Next check and clean the furnace’s flame sensor. The video below shows you how—note that this guy fixes it in about 5 minutes. We would probably use a little bit of emory paper, but he cleans the sensor with a 5-dollar bill. Another video further down the page under the discussion of “If your furnace keeps shutting off after about 5 minutes” shows the same project with a different brand of furnace.

When your furnace isn’t regularly serviced it can operate less efficiently. This increases your energy bills and also prevents your furnace from keeping your home as warm as you like. Keep your furnace properly maintained with regular service. The national average furnace service cost is between $60 and $80. Companies may offer tuneup specials that cover all the necessary testing, tightening, measuring and cleaning to keep your equipment running at top efficiency. If you have a newer system, furnace service costs may be covered by your warranty. Outside of warranty, a basic tuneup might start at $58 and a more advanced maintenance cleaning could be over $120. Here are some signs your furnace may need service:


Bryant manufactures and markets gas central furnaces that are available in single and multistage configurations, with some models capable of an AFUE rating of more than 90 percent. Bryant markets units that meet Energy Star requirements and makes others that it claims offer quiet operation. A new line of hybrid heat systems that uses gas and an electric heat pump was recently introduced. The average price of a Bryant central gas furnace is about $2,300 and Bryants are sold through their dealer network.
Your furnace's flame sensor is essentially a safety mechanism. As a thin metallic rod in front of the flame inside the unit, it's sole purpose is to confirm that your gas valves only open when a flame actually exists to burn that gas. When the flame sensor stop working, on the other hand, gas leaks can occur. To repair your furnace's flame sensor, expect to spend between $80 and $250. Even a full replacement of this part typically does not go above that range.
Dirty furnace filters are one of the most common causes of a furnace failure. A dirty furnace filter can limit the airflow through your furnace and cause it to overheat. If you suspect a dirty air filter, change the filter, press the reset button (if your furnace has one) and see whether your furnace begins to emit heated air. Change your furnace filters regularly — pros recommend changing them once a month — to ensure that your furnace continues to work properly. Unaddressed, dirty furnace filters can cause extensive, and expensive, damage to your home’s heating system.
If your furnace has a pilot light, look for the flame. Check your owner’s manual or the instructions posted inside the furnace cabinet for step-by-step lighting instructions. Usually this involves first turning the gas valve to Off and waiting a couple of minutes. Then you turn it to Pilot. Next, press and hold it down while you light the flame. Last, wait a minute or so, release it, and then turn it to On.
There will always be an occasion for you to rely on a heating or air conditioning system. The major appliances make comfortable life possible, providing warmth on nippy days and cool air during humid summers. Whether or not you use them daily, however, your heating and air conditioning systems need to be maintained every now and then to ensure that they function properly.
