Where it all started
JML Heating & Cooling was founded in 2007 by Jon Leonard with a clear, simple objective: deliver dependable, high-quality HVAC service that homeowners could actually trust. From the beginning, the company was built on straightforward values—do the job right, stand behind the work, and treat customers with honesty and respect. There were no shortcuts, no gimmicks, and no excuses—just solid craftsmanship and accountability.
Over the years, JML Heating & Cooling has grown through hard work, consistency, and word-of-mouth referrals from satisfied customers. By focusing on reliable repairs, professional installations, and long-term solutions instead of quick fixes, the company earned a reputation as one of the most dependable HVAC providers in the area. Every system serviced or installed is treated as if it were in our own home.

Today, JML Heating & Cooling is recognized as a trusted, local leader for heating and cooling needs, serving homeowners who expect quality workmanship, clear communication, and reliable service year after year. Our commitment remains the same as it was in 2007: keep homes comfortable, systems running efficiently, and customers confident they chose the right HVAC company.
