Impressive was one of 3 companies I invited to discuss replacement of gas furnace and air conditioner, and it was by far the most engaged and informative, taking time to fully explain benefits and costs of options. Impressive's prices were more competitive, and I believe my high efficiency selection is excellent value for money. I was provided a clear timeframe for installation. The 2 technicians arrived properly masked and on time, worked safely and completed the installation as planned. One technician patiently answered all my follow-up questions and showed me how to program the new thermostat. I am delighted with Impressive's excellent and personal service and highly recommend them.
