Sherrye Fisher

I have had two other companies as well as an electrician look at my air conditioner and the two companies both just changed my filter on the furnace. Cooper listened to all of the complaints and concerns and immediately went to check it out. I will have absolutely no hesitation on recommending your company to my friends and family.

Mark & Laurena Schmidt

We are extremely impressed with your employees and your company’s work ethic. Thanks for such a great experience with your company. Your company will definitely get high ratings and recommendations from us.

Jonathon J. O’leary

Your servicemen were kind enough to come out to our house first thing in the morning and fix an air conditioning problem. His demeanor was friendly, professional, helpful and when I offered him a small tip—he declined it! He just asked that I pass the word about Cooper Heating & Cooling among any friends and neighbors—NO DOUBT!

…customers appreciate prompt, reasonable, friendly service.

Michael R. Hart

Your crew was very professional and did a great job. A job that might have taken a day and a half was completed in about 6 1/2 hours. More importantly, it was done correctly and left me nothing to clean up.

Timothy Burke

I want you to know that I appreciate the way you take care of your customers as well as the strong ethics practiced by your service team. Thank you very much.

Linda A. Stehle

I returned home from work, I realized I had no heat. We were having a snowstorm that day, and the roads were a mess. I called your company and they were very honest with me, stating they could not even guarantee to repair my furnace as the brand name is Armstrong and they were not sure if they would have the part the furnace may need. They recommended that I try and contact an Armstrong repair service person … When I did, the call out fee and the timeframe were very unreasonable. I called Cooper back and they said they could be out in a couple hours. He was very honest regarding the warranty of the circuit board he replaced. Excellent customer service is fast becoming a thing of the past. I have and will continue to share with everyone I know the excellent qualities of your company employees.

We do not believe there is any other provider for heating and cooling in the Denver Metro area. Please share our name with anyone requiring a reference. WELL DONE!

Nina Beeson

This is just a letter of appreciation for the professional courteous technicians that arrived at my house to install an air conditioning unit. Due to the age of my furnace and a bad schematic it took some time to get some problems solved. Your technicians were very determined to get the installation complete. I find these employees are an asset to your company and appreciated the information they offered.

Charlotte A. Seaton

I truly appreciated the information on how an air-conditioner works and what measures can be taken when it doesn’t work…his helpfulness was genuine and insightful; and he was willing to take the time to explain the fundamental workings that an amateur knows nothing about. He truly is an asset for your company and very knowledgeable.

Daniel P. Perron

We are very pleased with the completed product/installation of our AC & air cleaner. Even more so, we are pleased with the service, knowledge and integrity of all Cooper representatives we have dealt with along the way (I think we dealt with 10 or so different individuals). Since our first contact we have been comfortable with the decision., and have thus far given recommendations to six friends, neighbors and employees of my company. At least one, Chrissie Thompson, has bought a furnace from Cooper. Look for more business from Susan in the days & years to come.

Rosalyn Cass

I liked that there were no surprises. What I was quoted and informed about did not change. Cooper was true to their word. When there was an inspection issue, Cooper was out the next day and spent three hours fixing the issue. I cannot believe that there are still companies out there like this that give you a promise and deliver on that promise.

Dawn Sanderson

This note is to thank you for the prompt, efficient and courteous service that I received from your company during the purchase and installation of my air conditioning system. Your technicians are to be complimented for their courtesy and the pleasant manner in which they performed the work. It was a pleasure dealing with you and will certainly refer you to friends and family.
