I arrived to bid a system for replacement. I first spoke with the homeowner and found that he already has other bids to replace the system. We inspected the system together and compared bids from the other company’s. His favorite bid was a Armstrong system 20 seer 10 year parts warranty for 12,680. I bid a 16.5 seer carrier system with the same 10 year labor warranty with a one year labor warranty and free first year maintenance plan to keep the system clean. I offered to install my carrier system for the same price as the arm strong with all my same guarantees and the homeowner wants to stay with the Armstrong 20 seer system.
