“Josh is an outstanding professional providing the BEST service! Easy to understand and very efficient!“

“My elderly parent's well pump failed and they were out of water. They placed a call to First Class Mechanical and they showed up the same day. Not only did they have the needed parts on their truck, but they were experts, very professional, and made sure that my parents had their water back up before an impending Winter storm. I am very thankful to Gary and his team for the quick, professional, and excellent work! On top of it all, they were exceedingly reasonable in terms of pricing. We will keep First Class Mechanical on speed dial for any future repairs.“

The crew was polite, professional and worked quickly. Very fair price. They even took the time to explain to me the work they did and how to keep up with the maintenance on the AC unit. Will definitely be using them again“

“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.“
