Trusted HVAC Company in Champaign, IL

Reliable HVAC in Champaign, IL

For dependable HVAC in Champaign, IL, homeowners and business owners turn to Sussen Heating & Cooling. Whether it's a furnace that won't start on the coldest morning of the year or an air conditioner that's given out in July, our licensed technicians respond quickly and get the job done right the first time.



Owned and operated by Jamie Sussen, a veteran with over 15 years of HVAC experience, we bring honesty, fair pricing, and dependable workmanship to every job in Champaign and the surrounding area — from a brand-new system install to a routine tune-up.

Built for Champaign's Climate and Its Housing Stock

Champaign sees some of the widest temperature swings in the state — bitter cold snaps in January, humid highs in July — which puts real strain on HVAC systems that aren't sized or maintained correctly. Add in a mix of century-old homes near downtown and newer construction closer to the University of Illinois campus, and no two Champaign systems are quite alike. We size and service equipment for the specific home in front of us, not a one-size-fits-all install.
