My furnace was on the fritz, so I contacted Stewart Heating and Air. This was my second time doing business with them and once again, their service far exceeded my expectations. Angelica, Kathy--- and especially Christina--in Customer Service were superb. Communications were thorough, accurate and timely. Don the Service Technician showed up on time, was personable and professional, quickly diagnosed the problem, and ordered a replacement part which arrived the next day. Kathy in Customer Service squeezed me in for an appointment the following day to have the part installed even though their schedule was full. Bravo for that extraordinary feat! Don came back and expertly returned my furnace to perfect working order in no time at all. He was cheerful, helpful, and gave me a very reasonable price. Invoices were promptly emailed to me including my applicable $40 off coupon. Truly 5 star service with excellent value from every single member of the staff. My congratulations to Bill Stewart for hiring exemplary employees who clearly take pride in their work. I am sold and will definitely invite you back!
