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 less-popular winter months, now is the smartest time to guarantee 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 most mechanical equipment, the working life of a furnace will be prolonged 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. Additionally, because furnaces burn fuel to heat things up, it’s important to inspect all the various components to ensure there aren’t any splits 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 annual HVAC maintenance to stay valid, so neglecting your tune-ups can possibly result in losing your heating system warranty, which can be major money if your equipment does ever breakdown in the middle of a cold snap. Be sure to 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 Heating & Air Conditioning.
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 lead to a variety of comfort annoyances for homeowners, including:
- operating
- 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 more than likely 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 replace it with 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 designed to be used.
2. Double check your thermostat.
- One of the easiest tasks that homeowners can do is take a look at the thermostat.
- Make sure 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 replaced 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 ensure that it is operating correctly 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 all of them, as doing so can actually increase the pressure in your furnace, making it work harder to heat your home. This can lead to failed blower motors, mold or mildew in your ductwork, 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 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, corrections may be made to the pilot and gas pressure as needed to reestablish these elements to OEM specifications.
- Filter replacement. A comprehensive furnace tune-up should include a normal 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 problems.
- Written assessment. Professional HVAC companies should give you their analysis in writing or on the receipt with your tune-up, including their professional maintenance suggestions for the coming year. This insightful 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 turn on. If the fan does come on, power is working properly, but if it doesn’t, your furnace may not be getting power.
5. Is the Furnace Switch Functioning Properly?
Every furnace includes a power switch (just like 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 helps to turn the furnace on. Also confirm that 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. 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. Be sure the surrounding region doesn’t have 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 routine professional tune-ups can help to reduce these factors. During your tune-up, your expert 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 house 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. A poorly-maintained HVAC system must work overtime 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 operates more efficiently, it will deliver superior heating at lower cost than you otherwise may have had through the winter season.
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 perform between 8-18 years before you will need to install a new one. However, poor maintenance is one of the primary reasons for earlier replacement HVAC systems ahead of end of average life expectancy.
