We only use Maertin Heating & Cooling and we cannot say enough about how happy we are with their service. They come out when they promise to be there so there is no guessing. The office staff and Scott helped us understand the details of the various options on their quote. In addition Scott patiently explained financing options. Their pricing is fair and competitive with other companies in our area. They came out immediately to solve an emergency, gave us options and then showed up on time to do our AC installation Allan was professional with the installation with Scott ensuring all our needs were being met. So in addition to being timely and knowledgeable, Maertin Heating & Cooling is an honest company to do business with. I wouldn't go anywhere else.

Called Maertin Heating on a Sunday evening when they were closed and they came out the next day. It was a simple fix on the furnace and Paul had the parts in his van. They were on time and completed the work. I would recommend Maertin Heating & Cooling to anyone!

Maertin is the best choice for HVAC needs in the Mokena, Frankfort, New Lenox area, by far. They are real and personable people that treat your house as their own and they have been the best for the 35 years that we've lived in the area. It goes back to our first experience on a very cold winter night when the owner himself came out and solved our gas boiler problem quickly and explained what we could do to maintain our system. Many times since that first experience, they have always met or exceeded our expectations, including a recent replacement of our AC system that was over 30 years old. Scott, Rich, Brett, Jennifer and all of their staff are the very best people you will work with to keep your home comfortable.

Rich was professional and friendly. He phoned prior to arrival and introduced himself. He proceeded to the attic and diagnosed the issue in short order' Bad blower motor.. He obtained the parts and reinstalled in a timely manner. Now i'm chilling out in a nice cool home. Thanks.

No heat in house. Maertin Heating were able to come and repair furnace same day. I have their maintenance contract which affords a discount on repairs. Recommend highly

Easy to schedule. Technician arrived the same day and on time. He quickly identified the issue on the air conditioning and fixed the problem. Price is reasonable and you can get a coupon on its website. Highly recommended!

Scott Maertin and his crew did an excellent job of installing a new furnace and air conditioner in our home. Their pricing was very competitive, they arrived on time along with being extremely thorough in their detailed explanation of how our new system works.
We couldn’t be happier with our Maertin Heating & Air Conditioning experience.
