K & B HEATING AND COOLING SERVICE
Two Decades. One Standard. Zero Shortcuts.
K & B HEATING AND COOLING SERVICE was founded in 1998 by veteran HVAC technician Kevin Brennan, who started the business after managing multi-building climate systems for a major Chicago retail portfolio. With over two decades of experience in large-scale commercial HVAC operations, K & B specializes in providing centralized monitoring and maintenance for multi-property portfolios, ensuring consistent performance across all sites under one reliable service provider.
Why K & B HEATING AND COOLING SERVICE
Multi-Property Management Expertise
Kevin Brennan has spent nearly three decades—since 1998—focusing exclusively on large-scale HVAC systems in multi-family apartment buildings, which means he understands how complex heating and cooling failures affect entire portfolios. As a solo operator with deep hands-on experience managing multiple units at once, K & B HEATING AND COOLING SERVICE offers tailored solutions for landlords, property managers, and institutional clients who need consistent performance across dozens or even hundreds of systems.
24/7 Emergency Response You Can Count On
While our regular business hours are Monday through Friday from 7am to 5pm, we offer a separate, genuine 24/7 emergency line specifically for urgent no-heat/no-cool calls. This dedicated service ensures that critical failures in multi-unit buildings—like a broken furnace or AC unit in a high-rise—get immediate attention without waiting until the next business day.
Specialized Knowledge in Apartment Building Systems
Unlike general contractors who may not have deep experience with the specific challenges of multi-family HVAC systems, Kevin Brennan focuses solely on apartment building furnace and AC maintenance and repair. He knows how to handle issues like centralized boiler failures, individual unit thermostat malfunctions, and recurring condensate drain problems that plague residential complexes—delivering reliable fixes that keep tenants comfortable and reduce downtime.
