Interlachen's lakes do not cool the house. They do the opposite.

The belief, and what is actually true

“We’re right on the lake, we get a breeze, we barely need the AC.” We hear it in Interlachen every summer, usually from an owner whose cottage smells musty and whose bathroom door has swollen shut. The breeze does cool skin. It does nothing for the air conditioner, and the moisture it carries off twenty-eight lakes into a house with open porches and single-pane windows makes the system work harder than the same house would on dry ground.

The correct version is: a lake house in Interlachen needs the same cooling capacity as any other and more attention to humidity than most. Oversizing it because it “gets hot by the water” makes the moisture problem worse; undersizing it because of the breeze leaves it running all day. Sizing it correctly, and setting it up to dehumidify, is the whole trick.

The town between the lakes

Interlachen is a town of about fourteen hundred on SR 20, seventeen miles west of Palatka, and the name means what it says. More than two dozen lakes lie within and around the town limits on the sandy ridge that runs through western Putnam County. The housing is lake cottages from the 1950s through the 1970s, a large share of manufactured homes on sandy lots away from the water, block ranches from the same decades, and newer houses scattered among them. Nearly every address is on a private well and on Clay Electric.

Hollister is the crossroads on SR 20 between Palatka and Interlachen, a small unincorporated community of manufactured and frame homes on larger tracts, also on wells and Clay Electric, which we pass through on every Interlachen call.

The ground moves

The ridge that holds the lakes is deep sand over limestone, and it is sinkhole-prone country; Lake Barco and Lake Suggs are lakes because of it. For air conditioning the day-to-day effect is smaller but constant: outdoor pads settle and tilt, line sets get strained, condensate drains that terminated at grade end up buried, and manufactured-home piers shift enough to pull duct joints apart underneath. We check pad level and line-set strain on every visit here, which is not something we do in most of the county.

Lake cottages

The cottages on the water are small, built for weekends, and often cooled by a window unit in each room or a single through-wall unit. They are left closed up between visits with the air conditioning off, which in a Florida summer is how mold takes a house. The fix we recommend most is a ductless system with a head in each main room and a humidity-sensing thermostat that keeps the air dry while nobody is there. It costs less to run than a row of window units and protects everything inside the house.

Manufactured homes on the sand

Away from the lakes the housing is largely manufactured, running package units with duct under the floor. Sand under the home drains fast, which keeps the crawlspace drier than along the river, but the pier settling described above pulls duct seams open and the undersized returns these homes come with limit airflow. Duct inspection is part of every maintenance visit.

Clay Electric territory

Interlachen and Hollister sit in Clay Electric Cooperative’s service area, which matters in two ways. Rural co-op lines take lightning and switching surges that fry control boards, so surge protection is worth having. And Clay’s Energy Smart program publishes rebates for qualifying high-efficiency replacement heat pumps and mini-splits, with an application window after installation. We help with the paperwork and will confirm the current program details before you count on a number. [[CONFIRM WITH JERRY]]

From Palm Coast to the lakes

Cook’s is based at 37 Fairmont Ln in Palm Coast. The route runs SR 100 to Palatka, then SR 20 west through Hollister to Interlachen, about an hour and ten minutes. We carry parts for every brand on the truck, we are a Lennox dealer for new systems, and the phone is answered every hour without an after-hours charge.
