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 of shipping issues with this company. Ordered an ice maker installation kit on 10/10/25. Shipping was due no later than 10/20 according to company and FedEx tracking. FedEx tracking showed the package at their facility for 8 days without moving beginning on 10/15. Called FedEx 3 times. Each time they said they cannot find package and I have to contact shipper. Shipper has to make a claim, they will not mark it as lost. Called Appliance Parts Pros twice. Each time they say FedEx has to mark package lost before they will do anything. They also state they have to wait 14 days from them before doing anything because of their contract with FedEx. I don't care about their contract, I want what was ordered and paid for.

We are a full service HVAC company serving Northern Colorado. We have NATE certified technicians. We are a Carrier Factory Authorized Dealer (CFAD). We realize that problems don't just happen from 9 to 5 and that's why we have 24 hour emergency service.

"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."

"I worked with Chizum and had a great experience. For my work, he requested a few photographs instead of sending someone out to have a look. He wanted to be sure that the bluish pipe entering the house was not the type that should be replaced before the work was done (it wasn't). He explained that they would not guarantee their work if it was and that they do not do the replacement work anymore. He was very thorough and knowledgeable - super helpful! Chizum estimated the work would take one hour (which it did exactly) and that if the pipe turned out to be the wrong kind he would not charge "a huge amount" for the service call. I plan to use IPS going forward!"

Heating and Air Conditioning questions, answered by experts

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

While spending money once or twice a year to tuneup your AC and furnace might seem like a waste of money, think again. The cost of HVAC maintenance is far less than the cost of replacing your furnace or AC unit, regardless of the type of HVAC system you have. Paying this smaller fee now will help you avoid paying much more significant costs in the future. Not to mention, having a serviced AC and heating system will help keep your home comfortable, no matter the season.
