"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

"A year ago they responded to an SOS related to a full A/C failure. They were prompt and professional. It took several days, in the heat of the summer, till they were able to fix it, but they had to get a part from the west coast so we sweated through the ordeal. While they were working on replacing the main board, I also engaged them to clean the system. I thought the charge was high ($1000), but needed it done. A year later, one of the A/C mini-split heads stopped working. They came the next day. I paid $200 for them to trouble shoot it, which took approximately 20 minutes. (Subsequently another A/C service charged me only $95 to trouble shoot!) They said they would order the part and get back to me. After I week, I had not heard from them. When I called they said they could get the part but it would take 4-6 weeks. I said okay. What could I say. I left it in their trustworthy hands. After 6 weeks I heard nothing from them. I called. I left 4 messages, which were all unreturned. On the 5th try, someone answered. He said he couldn't get the part. Would have been nice to know that 5 weeks ago. Still puzzled why they didn't communicate with me and thus the low review. I have to say that I thought they were really nice people, but obviously my business wasn't that important to them. So be it. But a little courtesy and honesty would go a long way when servicing a small community like Key West. Because of the later incident, I wanted to give them an F, but that wouldn't be fair. If you're lucky, have deep pockets, and the problem isn't complicated, they are okay. Just be aware. I thought I had actually found a reliable service, but that wasn't the case."

"We had an apartment that required a new fresh coat of paint and several miscellaneous repairs like wall patching and bathroom tile recaulking. They did a wonderful job. Quick, efficient and reliable guys."

"It was a fast and easy process. Techs worked very clean and did an amazing job. Thanks for the amazing service. Highly recommend"

"Had my AC serviced twice. The level of service is outstanding, and the prices are reasonable. I would strongly recommend this company."

"They were great. They were on time, quick, and polite. I'm very happy with their service.."

"Mark was very knowledgeable and respectful and was able to diagnose and repair our AC Issues. His services were also very reasonably priced."

"This business is family owned and provides incredible service! My experience with home repairs is minimal AT BEST. My point of contact was Nikolas Hernandez. He is bilingual and had no trouble communicating with my father. He talked us through the repair process and even introduced us to the technician, Robert Hernandez, who would be handling the installation. Robert arrived early for the installation, kept disruption at a bare minimum, and the parts of the house he worked in were even cleaner after he left."

"Excellent service and very professional."
