"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."

"The process was very smooth and the time frame that was discussed went off without a hitch. They even found multiple repairs that needed to be done and took care of those at the same time. Would definitely recommend them to anyone looking."

"Installers were prompt, professional. They took care, using drop cloths inside to avoid tracking dirt.
The system did not work properly when initially installed, so the following Monday, a repair technician came and performed diagnosis and trouble shooting, in contact with manufacturer's rep. He was able to correct the problem and got the system operating.
In addition, to address my concerns that the condenser unit might have been damaged, they subsequently replaced that part of the system to ensure reliability.
I was very happy with their responsiveness to my concerns.
I will use this company again.

"There were several problems with the space pack AC unit AC Engineers installed in 2016. AC engineers really stands behind their work. Their technicians are excellent. It took several visits to restore my system but AC Engineers did the job right. I live in a 100 year old house and repairs to my boiler and AC and other systems are a fact of life. AC engineers is a pleasure to work with and I have no reservations to recommend them to a friend."
