Do you perhaps mean the 'lineset'? If so, it is usually a copper line (actually 2 copper lines) running counter-currently. They connect the indoor evaporator coil (above furnace or air-handler) to the outdoor condenser. One tubing carries the refrigerant gas from the indoor evaporator coil to the outdoor condenser and the other line carries the condensed (liquid) form of this gas back to the evaporator coil for it to be evaporated again and be converted back to gas. This is the refrigeration cycle of an A/C unit.
If the unit is a permitted piece of equipment, like a central Air conditioning unit, it gets hardwired. If the unit is removable , such as a window unit, it will have a cord on it.
A central air conditioning unit will commonly turn on and off intermittently. To stop this, adjust the temperature on the thermostat or switch the unit either on or off rather than the automatic setting on the thermostat.
You should not have to calculate the watts of the unit. All the information that you need will be on the nameplate of the unit. It is this information that electricians use to calculate the conductor size and breaker to supply the power to the unit.
smelled electrical burn now central air is blowing warm air non stop
It could be off on a low pressure switch. You need to check if you have 24 volts to the outdoor unit at the contactor coil. If the contactor is not working the outdoor unit will get no high voltage to the compressor or fan. It could also be that the capacitor for the fan and compressor is blown.
frozen line on what? An air conditioner? Central air or window unit?
unit is most likely low on refrigerant due to a leak, or compressor in the outdoor unit is not running.
the big line is the suction for the the compressor in the A/C unit, The small line is the compressor discharge that goes to the furnace
It means that the unit is low in freon and the line temperature is to low.
The suction line will be the larger line going into the compressor.
Inside the unit under the evaporator coil. The condensate drain line is attached to it.
how to check out the relay in a central air conditioning unit
your central air need re-gassing It means that you are probably low on refrigerant.
in air handling unit
Omg not a leaking central air unit those are the worst
Iowa Central Air Line Railroad ended in 1864.
Iowa Central Air Line Railroad was created in 1853.
