Work Description: Ductless (mini-split) A/C Install

Comments: This was absolutely the worst experience I had, would not recommend. Otto suggested that I add a variable speed blower to my HVAC, and pressured me to do it fast because prices was going to increase by 25% the following week. When he men came to do the install, overheard them saying they thought it was odd to be replacing a heating element in the AC months. It did not fix my issue, and Otto had given me a guarantee to add a return to the top floor if it would not work. It was a painful process to get the return added. Every time I called to schedule the return, Otto said he was busy and would call back, but never heard from him. Then he said fell sick/hospitalized and didn't hear from him or the company for 2 weeks. Finally one Wed, after I reached out Otto said he would have someone come out Friday, and I had to follow up multiple times for the timing. When his guys came, they were very annoyed they were given the job.. and that they were only told an hour before and didn't have what they needed to do the work. Had to reschedule. Also I kindly asked about Otto recovery and wished him well, and even though it is a small family own business, the guys had no idea there was anything wrong with Otto's health.

Work Description: ac installation

Comments: Had a new ac installed and can't register it. There was no ac paperwork for the air conditioner so i can't register it. I need to register it so i can get my warranty. Many calls have been made to Otto and he said he would stop many tiimes. Now he just doesn't answer the phone. Please help us.

Comments: Tim and Sabastian were very professional, prompt and successfully installed our new a/c unit. They also did a good job cleaning up after themselves.
