About Efficient Heating & Cooling

Justin Synowiec has spent close to 15 years in the HVAC industry, from working on residential to commercial projects. He started Efficient Heating & Cooling because while working with some fantastic organizations, he saw an opportunity to improve the process and customer experience for the consumers. 

As a truly family-run local business, Justin and his brother Chris started Efficient Heating & Cooling to serve McHenry, Lake and Cook Counties in Illinois for both residential and commercial HVAC needs. They then brought on a service manager (Matt) to help expedite the process and improve the quality of service for homeowners in the area. With our expertise, we can take care of all your HVAC needs.
