Very prompt service. He came right over and was done in a short time.
Eftain communicated well, letting me know when he's on his was and when he arrived. I had another ac tech say I needed a new compressor. Eftain checked the system out and suggested doing a hard shock to the system which turned on my compressor. I'm thankful for his honesty and professionalism.
