We were completely satisfied with our experience of having a furnace, central air, and a humidifier installed in our home by Holland Heating. TJ, Ted, and Andy "2" were courteous, efficient, and worked hard to do the installation in an excellent way, even going beyond what we expected. They were careful not to track on our carpet and cleaned up after themselves. They were friendly and kind. Doug, the salesman, explained the products and services very well. Overall this was the kind of experience every homeowner hopes for.
