Professional Affiliations
At Cliff’s we have always believed that we cannot provide quality service without employing quality people.
Our employees are certified by N.A.T.E. (North American Technician Excellence) as Air Conditioning – ACE Service Technicians. Additionally, our technicians attend and complete numerous factory-sponsored training seminars.
As a York CCE Dealer, Cliff’s is able to provide superior service with the backing of one of the best names in the heating & air conditioning industry.
Recognizing that we are a small business, our membership with N.F.I.B. enables us to voice our opinion on matters that directly affect everyday consumers of our goods and services.
The community is our marketplace; therefore, our membership in the Schererville Chamber of Commerce is a must. Cliff’s has been a member in good standing since we built our facility in Schererville.
History
Cliff’s was founded in 1979 by Clifford Purnell, Sr., as a small service shop that served both the residential and light commercial heating, air conditioning, and refrigeration markets. Over the years, Cliff’s has grown to serve customers in over 42 cities across the Illinois and Northwest Indiana markets.
In 2000, Cliff Sr. welcomed his son, Cliff Jr., into the operation, as a move to guarantee the tradition of superior service established years earlier. Cliff Jr. brought both new energy and fresh ideas into the company.
In 2002, Cliff’s constructed a new office/warehouse facility at our current location in Schererville. This expansion allowed us to consolidate our HVAC and back-up power generation products under one roof. Additionally, it will allow us to transition into a Premier Home Comfort Services Provider.
Residential HVAC servicing and replacement still comprises over 90% of our business. Our craftsmen are trained and certified by N.A.T.E. and our major suppliers.
We know that we are large enough to provide prompt and efficient service, yet small enough to care about each individual customer. As the leader in residential service, we will not stand for anything less. A wise man once said, “Becoming Number One is easy, maintaining excellence is Leadership.”

Yesterday, we had Hunter, Edward, and Robert install a home Generac generator. This team was so professional. They were super clean and respectful of the property. Hunter was the original contact who sold us the equipmet. We are impressed that he also worked on the installation. The employees really do care about getting the job done right. They answered all our questions and were genuinely concerned about customer service and our satisfaction. For these reasons, I highly recommend that you purchase your generator from Cliff's and I am adding a 6th star too this review too!
