Hello, Suppose we have two split Air conditioners or freeze/refrigerator compressors. First works with AC and second works with DC. Which one has a longer life? What are the pros and cons of compressor work with AC vs DC? Thank you

I live in the Middle East and we don't have a national electrical wiring code or anything like that. More than 75% of electrical contractors don't have any certificates or enough knowledge.

Sure, I don't want to do electrical work. If the cable is thick enough and the fuse capacity is sufficient, is there any other problem? When the second AC is turned on, does the voltage sag/drop and fluctuation occur in the first AC? Can it be harmful to the electrical board and compressor...

Hello, We have a mini split AC Inverter. We need electrical wire for the second mini split AC inverter. Can we get a wire branch from the first AC terminal? Do the voltage drop/sag and fluctuation occur?

The problem was from the drain pipe! It was due to the accumulation of water/water building up. (Although we had the drain water outlet properly and did not have any water leakage.) We installed a pipe with a smaller diameter and the problem was solved. Now we have the following pattern, but the...

Hello, Suppose we have a building that is 30 years old. It is being overhauled. Do the copper wires need to be replaced? Do electrical wires have a useful life? In our country, electricians don't have certificates and they learn through experience. They don't have technical and theory...

Thank you, but I don't understand. The first one Rated Current is 9.56 and the second one is in 16 A.

Hello, I am seeing two mini split ACs with the same cooling capacity in two different companies. Both 24000 BTU and Inverter. The first one said Rated Current is 9.56 A and didn't write Max current or current. The second one said the Current is 9.9 A and the Rated Current is 16 A. Does...

Please see the video, He used the below method instead of a vacuum pump.

Thank you, I will not do it. The technician will do it. Could you please more explain about it? Is it true that some oil is discharged when the refrigerant is completely evacuated? Does the oil decrease? (I mean when we want to release all the contaminated refrigerant and put in new...

Hello, The technician installed a new AC split without a vacuum pump. (Gree 24000 BTU Inverter) Should we drain the refrigerant, do vacuum, and refill the refrigerant? It is written in the AC manual that we should vacuum during installation. I read that air and humidity are harmful for the...

No, It is not installed.

Thank you, I don't know, but I attached AC technical specifications. (PDF file) One indoor unit. Your link is not the manual of the AC, but I do not have any errors on the LED display.

1) I don't know. (Some people say that inverter ACs are like this.) 2) 3-4 times. 3) at 100% airflow and cooling.

Do you think I should do a vacuum now? Of course, we have to empty all the gas and refill it.
