"M&H saved our bacon. We had so many problems with a prior hvac sizing and install and they came out, *told* us the problems (which hadn't even been explained to us before) and gave us real options to fix the whole system. The house has never been more equally conditioned. Since then, we've had M&H as our regular checkup and inspector and they continue to deliver fixes that keep us running as needed. Thanks!"
