Rock Heating and Air came to our home to fix our 20 year-old gas insert fireplace. Is was filthy and inoperative; and a tech from another company told us it was un fixable. A Rock technician came over on 2 days' notice and had everything cleaned and repaired in less than 90 minutes. I will be calling them back; and recommend them to anyone living in Castle Rock, Parker, Lone Tree, or South Suburban Denver. Thanks, Rock!
