Called 72 Degrees because their sister company, Plumbing Masters, had done some work for us. Our A/C had been malfunctioning and leaking water. The technician from 72 degrees said that it would cost $3,000 just to repair our existing A/C unit, so we may as well get a new one for around $6,000 (which was the negotiated price from the original quote of $9,000). Obviously we wanted a second opinion, and I'm glad I called someone else. Another company came out, found the problem, and fixed it for under $200. No need for a new system at all!
The 72 Degrees technician didn't even open up our unit completely to find the problem. He took advantage of our A/C ignorance and insisted that we needed a new unit. Unacceptable.
