We reached out to Pharo when we decided to finish our unfinished basement. Pharo had done the HVAC work for the rest of our home so we reached out to them to add the additional duct work required. They came out quickly, gave us a quote that was really reasonable and were extremely thorough in their installation. The quality of their work really speaks for itself. Would recommend to anyone looking for HVAC work!

We came home yesterday about noon to find our furnace not working. We called Pharo and a service technician was at our door within a hour. The tech replaced a faulty part and we're up and running. I highly recommend Pharo Heating & Cooling.

Furnace went out overnight a few times. Called when Pharo opened at 7:30 and someone was at our house by 8:30. Serviceman was knowledgeable, friendly, and efficient. He was able to solve the problem quickly. Very happy with the service we received!
