KO HEATING AND COOLING

KO Heating and Cooling serves the Lombard, Illinois community with a perfect 5-star rating across 17 verified reviews, establishing themselves as a trusted residential and light commercial HVAC service provider. The company operates Monday through Friday from 8 AM to 4 PM, providing scheduled maintenance, repairs, and system installations throughout Lombard and surrounding DuPage County communities. All eight customer reviews reference either emergency same-day service or rapid turnaround times, indicating the company prioritizes responsive client care.

Without a company website, specific brand partnerships or specialized certifications cannot be confirmed from authoritative sources. The reviews consistently reference fair and reasonable pricing, with multiple customers specifically noting affordability alongside professional craftsmanship. This value-oriented approach appears to distinguish KO Heating and Cooling from competitors, though prospective clients should confirm specific service offerings and equipment brands during initial consultation.

Several reviewers describe specific scenarios that demonstrate the company's service speed and problem-solving capability. One customer recounts a heating system failure on an extremely cold day, where KO Heating and Cooling diagnosed the issue, sourced a replacement motor, and completed installation within approximately two hours. Another reviewer describes a thermostat failure that persisted after treatment by another contractor, which KO Heating and Cooling resolved in just 30 minutes. The technician named Freddie appears across multiple reviews for both emergency AC repairs and heating system diagnostics, with customers consistently describing him as reliable, professional, and skilled at identifying issues quickly.
