About Our History
Cosgriff Climate Control came under new management in 2014 when Mark and Alicia Cosgriff purchased the business. Since then, they’ve provided customers in Hermantown, Proctor, Duluth, Superior and beyond with fair and efficient heating and cooling services. Our staff is not only good at what they do, but will always treat you with respect and be honest about their work. We work tirelessly to establish a trustworthy relationship in order to become your go-to business for all of your HVAC needs.
Our new gas furnace and central air conditioning system was installed in November of 2014, and has performed flawlessly ever since. The team who made it all happen was friendly and well-mannered. I thought the price was fair and I took advantage of several rebates and the federal tax credit for new heating equipment. The job went smoothly and I couldn’t be more pleased with Cosgriff Climate Control.”
They are very good people that showed a little extra care when they were at my place working.”
I was very happy with the quality of work they did and how above and beyond they went. They are very nice people. I will definitely hire them again!”
If you are looking for a knowledgeable, honest and efficient company to address your heating and cooling needs, Cosgriff Climate Control is the one I would recommend.”
