How a Central Air Conditioning System Works
amn_howac.jpg


Facts:
  • The typical central air conditioning system is a split system, with an outdoor air conditioning, or "compressor bearing unit" and an indoor coil, which is usually installed on top of the furnace in the home.
  • Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors and remove it from the home.
  • Heat and moisture are removed from the home when warm air from inside the home is blown over the cooled indoor coil. The heat in the air transfers to the coil, thereby "cooling" the air.
  • The heat that has transferred to the coil is then "pumped" to the exterior of the home, while the cooled air is pumped back inside, helping to maintain a comfortable indoor temperature.
  • Central air conditioning can also be provided through a package unit or a heat pump.

Benefits:
  • Indoor comfort during warm weather - Central air conditioning helps keep your home cool and reduces humidity levels.
  • Cleaner air - As your central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply ductwork that carries it back to rooms.
  • Quieter operation - Because the compressor bearing unit is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning unit.

I recently replaced my furance in my moblie home an now o have a Intertherm gas furance and i would like to have owners manual with it it did not come with one thank yoiu


Hi, most of the time, they tuck the manual in the heating section of the unit. Look around and you may find it. If you have then go with what Mike said to do.

I recently came to home to find my furance (natural gas) running but it was blowing cold air. I pulled the filter, it was dirty, cleaned it and replaced it. I turned the furance back on and it worked...


You are resetting it every time you take the panel off the front of the unit. It is locking out the circuit board. No. 1 reason for this is a dirty sensor. The flame sensor is the small rod-like part that senses the flame of the burner. It is usually pretty close to the hot surface ignitor (the part that glows bright when the furnace is igniting) Watch your furnace burner light. You will see the ignitor come on. The sensor is a little bigger than a pencil lead and it will be just a couple inches away from the ignitor.

Take the sensor loose and clean it only with fine sand paper or emery cloth. Chances are this will solve your problem. Hope this helps

AC IS TURNING ON BY IT SELF AFTER I SWITICH IT OFF, HOW TO SOLVE THIS PROBLEM


Sounds like a problem with the furances circuit board. With the furance powered off, disconnect the two wires at the circuit boards thermostat terminal strip. These are probably red and white wires connected to the "Y" and "C" thermostat terminal strip on the circuit board. These two wires send 24 volts to the outside A.C. condenser unit when the thermstat is se tinto the cooling mode. With the thermostst in the "off: postion measure across the "Y" & "C" terminals at the furances thermostat terminal strip. If you have voltaged than either the board or thermostst has failed. The next step to determine which has failed is this. Disconnect all the thermostat wires at the furance. To check the heating circuit jumper across the "R" & "W" terminals, the furance should fire off for the heating circuit and run non stop beacause the thermostat is no longer controlling it and is isolated from the furance. Now remove the jumper and jumper across the "R" &"Y" terminals, the blower should run at your furance for the cooling mode and you should have 24 volts across the "Y" & "C" terminals for the outside A.C. condenser compresor contactor.Next check for blower operation by jumpering across the "R" & "G" terminals. If everything checks outs than the thermostst is the problem. Tou may also want to check the control wiring at the thermostts , furance & out side condenser unit. If the wiring has connnected somewhwre between these points or at the terminal connection this may also be bring on the A.C. when the thermostat is in the "off position.

Unless we set the thermostat very high, like 80 degrees, the heater will blow cold air. When the heat does blow, it will eventually stop blowing heat and the fan will continue to blow cold air.


Check and make sure the filter is clean. This sounds like a restriction in the system. If the unit has central cooling make sure ther indoor evaporator coil is clean at the furance.The unit may be cycling the burners on and off at the high heat limit , fan/limit control. You can also eliminate the thermostst from the furance. Turn power off at the furnace and disconnect the wiring from the thermostat. Jumper the red and white wire together. Turn the furnace back on. The furance should run in the heating mode. Try this and see if the problem is still there.

Blower fan wont shut off


Try cycling the switch at the furnace to reset the blower board. If this doesn't work remove the green wire from the blower board(computer board) to eliminate a shorted t-stat or shorted wire between the furance and t-stat. If blower remains on, then blower board is shorted. I've seen all these problems.
