This 12000 BTU, 1150-volt air conditioning system was installed in our workshop. Yes, it took me about three days to install it. However, I was very careful, so there were no mistakes. Although it's only been a few days, the air conditioner runs very quietly and works very well. I believe it will run stably for a long time. It should be noted that since I installed this air conditioner myself, I didn't have a professional air conditioning technician check the system's startup and operation, but that's okay because I have great confidence in my installation and believe it will last a long time.

I have only used it once, but so far it is good.

This is the second time I've installed an air conditioner myself; I also have one in my living room. This time, I installed it in a small bedroom. Because all the parts are relatively light, installation was simple. I didn't have a proper torque wrench, so I had to tighten it by feel, being careful not to overtighten. The cheap vacuum pump and pressure gauge I bought here last time are still working and work well with the new R32 refrigerant. The product quality seems good, and the price is reasonable, but I still hope they can provide a basic parts warranty for customers.

I bought this system to supplement my bedroom's central air conditioning… I like sleeping in cool places, but I simply couldn't stand having the whole house freezing cold just to keep the bedroom cool at night—so I figured a split-system air conditioner would solve the problem. And it really worked! The system is incredibly easy to install; even if you only know a little about air conditioning, you can easily manage it. Aside from a vacuum pump, pressure gauge, and flaring tools (if you want to shorten the tubing), you only need a few very basic tools. After installation, I connected the tubing, plugged it in, and within minutes, it was blowing out cool 49 degrees Fahrenheit (about 9 degrees Celsius) air! The airflow is tremendous, and it's incredibly quiet. The indoor and outdoor units are practically inaudible. This 12,000 BTU unit easily cooled my master bedroom and bathroom in just a few minutes! If you're considering installing a split-system air conditioner, I highly recommend this one! Say goodbye to the agony of running central air conditioning all night in the Texas heat! And it's under $600—a steal!!!
