Our History

Earl F. Christensen – Founder (Retired).

Earl started in heating and air conditioning in 1953. After working for two companies in 23 years, Earl started Earl's Heating & Air Conditioning in 1975. Soon after breaking ground with the new business at 4440 W. 61st Ave. in Hobart, Indiana, Earl brought on sons, Dave and Ken in 1976. Earl worked full time for 11 more years and then semi-retired in 1988 at the age of 65. In the fall of 2000, Earl completely retired and moved to Washington State to live with his daughter Karen. He happily lives in a log cabin with a perfect view of Mt. Rainer. Earl is 86 years old now and doing very well. For those of you who know him, he has had his knees replaced which has given him a new lease on life.

We became a Trane dealer in 2002.

In 2014 Earl’s Heating & Air Conditioning, Inc. moved to our present location at 5050 W. Lincoln Hwy Schererville , Indiana. We are half way between Highways 65 & 41 on Route 30 and very easy to find.

One of the great qualities about Earl (other than the fact that he was probably the best repairman in Northwest Indiana) is his honesty and integrity. This continues to be the most important quality for us.

Our Qualifications

We are a Trane Comfort Specialist Dealer.

We have been given the Trane Distinguished Dealer award for the Chicagoland and Northwest Indiana area 5 years running. Very few dealers achieve this honor and we take great pride in it.

We are heating and cooling professionals! We maintain a high level of quality among our staff. Our installers and technicians attend regular training classes certified by industry organizations:


This badge lets you know you’re working with a Trane dealer of the highest standing. A dealer who is committed to the best in every aspect of our business, from installation and service, to customer satisfaction and employee training.

Not every dealer qualifies as a Trane Comfort Specialist™ (TCS) dealer. Each year, we qualify for Trane Comfort Specialist™ status by meeting Trane’s stringent standards and demonstrating a commitment to customer satisfaction and continuing education.

TCS dealers across the country have earned a 90% or higher customer satisfaction score and a 85% or higher customer referral rate. Our score is 97% –– we strive for 100% satisfaction with every customer!


North American Technician Excellence (NATE) is an independent, third–party organization that develops and promotes excellence in the installation and service of heating, ventilation, air conditioning, and refrigeration equipment by recognizing high–quality industry technicians through voluntary testing and certification. Our technicians and installers attend NATE certified training courses.


National Comfort Institute is one of the country’s top training and certification organizations. NCI started in 1992 as National Balancing Institute, a training organization aimed at helping heating and air conditioning contractors provide even comfort throughout homes and businesses using a technique called Air Balancing. This technique, previously only available for large commercial and industrial facilities was refined to work in smaller buildings and homes.

As NCI evolved, the organization widened its scope to include a total system approach to design, installation and service of heating and air conditioning systems. We call this approach "Performance–Based Contracting." These contractors are different from the average service company because they do more than simply fix or replace equipment. They also focus on maximizing the comfort, safety and energy efficiency of the systems they sell and service.


The Better Business Bureau (BBB) system in the U.S. extends across the nation; coast–to–coast, and in Hawaii, Alaska, and Puerto Rico. Since the founding of the first BBB in 1912, the BBB system has proven that the majority of marketplace problems can be solved fairly through the use of voluntary self–regulation and consumer education.

We are a BBB Accredited Business with an A+ rating.

Energy Star Certification is a program of the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy to help us save money and protect the environment through energy efficient products and practices. In 1992 the EPA introduced the ENERGY STAR program as a voluntary labeling program designed to identify and promote energy–efficient products and reduce greenhouse gas emissions.



Through the United Way we have donated furnace equipment and installation for those in need in Northwest Indiana.

We support the local economy and promote jobs right here where we live and work by our involvement in the Chamber.
