Everyone we dealt with was friendly, courteous, and professional. We called to schedule a consultation, and they sent someone to meet with us within 2 days. They provided us with an estimate for 3 different types of units, and gave us information for applicable rebates. Once we decided which unit to purchase, they were able to complete the installation the next week. The installation took 2 days because of the amount of work required. The technicians arrived exactly when they said they would, worked all day, barely took breaks, and were very professional. They used drop cloths and shoe covers to decrease the mess, which I appreciated. When the work was complete, the service technicians showed me exactly what they had done, and explained the digital thermostat. A few weeks later, our old unit started making strange noises. I called the company, and they sent a technician that afternoon to come & inspect it. He determined the source of the noise & made the repair in about 15 minutes. This is an excellent company that clearly knows what they are doing. If you are looking for quality installation of equipment and first-rate customer service, then you need to use this company.
