"From the first call to rep (Millisa) to the tech who did the repair was customer friendly and effiecent I hired them for a repair in my father's house they had a tech there within 2 hours repaired the problem and pricing was great.

Tech showed up ON time pricing was in line with job done I recommened this company to my neighbor and would recommend them in the future. GREAT customer service"

"I can't say enough about the team at Old Skool HVAC. I learned of this organization from a close friend who had work done and recommended them. Frank is a great guy. On time, professional, knowledgeable, and his team is a reflection of this as well. They were always on time, on schedule, clean, and very personable. They finished our job a little early, and during the first heat wave just about week or two ago, our house never felt better. Great service, quality, and pricing. It's funny, with central AC, you never really know that it's hot out until you leave the house and come home. It's during this first transition that I realized how quiet and effective of a system that was installed. If you are looking for any form of HVAC work in your home of business, I'd recommend contacting this group of professionals."

"I was shown pictures of problems that I did not know was going on. I have had a heat pump in my Attic and I showed that mold was in and around my unit. I am thankful to James for showing me this and I was told about equipment that can be installed to make sure that we do not breathe this air that can come into our house. I got the repairs done today. I asked James to send me information about the type of unit that they can install to help with this problem."
