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.

I woke up at 6:30 with my smoke detector going off. Changes batteries but that didn't work. Web said they might be end of life, so I turned to m electrician. Parrish was wonderful! She was patient with me and went out of her way to help get it add today. Alton was the tech who was also helpful, patient, and informative. He came out and fixed the problem. He was professional and made me feel listened to. Cost was reasonable. Highly recommend this company.

Andre and the other technician did a great job installing the new furnace hot water heater and air conditioner. I appreciated the prep and care taken in my home as they carried out the old and brought in the new furnace and hot water heater. Andre took the time to answer what overall questions I had and kept me up to date on the installation progress.

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.

Alton conducted a comprehensive inspection of our home's electrical system. He explained issues as he found them, and even made water heater and fire safety recommendations. I was pleased with his ability to communicate issues clearly and provide a quick turnaround for the quotes.

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!
