Based on our first encounters with Parrish Services and the technician, Nizil, we expect to have a good relationship over the long term under our new maintenance service. The scheduling is efficient. Nizil is pleasant and knowledgeable. He identified important additional services that I did not consider to be unnecessary upselling, as was the case with our previous service.

This was my 1st experience w Parrish, and...THEY WERE GREAT! From my intial call, to working w Eric about the job and the estimate, to working w several office folks and dispatch prior to the job, and then to day of, EVERY interaction was really great. Many extra thanks to Eric, and it was HE that really made me want to work w him and Parrish. In 110 degrees in my attic, he addressed my HVAC repair and got me back up and running. 5 STARS here!

Great experience. Scheduling was easy. Technician showed up on time and was prepared for the job. Alton Wallace did a great job and was very professional and patient (my dog was being a little bit annoying...treats helped).I would definitely use their services again.

Great experience. The Technician, Mariusz Loniewski, was very thorough and did a detailed diagnosis and gave me a bid to repair. The main office quickly follows up to schedule the repair work.

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.

You arrived promptly at the scheduled time, demonstrating a strong commitment to punctuality. You conducted a thorough and meticulous inspection of the gas systems, ensuring every detail was carefully examined. Your knowledge and attention to safety measures were remarkable. Thank you

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.
