Our story

Family owned
since 2007.

Founded by the Kowalski family, Northshore HVAC has been keeping Chicagoland homes comfortable for over 15 years. What started as a one-truck operation has grown into a trusted team serving the north suburbs.

Why we started

We wanted a heating and cooling company that treated every house like our own — where techs arrive in marked vans, wear floor protectors, and leave systems cleaner than they found them. Today that philosophy still drives hiring, training, and pricing.

Certified expertise

Every lead technician carries NATE credentials, EPA 608 refrigerant certification, and ongoing factory training from the brands we install most. We document photos, pressures, and temperatures so you always know what we changed and why.

Service area

We serve homeowners throughout Chicagoland suburbs, from Lake County collar communities through the western and southern corridors. Call with your ZIP code and we will confirm dispatch availability the same day whenever possible.
