"Overall a good experience, but a bit of a hiccup at first. Made an appointment for next day (Friday) service/diagnosis of a dead central AC unit , but the tech never arrived- when calling the office, they said the tech wouldn't answer his cell, so they rescheduled for the next business day (Monday). On Monday, the scheduled tech did arrive, and provided quick diagnosis and service. Now the AC works better than it did when I moved in last year! It seemed pricy, but I'll admit that I haven't had to service the AC before, so I'm not sure how it compares."

"My electrician from Cotti-Johnson HVAC was a master electrician. If you get him, you are getting the best. I went with the most expensive work package of the 3 that were presented. First off, it was pricey. I knew that going in. I want Cotti-Johnson to understand that I am serious about a working relationship with them. I feel I have done that with their electrical department. Now, if I need their plumbing or HVAC service, our relationship can build off the first experience."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."
