Dwayne responded to my call promptly and a few days later arrived on-time. He quickly diagnosed a leaking service valve but proceeded to perform a thorough analysis of my entire HVAC system. He efficiently confirmed there were no other issues. He ordered a new valve and a few days later returned on-time, carefully installed the new valve, and recharged the AC lines. Using the latest instrumentation technology and techniques to ensure optimum mfrs recommended set-up. My 11 year old Carrier AC now looks and runs like new again. I highly recommend Dwayne.
