When I started looking for a qualified contractor capable of installing central air in my 1895 three story home, I interviewed four contractors, including ECI which was the only (of the four) an unknown entity. I also did my homework on customer reviews and hands down ECI led the pack. I base this assessment on their knowledge of the product, quality customer service, working within my needs, and lastly the successful installation of the unit. On post installation follow up, they were very responsive when I had an issue I would definitely recommend the company and their staff to anyone looking for this type of installation.
