KNZ Heating and Cooling

KNZ Heating and Cooling operates in Lowell, Indiana with a 4.3-star average rating compiled from 90 client reviews. The company maintains standard weekday hours from 9 AM to 5 PM, serving residential customers throughout the greater Lowell area and neighboring communities. Reviewers indicate the company has served clients in St John and other nearby Lake County locations, providing both heating and cooling system maintenance.

The company distinguishes itself through proactive customer care practices that reviewers consistently mention. Multiple clients note receiving filter change reminders, a service approach that helps prevent system failures before they occur. This preventive maintenance philosophy appears throughout customer feedback, with technicians taking time to explain system operation and answer questions about equipment maintenance.

Customer experiences highlight specific technician encounters that demonstrate the company's service approach. When a reviewer with a 30-year-old Weil-Mclain boiler experienced a breakdown, Nick arrived within hours and diagnosed a failed fluid level module, completing repairs the following day. Another reviewer describes Keith and his team providing installation services while keeping a homeowner informed throughout the process. These scenarios reflect the communication-focused service model that reviewers praise.
