A heat pump turns twenty in Sherwood Forest: the decision tree we use

Two subdivisions, two decades of equipment

Sherwood Forest went in across the 1970s, 80s and early 90s: brick-front and siding ranches on quarter-acre lots, carports and later garages, no homeowners association, city water, FPL power. River Woods followed in the late 1990s and 2000s with larger single-family homes, some two-story, attic air handlers and ductwork that was decent when new.

Air conditioners here last fifteen to twenty years, so Sherwood Forest is on its second or third generation of equipment and River Woods is on its first replacement wave. Different neighborhoods, same moment.

The fork at fifteen years

When a system in either neighborhood fails, we walk one decision tree, out loud, with you standing there.

1. How old is it? Under twelve, repair almost always wins. Twelve to fifteen, it depends on the part. Past fifteen, we need a good reason to put major money into it.
2. What failed? Capacitors, contactors, fan motors, drain problems and control boards are repairs at any age. Compressors and evaporator coils are the parts that swing the answer.
3. What refrigerant is in it? Older units on the phased-out refrigerant make a coil leak expensive to fix properly. Systems on the current refrigerant are still repairable at reasonable cost.
4. How is the ductwork? If the attic duct in a River Woods two-story is crushed and leaking, a new unit alone will disappoint. If a Sherwood Forest ranch has one return for the whole house, the same.
5. What does the repair cost against a new system? Our rule is plain: a repair above roughly a third of a correctly sized replacement, on a unit past fifteen, loses on arithmetic.

Why the big unit next door isn’t the answer

Here is the most common mistake we see corrected too late in Sherwood Forest. A 1,600-square-foot ranch had a two-and-a-half-ton system. It struggled one August, so the next installer put in a four-ton. Now the house cools in minutes, the system shuts off, and nobody can figure out why it feels like a locker room at 73 degrees.

The answer is that cooling and drying are two different jobs, and drying needs run time. The oversized system never gets any. In an inland climate with near-daily afternoon storms from June into September, the humidity load is at least as important as the temperature load, and the right size, often equipment that can throttle down to a lower stage or a slower compressor speed, is what beats it.

FPL inside the city limits

Both neighborhoods are on FPL rather than the co-op that serves most of Suwannee County, which changes the incentive conversation. FPL’s residential air-conditioning rebate gives an instant credit on qualifying high-efficiency systems, paid through contractors enrolled in its program; current terms and the minimum efficiency rating change, so we confirm them at quote time. Whether Cook’s is enrolled is something to ask us directly [[CONFIRM WITH JERRY]].

What a replacement visit looks like on these streets

A Sherwood Forest or River Woods changeout is usually a single long day: the old outdoor unit and blower cabinet out in the morning, pad leveled or replaced, line set flushed or run new, the new system set and charged by weight, the drain re-routed with a float switch, the thermostat replaced, and the ductwork sealed where we found it leaking during the estimate. We size from the structure rather than from the plate on the old unit, which in Sherwood Forest often means a smaller unit than the one coming out.

Sherwood Forest and River Woods are reached from Cook’s Palm Coast shop, 144 miles and two hours forty-five on I-10. Day or night, the call is answered and priced the same, and a replacement quote costs nothing.
