Thermocouples by Treat's Heating & Cooling A thermocouple is a part made of two metal types.  When one end of the thermocouple is heated, it will create an electrical charge at the end of the pilot light.  When the part releases its charge, it triggers the gas valve to open and then releases the gas flow to the burner.  If you are having problems with your pilot light staying lit, it could …Read More

Thermocouples by Treat's Heating & Cooling  A gas furnace thermocouple is in place to shut off the gas line when the pilot goes out of the flow of gas is interrupted on its way to the pilot.  It works as a sensor and if it fails, your furnace will not light.  A thermocouple is the right hand man for the pilot as it reads the pilots temperature and rating and tells it to keep the gas flowing…Read More

Furnace Sounds by Treat's Heating & Cooling You may not think of your furnace on a daily basis but as soon as it starts to make strange sounds, you want to know what is wrong with it.  Not all the sounds a furnace makes mean you need to be worried, but we are going to educate you on a few of the common sounds you may hear and what might they mean. Screeching: this may be a bearing in the moto…Read More

Furnace Sounds by Treat's Heating & Cooling If your furnace is making a loud noise when it turns off such as a loud banging or thumping, there are several reasons that this could be happening.  The sound can be caused by the sheet metal in your ductwork being bowed outward while the system is operating and then it contracts once the air is no longer being forced through. This can happen as a …Read More

Furnace Sounds by Treat's Heating & Cooling Here are some common reasons that your furnace might be making loud noises.  The first being delayed gas ignition and expansion and/or contraction in metal ductwork. If a banging noise is coming from the furnace, it may be delayed gas ignition.  When a furnace builds up rather than igniting, after some time when the furnace does finally ignite, a m…Read More

Furnace Sounds by Treat's Heating & Cooling Are you hearing a loud thud or bang coming from your furnace when it first turns on?  Hera is a few possibilities of what could be causing these sounds.  Your furnace burners might be dirty; having dirt on the burners may cause a delay in the burners igniting.  Because of this delay, gas will build up which causes the loud bang when it does finall…Read More

Furnace Sounds by Treat's Heating & Cooling It is disturbing when you turn your furnace on and hear a loud boom.  There are a few common reasons that this is happening.  Delayed ignition and expanding air ducts.  If your furnace makes a clicking noise trying to turn on and then makes a loud bang noise right at the furnace location, it is most likely delayed ignition.  If the noise originat…Read More

Electronic Ignition by Treat's Heating & Cooling A standard pilot light was the most common way to ignite a gas-powered furnace for almost as long as this equipment has existed.  Now electronic ignition systems have started to replace pilot lights.  Because an electric ignition does not need constant power the way a pilot light does, it will contribute to energy savings.  The electric ignit…Read More

Electronic Ignition by Treat's Heating & Cooling Furnaces have a process by which they ignite; this ensures safety and correct combustion.  Older furnaces usually have a pilot light and higher efficiency furnaces come equipped with an electric igniter.  There are two different types of electronic igniters and each works a little bit different.  If you have a furnace that won’t stay lit af…Read More

The electronic ignition in a gas furnace is a development that allows reliable performance, energy saving and contributes to better efficiency.  For example furnaces that have pilot lights have a small gas flame that burns constantly and wastes energy by constantly burning gas. An electronic ignition typically occurs in one of two ways, intermittent pilot or hot surface ignition.  The intermitte…Read More
