Overall a good experience for a furnace installation. not a bad price either. The only problem I had was flooring around the furnace needed to be fixed and some extra cleanup.

My husband and I had our air conditioner and furnace replaced by this company. The price was great and the service was outstanding. Our technicians, Tate and Reed, were friendly, knowledgeable, and professional. These highly skilled individuals took the time to explain not only the process but gave us the customer service we needed to understand how to utilize the systems. We are very much appreciative for their assistance and attention to all of the details. Great company and I would highly recommend these two individuals if you want work not only completed in a timely fashion, but if you want someone who can explain the product, and who will take the time to provide true customer service. Thank you very much to all who worked so quickly on getting our units and having it installed within the week!

Absolutely a great company to work with from all aspects. We had a large project to replace both the furnace and central AC systems, and also replace the main ductwork to create separately controlled ‘zones’ for the first and second floors. With the old system the second floor was always too hot in the summer. Through research on my own I had already decided on the highest level Bryant ‘Evolution’ units for both the furnace and AC and for the new zone control. The project was too large for the contractor we had been using to service the old units, so the search was on for a factory authorized Bryant dealer to install the new system. The choice of Square One was easy. Steve the owner came for the estimate, super knowledgeable about everything with the Evolution system including the details of the zone controls, and he prepared the proposal for us on the spot. I had originally intended to go through the usual hassle of getting at least three estimates, but I already had a ball park idea on the cost from my own research and after meeting with Steve there was no need to look any farther. Also we had a special request to relocate the intake/exhaust pipes of the old system to a difficult new location because we didn’t like where they exited on the side of the house, and Steve was happy to accommodate the request. I thought early September would be a good choice for the installation since would we probably would not need either the AC or furnace during the construction, but as bad-luck would have it a hot and humid wave of weather came right at the start date. Since the project was large it ran across four days and our crew of Jeremy and Josh did an outstanding job of minimizing the time that the AC was down, and gave us frequent updates on how things were going. They called every day when they were on the way, always came on time, friendly, knowledgeable, and super neat and orderly with all of the piping, ductwork, wiring and general work area. Co-owner Lee and Shaw came to finish up the intake/exhaust (on a Saturday) and did a fantastic job also. Also they prepared all of the paperwork for the multiple rebates that were included, and Erika and Mary in the office are always friendly and super responsive in answering our questions. The Bryant Evolution system has been great also, the hot and humid week turned out to be a good test for it and it performed excellently. The house has never been so comfortable upstairs prior to this system, and the new ‘dehumidify-only’ mode is great for the humid days without high temperature. Overall working with Square One was fantastic and greatly exceeded our expectations. They have all of our HVAC business from now on and we would highly recommend them to anyone.

Thanks Square One!
