​"I am a landlord and also a MN Licensed Builder and Remodeler with over 20 years in the business. I have been using MD's Heating and Air for several years now for a multitude of projects and refer Mathias to all my friends and family who need help with their mechanical systems. He is always prompt to return calls, he is clean, does the work correctly the first time, finds time to get to you right away in the case of a complete failure, has great pricing on new systems as well as for repairs. What else can you ask for in a mechanical contractor? Very highly Recommended!!!"

​"We have been working with MD's Heating and Air for a couple of years. He is very knowledgeable and the prices are reasonable. We had MD's Heating and Air do some duct work for us recently, and we are very pleased with the results. In addition, it is good to know that we can call him if we have any questions."
