Thankyou
Thanks to Tanner and Alai for their work, and thanks to Darren for his quick response to my request for a quote.
Dunn has an excellent team.
I just had a new York furnace and heat pump installed by Dunn Heating. Alex and his crew did a great job on the install! They installed the heat pump off my deck (where the AC had been) and into a much better spot beside my house and the thermostat to a far more convenient location. The whole team was very professional and cleaned up thoroughly after getting things set up and tested. I would highly recommend Dunn Heating and Air Conditioning.
