Hardwood is ready when its moisture matches your air-conditioned Florida home, on no fixed schedule, and LVP depends on the brand: COREtec needs none in a climate-controlled home, while Mohawk SolidTech calls for 48 hours in the room. Tile needs none, laminate varies by brand, and every one of these rules assumes the AC is already running in the house.
How long does flooring need to acclimate in a Florida home?
It depends on the floor type and the brand: some products need no waiting period, some name a fixed number of hours, and hardwood takes as long as the boards need to match the house. The instructions for your exact product outrank anything general; here is what the National Wood Flooring Association (NWFA) and three representative brands say.
| Floor type | What the source says about acclimation | What it means in a Florida house |
|---|---|---|
| Solid hardwood | No set time. When boards arrive at a moisture content matching normal living conditions and the manufacturer's requirements, the subfloor agrees, and those conditions are maintained, the flooring may be installed immediately (NWFA Installation Guidelines, 2025 revision). | Ready when the meter says so, after the house is at living conditions. |
| Engineered hardwood | Follow the manufacturer's moisture testing and acclimation instructions to keep warranty coverage (NWFA engineered wood section). | The carton insert sets the rule. |
| LVP / SPC: Mohawk SolidTech | Acclimate 48 hours in the room of installation at 55–85°F, with humidity below 65% for 48 hours before, during and after installation (SolidTech installation instructions, 08/2025). | The planks wait in the cooled room where they will be installed. |
| LVP / SPC: COREtec | Acclimation before installation is not required; the floor should be installed in a climate-controlled environment between 55 and 85°F (COREtec residential SPC installation guidelines). | Climate-controlled means the AC is already running. |
| Laminate: Shaw | No acclimation when site conditions are met: HVAC fully operating 7 days before, during and after installation, 35–65% relative humidity and 65–85°F (Shaw laminate installation page). | The waiting happens in the house, with the AC running ahead of time. |
| Porcelain and ceramic tile | No acclimation step. | The slab and the thinset maker's instructions set the schedule. |
Every one of these rules assumes the home is already cooled and dehumidified. In Florida, getting the AC running ahead of delivery matters more than how many days the boxes sit.
What moisture content should hardwood reach in a Florida house?
The target is whatever the house will hold once you live in it. The NWFA guidelines cite USDA Forest Products Laboratory figures: interior wood averages 8% moisture content in most of the U.S. (range 6–10%) and 11% in damp, warm coastal areas (range 8–13%), and warn that actual homes can differ significantly.
For solid wood, the NWFA's general rule, with geographic exceptions, is 30–50% relative humidity at 60–80°F; in some climates, it notes, the ideal average range runs higher, 45–65%. Some manufacturers deliberately produce flooring at a higher 8–13% moisture content to suit different regions (NWFA interior conditions). Ask which target your product was made for.
Wood settles toward an equilibrium moisture content (EMC) set by the room's temperature and humidity. Rows from the USDA table the NWFA reprints show why the AC matters:
| Indoor RH at 70°F: wood moisture content (EMC) | Against the NWFA ranges |
|---|---|
| 40% RH: 7.7% (NWFA EMC table) | Inside the general range, below the humid-climate range |
| 50% RH: 9.2% (NWFA EMC table) | Inside both ranges |
| 60% RH: 11.0% (NWFA EMC table) | Inside the humid-climate range only |
| 70% RH: 13.1% (NWFA EMC table) | Above both ranges |
| 80% RH: 16.0% (NWFA EMC table) | Well above both ranges |
A closed-up house in a humid month reads toward the bottom rows; a house with the AC cycling normally reads toward the top. Boards that acclimate in the first and live in the second shrink after installation. The damage that follows is covered in our post on why hardwood floors cup and buckle in Florida.
Does engineered hardwood need to acclimate as long as solid?
Not necessarily. The NWFA keeps the same room and subfloor checks for engineered as for solid, then leaves the acclimation rule to the flooring manufacturer, as the first table shows.
Engineered boards are built in cross-layers, so they move less with humidity than solid boards. The top layer is still real wood, so the meter readings still count. Over a Florida slab, engineered is the hardwood we generally recommend, and the slab moisture test comes before any talk of waiting days.
Which of the two suits your house is answered in our engineered vs solid hardwood guide for Florida. When we install engineered or solid hardwood, the readings go on the written record before the first board goes down.
Does LVP or SPC flooring need to acclimate at all?
Sometimes. The two vinyl instructions in the first table disagree; each rigid-core brand writes its own rule, and the insert in your carton is the one the warranty follows.
LVP and SPC don't soak up humidity the way wood or laminate's fiberboard core does; they grow and shrink with temperature. Planks that rode in a hot truck or sat in a Florida garage need to reach room temperature before they are locked together, even under a no-acclimation brand, because that exemption assumes a climate-controlled room.
Two Florida habits to break: parking cartons in the garage until install day, and stacking them against a slider in afternoon sun. With vinyl, the room the planks wait in matters more than the number of hours. Plank grades and prices are on our luxury vinyl plank installation page.
How long should laminate acclimate before it goes down?
It depends on the brand and on what your hygrometer reads. Laminate's fiberboard core reacts to humidity in a way vinyl does not, which is why the Shaw rule in the first table is written around relative humidity.
