What's on the truck when it leaves for Lake City
Four groups of work, one dispatch, every kind of Columbia County building. The tiles below link to each service; this is how they fit the town.

Cooling, for Mays that act like July
Lake City’s air conditioners run hard from May through September, through 90-degree afternoons and a thunderstorm most days. Repair, maintenance and installation of cooling equipment is the largest share of the work here, from capacitors cooked in Callaway garages to full Lennox replacements for the late-1990s systems in Summers Ridge.
Heating, because the 20s show up most winters
Many Florida contractors treat heat as a formality. In Columbia County that’s a mistake: the first freeze lands by mid-December in a typical year and hard freezes into the 20s happen often enough to matter. Heat pump repair, maintenance and installation are a real line of work here, along with furnace service for homes on the city’s natural gas system and the propane-fed houses outside it.
Air that fights pollen, damp and well-water dust
Spring pollen that turns filters yellow in a fortnight, a September dew point that keeps a block ranch sticky at 76, and the fine mineral residue hard water leaves behind: the indoor air group covers filtration, dehumidification, duct sealing and duct cleaning for all of it.
Commercial at the crossroads
The I-75/I-10 interchange, the clinics around the VA Medical Center and Lake City Medical Center, the warehouses north of town and the storefronts on US 90 all need rooftop and split-system work on a schedule that doesn’t close the business. Cook’s does commercial repair, maintenance and installation on the same dispatch as residential.
How the drive fits in
Every service above arrives from Palm Coast, 121 miles away, usually on a planned Columbia County route day. Emergency work goes out any hour without an after-hours charge. Pick a tile below for how each service runs in Lake City specifically.
Service questions from Lake City
Can one visit cover both the air conditioner and the gas furnace in our downtown house?
Yes. A technician handles the cooling side and the heating side in the same appointment, including gas furnaces on the Lake City Utilities system.
Do you handle the duct work under a manufactured home, or just the equipment?
Both. Belly-board duct is where most of the lost air goes in a Columbia County manufactured home, and a new heat pump bolted to leaking duct is a waste. Sealing, insulating or replacing those runs is part of the service line.
Is geothermal realistic on karst ground in Columbia County?
It can be, with a proper site evaluation. The aquifer is close and the ground is porous, which is both an advantage and a risk; loop design and well-water chemistry decide it.
