Absolutely a great video. Trouble shooting if condenser fins become restricted with dirt/ grass or fan stops what temp rises to at metering device. Also on low side, if return air filter is clogged and not enough air flow through the evaporator. I have seen air registers closed in 4 rooms with a 5 ton unit and customer doesn't understand why the A coil is freezing up. They will tell you, I am not using the rooms, so I shut off the air flow to save on electricity. The opposite happens, coil freezes up, the rooms needing cooling are not receiving air and the compressor never shuts off. Allergy filters will cause more trouble than they are worth just from restricting air flow. This is one of the best videos I have seen on you tube with a piston/orifice devise.
@coolcathvacrtrainingvideo99065 жыл бұрын
Thanks for the compliments. I have a tip for checking for clogged condensers. Some condenser coils have an overlap design. Dirt and trash will collect in the center (due to the overlap and the fins don't match up) and won't be seen on the outside. You'll need a flash light shining back through the coil to detect the obstruction. Also on the allergy filters. They are rated by something called a MERV rating. What they don't tell you is that they become so restrictive they kill the air flow and the evaporator freezes up. they aren't cheap and require monthly maintenance but an electronic air filter is the best way to go.
@garybarbourii82748 жыл бұрын
EXCELLENT!!! This video alone has saved me HOURS of watching other mediocre videos! Thank You! The only thing I need to find now is how you got 35 degree application to 10 SEER and how the Rh affects the numbers
@coolcathvacrtrainingvideo99068 жыл бұрын
+Gary Barbour II Subtracting 35° from the indoor air temperature is used for standard efficiency equipment (10 SEER). Subtract 30° for high efficiency (12 SEER and up). The moisture in the air, humidity, acts as a load on the evaporator due to the change of state. The evaporator operates below the dew point so any vapor moisture that comes in contact with the evaporator condenses to liquid and leaves in the condensate line. Absorbing the latent heat to condense the moisture is additional load on the system.