Read the Shaw line closely: no acclimation applies only when the house already meets its conditions, with the HVAC running for days ahead, so the waiting moves from the cartons to the house. Other laminate brands set a waiting period in sealed cartons in the installation room, so the insert in your carton decides.
Over a slab we put a vapor-barrier underlayment under laminate; on our laminate flooring installation page that line item runs $1–$1.75/sq ft. Whether laminate belongs in your house at all is covered in our ranking of the best flooring for Florida humidity.
Should flooring boxes be opened while they acclimate?
For wood, only when the moisture content needs to move. The NWFA says adjusting solid wood's moisture content may be necessary when the product does not match the home's expected living conditions, or in extreme environments; then the flooring is split into small lots or unwrapped and cross-stacked with 3/4" to 1" spacers so air reaches every board. It cautions that forcing moisture in or out can swell or shrink boards beyond their milled size, and that imported and tropical species often take two to three times longer to equilibrate than most domestic species (NWFA acclimation chapter).
For laminate and vinyl, the carton insert decides whether boxes stay sealed while they wait. Wherever cartons sit, they belong in the room where they will be installed, inside the conditioned space and out of direct sun.
Can flooring acclimate in a new build before the AC is running?
No. Acclimating to a house with the AC off matches the flooring to air it won't live in once the AC is on. The NWFA guidelines say HVAC should run for at least 5 days before wood flooring is delivered, and longer may be necessary with tighter building envelopes and wet conditions; those conditions should hold before, during and after installation. Wood flooring should not be delivered, stored or opened in a building without controlled conditions.
In new construction, wet trades come first: the NWFA lists concrete, masonry, plastering, drywall, texturing, painting and power washing as work to complete before wood arrives. And a new slab is still drying; the NWFA says regular testing of a drying slab may begin 30 days after placement (NWFA moisture testing chapter). On new builds we schedule delivery once the AC has been running at normal living settings.
What moisture readings should be logged before install day?
Four kinds, each written down with date and location. The NWFA says to record, date, photograph and document results, and describes data loggers left on site to track conditions (NWFA moisture testing chapter).
| Reading | How it is taken and the limit (source) | Why it matters in Florida |
|---|---|---|
| Room temperature and relative humidity | Thermo-hygrometer or data logger, before and at delivery and during the install, against the manufacturer's range. | Shows whether the AC has the house at living conditions. |
| Solid wood flooring moisture content (engineered: per the manufacturer) | At least 40 boards from several bundles for the first 1,000 sq ft plus 4 per additional 100 sq ft, averaged and compared with the EMC for the room (NWFA). | Boards reading unusually high or low get set aside. |
| Wood subfloor moisture content | At least 20 locations for the first 1,000 sq ft plus 4 per additional 100 sq ft. In hot, humid climates and during the humid season, no more than 13%; where it is out of line with the room, the rule of thumb is no more than 4% above solid strip flooring under 3" wide and 2% above solid plank 3" and wider (NWFA). | Applies upstairs in two-story frame houses and in raised homes. |
| Concrete slab, in-situ RH probes (ASTM F2170) | Under wood, the NWFA strongly recommends more drying time or a class 1 impermeable vapor retarder above 80% RH (NWFA); Mohawk SolidTech calls for less than 90% RH (SolidTech instructions). | Slab-on-grade is the norm here, so this usually decides install day. |
| Concrete slab, calcium chloride (ASTM F1869) | Under wood, the NWFA strongly recommends more drying time or a membrane above 3 lbs per 1,000 sq ft per 24 hours (NWFA); Mohawk SolidTech requires 8 lbs or less (SolidTech instructions). | Both slab tests call for controlled room conditions before testing. |

This is general information; your product's installation instructions and the manufacturer's technical support line have the final word on acclimation and moisture limits.

Frequently Asked Questions
Can I keep the flooring boxes in my garage until install day?
No. Wood flooring should not be stored anywhere without controlled temperature and humidity, and vinyl and laminate instructions set room conditions that a Florida garage in summer can't be counted on to meet. Move the cartons into the rooms where they will be installed, with the AC running.
Is 72 hours enough time to acclimate hardwood?
Only if the moisture meter agrees. Hardwood is ready when its moisture content matches the home's normal living conditions, which can happen on delivery day or take longer. The clock that matters starts once the AC is running at normal settings.
Should I turn the AC off or down while new flooring acclimates?
No. Run the AC at the settings you will actually live with, because that is the condition the flooring is matching. Shutting it off, or setting it unusually cold for the occasion, gives the boards a target they will drift away from after the install.
Can LVP be installed the same day it's delivered?
With some brands, yes, as long as the planks are already at room temperature in a climate-controlled house. Other brands require a waiting period in the room of installation. The insert in your carton is the rule the warranty follows.
Do porcelain or ceramic tiles need time to adjust before installing?
No. Tile does not swell or shrink with humidity the way wood does, so there is no acclimation period. What matters is a flat, sound slab and following the thinset manufacturer's mixing and temperature instructions.
Can skipping acclimation void a flooring warranty?
It can. Mohawk's SolidTech instructions, for example, say the product must be installed as written so as not to void its warranties. Keep the written moisture readings with your receipt in case a claim ever comes up.
Who takes the moisture readings, me or the installer?
The installer. Taking and recording readings of the room, the flooring and the subfloor is part of a professional install, and the results should be written down and kept with your paperwork. Your part is having the AC running at normal settings before delivery.
