Our customers have recommended us to your neighbors and local businesses for years because we are the better choice. You can find out more about our history by clicking here.

We serve a 10-mile radius of Mokena, to ensure that we arrive at your home or business quickly to solve your problem faster. We can provide same-day, 24-hour emergency service and we’ll always do the job correctly during our very first visit. Our office hours are Monday through Friday 8 am – 4 pm.

With a customer satisfaction survey ratio of at least 95%, we meet the rigorous requirements and standards to earn the Customer Care Dealer distinction. We achieve this level of satisfaction through our stringent employment practices. Our technicians’ quality of service is the most important product we offer, so we are very careful about who we hire and how our staff is trained. Our technicians undergo a thorough background check prior to their employment and require random drug and alcohol screenings. Each technician attends continuing education classes in the spring and in the fall of each year.  You can meet our team by clicking here.

You’ll like our upfront pricing, providing you with a complete picture of the problem and the cost of its solution before work ever begins. Our technicians are not paid any commissions to sell either parts or services, so you can trust that all recommendations are based on solving your problem in the most efficient way possible.

Maertin Heating and Cooling is a member of the Mokena, Frankfort, New Lenox and Manhattan Chambers of Commerce, demonstrating the commitment we’ve made to our community.

With the higher standards of quality we set – and meet – for ourselves, you’ll get better quality products, service and repairs, whether residential or commercial, all with a one-year warranty on all parts and labor.
