Major replaced my original townhouse heating and cooling system with Carrier products in early May 2014. Everyone I dealt with–from the estimator, to office personnel to the installers–was first rate. I learned a lot about heating and cooling from Major, as well. There were some minor issues that needed tweaking after my installation and Major was very responsive. They did whatever was required to remedy little problems. In fact, I felt that Major personnel went above and beyond in their responsiveness and diligence. This is one company that sticks to it mission statement. If you want quality products and a job done right, with respect, choose Major!
