I used JA Sauer a while back for an emergency service call on my A/C after another company had disappointed me. The JA Sauer technician was so professional and identified a critical issue with the original installation that no service person had noticed in the 6 years I'd been having problems! So, later, when I needed a new A/C, I called JA Sauer again to install an updated A/C unit and a return air duct and register.
They sent Mark out to give me a quote and he spent half the afternoon trying to find a way to accommodate my needs exactly. He offered 3 options that were all within my budget, took care of a permitting and variance situation, and got me scheduled for install right away.
Let me just say that these guys worked their asses off for me. I'm on the 3rd floor of a condo building and they had to run up and down the steps maybe 100 times while installing the air vent. They went above and beyond to make sure I was happy and dealt kindly with the scheduling issues we encountered due to needing access to a separate condo unit for the install (thanks to Danielle who was essential in helping us rearrange the schedule last minute).
I can't say enough good things about Anthony, Joe, and the rest of the team who did so, so much work. I'm sure they could have done a "good enough" job and called it a day, but they stuck it out after hours to get it just right and did an exceptional job. Big thanks to everyone involved from a happy customer!
