Popa Heating & Cooling, Your Trusted Local Northwest Indiana HVAC Company

Popa Heating & Cooling has been serving the heating and air conditioning needs of Northwest Indiana communities since 1968. Originally founded by Nick Popa in 1968, he previously ran the sheet metal shop for Carl Pettit Builders, known for building many of Highland, Indiana’s homes during the 1950’s and 1960’s. Nick decided it was time for a change and he ventured out on his own and started Popa Sheet Metal. His focus on servicing his local community established our reputation as a reliable company that is focused on the needs of the customer.

Pat Popa joined the company in 1986. In 2010 she became CEO and rebranded Popa Sheet Metal to Popa Heating & Cooling. The initial focus was on installing heating and cooling systems into new home construction, but growth and success have enabled us to expand our services into existing residential heating and cooling in the Northwest Indiana area. We offer new installations for existing homes, and provide system services, repairs and equipment.

December of 2022 brought an exciting time to Popa Heating & Cooling! As Pat moved into retirement with Nick, Jesse Hernandez, her long time field supervisor, purchased the company December 1, 2022. Jesse Hernandez was born and raised in Northwest Indiana, and has been in the Heating and Cooling field for over 20 years, working at local companies. Pat had often referred to Jesse as her right hand, so it was only natural that the business live on with his ownership.

We specialize in Trane products, but Popa Heating & Cooling also services all other makes and models of HVAC equipment, including gas forced air, ductless mini-splits, and hot water boiler systems.

While residential HVAC is our main focus, we also do various light commercial work including rooftop units. Contact us today for your next job!

Popa Heating & Cooling in the Community

At Popa Heating & Cooling, we are proud to provide the area with top-quality HVAC services, but we truly enjoy being able to give back to the Highland community. Over the years, our company has been a part of organizing projects in downtown Highland and across the Region that have helped increase traffic for the retail business district and improve the quality of life for residents.


Helping Humane Indiana

Humane Indiana is an organization that is close to our hearts. A portion of all of our sales is donated to help maintain the Humane Indiana HVAC equipment. Popa Heating & Cooling helps them by performing routine, seasonal HVAC cleaning, checks, and maintenance, like changing out filters to help keep them up and running.

Former owner Pat Popa also helped raise money for the Humane Indiana Wildlife Center through the Owl You Need is Love project in 2019. Inspired by the owls that reside at the rescue, local artists painted fiberglass owls in fun and unique ways that were purchased by sponsors or auctioned off. These painted owls lived in various locations around the Highland community, delighting local residents and visitors. To read more about the Owl You Need is Love project, click here.

Donating to the American Legion

The entire Popa Heating & Cooling team proudly support our American Veterans, and in Fall of 2022, we had the chance to show our support by donating and installing a new Trane heating and cooling system at the American Legion Allied Post 369 in St. John, IN.

Our team worked closely with Post leaders Commander Frank Darrington and past Post Commander John Sarnecki to make arrangements to get the work done, ensuring our local veterans have a safe and comfortable space to connect and support each other while educating and working in the community.

Learn About Financing

"When I first set out to find a contractor that would entertain the possibility of a heat pump to replace an aging upstairs closet gas furnace, these guys stood out for a few reasons. They weren’t scared of the work. They had the right attitude and enthusiasm for the job and I can tell they enjoy what they do and getting it right. They were able to brainstorm and come up with solutions for a challenging installation in an old house. The end result was a brand new 1.5 ton Mitsubishi ducted heat pump. They cleaned up the closet nicely, creating a custom stand for the air handler and improved the installation by cutting in an additional return grille.

No more hearing the burners kick on and the loud single speed blower. It’s such an improvement over what we had and impressive to see how far heat pumps have come in the last decade or so. The system is in constant communication with the outdoor inverter compressor to operate efficiently and unbelievably quiet.

Thanks Matt and Jesse and all the others who made it happen.”
