HVAC recommendations

Any suggestions for reliable HVAC contractor in South / Central Berkshire County?

I've had an issue with one of the larger contractors in the area Several months back so was hoping to see if there are any recommendations people could make. Reviews seem to be all over the place and the people we had used prior retired a couple years ago.

Looking for 2 things: 1- furnace repair, 2- small furnace & C air install
