Where these came from

Every market Cook’s serves asks a different set of questions. In Lake City they’re shaped by Helene and Idalia, by the Floridan aquifer under half the county’s kitchens, by a downtown built before ductwork, and by the fact that four in ten homes inside the city are rentals. They’re also shaped by the honest distance from our headquarters at 37 Fairmont Ln in Palm Coast, which comes up on nearly every first call.

The questions below are the ones that don’t have a national answer. They came from driveways in Callaway and Mayfair, from a landlord with units near the college, from a pilot at the airpark and from more than one person standing over a condenser flattened by a pine limb. If yours isn’t here, the problem pages and guides under Resources go deeper, and the phone is answered at any hour.

Asked in Lake City

Does homeowner's insurance cover a lightning-fried control board, and will you help prove it was lightning?

Most policies cover lightning as a named peril, but adjusters want evidence. Our technician photographs the scorched board and any blown fuses, notes the failure pattern, and writes up the cause on the invoice in plain terms. Lightning hits Columbia County almost daily in summer, so this is routine paperwork for us.

After Helene, our adjuster asked for an HVAC cause-of-loss letter. Can you write one?

Yes. We inspect the equipment, state what failed and why, separating storm damage from pre-existing wear, and put it on company letterhead. If the condenser was crushed by a limb or flooded, we’ll also quote the replacement on the same visit so the claim has a number attached.

Our house near Lake DeSoto is from the 1910s with no ducts. What are the options that don't wreck the plaster?

Ductless mini-splits are the usual answer: one outdoor unit, slim indoor heads, and a three-inch hole per room instead of soffits. High-velocity small-duct systems are the other route when heads aren’t wanted on the walls. In the downtown historic area, check placement of the outdoor unit against any visibility guidelines before the pad is poured.

Crosswinds has deed restrictions. Will the covenants care where the new outdoor unit goes?

Often, yes. Deed-restricted subdivisions commonly require the condenser in a side or rear yard and screened from the street. We read the covenants with you before the estimate and position the unit so it passes, which is cheaper than moving it later.

Our well water leaves orange stains. Is it hurting the air conditioner too?

The condensate an air conditioner makes is pulled from the air, so the well doesn’t touch it. But a whole-home humidifier fed by well water scales fast, rinsing the outdoor coil with hose water leaves iron on the fins, and any water-cooled or open-loop geothermal equipment suffers. Tell us you’re on a well and we plan around it.

I own three rentals around Florida Gateway College. Who do you talk to when a tenant calls?

The tenant can schedule and let us in; the owner approves anything with a cost. We keep an authorization on file so a midnight no-cool call doesn’t stall waiting for you, up to whatever limit you set. The invoice and report go to you.

We're only at our Cannon Creek Airpark house part of the year. What should the thermostat do while we're gone?

Leave it running, set around 78 to 80 in summer and a humidity ceiling if the thermostat supports one. Shutting the system off for a month in July invites mold. A thermostat that sends alerts for high humidity or a dead system is worth the money for a house with a hangar attached.

The back bedrooms of our 1978 block ranch never cool. Is a bigger unit the answer?

Almost never. A bigger unit short-cycles and leaves the house damp. The problem is usually duct: undersized runs, a single return in the hall, flex that has sagged in a 130-degree attic. We measure airflow at each register and fix the delivery before anyone talks about tonnage.

Our manufactured home on acreage has duct under the floor. Why is the bill so high?

Belly-board duct is thin, often uninsulated, and gets crushed or torn by animals and settling. Cooled air ends up under the house instead of in it. Sealing and insulating that duct, or replacing it, is frequently the best money spent before any equipment change, and a qualifying heat pump may earn Clay Electric’s rebate.

Does the two-hour drive from Palm Coast mean I'll be charged for the trip?

No. The diagnostic fee is the same figure quoted to a customer near the shop, and there’s no mileage line and no after-hours surcharge. The drive is our cost of serving Columbia County, not yours.

My heat pump's auxiliary heat light is on every cold morning in January. Is something broken?

Not necessarily. Below the mid-30s a heat pump needs help, and Lake City sees those mornings often. Trouble starts when auxiliary heat runs at 50 degrees, or runs all day, which points to a low charge, a stuck reversing valve or a thermostat set up wrong. A fall tune-up is where that gets caught.

The ground near our slab has settled and there's a crack. Can that hurt the air conditioner?

It can. Columbia County sits on karst, and when a slab or pad shifts, the copper line set between the air handler and the condenser takes the strain. A slow refrigerant leak at a bent joint is the usual result. If the pad has moved, have the line set checked before summer.

Is natural gas heat an option in Lake City?

Inside the city, yes: Lake City Utilities runs a natural gas system, so a gas furnace or a dual-fuel setup pairing a heat pump with a gas furnace is realistic. Outside the limits it means propane, which changes the economics; we’ll run both against an all-electric heat pump for your address.

Every March the filter is yellow in two weeks. Is that normal?

For Lake City, yes. Pine pollen and oak catkins load filters and outdoor coils from late February through April. Change the filter monthly through spring, rinse the outdoor coil gently from the inside out, and consider a thicker media filter if the house has allergy sufferers.

Which electric utility am I on, and why does Cook's ask?

Inside Lake City, Five Points and Watertown it’s FPL; most of the unincorporated county is Clay Electric Cooperative; the far west is Suwannee Valley Electric. We ask because each one runs a different rebate program and because co-op lines and city lines behave differently in a storm, which affects what surge protection we recommend.
