Most new homeowners complete a thorough pre-closing process. The duct system gets none of that scrutiny. It runs, it produces airflow, it passes the mechanical check — and then it spends the first months of your occupancy circulating whatever the previous owners left behind through every room in your new home.
We've walked into newly purchased Altamonte Springs homes immaculate by every visible standard — fresh paint, deep-cleaned surfaces, new filters installed for closing day. What we found inside the duct runs told a different story. Years of Central Florida humidity, previous occupancy conditions, and near year-round AC runtime had produced contamination levels that no surface cleaning addressed and no pre-closing inspection surfaced.
Why new Altamonte Springs homeowners need a dedicated duct cleaning checklist:
Standard home inspections evaluate mechanical function — not what the system is circulating
Central Florida's climate accelerates duct contamination faster than any national guideline accounts for
Previous occupancy factors — pets, smokers, renovation debris, deferred maintenance — transfer invisibly at closing
Pre-move-in is the most practical window for duct evaluation — it closes the moment furniture arrives

TL;DR Quick Answers
Duct Cleaning Checklist for New Homeowners in Altamonte Springs FL
Most new Altamonte Springs homeowners need professional duct cleaning before move-in. The standard pre-closing process evaluates mechanical function — not what the inherited duct system is actually circulating. In this climate, that distinction matters more than most buyers realize until after they've moved in.
What new Altamonte Springs homeowners are inheriting at closing:
Unknown duct history from previous occupancy — zero documentation in most resale transactions
Biological growth conditions created by years of humidity above the 50% threshold
Near year-round AC runtime with no seasonal recovery period
Pre-sale renovation debris that no staging crew or inspector addressed
Contamination recirculating up to 7 times daily from the first moment the system runs
The pre-move-in inspection checklist — two locations, fifteen minutes:
At registers and return grilles:
Visible dust buildup on grille surfaces
Dark staining around register edges
Any visible debris inside duct openings
Loose or missing register covers
At the air handler:
Filter condition — loaded or degraded filter reveals previous owner's maintenance standard
Visible mold or biological growth at cabinet or evaporator coil
Dust accumulation on blower compartment
Any moisture or rust around the unit
Central Florida climate adjustments every new homeowner must apply:
Year-round AC operation — 11 months of continuous runtime with no recovery period
Humidity regularly exceeds 50% — active biological growth threshold
Near-continuous pollen seasons — no defined off-season in this market
National 3–5 year guideline is a starting point — not a standard — in Altamonte Springs
Post-move-in filter strategy from day one:
MERV 8 minimum — every Altamonte Springs home
MERV 11 — pets, allergy sufferers, older duct systems
Change every 60–90 days — every 30–45 days with pets or allergy sufferers
Monitor filter loading at 30, 60, and 90 days after pre-move-in cleaning
Before booking any provider under move-in pressure:
Verify Florida contractor license — MyFloridaLicense.com
Verify NADCA certification — nadca.com/find-a-professional
ZIP codes served by Altamonte Springs duct cleaning providers: 32701 · 32714 · 32716 · 32751
Top Takeaways
The standard move-in checklist was never designed to evaluate the one system circulating air through every room.
Utilities, appliances, locks, surfaces — all covered
The duct system — invisible by design, absent from every pre-closing checklist
In Altamonte Springs, that gap carries consequences no other checklist item produces
Whether the system runs and what it circulates are two different questions — only one gets answered before closing day
You're inheriting a duct system Central Florida's climate has been working on for years.
Florida's humidity exceeds the 50% biological growth threshold continuously
Pre-sale renovation left construction debris no staging crew addressed
Near year-round AC runtime means contamination compounds with no seasonal recovery
Well-maintained homes surprise buyers most — the climate outpaced what the previous owner did right
Pre-move-in is the only window where timing, access, and benefit align perfectly.
Full system access before furniture blocks registers
Cleaning debris settles on nothing — because nothing is there yet
Family starts clean from day one
This window closes the moment the moving truck arrives
The six-step checklist gives new Altamonte Springs homeowners the evaluation framework the move-in process never provided.
Request cleaning history and occupancy documentation from seller before closing
Conduct targeted visual inspection at registers and air handler before move-in
Apply Central Florida's climate adjustments to any national guideline encountered
Identify specific risk factors — pets, smokers, renovation history, vacancy periods
Verify Florida contractor license and NADCA certification before booking anyone
Establish MERV 8 or higher filter strategy from day one — monitor first 90 days
Verify before booking anyone — especially under move-in time pressure. Two checks — under two minutes:
Florida contractor license — MyFloridaLicense.com
NADCA certification — nadca.com/find-a-professional
Move-in pressure is when unqualified operators are most active. These two verifications protect new Altamonte Springs homeowners before anyone opens their duct system for the first time.
