After having my A/C looked at by a competitor they told me that the unit would have to be replaced. So I called AllCool to get a quote. The technician arrived right on time and evaluated the situation. Turned out that the thermostat was faulty and the ducting was not connected properly. I was advised to have the unit serviced and cleaned and replace the filters and thermostat. Within hours the A/C unit was working and cooling the office at maximum capacity. Excellent service and professional technician saved me thousands of dollars. Thanks AllCool for a job well done.
