We've been AC customers for several years, getting annual checks of our furnace and air conditioner under the package deal that also includes electrical and plumbing checks. This year our furnace check revealed a carbon monoxide leak problem, which required replacement rather than repair. The service tech showed us available options, and we selected an upgrade to our current configuration using a heat pump and furnace combination that should be a lot more energy efficient than our previous units. That was last Thursday. Jason, Micah and Nicolas came out yesterday (Tuesday) and installed the system. Their work was clean, meticulous, and complete, and they were a pleasure to be around. We were impressed by the whole process, from diagnosis to describing choices to ordering and installation, especially AC's ability to fix the major problem with our furnace so quickly. Can't wait for the cold weather to try out the new system, and then hot weather next summer to try out the cooling.
