“My family and I are very happy with the work that Roger, Jesse and Armando did on replacing and relocating our AC unit. We got different bids from other companies and his bid was very reasonable in price. We also liked the way Roger presented his bid, very professional as he is a Mechanical Engineer. He included pictures and notes so we could understand exactly what was going to be done. During the process, Roger promptly pulled the city permits, always made sure the job was being done correctly, communicated with us on the process, and checking with us for any questions. Roger communicated with the inspectors and handled the inspection professionally. Jesse and Armando were also very knowledgably and respectful. They always cleaned everything each day. Overall, we had a great experience with this company.“
