Cornelius Contracting Heating and Cooling LLC

Cornelius Contracting Heating and Cooling LLC operates as a multi-trade contractor serving St Joseph, Missouri and surrounding communities including Country Club, Gladstone, Kansas City, Leavenworth, Liberty, Parkville, Overland Park, and Platte City. The business maintains a 4.7 rating derived from 74 customer reviews, with technicians available around the clock seven days a week. Beyond heating and cooling services, the company handles electrical work, plumbing, and property management projects ranging from residential repairs to larger-scale installations across duplexes and apartment complexes.

What distinguishes this contractor is the in-house capability for custom metal fabrication, a trade-adjacent specialty that few regional HVAC companies offer. The business provides maintenance plans for both heaters and air conditioning systems, along with new system installations. Military personnel and senior citizens receive discount pricing, providing a tangible savings opportunity for qualifying homeowners.

Customer reviews consistently highlight technician Preston, who responded same-day during a Fourth of July emergency, arrived within two hours for an AC recharge request Saturday morning despite a full schedule, and solved an AC problem within hours during a sudden rainstorm for a reviewer located 45 minutes from St Joseph. Another reviewer described Preston handling an after-hours emergency alongside team member Jared, completing the repair as promised. Sunday water heater failures and subzero weather scenarios also brought prompt responses, with one reviewer noting fair pricing and fast work.
