After dealing with some sketchy hvac repair folks in the area, hvac unlimited was a recent bright spot. I have an ancient HVAC system that uses equally ancient refrigerant and my A.C. wasn't working properly as a result. I called Friday night, and the service technician was there Saturdays afternoon. The gentlemen they sent, Jermaine was professional, knowledgeable, and diagnosed the issue in minutes and gave me a quote. Was it cheap, no. But again, ancient, hard to find refrigerant doesn't come cheap. Due to the prompt service of this company and the professionalism of Jermaine, this company will be my go-to for any future HVAC issues.
