Instead of stripping wires where there are no terminals to hook a multi-meter to, They make inductive probes that you just touch to a insulated...
The drain pan and coil is either located before or after the blower in a air handler & duct system. The return air side (before the blower) is a...
Don't forget there must be a trap on the evaporator drain line. (because of the differential pressure in the air handler) If not, the pan will...
The First thing you do on any suppression system is insert the safety pin in the firing mechanism then after the bottle is disconnected put on the...
One thing most people don't realize is if the evaporator temperature is low (say 6 f. or 30 f.), the unit will remove much much less heat...
You can't use a rheostat to slow a AC motor. That will lower the voltage and burn it up. Many motors have 3 or 4 speeds using multi wire taps. A...
CSkipR did you use a infrared thermometer for the temps you posted ?
You need ~ 400 cfm per ton.(12,000 btu). Too much airflow and you lose dehumidification. To low and the coil freezes solid.
There should be ~ 20 F degrees temp drop across the evaporator. The master is way off, at 6 degrees the evaporator coil will freeze solid. If a...
Your correct about the superheat, it should be higher. High head pressure does matter, but a overcharged unit with high head pressure will show...
But if the charge is low ,there's a leak....unless freon was lost from putting gauges on and off.......Knight you said in post 7 that a low charge...
The compressor with the lower temperature is the one with the problem........If you have a volt/amp meter measure the voltage of both compressors,...
The high side is not as relevant as the low side pressure. you are correct, More than 50% of ac units are overcharged. I usually need to remove...
