"Paid a premium for a new HVAC system, and the A/C has had issues every summer since installation. Service calls have been frequent but only resulted in temporary fixes. Most recently, the system failed completely, and despite promises of follow-up and support, the company has been unresponsive and disorganized. Communication is poor, and I?ve been left without A/C during extreme heat. Very disappointed in the lack of reliability and accountability. Would not recommend"

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."

"Beware!! They quoted me one price but once they got there and I called their office the lady said it would be more. Then after multiple calls while they kept changing their story they refused to give me my full deposit back until they received a refund for the permit. I will absolutely never use this company. It was the biggest headache ever."

"Horrible customer service. Left a message and two online requests for a call back during the week. Did get back to me on a Saturday and charged a lot to come and attempt to fix my air. Was happy to see them (95 degrees)so I had no issue paying the exorbitant weekend fees during the first visit on Saturday. ( note this company advertises 7 days a week but omits reference to weekend costs on their marketing materials). Technician showed up and worked on our issue while multitasking others issues on the phone during our service but felt he had the fix…9 pm that evening our system froze up again and I made a call for help! The technician called me back and said he would come back on Sunday to “warranty” repair the unit. (Tech Dominik was very nice and was professional) I mentioned that if they were going to charge me the exorbitant rates again I would wait until Monday for service. I was told they were too busy and the next week didnt look good as they were so swamped. No choice…Warranty work, but have to pay extra? Tech came back out on Sunday…I had to cancel plans with family because this rework/diag couldnt be done during the week. Tech was here for a couple of hours and I had hoped that because of the company not fixing the first time and having to cut my weekend plan short the nice thing to do would be to not charge, at the least, all of the 1.5 rate. Spoke with an “ego” from the office (Will in dispatch) as I mentioned to the tech that I would appreciate a call from his boss…didnt have the courtesy to phone me but he did want to lecture me on the techs own speaker phone. What a horrible tactic. Rude and unprofessional. Long story short…use another company that respects its customers. Lots of great companies out there that would be appreciative of your business ! Lost me as a customer…will be forwarding complaint to all that are willing to listen and to the BBB and Trane."

"I called A1 when the company that normally services our HVAC system couldn’t get to our home for several days. A1 told me they could have a technician at our home later the same day. Not only did they get a tech to our home that day, he was there 2 hours prior to the estimated time frame. I cannot praise Gered Stovall, the tech that worked on our unit, enough. He quickly diagnosed that the unit was low on refrigerant and replaced it to get the a/c working, but he then worked to find out why the unit was low on refrigerant and while it was a fairly costly repair that couldn’t be completed the same day, Gered and the staff at A1 worked diligently to come up with an economical and viable solution. Gered was, professional, communicative, prompt and incredibly knowledgeable when it came to servicing our a/c and I would recommend him and A1 to anyone!"

Air Duct Cleaning questions, answered by experts

The EPA recommends duct cleaning only as needed—meaning routine cleaning is unnecessary. But if you suspect mold or other contaminants in your ductwork, consult a local professional to determine the best next steps.

Redirecting air vents will have a positive impact on your HVAC system’s performance. It will help evenly distribute air toward the center of the room and stop those pesky hot or cold spots. This is a much better solution than closing the vent, which can cause your HVAC system to work harder to reach the ideal temperature. 

Onions, peppers, fish, broccoli, and fried chicken taste great—but the leftover smells can be less than appetizing. Even if these foods are cooked perfectly, the odors they leave behind can linger well beyond the dishes being cleared and washed. Fortunately, you can use the same tips to get a burnt smell out of the house and remove stubborn food odors. In addition, make sure you’re keeping your fridge clear of odor-smelling foods for too long to keep the stench from invading other foods. 

You have two different types of air vents in your home: supply and return air vents. Your supply air vents are responsible for pushing air into your home. Meanwhile, return air vents draw warmer air back into the ductwork to condition it by removing the warm molecules from it. Both types of vents are necessary to a working HVAC system and a comfortable home.

Finding mold in an HVAC system is never fun, but the good news is you can clean it and send those spores packing. That being said, hiring a helping hand may be necessary to fully remove the mold and prevent regrowth. Professionals use specialized tools and cleaners, such as antimicrobial solutions and HEPA vacuums, to safely remove mold from ducts, coils, and other components. For small amounts of mold, homeowners can clean visible areas using a mix of water and detergent, but they must wear protective gear and avoid spreading spores.
