We had Alaskan replace our old AC and heater units. We shopped around and they were the only ones who took into account our specific house, rather than just giving us the standard option. They added a return and relocated the outdoor unit, to give us our patio back. The additional charges for those issues were reasonable. There was a problem the first day that knocked out our cooling, but they came back out right away and got it running right. We just had our first maintenance check 8 or so months later with a professional service tech. We have had no problems with our nice new unit or the included thermostat since it was up and running correctly. We are very glad we chose Alaskan.
