JM Heating and Cooling

With more than 25 years of experience under our belts, it’s easy to see why Slinger and Hartford homeowners keep recommending us to their friends, family, and neighbors. We take pride in getting the job done right the first time, whether you need your furnace, air conditioner, or indoor air quality products fixed, installed, or maintained.

Whether you need a furnace repair or a simple air conditioner tune up, JM Heating and Cooling is your one-stop shop for HVAC service. Since the day we opened in 2009, it’s been our promise to deliver quality, reliable home comfort care at an affordable price, and we’ve come through on that pledge time and again.

After years in the Army, Jim McNall joined the heating and cooling industry, learning how to expertly repair and service furnaces and air conditioners of all kinds. He branched out on his own in 2009, using his expertise and hard work ethic to open JM Heating.

Today, Jim and Austin help people stay comfortable in their homes, helping them problem-solve, troubleshoot, and repair any home comfort issues that arise.

At JM Heating, we understand that any time a furnace or air conditioner goes out, it’s an emergency. That’s why we offer 24/7 service, where standard rates apply whether you call within “business hours” or not. Your comfort comes before everything else.
