At M&S HVAC, we’re more than just heating and cooling technicians—we’re neighbors, problem-solvers, and committed professionals with a passion for keeping our community comfortable. Founded and led by Moses Waldner, our team is proud to serve Tea, South Dakota and the surrounding areas with top-tier HVAC solutions and hometown values.
M&S HVAC was built with a simple mission: deliver dependable, honest, and high-quality HVAC services to homes and businesses in South Dakota. Moses Waldner started the company with years of industry experience and a desire to provide personalized care that large, corporate providers often lack.
We understand how important it is to have a heating and cooling system you can trust—especially in our unpredictable Midwest weather. That’s why every installation, repair, and maintenance visit we make is done with precision, transparency, and your long-term comfort in mind.
Whether it’s a small furnace repair or a lite commercial HVAC system installation, we approach every project with integrity and a commitment to excellence. It’s not just about doing the job—it’s about doing it right.
When you choose M&S HVAC, you’re not just hiring another contractor—you’re choosing a team that truly cares about your comfort, your time, and your trust. Let’s build a lasting partnership, one service at a time.
