A Homeowner’s Guide to Lennox HVAC Systems
Brand Profile: Carrier

Carrier’s journey began in 1902, when mechanical engineer Willis Carrier invented the first modern air-conditioning system to control humidity in a Brooklyn printing plant—marking the birth of modern HVAC. In 1915, Carrier Engineering Corporation was established and grew into a global HVAC leader. Now part of Carrier Global Corporation (spun off from UTC in 2020), it serves customers in over 160 countries with more than 48,000 employees.
