Illiana Heating & Air Conditioning, Inc.

Illiana Heating & Air Conditioning, Inc. has operated from Cedar Lake since 1987, building a client base across Northwest Indiana that includes neighboring communities like Crown Point, Griffith, and Dyer. The company holds proper state licensing for residential HVAC and plumbing work, and maintains an A+ rating with the Better Business Bureau. With 2,266 customer reviews averaging 4.9 stars, Illiana employs technicians who can respond to service calls seven days a week, from 8 AM well into the evening. This longevity reflects stability that homeowners in volatile Indiana weather can depend on for their heating and cooling needs.

What distinguishes Illiana from neighboring contractors is their multi-trade capability and product breadth. As an authorized dealer for Lennox, American Standard, and Bryant equipment, the company installs and services geothermal heat pump systems, a niche offering that requires specialized training uncommon among generalists. Their website also advertises zone control systems, allowing homeowners to regulate temperatures room-by-room, and REME HALO air purifiers that address indoor pollutants. Notably, Illiana added plumbing services, handling water heaters, pipe repairs, and drain cleaning, reducing the number of contractors a homeowner must manage.

Customer reviews name specific technicians who handled distinct situations. Victor Quinones transitioned from radiant heat to forced-air heating; his technician Kevin walked him through filter changes and explained what to expect from the new system. Nestor Paul Romero noted his technician arrived with clear purpose: getting the furnace operating efficiently, and found the pricing unusually fair compared to other companies. In contrast, Benjamin Stonewall acknowledged technician Jerry arrived promptly and solved the problem but felt the part markup exceeded expectations. These detailed accounts reveal how transparency in pricing matters as much as technical skill.
