I selected Coretemp for this project mainly because Richard (the owner) is very knowledgeable, has good experience with the systems I preferred and he explained clearly the installation options and process.
The crew showed up and completed the installation according to the schedule; they accomodated a special request I had and left the site clean.
There were some minor tune-ups required after the installation and Richard personally took care of that in a timely manner.
Coretemp helped with the registration and rebate paperwork and I can also say the communication with the company is very good (swift replies to e-mails by Janice).
Overall a good experience and I would recommend giving them a shot when looking for a system.
