From a one-man operation launched on a Saturday in 1992 to a trusted Lincolnway tradition, Maertin Heating & Cooling has built its reputation on honesty, family values, and exceptional service. Founded by Jeff Maertin, the company grew through word-of-mouth referrals and a commitment to treating customers like family.

Today, Scott and Jennifer Maertin continue Jeff’s legacy by leading the company into the future with smart technology, energy-efficient HVAC solutions, and the same hometown values that have earned the community’s trust for more than 30 years. Now, a third generation is already preparing to carry on the family tradition.
