“Our well pump went up on Friday night of Labor Day weekend leaving us with no water. I called First Class Mechanical that night and they had 2 techs at our home bright and early Saturday morning. They quickly diagnosed the problem and replaced our pump for a fair price. Water was flowing by 9:30 the next morning. The techs were very courteous and we are very happy with the service we received.“

“Very professional and job well done. Recently moved in and our master is an addition over the garage. All summer it was hot so David came to assess the situation and suggested a solution - a mini split. It looks great, is so quiet, perfectly installed, and now I’ve even tried the heat function since it is getting chilly out and it is fantastic. Communication was always super quick and we were well taken care of. He even set up the warranty for us - which I probably would have neglected to do. Highly recommend!Service: Installation“

I even signed up for their maintenance plan to have my units serviced twice a year. I would highly recommend them to everyone.“
