Can anyone recommend a good A/C guy in the West Valley area? Every year when the weather heats up, the A/C at one of my rentals doesn't work due to lack of coolant. I have had a tech guy come out each year, they add freon and it works ok for a while. Then I have the same problem the following year. There must be a leak. I'd like to get somebody out there who can fix this so I don't have this problem every year. My A/C unit was replaced about 8-9 years ago, so it should be serviceable. Thanks.
