Our commitment to excellence

We would like to take this opportunity to introduce our company to you. Martens Heating and Mechanical has been in business in the Fox Valley area since 1976. Fully licensed and insured, Martens Heating and Mechanical is committed to providing value and service to our many residential and commercial customers. This is a mission we do not take lightly. To us, value means giving our customers the best possible system their money can buy. To achieve this end, we are proud to offer a wide selection of product lines. By working closely with our customers to determine their priorities, we can then select products to custom design a system that will deliver the performance and features they are looking for in home comfort. This unique approach takes advantage of the best features and innovations from each manufacturer, rather than using a package system from a single manufacturer.
