Randy knows his stuff. He provided a complete solution for this house, 5 heat pumps / 8 zones, all working perfectly one year later. A+++ Highly recommend.

On time, courteous, respectful, knowledgeable. Willing to go the extra mile to do the job right. Tom has always been right there when I had an emergency.

Knowledgeable, Professional and great to work with. They know what the issue is and how to fix it. They are not trying to sell you a new unit unless you really need one. They are like that courner mechanic you trust and keep going back to

We were not able to stay there due to scheduling conflict, but in working with us he was very accomodating and conscientious. Will definitely contact him again.

Tom did a great job putting our new heater in last year. His team is trustworthy and considerate. I was very comfortable with them in the house while I went to work! I highly recommend Del Fera & Son Heating and AC!!
