Our Story
HVAC Contractor with Jacksonville Roots Serving Florida Statewide
Robert Kline runs Oakleaf Heating & Air LLC as an owner-operated business from its Jacksonville base at 4623 Lambing Rd. The company grew from deep local roots to handle HVAC work across the state, where humid subtropical conditions with hot summers and mild winters place steady demands on systems in homes of varying ages and construction.
Service runs Monday through Friday from 8am to 6pm and Saturday from 9am to 2pm, with an emphasis on clear upfront quotes and results customers can check on site before moving forward. This same practical approach applies whether the job sits in Duval County or reaches other parts of Florida.
The focus stays on matching equipment and repairs to actual site conditions rather than one-size solutions, keeping performance steady through seasonal swings and different housing types encountered statewide.
I started Oakleaf Heating & Air LLC after years handling HVAC work in Duval County homes, from the older stock in Riverside and Avondale to newer builds in Mandarin and Arlington. The humid subtropical conditions here, with hot summers that push systems hard and mild winters that still require attention, taught me exactly what fails and why. We keep regular hours at our Lambing Road location so customers across Florida can reach a local crew that knows how coastal humidity and river proximity change the job on the ground.

What Florida Customers Say
“My upstairs unit quit cooling right when temperatures hit the nineties in July. The technician found a failed run capacitor and dirty evaporator coils, replaced the part, cleaned the coils on site, and recharged the system. The house now holds 72 degrees steadily with no short cycling.”
“Duct leaks in the attic were pushing my electric bill over three hundred dollars. Oakleaf Heating & Air LLC sealed the joints with mastic, added insulation around the main trunk lines, and tested airflow. The next bill dropped by almost eighty dollars.”
“The old thermostat in my 1960s home kept drifting five degrees off and the heat pump ran constantly. They replaced it with a new programmable model, verified the reversing valve operation, and balanced the airflow. The system now cycles normally and keeps humidity under control.”
