This company agreed to install a specified brand and size of AC system in my home. After three attempts they never installed the agreed unit. I requested that they honor their "bullet proof" guarantees as promised in their advertising and sales pitch. They refused to honor any of their guarantees. Please don't make the mistake I did. We are out mare than $10,000 in this matter so far. Do research. Check with everyone you can. The guarantees are worthless. Please be careful. They are very slick. This is the worst purchase experience of my entire life.
