Hot Cold Air Heating, Air Conditioning & Air Duct Cleaning

Hot Cold Air Heating, Air Conditioning & Air Duct Cleaning has earned a 4.7-star average across 241 verified customer reviews while serving Northbrook and surrounding Illinois communities including Glenview, Wilmette, and Winnetka. The company maintains round-the-clock availability, meaning homeowners can reach them any hour for heating emergencies, air conditioning failures, or scheduled maintenance. Their service menu spans residential furnace and boiler work alongside commercial rooftop unit installation and repair, with a dedicated focus on indoor air quality improvements including whole-home air duct cleaning, UV light purification systems, and climate zoning solutions.

What distinguishes Hot Cold Air from neighboring HVAC companies is their multi-trade approach to indoor air quality , they don't simply filter air, they actively treat it using UV light induction systems designed to neutralize pathogens and allergens circulating through ductwork. The company also offers commercial refrigeration service, a specialty that many residential-focused contractors in the Chicago suburbs cannot match. Their financing options and membership agreements provide ongoing maintenance access, while the website references equipment registration programs that help homeowners validate warranty coverage for new installations.

Customer stories from recent reviews illustrate the company's problem-solving approach. Carol Magnano described calling at 8 a.m. during subzero weather when her home dropped to 62 degrees, and a technician arrived by 12:30 p.m. and completed repairs within 30 minutes. Another reviewer, Jim Johnson, noted his 10-year-old furnace looked practically new after maintenance and that the company performs annual service on both his heating and cooling systems. However, one customer reported dissatisfaction with a leak diagnosis and resolution, illustrating that results can vary depending on system condition and repair complexity.
