So many guys would have just shut it off and come back later. Very few techs actually check out the mechanical stuff on a frozen coil. So lazy.

Good find. Life would be so much easier if install crews knew how to operate a Sharpie marker and put a few notes on the air handler/furnace. I know, most of them will never see the equipment again and what they install will never drive them nuts.

How did u clean the compressor

I had frozen coils on mine once and it was because condensate drain was blocked and water leaked onto the AH filter. Usually frozen lines = a refrigeratant leak, low on charge, or bad filter. In my case it was a wet filter.

@thehvachacker

3 жыл бұрын

Wet Filter blocks airflow the same as a dirty plugged up filter. Frozen lines are from the symptoms you listed. With one added scenario: system left on long time after the evaporator froze. Many don’t shut down the system when it’s not working.

My Mac once in a while froze like that one you work on I turn off the compressor because it kept running and power off and on the thermostats and it work again Is that what I suppose to do sir because expert ac guy don’t know

I see where they are phasing out HFC refrigerants. Glad I stocked up on 134a on Amazon for the old Expedition. You know the price will begin to go up now. I recently bought a Chinese made window unit for AC backup to be run by a generator in case of power loss during a hurricane. It warns not to puncture it due to possible fire hazard.

I just fixed up the ac line frozen because the renter set up the wrong temperature two hours ago. I took less than one hour to turn ac on.

Just one damper not opening can cause it to freeze up? I believe you. But could you explain how? Is it because the thermostat for the area couldn’t ever satisfy?

@thehvachacker

3 жыл бұрын

If you have no air flow what happens to the evap coil? It freezes. Therefore if all zones are closed and the ac is running you have no airflow. That causes the coil temp to drop below freezing and start icing. Yet that was a symptom. Not the main reason for system freezing. The main reason was revealed later in the video

@jamescordes8673

3 жыл бұрын

Not enough air flow over the inside coil will cause it to freeze so if that zone is calling and no others are then the air is going nowhere and will freeze the coil. Lucky for her other zones seem to be calling more but the system would never shut off too.

Great video. My suction line is frosting up. Indoor temperature is 75F and outdoor ambient is 70F. It's r410a with low suction pressure. The low side saturation temp is 28F. I am getting low superheat but normal subcooling with fixed orifice. Filter is clean and air flow is good. The coil has no frost but frosting just before service valve at outdoor condenser. All amp draws are good. I tried adding some refrigerant but the low side pressure would not rise. I just can't figure this one out. Any help would be greatly appreciated. Thank you.

Is the system overcharged? Low superheat seems like an airflow problem or overcharged. Is evap coil possibly dirty? Subcooling not that important with fixed orfice. Superheat is used for charging piston systems.

@dantemariscal8679

No, the zone control was stuck closed because of the fallen wire and it causes an airflow restriction which causes units to ice up. The burned contactor isn’t necessarily a problem because it’s still kicking in and out when he takes off the thermostat wires but it is an indicator that something is over amping and 90% of the time it’s the fan motor

5:54 Nice diagnosis. If you want to be a great technician or scientist- slow down- think- work the cause and the effect. One of your better vids. Get the wago lever connectors brand (germany ) by them from an electrical supplier store unless you can verify the amazon seller (there's china knock-off wago's). That HZ2432 board was installed in an inappropriate service area, IMO. On another note a doctors office should have better clean air manage ment standards- can only imagine the bacteria, virus, mold etc in the air handler/duct system.

I the new aluminum coils seem to hold up a lot better. I think electrolysis could be a factor. Most Lennox leaks are back corner opposite of drain side near bottom. Right where the copper goes through the steel. We will see. I don’t think the class action lawsuit was 2014, units covered many years after that. I think 2014 was the Copeland compressor sludge that took out many txv’s on Lennox units. Yet time goes so fast it could of been both.

All he did by pulling the disconnect was turn the compressor off. Control side was still calling for cooling, which he demonstrated by testing the contactor. There was no benefit to leaving that unit running, as it being that frozen up would cause low pressures and hide the refrigerant leak. Best to turn off the compressor and let it melt as soon as you can. Obviously doesn't apply to all situations.
