Why Do You Need A Furnace Tune-Up?

Updated 2/27/19 
 
A scheduled check-up for your furnace is about as exciting as it sounds. 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 reduce furnace breakdowns and make sure it runs efficiently is with yearly scheduled tune-ups on your furnace. Just like all mechanical equipment, the useful life of a furnace will be prolonged with preventive maintenance, by ensuring that all the elements of the unit are performing efficiently. Also, regular cleanings can help pinpoint concerns before they become big problems and you end up paying emergency rates on a cold winter night. Additionally, because furnaces burn fuel to make it hot, it’s important to take a look at all the various components to ensure there aren’t any splits or leaks that could impact the safety of your home. 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 call for routine HVAC maintenance to keep valid, so neglecting your tune-ups can sometimes result in losing your heating or AC system warranty, which can be major money if your system does ever stop working 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 Aramendia Plumbing.

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. Filthy air filters can mean a variety of comfort annoyances for homeowners, including:
  • running
  • Restricted airflow
  • Decreased efficiency
  • Higher 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 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 replaced. Read the filter packaging to see how long the new air filter is supposed to be used.

2. Double check your thermostat.
  • One of the simplest tasks that homeowners can do is check the thermostat.
  • Make certain it is set to Heat and not Cool, and that the temperature setting is higher than the current indoor temperature.
  • If you can’t remember the last time you swapped out 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 operating as it should be and heating your home’s air.
3. Open up your air vents.

There’s a common misconception that you can increase your savings 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 ductwork, damage to the compressor, a cracked 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. 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 operating parts. Your equipment 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 if needed to reestablish these elements to manufacturer 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 90 days, which can enhance efficiency and prevent operational glitches.
  • Written assessment. Credible HVAC companies always will 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 determine the current condition of your furnace and what can be done to lower your energy bills.

4. Does the Furnace Have Electricity?

Switch the thermostat to “on” from “auto” to force the fan to operate. If the fan does come on, power is working right, but if it doesn’t, your furnace could be lacking power.

5. Is the Furnace Switch Functioning 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 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 each day. If the drain lines are clogged with dirt and debris, the furnace will shut down.

7. Assess 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. Confirm 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 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 corrosion. They can identify failing parts in need of replacement before they become a serious problem. A tune-up alone could instantly improve energy efficiency by up to 30%. You’ll also enjoy cleaner air and a cleaner home because your HVAC system 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 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 coming months.

A Longer-Lasting HVAC System

Your HVAC system is an important appliance with a limited lifetime. Depending on use, with proper 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 main reasons for earlier replacement HVAC systems before end of average life expectancy.
