The company holds appropriate licensure for northern Illinois and maintains same-day response capabilities for urgent heating and cooling emergencies.

As a Lennox factory-authorized dealer, Assured Appliance & Heating & Air installs and services the complete Lennox residential product line, including furnaces, heat pumps, mini-split systems, air handlers, and the Healthy Climate indoor air quality suite. The company offers financing options through third-party lenders and provides upfront pricing before work begins, helping homeowners budget for unexpected replacements without surprise charges. Their expertise extends to complex installations involving thermodynamic upgrades, foundation-wall venting, and custom ductwork modifications that require engineering solutions beyond standard replacements.

Customer reviews consistently credit Jason Harjump by name for exceptional responsiveness during heating emergencies. When one family's 50-year-old furnace failed on a frigid MLK holiday weekend with temperatures at 7 F, Jason arrived within two hours, assessed the unsafe condition, and loaned space heaters to prevent pipe freezing while sourcing an appropriately sized replacement. He coordinated a Monday installation with additional technicians, completing thermostat wiring, PVC exhaust routing, and ductwork transitions in a single day. Another reviewer describes a 5:00 AM call resulting in a new furnace installed by noon, praising the team's professionalism and fair pricing.
