WATCH OUT, It seems as if this company keeps changing their address. They have Mohegan Lake, Yorktown, and when I called, they told me they are now in Thornwood. Review Should be ZERO STARS, but page will not allow it! Made an appoint almost a week ahead of time. Had to take time from work, then they call me to get home earlier, so I get a substitute for my class and leave earlier and RUSH home. As I am waiting I get a call saying "......sorry for such short notice, but we have to cancel your appointment." I didn't let them finish, and told the person to forget it. Their loss, I was going to have $10,000 to $15,000 worth of work done. New high efficiency oil boiler, new indirect water heater, all new plumbing in the mechanical room, and two new zones added because I adding a big room/garage to the house. Sloppy and inconsiderate way to do business. My next reviews are now going to Google, Yelp, Yellow Pages, BBB, and Facebook!
