Yes, the thermostat in your home causes the gas valve to come on inside the furnace, although in some of the newer, high efficiency furnaces the process is a little more complicated. Furnaces usually detect the temprature inside the plenum and turn on the blower to move warm air into the home. Once the home is up to temperature, the gas is shut off and the blower will run until the plenum is cooled. The gas should not go off and on until it reaches the desired temperature. The gas should come on and the burners should stay lit until the desired temperature is reached. If this is not the case and the burners come on and off, you have a problem. If the burners come on and stay on until the temp set on your thermostat is reached then all is well. If you notice your burners are not lit and the temp is not reached and the blower is on, then you have a problem that needs a service tech. Your filter could be clogged or your flue pipe could be blocked or there may be a problem with your high limit.

How does the heat pump change the way in which people heat their homes?
If you already have a forced air system, the heat-pump is not going to change the way you heat your home, it will seamlessly heat your home you just won't be using your main furnace until the heat-pump loses it's efficiency in the 20 degree f range. When it reaches that point you switch to the furnace.
Will replacing the heat exchanger prolong the life of your furnace?
The heat exchanger in a furnace is the primary component in a furnace. That said, their are circuit boards, motors and other components that can also fail regardless of the age of the heat exchanger. In my opinion, if you can afford to replace the furnace, you would be much better off. The cost of the heat exchanger with labor is probably not too much less than replacing the entire furnace.

How does a heat sensor in a furnace help regulate temperature and ensure efficient operation?
A heat sensor in a furnace detects the temperature inside the furnace. When the temperature reaches a certain level, the sensor signals the furnace to either turn on or off to maintain the desired temperature. This helps regulate the temperature and ensures the furnace operates efficiently by preventing overheating or underheating.

How can I melt wine bottles?
To melt wine bottles, you can use a kiln or a glass melting furnace that reaches high temperatures. Place the wine bottles in the kiln or furnace and heat them until they melt and can be shaped into desired forms. Be cautious as melting glass can be dangerous and should be done with proper safety measures.

How can I melt silver without using borax?
To melt silver without using borax, you can use a high-temperature torch or furnace. Heat the silver until it reaches its melting point of 1,763 degrees Fahrenheit, then carefully pour it into a mold or container to cool and solidify.
What is the cost of a heat exchanger for a furnace?
The cost of a heat exchanger for a furnace can vary depending on the size and type of furnace, but typically ranges from 300 to 1500.
Why does the furnace run, then shut off, and start again?
The furnace runs, shuts off, and starts again to maintain the desired temperature in the house. When the temperature drops below the set point, the furnace turns on to heat the air. Once the temperature reaches the desired level, the furnace shuts off to prevent overheating. If the temperature drops again, the furnace will start up to maintain the set temperature.
Why does Furnace shut off when very cold outside?
A heat pump will do this, a furnace should not. Are you sure you have a furnace?
What is the cost to replace a furnace heat exchanger?
The cost to replace a furnace heat exchanger typically ranges from 500 to 2,000, depending on the type of furnace and the complexity of the installation.
