Lansing Heating & Air Conditioning

Lansing Heating & Air Conditioning Inc. has kept homes comfortable in St John and surrounding Northwest Indiana communities since 1971, earning a 4.9-star rating across 178 verified reviews. This BBB A+ rated, licensed contractor operates as a Carrier Factory Authorized Dealer, a distinction fewer than five percent of heating and cooling professionals nationwide achieve. Serving the greater Chicagoland corridor and Northwest Indiana, including Schererville, St John, and nearby Lake County neighborhoods, the company handles both residential and light commercial projects with a staff of NATE-certified technicians.

What distinguishes Lansing Heating is their ability to service virtually any make or model while maintaining manufacturer-authorized status, giving customers access to warranty protections and rebates unavailable through independent shops. Their comprehensive service menu spans new equipment installations, seasonal maintenance agreements, air quality improvements includingduct cleaning and WiFi thermostat integration, and specialized work such as sheet metal fabrication for custom duct runs. The company offers financing options and maintains a straightforward approach: transparent assessments, named technician assignments, and commitment to completing every job to manufacturer specifications.

Customer stories reveal consistent patterns: Todd diagnosing complex issues in newly purchased homes and recommending reasonable solutions, Rich performing thorough cleanings and maintenance for two decades on the same systems, and Rob and Ben handling furnace and air conditioner replacements with product knowledge and patience. Multiple reviewers highlight multi-decade relationships spanning 20 to 30 years with the same technicians, noting on-time arrivals, flexible scheduling, and upfront honesty about what repairs are necessary versus optional upgrades.
