I'm happy with their service. They guys from Alpine Climate Control, Inc. are knowledgeable and have done a good job installing a radon mitigation system for me. This came about because a friend of mine had a high radon reading and I noticed that other houses close to me had radon venting systems. Initially, I got a do-it-yourself kit which showed high levels of radon in my house. Then I called Alpine. They were able to verify my reading and work with me on mitigation. It's still an ongoing process since my radon readings are a little bit higher than I'd like. I'll continue to work with Alpine Climate Control, Inc. on solutions. I give four and a half stars to Alpine Climate Control, Inc. for service. I'd rate them closer to five stars if they would get back to me a little bit more promptly. But otherwise, they've done a good job so far.
