Pro-Tech HVAC Home replaced our upstairs HVAC system. There were fantastic. The face of Pro-Tech is Chris Mahoney, a true professional who was there from start to finish. When developing the estimate, he performed a Manual-J calculation to verify the size of the unit, and checked the flow at all of the vents. He didn’t try to upsell equipment, and gave me a very reasonable price for three potential systems. He was the only one who didn’t pressure me to make a decision on the spot, and he emailed me all of the information within a day of our appointment. We went with the least cost, American Standard. When we placed our order, Chris was actually able to procure the higher-quality Lennox system for the same amount, so we went with that unit instead. Chris and his crew arrived on time, and stayed until the job was done. When they realized the old thermostat was incompatible, Chris bought a replacement one and hooked it up at no additional cost. I highly recommend them, and I will use Pro-Tech HVAC Home for all of my heating and cooling needs.
