"One Hour Heating & Air has been servicing my HVAC system since I moved to Fort Collins four years ago. Greg Nieves is excellent. He took time to answer all questions and went out of his way to offer suggestions and make sure I understood everything.. This company is totally competent although their prices seem a bit high. However, their service is great and worth the price since I've never had to call them back with a complaint."

"I signed up 3 years ago to the Swan Club, which includes yearly inspections of our furnace, ac, and plumbing. Mark recently inspected our air conditioning system. After purchasing an HVAC system from Swan, we joined the Swan Club, which includes yearly inspections. Yesterday our service technician was Mark. He was extremely thorough and professional, and and walked us through the whole system with pictures and comments. He could not have been more helpful. Thanks Mark"

"We had been looking for over a year for someone reliable to do a fairly small job, but couldn't find anyone until we found Monroe Construction. Kenzie was professional, considerate in keeping us updated with how far out he would be until he could start work, was extremely diligent in minimizing the mess and potential damage to our property (there was NO damage), and was quick and efficient ient getting the job started and finished. We would recommend Monroe Construction to everyone, and we would hire them again in a heartbeat."
