Which Lennox system fits the house you own in Palm Coast
An overview of what we install, who each piece suits, and how we size it for a Flagler County floor plan. Start here if you don't yet know whether you need an air conditioner, a heat pump or both.
A thermostat stuck at 80 in Cypress Knoll
Four in the afternoon on a Thursday in August. The thermostat on a golf-course street in Cypress Knoll is set to 76 and has read 80 since lunch. The outdoor unit by the pool cage has run without a break since nine. The house was finished in 2005 and so was the system, which makes it twenty-one years old this summer.
That homeowner doesn’t need a lecture about SEER ratings. They need to know which of the boxes on this page they should be looking at. So this page is organized by house, not by product.
Who each piece of equipment is for, section by section
Air conditioners (cooling only, paired with an air handler that carries electric heat strips) suit homes where the few cold nights each winter are handled by strips and nobody minds the FPL bill on those nights. Common across Indian Trails and Belle Terre.
Heat pumps do the same cooling job and reverse in winter, moving heat instead of making it with resistance coils. For a Palm Coast house that runs cooling March to November and heat for a few weeks in January, this is the default recommendation.
Air handlers are the indoor half of either system. If the outdoor unit is being replaced, the air handler almost always should be too, and this is where the 2004-2007 build-out bites: thousands of attic air handlers are the same age as the condensers they’re paired with.
Furnaces matter only where Peoples Gas runs a line to the house or a propane tank sits on the property. That’s a minority of the city.
Mini-splits handle the converted lanai, the garage office and the bonus room over the garage, all common in Quail Hollow and Seminole Woods.
Packaged units sit on older Bunnell and west-county homes and on commercial rooftops around Town Center.
Indoor air products (filtration, dehumidification, purification, ventilation) bolt onto any of the above and are covered on their own pages.
Condenser, coil, blower, thermostat: one machine
An air conditioner or heat pump is two halves and a thermostat. The outdoor unit rejects heat to the yard; the indoor coil absorbs it from the house and, in this climate, wrings out water along the way. A Palm Coast summer day with a dew point in the mid-70s can send several gallons an hour down the condensate line. The drain, the float switch and the pan are not accessories here; they are part of the system.
Sizing for a Palm Coast floor plan
We size from a load calculation, not from the nameplate on the old unit and not from square footage alone. Inputs that move the number in this city:
- Orientation and glass. A west-facing lanai wall in Grand Haven changes the afternoon load more than an extra bedroom would.
- Ceiling insulation. Many boom-era attics came with the minimum; FPL offers a free Home Energy Survey that will tell you what’s up there.
- Duct condition. ITT-era homes in Palm Harbor and the Woodlands often have attic duct that leaks enough to justify sealing before any new equipment goes in.
- Occupancy and schedule. A retiree couple home all day and a commuting family produce different loads.
Oversizing is the most common mistake we undo. It shows up as a house that’s cold but damp, and as a compressor that starts twenty times a day.
Efficiency tiers and the FPL rebate
Higher-efficiency equipment costs more up front and earns it back in two places: the monthly bill from March to November, and the FPL instant rebate on qualifying high-efficiency systems installed by a participating contractor. The federal credit stopped with the 2025 calendar, so the rebate is the incentive that still counts. Cook’s can set a new high-efficiency system up as monthly installments, and pricing one costs you nothing. We’re a Lennox dealer, so the quotes you’ll see are built around that line, but we’ll tell you plainly when a simpler tier is the better buy for your house.
Choosing equipment: questions from across the city
Can I replace just the outdoor unit and keep my 2005 air handler?
Sometimes, but it’s rarely the right move. The coil in that air handler was matched to a different refrigerant and a different efficiency standard, and mismatched halves lose efficiency and can void the warranty on the new half. We’ll quote both ways so you can see the gap.
Which Lennox tier makes sense for a rental in Palm Coast?
A single-stage system with a solid warranty and a float switch on the drain. Tenants don’t maintain filters the way owners do, so simple and tough beats sophisticated. Save variable-speed equipment for the house you live in.
Does a bigger system cool a Lehigh Woods two-story faster?
It cools the thermostat faster and the upstairs worse. An oversized unit satisfies the downstairs sensor in minutes, quits before much moisture has been wrung out, and leaves the second floor warm and sticky. Correct sizing, and often zoning, is what fixes a two-story.
Which Lennox systems carry the FPL instant rebate?
The ones that clear FPL’s efficiency bar for its Residential HVAC Program, installed by a participating contractor. The qualifying list changes, so we check it against the exact model on your quote rather than promising from memory.
