Family-Owned Service Since 2019
Meet the Owner
Jonathan Roswall
Owner & Founder
Jon Roswall has spent most of his life in the trades and comes from a multi-generational family of HVAC professionals. With over 30 years of industry experience, he has worked on everything from residential service and system replacements to complex commercial HVAC projects throughout the country.
In 2019, Jon and his wife, Miranda, founded Olympic Air with a simple goal: to provide honest recommendations, quality workmanship, and dependable service that homeowners and businesses can trust.
While the HVAC industry has changed significantly over the years, Jon remains committed to treating customers the way he would want his own family treated — with respect, transparency, and professionalism.
Known for his attention to detail and problem-solving ability, Jon believes proper system design, installation quality, airflow, and humidity control are just as important as the equipment itself. His passion for the trade and commitment to customer satisfaction continue to guide Olympic Air today.
When he is not serving customers, Jon enjoys spending time with his family and supporting the local community that Olympic Air proudly calls home.
"Our goal isn't to be the biggest company. It's to be the company our customers trust and recommend to their family and friends." — Jon Roswall"
