Got my compressor checked by Dave L. Knowledgeable and friendly guy. I also had a good experience with the customer service rep who took my initial call. Overall, I think this is a solid business. They’ve been around for over 40 years, and have a good word-of-mouth reputation. Kudos to Burkholder. Update: 05/25/2018 Burkholder’s came for routine maintenance. Their guy Keith ran through the system with thoroughness and speed. Very well presented gentleman, and knowledgeable. Keep up the good work guys!
