Emalie Johnson Steele

I was really impressed with the radio ad. I will be calling you soon to check out the air conditioner before it gets hot. You can't beat the price for an air conditioner check up. Great Co. Great name, because you are FIRST CLASS.

Jane Mahoney

We recently had our crawl space encapsulated and our air conditioning units replaced courtesy of First Class. We could not have been more satisfied with the service and professionalism of the sales men and both crews who worked at our house. Duane, who sold the AC units, was prompt and thorough in evaluating our situation and recommending what would best meet our AC needs. He also recommended we have our crawl space inspected by Al who is an expert in home performance. This was something we had talked about doing so we jumped at this opportunity. Al stopped by on the next day, inspected our crawl space, and impressed us with how knowledgeable he was about the health of a home. We decided that the recommendation he made was right for us. Both Duane and Al collaborated to schedule the work to be done quickly and in the most efficient way

The AC installation crew included Ben, Chris and Chad as well as Jacob and Alex. They were professional and efficient and very considerate while working in our home. They answered all questions and were very patient in explaining how to manage and control the new "smart" thermostats installed.

The crawl space encapsulation crew included Nate, Gavin and Juan. Likewise, they were most polite, professional and efficient in completing the work. They went out of their way to make sure our house looked undisturbed after each day's work. In fact, the access to the crawl space now looks even better.

Thank you, First Class, for a job well done. Each of your employees mentioned above truly demonstrated your company's name.

To First Class, thank you so much for a job well done. I love my new furnace and A C unit. Josh and Tom Hurst were great and they explained everything and I understood it too! Thanks for everything!
