Today Derrick Garcia a service specialist with the Climate Control company from Glenwood Springs CO came to our house for an annual maintenance on our two furnaces and our built-in humidifier. When I read the work order and notes I was impressed with the thoroughness of the work that he did. He was also pleasant and courteous. I commend Climate Control for hiring and training a quality young man like Derrick. I can recommend without reservation Climate Control for your furnace needs. David Nordin Gypsum, CO.
