AB Heating and Cooling

AB Heating and Cooling has kept Chicago families warm and comfortable since 1965, making it one of the longest-running family-owned HVAC contractors in the city. The father-son team brings over six decades of combined experienceto every service call, covering not just Chicago proper but the entire Chicagoland area from the Loop to the suburbs. With 122 customer reviews earning a 4.9-star average and around-the-clock availability every day of the week, AB delivers both the longevity local homeowners trust and the responsiveness that emergencies demand.

What distinguishes AB Heating and Cooling is a commitment to cost-effective solutions that other contractors in the area do not share. Unlike companies that push costly full-system replacements at the first sign of trouble, this team recommends the most affordable fix that will restore your system to reliable operation. Their indoor air quality division stands apart as well, offering whole house air purification, advanced filtration systems, and whole house humidifiers that work with existing equipment to improve health and comfort year-round. Commercial clients benefit from their specialized rooftop unit expertise and preventive maintenance programs designed to minimize costly downtime.

The reviews tell the real story: Andy, the service manager, replaced one customer's furnace after a thorough assessment that explained exactly why the new system would be efficient and effective for their specific home. Another reviewer called Andy out before winter arrived, and the technician arrived on time, explained every step of the process, and left the workspace cleaner than it was before. These are the details that repeat across reviews, technicians who show up when promised, explain what they are doing, and recommend honest solutions without pressure.
