Residential or commercial, if it heats or cools your home or place of business, D&M Heating and Air Conditioning is here for you. We’ve specialized in servicing, repairing, and installing heating and cooling systems around Milwaukee since 1979.
Sometimes, that means diagnosing, repairing, or breathing life into existing systems. Sometimes it means recommending and installing new ones.
Often, our work involves a combination of the two – extending the life of an old system, while also planning the best time to install a new one.
Whatever your situation, D&M Heating and Air Conditioning will give you honest recommendations, quality work, and will always stand behind the work we do for your comfort.
After all, you don’t make it nearly 50 years in Milwaukee without taking care of people.
Happy Customers Leave Happy Reviews
We get lots of them. Here are a few of our favorites…
My furnace would not heat so I called D&M. In less than 2 hours, Alyssa called prior to arriving and then pulled up 10 minutes later. She quickly identified the issue and fixed it and then made sure things were working before she left.
Our air conditioner went out during a hot spell, they came out right away and by the next day we had a new unit installed. The installers were friendly and very efficient. We are very pleased with our experience with D&M Heating.
I jokingly told them: “I don’t speak HVAC”, but they were kind enough to teach me what I needed to know to be an informed homeowner!
