Recent Review: Decided higher efficiency unit would take too long to recover initial investment. I ordered a unit on Thursday and was told might have it next day (Friday) for a Monday install. I felt that was optimistic but pleased they would try. As expected, unit arrived Monday and was installed on Tuesday; to include being able to run the heater that night. Dave and his men removed my old external humidifier but ran out of daylight on Tuesday and had to install the humidifier the next day along with waiting for a warm afternoon to try the air conditioner. Crew was very enjoyable to work with; professional, and did a super job hooking up the humidifier drain to the condensate drain as well. Pine at Campbell's kept us informed about their arrivals and issues with the initial delivery slip (which did not surprise or bother us at all). Dave was willing to negotiate a bit on install and extended warranty price. Additionally, my last service call attempting to fix an intermittent heater issue was waived and not charged. Overall I am very pleased with the service, response and value for the money.
