Most people immediately think of furnaces when opting to heat their homes. However, boilers provide a highly effective heat option, have a long life, can reach high heating efficiencies, and some types require little or no pumping energy. Boilers are an important part of a central heating system. They're a continuous closed loop of pipes carrying heated water (or steam) throughout your home.
You may have heard about ductless heating and cooling systems, but do you know about their advantages? The most common HVAC systems are central air conditioners and heat pumps that use ducts to deliver conditioned air throughout a building. Ductless systems are more flexible than traditional systems because ductless systems don't use ductwork.
On average, people spend 90 percent of their time indoors but don't know that indoor air can be two to five times more polluted than outside air. The US Environmental Protection Agency (EPA) has indoor air quality ranked as one of the top five environmental dangers to public health. It is linked to severe asthma and allergy development in children and to heart problems and lung cancer in children and adults.

This company is awesome. I truly believe they have the most professional team hands down. They are perfectionists, professional, clean, innovative, friendly and conscientious people. I honestly wouldn't trust anyone else with my HVAC needs but the Cool Sunshine team! Thank you Cool Sunshine crew for taking care of me and my family! A special thank you to Perry, Joy, and Mitchell Valentine!

The entire team at Cool Sunshine was amazing. We had an AC going bad so we had some time to schedule the replacement. Joy gave us 2 price choices for AC replacement, both aligned to what we had discussed. The week before the scheduled install, Joy reached out to confirm the date and workorder. The team of 3 installers showed up on-time with all the right equipment. Later in the day a manager stopped by to confirm the work was done right, all setup and clean up was completed, and that I was satisfied with the work delivered. Overall a great service experience.. Amazing teamwork at good price point

Cool sunshine did a residential AC installation for us and I can honestly say it was a great experience from start to finish! Joy and Ivy are awesome and very communicative and the installers were very professional and knowledgeable with all of my thousand questions , they also covered all the flooring from the front door all the way to the furnace area to keep the floor clean. I would highly recommend this place to anyone. They are personable and helpful with any concerns or questions you have and the prices for the service are very reasonable. I am glad to say that I felt comfortable spending

We loved this whole experience. First, the estimator, Joy, was delightful, giving us many options with no pressure sales. We were able to schedule the install within a week of ordering. The installation technicians were friendly, clean and very professional with a great mind for detail. I would highly recommend this company! We will be using them for our furnace replacement soon!

Cool Sunshine Heating and Air Conditioning was very professional, honest and easy to work with. They installed two AC units in our house. They were very careful and covered the floors in the areas they were working. They also did an excellent job working around some tight landscaping without damaging anything. I will definitely use them for any future service.

I have used cool sunshine services for many years. There is no need to search for another company when this one has always gone above and beyond on the quality of their service.
They are always prompt and professional and get the job done first time around. And with a smile.
Thank you
I would recommend this company to anyone who wants the work done right.

HVAC is tricky as a typical consumer - you don't deal with it much and when you do it is usually because there is a problem. It can be hard to know who to trust and what to expect in terms of service and pricing.
I was having furnace issues and the Cool Sunshine team was recommended to me by a friend. I am very glad I followed up on that recommendation.
The technicians were professional and friendly and did a very thorough job of diagnosing the issue and took the necessary time to discuss options with me.
Ultimately I needed a new furnace and Cool Sunshine was able to get it installed within

Extremely professional, reasonably priced and punctual. We were referred to Cool Sunshine after getting 3 other quotes and Cool Sunshine came in 1st by a few hundred dollars to the second lowest bid. No sales pitch, no sitting down at the table for 1hr to sell you what they are providing. They knew what needed to be done and did not waste our time trying to up-sell. Being a homeowner who is fairly skilled in home repair, I know better than to just go with the lowest cost. I tend to look for the signs of professionalism, and also have family in various trade professions, so their opinion is factored

I've been using them ever since they put our heating and cooling systems into a new build 6 years ago. Having them out twice a year to do preventative maintenance the engineers who came out were courteous, friendly, and always on time.

The front office person, Joy, has always been accommodating to our timing needs and worked with us to have services done. This week she went above and beyond to fit us into a packed schedule on Friday to have an engineer (Israel) come from Parker to Castle Rock to handle our urgent AC need. Israel arrived on time and worked efficiently to analyze our issue

I use Cool Sunshine for all my heating or a/c maintenance and repairs. My neighbor has them take care of her swamp cooler twice a year. Cool Sunshine has great staff including Joy and Jesus who have been with them for many years. Give them a try and see their vans with the penguin graphics on the side

Use this company!!! You are going to spend a CHUNK of $ on the single most important element of your home's infrastructure, the heating & cooling system, and you DO NOT want to screw it up. Right? So start by going with the best integrated furnace/ac system available...Trane. Lots of cheaper systems available, emphasis on "cheap".
Trane is the head of the class in performance, reliability, warranty.
And Cool Sunshine is the company I selected (after an extensive, exhaustive vetting) to install my decidedly cool, swanky system. Professional and competent to be sure. But

I would highly recommend Cool Sunshine Heating and AC for the following reasons:

1) Our furnace died in February after 24 years of service. I researched Heating and AC units. I selected Trane based on my research. I went to the Trane website and selected two Factory Authorized Installers, one of which was Cool Sunshine.

2) Cool Sunshine was able to meet in less than 24 hours. Very timely. Joy evaluated the existing system, looked at the layout of the house and asked questions about warm and cool areas within the house. Based on her evaluation, she made a recommendation that made sense.

After reading Jasmine B's review, I wonder if we are reviewing the same company because our experience with Joy was quite the opposite before we decided to part ways with the company. We had communication issues and calls/messages were frequently not returned leading me to file a BBB complaint at which point the company stopped communications altogether. Our experience with the front office was bad enough to warrant one star.

A friend of mine referred this company to me when my heater went out. I was so worried that we might need a new furnace. I called and they had someone out that day. Our furnace has been running like a dream ever since. Our electric bill even dropped because the furnace was running more efficiently.
We liked the service we received so much that we decided it was time to install ac. Once again, they did a great job. We received quotes from 5 companies. They werent the cheapest but they were very reasonably priced. Joy was amazing to work with as was everyone i encountered from this company. My
