Scott of Oiltech was the knowledgeable and experienced heat pump installer that we were looking for. He answered all my questions and with his team he directed the installation with professionalism. And we love the high efficiency unit he recommended, rated to -15 degrees. Instead of alternating on and off blasts of cold air like our old AC, the variable inverter technology provides comfortable even cooling. And so far we're using about 25% less electricity, reducing our carbon footprint and saving money. More comfort, less cost, and better for the environment - a win win. read more
