Why Do You Need A Furnace Tune-Up?

Updated 2/27/19

A scheduled check-up for your furnace is probably at the bottom of your to-do list. However, as we approach the frostier months, now is the ideal time to guarantee your furnace is ready to provide you maximum comfort throughout the winter months.

Among the leading ways to prevent a breakdown and make sure it runs efficiently is with yearly scheduled tune-ups on your furnace. Just like most 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. In addition, regular cleanings can help pinpoint going concerns before they become big problems and you end up cashing out for emergency rates on a cold winter night. Additionally, because furnaces burn fuel to heat things up, it’s important to inspect all the various pieces 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 necessitate yearly HVAC maintenance to remain 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 malfunction in the middle of extreme temperatures. Be sure to get all you can from your warranty by making sure it stays valid as long as possible with yearly furnace system tune-ups from Knochelmann .

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 cause a number of comfort problems for homeowners, including:

operating
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 buy 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 designed to be used.

2. Double check your thermostat.

One of the easiest 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 swapped out your thermostat’s battery, now is the ideal time to do that.
When first going over to your heat setting, turn your thermostat up a few extra degrees to make certain 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 boost your savings by shutting the vents (supply registers) in rooms that aren’t being utilized. 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 cause failed blower motors, mold or mildew in your air ducts, damage to the compressor, a cracked heat exchanger, and other problems.

Full inspection. The service should include a full visual and point examination 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 operating parts. Your system 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 if needed to reestablish these elements to the designed specifications.
Filter replacement. A comprehensive furnace tune-up should include a common 1” filter replacement with your service. Typically, furnace filters need to be swapped out at least every three months, which can boost efficiency and prevent operational complications.
Written assessment. Quality HVAC companies always will give you their analysis in writing or on the receipt with your tune-up, including their professional maintenance suggestions for the next 12 months. This valuable information can help you figure out the current condition of your furnace and outline ways to lower your energy bills.

4. Is your Furnace Receiving Electricity?

Switch the thermostat to “on” from “auto” to force the fan to turn on. If the fan does come on, power is working correctly, but if it doesn’t, your furnace might not be receiving power.

5. Is the Furnace Switch Working Properly?

Each furnace has a power switch (similar to a light switch) either on the furnace or on a wall close by. Flip the switch and wait two 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 on a daily basis. If drain lines get clogged, the furnace will shut down.

7. Assess Vents for Blockage

If you have a furnace that vents out the side of the house, assess the situation 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 routine 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 serious problem. A tune-up alone will sometimes 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. An overworked HVAC system must work much harder to heat and cool your home, while a furnace or air conditioner that has been finely tuned can take less energy to provide exceptional 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 a valuable investment with a limited lifetime. Depending on use, with professional 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 prior to end of average life expectancy.
