"My Central AC Unit stopped working on (of course) one of the hottest days of the year. I worked with Jim at Performance Engineering who initially offered suggestions for a quick fix: i.e, checking the circuit breaker and wiring. After determining that these were not the cause of the system not working, he quickly diagnosed the problem as a burned out rotary cap and hard start kit. Replacement was quick and easy and he checked the freon level, noting that it was a little low. The AC Unit now works better than ever. I will definitely look to Performance Engineering if any future heating, cooling or electrical issues arise."
