"Great. I was out of state and my house and dog sitter called. My house temp, was 85! Look up Angie’s list. Called the business and explained the problem. They got the repair man out the next day...on a sun day!! My air was fixed by the repair man that day. My sitter said he was very nice .....price was great,,, I would have them again. This is the 2nd time I use Angie’s list."

"Prompt service with very little advanced notice. Technician removed old flame sensor and installed a new one in about 20 minutes. Pleased with technician and service, and will do business again them again if needed. Owner called to confirm service and sent a text with name and information about the technician before his arrival."

"The technician that serviced my boiler was Aiman. He was very professional, thorough and informative."

"The boiler had needed some replacement pipes as well as the solution to the slight smell of gas when near the boiler itself. Prior to calling for service for these issues, I had removed the majority of the damaged piping and purchased all new of what I was able to remove. I couldn't remove the bushing that attaches directly to the boiler or the nipple that attached to that bushing to save my life. On the night prior to the day of my appointment, there was a snow storm and time moved ahead. I had forgotten to move my clocks ahead that resulted in my arriving about 20 minutes late. The repairman was kind enough to not only wait for my arrival, but to shovel part of the snow from my walkway that leads to the basement. This guy is just great. He removed the fused together bushing and nipple in no time flat. It was amazing for me to watch. I had to pick up a couple more pieces of pipe for my job to be completed and we scheduled to continue after I did so. Luckily, The pipe I needed was in stock and he was able to return the very next day, he removed my bushing and nipple, installed ALL of my pipes, and provided and replaced my leaking gas line. MY BUILDING NOW HAS HEAT AND I COULDN'T BE HAPPIER!!! Now I have to have the other parts of the building repaired that were damaged from when the boiler had stopped working and a pipe had burst. You won't be disappointed if you hire Discovery Heating and Cooling. If I have another related job in the future, I will definitely call Discovery. Thanks again Discovery."

"Climate Master did a fantastic job servicing our furnace boiler for a seasonal tune-up. Chuck answered all my questions and offered helpful tips and explanation of how to properly care for the system. He was reassuring and explained that there were no problems when I wasn't sure if a sound I had been hearing meant something was wrong. Kimmie was pleasant and helpful when scheduling. Thanks, guys!!"
