McCormack Heating & Cooling Inc.

McCormack Heating & Cooling Inc. has served Olathe and the surrounding Johnson County communities since 1985, building a reputation on honest work and reliable service. The company holds proper licensing for residential HVAC work in Kansas, and maintains an exceptional 5.0-star rating across 19 verified customer reviews. Owner-operated by John and Scott, the team focuses on service rather than aggressive sales tactics, supporting homeowners throughout multiple homes and system lifecycles.

What distinguishes McCormack is their long-term approach to customer relationships, with reviewers noting 13 to 20 years of continued service across households. The company handles equipment from major manufacturers including Armstrong Air, and provides straightforward replacements for worn components like humidifiers and flue systems. Their Saturday morning availability and willingness to evaluate concerns quickly set them apart from contractors with limited hours.

Customers consistently praise Jon for responding to furnace concerns within hours of calling, arriving to assess issues and explain findings clearly. Scott earned recognition for treating a home as if it were his own during a humidifier and flue replacement project, taking care of every detail. John and Scott both receive mention as the definition of professionals, technicians who go out of their way on multiple occasions and have built a 20-year reputation serving neighbors in the community.
