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."

Customers say: Quality work
"Hiring this company was the biggest financial mistake of my life! If you care about your home don't hire this company. The only time they cared about me was just before I paid them? They wouldn't stop calling??? After they got their money I didn't hear from them much? It took this company over a year to fix hail damage on my home. After not hearing from them for months I called KKTV call for action on them. As soon as the news reporter called them that day they contacted me and showed up to my house to work. They would recognize my phone number and not pick up? I would literally have to use my neighbors phone or family phone tricking them just to reach someone in their office? The owner tries to point fingers at the insurance company and he even blamed me for not knowing what the insurance company was actually covering? I posted a few pics showing what 27k can't fix/do? But you can clearly see in the pics that they failed at replacing specific boards directly impacted by hail. Instead they glued and painted over them. The best part about this ****** experience was the moment they left my home for good! Lesson learned!"

Steve is the sole proprietor of True Check and is available seven days a week for your service. I accept check, cash and credit cards for payment. Book an appointment through Angie's List and receive 10% off. And $ 25 dollars for referrals that turn into jobs.

"Steve is thorough and gave us an excellent, detailed inspection on a home in Colorado Springs. He saved us a ton of money by locating serious issues with that home, and we have hired him for another inspection on a different home. He is very knowledgeable, nice, and easy to work with. We will not be able to be present for the second inspection, but I'm confident in his work and recommendations. We had inspection, sewer scope, and radon."

"They did an amazing job. Showed up, did it and went above and beyond. I am a big fan and wouldn't bother to call another after this experience. They just plain rocked it! My attic had some insulation but not anywhere near enough. I was able to feel an amazing difference the first night. I would be willing to bet I recoup the full cost within one winter!"

Energy Efficiency Auditing questions, answered by experts

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.

Energy-efficient windows cost more than other window types, but they can help you save on your monthly energy bills, get you some breaks on your taxes, and even increase the value of your home. According to Michael S. Regan, Administrator of the U.S. Environmental Protection Agency, when people invest in green upgrades like energy-efficient windows, they save energy, money, and more.

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.

Yes, advising on models that save electricity and reduce utility bills.
