Colorado Home Services
CHS is a local, veteran-owned licensed electrical contractor that provides full residential electrical services with deep expertise in whole house fans, attic fans and ventilation, sun tunnels and skylights. We have been providing the most environmentally friendly, cost-effective and energy-efficient home cooling and daylighting solutions in Colorado since 2003. We pride ourselves on delivering an un-matched customer service experience. From pricing to install, our team is dedicated to earning your trust and finding the best home cooling and daylighting solutions for your home, no matter what! Offering industry-leading brands and a wide range of products suited for any home, we are Colorado's premier home electrical, cooling and daylighting provider.
"When it comes to home services, CHC sets the bar exceedingly high. They installed a whole house fan that dramatically reduced the amount I need to run my AC. They were on time, professional, and completed the install faster than expected (~3.5 hours). They cleaned up after and took some time to train me on the many ways I could use the fan to save energy and improve comfort in my home, some of which I wouldn't have thought of. In an industry where low expectations seems to be the norm, to say that CHC exceeds expectations is an understatement."

"On 3/13/19 we woke-up without any heat so I put in a call to Paradise Heating right on the dot of 8:00 and who should answer the phone but John (the owner). He understood my anxiety because there was a big snow storm (and cold temps) about hit all of CO. John scheduled us in right away for a call that morning. The problem turned out to be a quite a tricky one that he was able to figure out ... but ... he was going to have to make a trip downtown to pick up some parts RIGHT AS THE SNOW STORM WAS GATHERING STRENGTH. John gave me a call once he got to the supplier because it took him longer than expected (due to some traffic lights failing) and gave me an update on when he expected to be back at my place. By the time John got back there was already inches of snow onthe roads and it was getting slick, but, John didn't hesitate about continuing with the repair and it was another hour before he had fixed our furnace and he could head home. This was customer service that went beyond what any customer could expect. A big thanks to John!"
