We had Eco Air install a new HVAC unit to replace on old system. The old system was a heat pump, and we replaced it with a gas furnace. The installation crew was efficient, got the job done timely, and the installation was top notch. They left the basement cleaner than when they arrived. When the gas company arrived to check the new system for any leaks, the field tech stated that the gas line install in the house to the furnace was the best he had ever seen. Excellent job, crew and company.
