About JNL Climate Control

JNL Climate Control proudly serves the HVAC needs of the Northern Illinois suburbs including East Dundee, Arlington Heights, Crystal Lake, Algonquin, Barrington, Hoffman Estates, Schaumburg & surrounding areas.

John and Lauren Beening founded JNL Climate Control, Inc. in 1991 in Hoffman Estates, Illinois.  Their mission was to provide the highest quality service to commercial and residential customers who need new heating or cooling equipment or maintenance and repair of existing systems.  As they have grown, their commitment to quality performance and customer satisfaction has kept JNL Climate Control a thriving HVAC company.  We currently provide HVAC services to customers in Palatine, Elgin, Bartlett, Cary, Hoffman Estates, Lake in the Hills, Schaumburg, and the entire Northwestern suburbs of Chicago.

In 1998 John partnered with Kurt Olszewski. The partnership allowed the company to expand further into communities in Northern Illinois.  With memberships in the Hoffman Estates and Northern Kane County Chamber of Commerce, as well as the Professional Service Contractor group, our principles are centered around providing quality furnace repair, air conditioning repair and other HVAC services to the communities we serve.

John and Kurt share this philosophy:

Customer service is of paramount importance. The customer is #1 and customer satisfaction is 100% guaranteed.
