VERY SATISFIED AND WILL USE THEM AGAIN

I had McMaster install an air cond. in a rental home in may 2015 and they did a good job. I have waited until now before writing a review as i wanted to see if we had any problems. Through all the heat this summer not one problem. I am very satisfied and will use them again.

DID THEIR BEST TO GET IT FIXED IMMEDIATELY

They put in my new units, 3 years ago. When the fan went out, in a hot spell, they did their best to get it fixed immediately.
