressure when needed to return these elements to their original specifications.
  • Filter replacement. A comprehensive furnace tune-up should include a standard 1” filter replacement with your service. Typically, furnace filters need to be changed at least every 90 days, which can boost efficiency and prevent operational glitches.
  • 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 coming year. This important information can help you determine the current condition of your furnace and how you can lower your energy bills.

4. Does the Furnace Have Electricity?

Switch the thermostat to “on” from “auto” to force the fan to turn on. 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?


All furnaces have a power switch (similar to a light switch) either on the furnace or on a wall close by. Flip the switch and wait a couple of 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 each day. If the drain lines are clogged with dirt and debris, the furnace will shut down.

7. Assess 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 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 help to reduce these factors. During your tune-up, your expert 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 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 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 decreased 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 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 last between 8-18 years before you will need to install a new one. However, poor maintenance is one of the primary reasons for early replacement HVAC systems ahead of end of average life expectancy.
