"The inspection went well. It's after the inspection that is terrible. Telling me that I need these things done to improve the then charging an astronomical amount of money. I was willing to do some of the work. Sent a list of what I would like done and got a new estimate, with virtually had the same as the first. Only change was to eliminate some insulation.

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."

Currently we are booked until August 15, 2016. Cost is determined by the job. No travel charges. Service fee of $90.00 includes service call and diagnosis of system. Working rate $80/hr billed in 15 minute increments, parts are separate. We do not service Parker, Highlands Ranch, Lone Tree, and Broomfield or areas further out. We are also not servicing anything North of I-70 at this time. Thank you! License #14903 may contact through e-mail.

"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!"

Energy Efficiency Auditing questions, answered by experts

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

No, it isn’t necessary to have energy-efficient windows. However, if you care about your energy bill and making your windows more energy efficient, fixing any heat, UV, or air transfer issues is an excellent way to lower your bills and keep your house cooler in the summer and warmer in the winter.

As you look for the right soundproofing drywall for you, you’ll likely come across the Sound Transmission Class (STC) rating. This rating measures a building material’s ability to absorb sound. The higher the number, the better the material absorbs rather than reflects sound, reducing noise transmission. The STC rating for drywall doesn’t mean it’s for the panel itself—it refers to the STC rating for the entire wall system, including the soundproofing drywall.

Insulation is measured by R-value, which is the measure of a material's ability to resist heat transfer. The higher the number, the better the insulation. When installing insulation yourself, you need to determine the optimal R-value you need to keep your home warm in the wintertime, cool in the heat of summer, and energy-efficient all year long. Each inch of insulation provides between a 3 and an 8 R-value. The climate where you live plays a major role in what R-value you need and the price tag you might see in your insulation installation.
