Cooper won my business through their install of a new Lennex HVAC system in my home. I've had them out for service and maintenance and they are exceptionally professional and work hard and are courteous and their work standards are the highest that I've run across. Then I learned that they had started a solar program and not only did their system beat out the competition for price and quality, but I know that Cooper H&A will be around tomorrow and years from now for the servicing of the systems they install. That IS the most important thing that I can think of when dealing with a contractor. Service for the products they sell and install. Nothing else matters.
