Supporting the Loveland Community

As the first home services partner of Children's Miracle Network, One Hour Heating and Air Conditioning is working to help children in local hospitals. Just as we strive to provide comfort and service to our customers, we are excited to extend that goal toward patients served at children's hospitals in Loveland and beyond. Children's Hospital of Colorado is a part of the Children's Miracle Network, and we're thrilled to support the children and families treated by this hospital, right here in our own backyard.

Every dollar we raise, with your help, will go to support research and training, purchase equipment, and pay for the care of every child who needs treatment. More importantly, all money raised in the area will stay right here in the community and benefit the children at Children's Hospital of Colorado. Call us to learn more!

Proud partners of the Colorado Eagles

One Hour Heating and Air Conditioning is extremely proud to partner with the Colorado Eagles Hockey team. At One Hour we share the belief that sport can play a positive role in the community and in the health and welfare of the young people in our town. The Colorado Eagles Hockey team has been a unifying force to our local area, and we will continue to give our support.
