When I bought my considerably extravagant air conditioner, I fully expected it to work, not just passably, however better than any run-of-the-mill system that I could have bought for less! What I came to understand is that no matter how fancy or extravagant, air conditioners need proper repair & upkeep to continue to be able to perform their works well. I knew my part, at least. I would correctly change the air filters & make sure that the outside units were clear of debris; Occasionally but, issues require a professional. That is why I have common repair done on my unit. That said, it had been a good long while since I had an Heating & A/C check up, when I started to notice that the cool air coming from my air conditioner vents was start to wane; Even when the control unit was set considerably low, it seemed that the undefined could not reach those low temperatures anymore. I knew it wasn’t the air filter & I knew it was not a faulty control unit. The problem was start to tick myself and others off until I learn about something else that I could do to assess the problem. I went to go examine the condenser. Specifically, the numerous copper lines that go into it. I had learn that the larger of the numerous lines was supposed to be cold to the touch & covered in sweat if there was enough refrigerant. I saw & felt that the copper line was not nearly as cold as it should be & there was barely any condensation. It was clearly time to call out an Heating & A/C professional to replenish the refrigerant in the system or repair the components involved with the refrigerant.
