I called Carlson and they were able to schedule my immediate appointment request. Carlson came over and after trying to save the air conditioner by replacing a part, the unit was pronounced dead. He called for the replacement cost and I asked for pricing on one size bigger, after we decided we need a larger unit, he order the replacement air conditioner for next day installation. He arrived exactly on-time for the appointment and increased the air conditioner capacity to fit the actual size. The appointment was finished under the estimated time and they were very courteous through the entire experience. While replacing the air coil, Mike showed me the location for the furnace and humidifier filter allowing me to change it myself. After replacing the air conditioner and removing the old one — he made sure that I had the information needed and made sure that if we had any questions to call his office. Great service and great/honest serviceman. I’ll not call anyone else for future HVAC matters and wouldn’t hesitate to only shop here when it comes time for me to replace other units. Second great round of service — last time was middle of winter and arriving home from out-of-town with no heat, he was wonderful replacing heater during the negative temperatures.
