My water supply from our well had stopped working and I called First Class Mechanical. They were able to come out that same day. The problem was diagnosed and they did it right away. It was an old and worn out well pump. They had a replacement pump to the scene within a few minutes. They explained everything they were doing during the replacement and within about two hours they completed the task. I was very happy with their work, service, and pricing. Highly recommended.

Everytime I call First Class Mechanical for my plumbing and HVAC issues, they are always courteous and professional. They are accommodating to my unusual work schedule and come for repairs/maintenance when I need them to. The workers are always high integrity people and well skilled in their workmanship. The cost for repairs is always fair and easy to understand. I especially like to mention Ray and JP for their hard work and professionalism. The owner, Kevin, is a great guy too!
