Hartley's Climate Control

Hartley's Climate Control maintains a near-perfect 4.9-star rating across 318 verified customer reviews, placing it among the most recommended contractors serving Rolla and St. James, Missouri. This family-operated business has expanded from its original St. James location to open a second depot in Rolla, currently operating as the largest heating, cooling, and plumbing company within a 30-mile radius. The company provides around-the-clock emergency availability on all seven days, including holidays , ensuring homeowners never face a heating system failure or cooling breakdown without rapid response capability.

What distinguishes Hartley from regional competitors is the breadth of expertise spanning multiple building trades. Their licensed technicians handle geothermal and hydronic heating systems, commercial kitchen refrigeration, custom sheet-metal fabrication, and indoor air quality solutions including REME HALO UV purification, high-efficiency humidifiers, and whole-house filtration. The company partners with virtually every major heating and cooling equipment manufacturer, enabling them to recommend and install replacement systems tailored to specific home layouts and utility budgets rather than pushing a single brand inventory.
