He was fast to respond to my request for a quote and communicated well over the course of the project. I appreciated that he gave me a few options for replacement. Hiram was available within a matter of days, arrived on time, and replaced the unit over the course of one day. The house is now icy cool, even better than before. We're satisfied customers! read less - 8/05/2022

I got 6 quotes for ac installation and his was the most reasonable. He was also the fastest to respond to every concern. He did a great job and installed 4 units here. He would answer my emails at most the next day when others could take days. The only problem/benefit is that he is not a big company with several employees. The benefit is that his prices are very competitive. The problem with that is that he does not have stock of the equipment so he is subject to supply issues and delays so we had to reschedule or initial appointment due to that. That is the only reason that I lowered my review as I really wanted the system installed in mid-May when I had guests coming and wanted it to be comfortable here, and due to supply delays we had the installation at the end of June. However it was installed just in time as the next day it was 90 outside and I posted a screenshot of the temperature outside and the thermometer in my office with the AC on at it's lowest fan setting where you couldn't hear a thing. Also due to bad insulation in my attic, my office tends to be 5 degrees warmer inside then outside. Instead thanks to the AC installation from Hiram it was 67. The AC installation is a project I've been thinking of doing for years and Hiram helped it become a reality. read less - 7/01/2022

He was able to give us solid recommendations based on our use cases (huge downstairs space, smaller upstairs spaces) and was very communicative and professional throughout the entire process.

For instance, at one point during the install he realized a drain pipe needed to be run through an existing bedroom closet. There were 2 options with regards to how to install the pipe and he consulted me explaining the pros and cons of each before doing the work. I thought this was great as opposed to just doing the work one way and not telling us.

It is extremely obvious that he cares about doing good work and ensuring the end result is something both he and the homeowner can be proud of. I would highly recommend Hiram and would definitely ask for his help again in the future. read less - 4/17/2022

Dayl is super responsive, very well informed about the work, very clear and professional. Its not easy trying to fit ducting and central A/C into an old Brooklyn home, but they did an exceptional job. Never cutting corners, no half job or easy way out- everything correct and in the best way possible. I admire the skill and the communication throughout the project. They were quick to get the unit in and I highly recommend. I also have to note: some companies don't prioritize smaller jobs and seem like its a bother to do a job for a home and like they'd rather just work with developers or buildings. Gemini is NOT that kind of business, they took care of us and made our home improvement feel important. And each employee was respectful and respected by their supervisors. THANK YOU so much Dayl, Vishna and the entire staff. read less - 8/17/2021
