"Called on holiday weekend when inside temp had reached 77 and AC would not come on. The tech called me within 5 minutes and arrived within 30 minutes. He checked all areas and determined the thermostat needed to be changed. Once that was completed it immediately came on. I have never been more satisfied with a service call and will definitely refer business to him and use him for all future work. Thank you Nelson!!"
