For a long time my apartment cooling system hardly worked. I tried getting my property owner to call a cooling contractor and the guy just wouldn’t. He said that he had a cooling contractor over to check my device before I moved in and would not do it again. I thought my property owner was lying to myself and others about it. Turns out he was not and the fix was a simple a single. I was outside a single morning and noticed the outdoor unit with my AC machine was at an angle. Not a immense angle, however enough that I noticed it. I then did some research online and found that a slightly tilted AC unit can make the refrigerant run to a single side. When all the refrigerant goes to a single side, the AC does not work as good. People have said you can tell when the indoor AC levels are just not cold enough. I then took a few pieces of wood and shoved them under my outdoor unit. I got the machine to get back to a level ground and there has been quite a change in my home. My cooling plan runs appreciate a champ now. I honestly had to raise the temperature on the thermostat since the AC was so effective. It worked hastily, efficiently and I have all the AC I want. My yearly bills have decreased by a noticeable amount. It is amazing how such a small fix has made such a immense difference. I am delighted that the AC contractor did not come into my home too. That would have been an embarrassing appointment.
