We had several contractors come out to give us bids on this job. Both our upstairs and downstairs HVAC systems were over 30 years old and badly needed to be replaced. Danco was far and away the most professional and thorough of the contractors. I spent a considerable amount of time selecting a contractor, because with HVAC the skill of the installers far and away trumps differences between brands of equipment. We used a checklist from the Air Conditioning Contractors of America Association to score the various bids. In many areas, Danco was the only company to score any points. For instance, Danco was the only contractor to do a full ?Manual J? load calculation of our house. All the other contractors guessed or used shortcuts. This is the most basic step in assessing a home?s HVAC needs, yet only Danco took the time to do it right. If the quality of installation is the most important factor in the life and efficiency of your HVAC system, then how risky is it to hire someone who takes shortcuts on the obvious basics? I knew that as a clueless customer, I would not be able to assess whether they had taken shortcuts elsewhere. That?s why I went with Danco. Rather than trying to earn my business and trust with lame smooth talk or with lowball estimates (watch out for contractors offering you ?builder grade? systems in order to wow you with a ?low? price), they earned my trust by demonstrating their competence and skill right out of the gate. In the end, the price of their bid was competitive with everyone else?s anyway, once I sorted out who was cutting corners by trying to sell me builder grade equipment, skipping various parts of the job, etc. The installation team was efficient, polite, clean, and very professional. We were impressed. They tweaked a few things with the system until we were completely happy. There was never any argument from them ? instead, they did nothing but work hard to make us happy. Danco tested the airflow on our all vents before doing work and then retested afterward, so that we could see the difference. We were pleased with the results. After two months, I can say that our energy bills are now lower but we are keeping the house cooler and more comfortable than before. Previously, we didn?t bother to cool the upstairs during the summer since no one was using the upstairs bedrooms. Now with our baby sleeping upstairs, we?re cooling the second floor ? but enjoying lower energy bills! If you want a fair price, complete professionalism, and the assurance that the job is being done right for the long term, go with Danco. You may save a few bucks going with a contractor who is willing to cut corners, but you?ll be regretting it ten years from now when that contractor has vanished and Danco is still around. (As an aside, we also like supporting a family business that has been in Waco for over 30 years. It was neat to realize that the contractor who was helping us was the son of the owner, who started the company when the son was about a year old!). After all my research, I was convinced that Danco was the correct company to use if I wanted my HVAC systems to long outlive their warranties. During the process of the installation, Danco did nothing but further my trust.
