Why Do You Need A Furnace Tune-Up?
Updated 2/27/19
A pre-emptive 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 guarantee your furnace is ready to provide you maximum comfort throughout the winter months.
Among the leading ways to stop your furnace from going on strike and make sure it runs as it should is with yearly scheduled tune-ups on your furnace. Just like all 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. Plus, regular cleanings can help pinpoint concerns before they become big problems and you end up breaking into your piggybank for emergency rates on a cold winter night. Additionally, because furnaces burn fuel to provide the heat, it’s important to take a look at all the various components to ensure there aren’t any ruptures or leaks that could impact the safety of your household. Taking the time to schedule a tune-up, even if it looks like it’s working just fine, 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 annual HVAC maintenance to keep valid, so missing your tune-ups can possibly result in losing your heating system warranty, which can be major money if your furnace does ever breakdown in the middle of a cold snap. Always get all you can from your warranty by keeping it valid as long as possible with annual 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. Dusty air filters can lead to a number of comfort annoyances for homeowners, including:
- working
- Restricted airflow
- Reduced efficiency
- Higher energy bills
2. Double check your thermostat.
- One of the easiest tasks that homeowners can do is keep an eye on the thermostat.
- Make sure 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 replaced your thermostat’s battery, now is the ideal time to do so.
- When first going over to your heat setting, turn your thermostat up a few extra degrees to ensure that it is working correctly and heating your home’s air.
There’s a common misconception that you can save money by shutting the vents (supply registers) in rooms that aren’t being used. 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 busted blower motors, mold or mildew in your ductwork, damage to the compressor, a ruptured 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. A qualified technician should be able to let you know if your equipment or individual parts are showing signs of wear during this review.
- Lubrication. Mechanical equipment needs lubrication to reduce friction between the functioning parts. Your furnace tune-up should include a complete lubrication.
- Pilot and gas pressure adjustment. As part of your tune-up, corrections 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 normal 1” filter replacement with your service. Many furnace filters need to be replaced at least every three months, which can improve efficiency and prevent operational complications.
- 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 suggestions for the coming year. This valuable information can help you establish the current condition of your furnace and what can be done to lower your energy bills.
4. Is the Furnace Getting 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 may not be getting power.
All furnaces have a power switch (just like 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.
High-efficiency furnaces can drain off several gallons of water on a daily basis. If the drain lines aren’t clear and open, the furnace will shut down.
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 area 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 many factors, 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 virtually eliminate these factors. During your tune-up, your maintenance 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 larger problem. A tune-up alone may instantly improve energy efficiency by up to 30%. You’ll also enjoy cleaner air and a cleaner residence 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 lower 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 professionally tuned can take less energy to guarantee indoor comfort. Because your heating system will function 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 professional maintenance you can expect your furnace and air conditioner to last between 8-18 years before you will need to consider replacement. However, poor maintenance is one of the top reasons for early replacement HVAC systems before end of average life expectancy.
