A/C was not working, called Aire One and had a technician come out the next day to diagnose, checked out the A/C unit, was ok, next checked the thermostat, was found to be faulty, asked for price on a new one, was $750.00 plus tax installed (Carrier Infinity System), called around, Aire One had the lowest price in the region, could not use any other thermostat so had it installed the next day, when it was all finished he went out of his way to check the a/c pressures outside to see how the system was working, and was told its running perfectly, while talking to the installer, asked him about whole house humidifiers and told me they had a special for the month, $425 installed, so had that installed as well, can say that from beginning to the end, it was a pleasure to do business with and will now call upon them when we require service in the future!
