KLM

KLM Heating & Cooling has kept Louisville comfortable since 1997 as a family-owned, A+ rated BBB business. This contractor holds Kentucky license #KY1742 and serves residential and commercial clients across Louisville, Hurstbourne, Jeffersontown, Fern Creek, Lyndon, Middletown, Mount Washington, and St. Matthews. With a near-perfect 4.9-star average from 577 reviews, their team of Nate-certified technicians handles furnace repairs, heat pump installations, boiler services, and preventative maintenance. The office at 11216 Decimal Drive operates Monday through Friday from 7:30 AM to 5 PM, with 24/7 emergency service available for sudden HVAC failures.

What distinguishes KLM is their commitment to individualized solutions over cookie-cutter replacements. Every new installation is uniquely designed to match the specific needs of each home or business, and the company backs all work with a 100% satisfaction guarantee. They offer financing options for qualified buyers and maintain certifications in commercial HVAC, refrigeration, and restaurant equipment repair, a niche specialization not common among residential-focused contractors. As a Christian-based company, their service philosophy emphasizes honest diagnostics and transparent pricing rather than recommending unnecessary replacements.

Rich and Carol Ann's recent review highlights how technicians Sean, Nick, and Bradley completed a challenging new system installation during rain, taking care to protect flooring with drop cloths while answering every question. Angie White described receiving a same-day estimate followed by installation just two days later, Jermane and Dan managed the seamless replacement of a failed heat exchanger. Another reviewer, Megan, appreciated that the service technician correctly identified an old filter issue rather than overselling repairs, saving her from an unnecessary expense.
