I had a great experience with Parrish, and the head technician, Danny Shoop (the assistant was also very good). We had a number of plumbing issues that needed repair, and the work was completed to our satisfaction. I was impressed by Danny's professionalism, his work ethic, and the suggestions and recommendations he made. I will definitely use Parrish again.

Brandon did a routine inspection of our HVAC that we knew was reaching its replacement age. He was very professional and honest with his assessment and what needed to be repaired or replaced and why, complete with photos and diagnostics. He made sure I knew all my options and pricing (including cost savings) for the recommended parts and services. Very happy with Brandon’s service and Parrish in general.

My wife, Janice, worked with Alton Wallace to convert our fireplace from gas to electric, and Alton was wonderful! We’d never tackled a project like this before so we had some questions along the way, but Alton was very patient and willing to walk us through step-by-step. He was personable and very knowledgeable. We would definitely recommend Alton to future clients!
