At KLM Heating & Cooling, our purpose is simple: keep homes and businesses across Louisville and the broader Kentuckiana community comfortable in every season. Rooted in Christian-based values and guided by the vision of owners Randy Kearney and Tony Logsdon, our team blends time-tested craftsmanship with attentive service. From the first phone call to the final system check, we design the experience to be clear, courteous, and efficient so restoring your comfort is completely hassle-free.

Known as a leading name for furnace repair that Louisville residents trust, we respond quickly when the chill sets in and your heat will not kick on. Our technicians arrive prepared to diagnose issues efficiently, explain your options plainly, and complete repairs with care—whether resolving a faulty ignitor, replacing a worn blower motor, or calibrating a finicky thermostat. When age or repeated breakdowns make ongoing repairs impractical, we guide you through full-system replacements, matching high-performance equipment to your specific space and budget for dependable, even warmth.

Summer brings a different set of challenges, and our cooling services are built to meet them. We cover precise AC troubleshooting, refrigerant and airflow corrections, thorough coil cleanings, and smart thermostat integrations that help tame rising energy costs. When a unit nears the end of its service life, we walk you through replacement choices—including central air systems, modern heat pumps, and high-efficiency options—always prioritizing long-term reliability and everyday comfort.

Proactive maintenance is where small efforts pay off the most. Seasonal tune-ups catch minor issues early, protect manufacturer warranties, and help your systems run quieter and more efficiently. Our comprehensive checkups include safety inspections, filter guidance, airflow balancing, and performance metrics you can easily understand. To further enhance your indoor environment, we offer air quality solutions—including advanced filtration, humidity management, and ventilation improvements—that foster a healthier home.

Commercial clients also rely on KLM Heating & Cooling for light commercial HVAC services that keep daily operations running smoothly. From rooftop unit service and zoning strategies to routine maintenance plans that reduce costly downtime, we build work schedules around your business needs and communicate proactively to ensure there are no surprises.

What sets our team apart is a service mindset shaped by integrity, character, and respect. Our technicians protect your floors, tidy up their workspace, and keep you informed every step of the way. Estimates are straightforward, and our recommendations reflect what we would do in our own homes and buildings. When timing is critical, we are available day or night because extreme temperatures will not wait.

We are proud to serve neighborhoods throughout Louisville and the surrounding Kentuckiana region. Whether working on a historic home that requires delicate ductwork attention, a newer build ready for a high-efficiency upgrade, or a local business that cannot afford a midweek shutdown, we tailor solutions to match the way you live and work. KLM Heating & Cooling was founded on a straightforward promise: do what is right, do it well, and stand behind the work. When comfort matters, count on a local partner who shows up prepared, solves problems thoroughly, and leaves you feeling completely confident.
