Why Do You Need A Furnace Tune-Up?

Updated 2/27/19 
 
A regular check-up for your furnace is about as exciting as it sounds. However, as we approach the frostier months, now is the smartest time to make sure your furnace is ready to provide you maximum comfort throughout the 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 most 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. Also, 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. Also, because furnaces burn fuel to make it hot, it’s important to examine all the various components 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 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 my furnace serviced?


Most manufacturers’ warranties require annual equipment maintenance to remain valid, so missing your tune-ups can actually result in losing your heating system warranty, which can be major money if your equipment does ever stop working in the middle of winter. Be sure to get all you can from your warranty by keeping it valid as long as possible with yearly furnace system tune-ups from Freschi 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 overlooked, but their importance to your home’s furnace efficiency cannot be overstated. Dirty air filters can mean a number of comfort annoyances for homeowners, including:
  • running
  • Restricted airflow
  • Lower efficiency
  • Higher 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 probably been a while since your last heating service, and likely time to swap it out. 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. 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 keep an eye on the thermostat.
  • Make certain 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 changed your thermostat’s battery, now is the perfect time to do so.
  • When first switching over to your heat setting, turn your thermostat up a few extra degrees to make certain that it is working as it should be 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 result in failed blower motors, mold or mildew in your air ducts, 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 eliminate friction between the moving parts. Your furnace 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 manufacturer specifications.
  • Filter replacement. A comprehensive furnace tune-up should include a normal 1” filter replacement with your service. Most furnace filters need to be replaced at least every 90 days, which can improve efficiency and prevent operational glitches.
  • 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 proposal for the coming year. This insightful information can help you figure out the current condition of your furnace and outline ways to lower your energy bills.

4. Is the Furnace Getting Electricity?

Shift the thermostat to “on” from “auto” to force the fan to turn on. If the fan does come on, power is working right, but if it doesn’t, your furnace may not be getting power.

5. Is the Furnace Switch Functioning Properly?


Each furnace has a power switch (similar to 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 drain lines get clogged, the furnace will shut down.

7. Examine Vents for Blockage


If you have a furnace that vents out the side of the house, check to see 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 several reasons, 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 corrosion. 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 home because your HVAC unit 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. A poorly-maintained HVAC system must work more to heat and cool your home, while a furnace or air conditioner that has been professionally tuned can take less energy to maintain 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 a valuable investment with a limited lifetime. Depending on use, with proper 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 primary reasons for early replacement HVAC systems prior to end of average life expectancy.

If you’re wondering how much a furnace tune up costs, you can rest easy 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.
