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


Established in 1968 by Nick Popa, we've proudly served Northwest Indiana communities for over five decades. Nick, previously with Carl Pettit Builders, initiated Popa Sheet Metal, emphasizing community service and reliability.


In 1986, Pat Popa joined and later became CEO in 2010, rebranding us to Popa Heating & Cooling. Initially focusing on new construction installations, we've grown to serve existing residential HVAC needs in Northwest Indiana.


Exciting changes occurred in December 2022 as Jesse Hernandez, a seasoned field supervisor and local expert with over 20 years of experience, took over ownership from retiring Pat and Nick. Specializing in Trane products, we service various HVAC models, including gas-forced air, mini-splits, and hot water boilers.


While residential HVAC remains our core, we also handle light commercial projects, including rooftop units. Get in touch for your next HVAC job!

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 supports our American Veterans, and in the 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.
