How much does a new Carrier furnace cost?
Gas or electric? How large a furnace? How efficient does it have to be? Do you want an energy rebate for your willingness to pony up for a unit that operates well past 90% efficiency? With the lack of more specifications in the questions, the answer cannot be anything other than a wild guess or a range. Entry level units might be had for $500 to $600 (not including installation), and can run into $1000's for the top of the line.

Furnace thermostat goes on and off frequently?
I WILL ASSUME THIS IS NOT A POORLY INSULATED LEAKY HOME, IN THAT FREQUENT CYCLING OF EQUIPMENT IN THE AFOREMENTIONED BUILDING WOULD BE NORMAL. 1) CHECK THAT THE CAVITY BEHIND THE THERMOSTAT IS SEALED, WHERE THE WIRING COMES THROUGH THE WALL. (DRAFTS OF THIS KIND CAN CAUSE THIS SYMPTOM) 2) CHECK THE HEAT ANTICIPATOR ADJUSTMENT ON THE THERMOSTAT ITSELF. IT SHOULD CLOSELY MATCH THE CURREND DRAW (IN AMPS) OF THE FURNACE LOADS DURING THE HEATING CYCLE WITH THE BURNER OPERATING. IF YOU HAVE AN AC AMMETER, YOU SIMPLY PUT IT IN SERIES WITH THE "W" WIRE, AT THE FURNACE MAY BE EASIER THAN AT THE T-STAT ITSELF. THE ANTICIPATOR SHOULD BE ADJUSTED TO THE MEASURED METER READING. (BETWEEN 0.2 AND 1.2 AMPS NORMALLY). IF NO METER IS AVAILABLE, SIMPLY INCREASE THE ADJUSTMENT SAY 0.2 AMPS FROM WHERE IT IS SET NOW AND CHECK OPERATION. MANY ARE LABELED "LONGER" WITH AN ARROW POINTING IN THE DIRECTION OF INCREASED AMPERAGE. MANY ELECTRONIC STATS HAVE DIP SWITCHES ALLOWING YOU TO CHANGE THE CPH. (CYCLES PER HOUR) lc

Sharp, noisy blue flame=too much air
Blue flame with defined inner lighter blue cone= just right
Soft blue flame with yellow tips=not enough air, or using LP gas
Most times can be adjusted with the primary air shutter on the burner tube, being careful to check for good ignition after adjustment.
Caution: a yellow flame can carbon/clog up the heat exchanger eventually.
A structure or apparatus in which heat is generated, as for heating houses.

Did King Nebuchadnezzar throw the three Hebrew children in the furnace?
The Bible, Book of Daniel, Chapter3
King Nebuchadnezzar was the king of Babylon. The Hebrews or Israelites were in captivity there. When the three men, Shadrach, Meshach, and Abednego refused to bow before the statue that King Nebuchadnezzar made, the king became very angry and ordered that the furnace be heated seven times hotter than normal. The king himself did not throw the Hebrew men into the furnace. Those who obeyed the King's commandment, and did cast them into the fire, were killed by the fire. The three Hebrew men who were thrown in were seen walking in the fire with what appeared to be a fourth man. King Nebuchadnezzar called them out. They came out unharmed and not even the smell of smoke was upon them. These three Hebrew men were referred to as children in Daniel, chapter 1, verses 3 and 4, but had grown up and had been given adult responsibilities by the time the event happened in the furnace.
How do you detect a crack heat exchanger in a furnace?
The most comon way to detect a crack in a heat exchanger is with a visual inspection, removal of the burner assembly and the use of a mirror and flash light. Or a smoke bomb test. A special little smoke bomb is placed in the burner area with the burners OFF. The blower is runnig and you light the smoke bomb, the smoke will draft up the flue vent or if a crack or rust hole is present then the smoke will get sucked into the air stream and come out of the duct work. Other than that using a carbon monoxide detector to see what the CO levels of the furnace are and comparing them to the supply air of the furnace to verify that there is no CO present in the air stream. The best and most accurate way is to contact a local Heating and Air Conditioning specialist or your local gas company should come out and perform a CO test on the furnace. Good Luck and God BLess
