A fifteen-year-old furnace in The Hammock has one good repair left in it, maybe two

Fifteen winters in a 1910 house

The Hammock, the 23-block South Historic District that was once the most desirable address in Palatka, has a particular kind of furnace. It went in during a renovation fifteen or so years ago, in a utility room or a closet that was never meant for it, in a house with high ceilings and original windows. It has lit every December since. This year it lit, ran for a minute, and shut down. Then it did it again.

Palatka heats for a dozen or so freezes a winter, so that furnace has not worked especially hard. But fifteen years of Florida summers have rusted its cabinet, its igniter has cycled thousands of times, and its control board has ridden out fifteen lightning seasons. It is at the fork, and the right answer depends entirely on which part gave up.

The branches, in the order we take them

Cook’s runs a furnace repair call the same way every time, and says each step aloud so the homeowner knows where the decision is heading.

1. Safety before anything. Carbon monoxide at the registers, combustion analysis at the flue, the condition of the venting, and a camera look at the heat exchanger. A cracked exchanger or CO in the house ends the repair discussion; the furnace stays off and we move to replacement.
2. The small, common failures. Igniter, flame sensor, pressure switch, limit switch, blower capacitor, a clogged condensate trap on a high-efficiency unit. These are inexpensive, usually on the truck, and age does not change the answer: fix it.
3. The mid-size failures. Inducer motor, blower motor, gas valve, control board. At fifteen years we quote the repair and also hand over a free replacement estimate, because two of these in a row would exceed what the furnace is worth.
4. The fuel question. On a propane furnace in the county, where the fuel is expensive, a mid-size failure tips faster toward a heat pump replacement than it does on a Palatka Gas Authority natural gas line in town.
5. The cooling side. Most furnaces here share an air handler cabinet and a coil with the air conditioner. If the coil is leaking or the blower is shared and failing, the whole system is in the conversation, not just the furnace.
6. The house. A furnace in a historic home with a single undersized return and leaky soffit duct will keep tripping its limit switch no matter how many parts go in. We say so.

Furnaces we work on in Putnam County

Cook’s is a Lennox dealer and installs Lennox two-stage and variable-capacity gas furnaces, but furnace repair covers whatever is in the house: Carrier, Bryant, Trane, Rheem, Goodman, York, Amana, American Standard and the rest. We also service the older equipment this county still has in quantity:

Type	Where we see it	Repair reality
Natural gas furnaces	City and near-city homes on Palatka Gas Authority lines	Full repair capability; parts for most brands on the truck or next-day
Propane furnaces	Rural lots, lake and river properties	Full repair; fuel cost often favors replacement with a heat pump when a big part fails
Gas floor and wall furnaces	North and South Historic Districts, Palatka Heights, Newtown	Serviced where parts exist and the unit passes safety checks
Electric furnaces and strip heat	Older air handlers, manufactured homes	Element, sequencer and limit repairs
Oil furnaces	Rare	Service by arrangement [[CONFIRM WITH JERRY]]

What the warranty will and will not cover at fifteen

A furnace heat exchanger usually carried a long parts warranty when new, often twenty years or lifetime on premium models, while the rest of the furnace carried five or ten years on parts. At fifteen:

• The heat exchanger may still be covered for the part, if the furnace was registered. That does not make a cracked exchanger a sensible repair: the labor to replace one is substantial, and the rest of the furnace is fifteen years old. It usually makes more sense to apply the money toward a new unit.
• Everything else is out of warranty. Igniters, boards, motors and valves are paid repairs.
• Cook’s repairs carry their own warranty on the part and the workmanship, stated on the invoice. Ask for the labor term before the work starts. [[CONFIRM WITH JERRY]]
• A gas leak or CO finding is documented in writing, whatever you decide, because the next owner of a Hammock house will want to see it.

Paying for the repair, or for the replacement

A furnace repair is quoted after the diagnosis and before the part goes in, and the price is the same at midnight as at noon. If the branch lands on replacement, three things are worth knowing in this county.

Financing with low monthly payments is available on new high-efficiency heating systems; terms are discussed in person. Palatka Gas Authority publishes an appliance rebate for homes installing a qualifying natural gas furnace, which can matter for a house already on its lines; ask whether Cook’s handles that paperwork. [[CONFIRM WITH JERRY]] And the federal 25C credit for high-efficiency furnaces ended for equipment placed in service after December 31, 2025, so it does not belong in anyone’s math.

For a lot of Palatka homes, the honest replacement is not another furnace at all but a heat pump, which heats the dozen cold mornings adequately and takes over the eight months of cooling as well. For the Hammock house that started this page, the igniter was the fault, the exchanger was sound, and the repair was the right call. One good repair left, used well. The next one will be a different conversation, and we said so before we left.
