Cool Sunshine Heating and Cooling did an excellent job installing our two A/C units
Air Conditioner Installation in Denver, CO, 80224
“We purchased a furnace and air conditioner from Cool Sunshine in Oct. of 2020. They were very professional and were able to complete the installation quickly. We started using the air conditioner in late Spring of 2021 and discovered a problem. The Cool Sunshine folks responded quickly, found the problem and fixed it. This issue was even covered by the warranty. We ended up getting some landscaping done and had to have Cool Sunshine move the air conditioner out and then back into place. Even though this was one of their busiest times (with 90+ degree days), Cool Sunshine fit us into their schedule so we didn't have to go too long without our air conditioning. The representatives that came to do the work were courteous, knowledgeable and kind.”