Step 1: Understand What You're Inheriting Before You Evaluate It
Every new Altamonte Springs homeowner starts from the same position: zero visibility into the duct system's actual history.
What the seller disclosure typically covers — and what it doesn't:
Covered: Major mechanical defects, known system failures, equipment age
Not covered: Last professional duct cleaning date, previous occupancy conditions, renovation debris inside ductwork, biological growth history
What previous occupancy factors transfer invisibly at closing:
Pet dander and hair — accelerates filter loading and duct buildup faster than almost any other contaminant
Smoke residue — coats duct surfaces and doesn't clear with filter changes alone
Renovation debris — drywall dust infiltrates duct systems during construction and doesn't clear on its own
Deferred filter maintenance — low-MERV filters changed infrequently accelerate contamination at every stage
Vacancy periods — systems that sit idle in Florida's humidity develop biological growth faster than maintained ones
What to request from the seller before closing:
Documentation of last professional duct cleaning
Confirmation of previous occupancy factors — pets, smokers, renovation history
Records of filter maintenance schedule and MERV rating used
Any history of moisture, mold, or pest issues in the home
If documentation doesn't exist — assume it hasn't been done. In Central Florida's climate, that assumption is almost always the safer starting point when planning professional duct cleaning services for your home's HVAC system.
Step 2: Conduct a Visual Pre-Move-In Inspection
Before furniture arrives and before the first night in your new home, a targeted visual inspection at key points in the system takes less than fifteen minutes and tells you more than the mechanical inspection did about what's actually there.
At every supply register and return grille — look for:
Visible dust buildup on grille surfaces — indicates filtration gaps or deferred maintenance
Dark staining or discoloration around register edges — consistent indicator of particulate-carrying airflow over time
Any visible debris inside the duct opening — immediate red flag regardless of home age
Loose or missing register covers — gaps that allow unfiltered air and debris to enter the system directly
At the air handler — look for:
Filter condition — a heavily loaded, collapsed, or visibly degraded filter is the single clearest indicator of the previous owner's maintenance standard
Visible mold or biological growth at the air handler cabinet or evaporator coil
Dust accumulation on the blower compartment — indicates how long the system has operated without professional attention
Any signs of moisture, rust, or water intrusion around the unit
What the visual inspection tells you:
Two or more indicators present — schedule professional cleaning before move-in
Single indicator present — professional inspection warranted before making a final decision
No indicators present with documented cleaning history — cleaning may hold; monitor closely during first 90 days
Step 3: Apply Central Florida's Climate Factors to Your Specific Home
National duct cleaning guidelines were not written for Altamonte Springs. A new homeowner applying those standards to a Central Florida property is starting from the wrong baseline.
The three climate adjustments every new Altamonte Springs homeowner needs to make:
Adjustment 1 — Runtime National guidelines assume seasonal HVAC operation. Altamonte Springs systems run approximately 11 months annually. Apply a runtime multiplier to any national cleaning frequency recommendation — what takes five years to accumulate in a seasonal climate takes closer to three in Central Florida.
Adjustment 2 — Humidity The EPA recommends indoor relative humidity between 30–50%. Seminole County's outdoor humidity routinely exceeds 50% for extended periods. Every year of previous occupancy in this climate is a year the duct system operated in biological growth conditions — regardless of how well the home was otherwise maintained.
Adjustment 3 — Pollen load National guidelines assume pollen seasons with defined start and end points. Central Florida's live oak, pine, and grass pollen cycles overlap almost continuously. Organic particulate loads duct systems here at a rate that seasonal markets never produce.
What these adjustments mean for your cleaning decision:
Home with unknown cleaning history + any occupancy risk factors = clean before move-in
Home with documented cleaning within last 2 years + no risk factors = visual inspection sufficient
Home with renovation history within last 5 years = clean before move-in regardless of other factors
Step 4: Identify Your Home's Specific Risk Factors
Climate sets the baseline. Your specific home's occupancy history determines where you land within — or outside — that baseline.
High-risk factors that make pre-move-in cleaning essential:
Previous pets — dander and hair accumulate faster than almost any other contaminant
Previous smokers — residue coats duct surfaces and doesn't clear with filter changes
Renovation or construction within last 5 years — drywall dust is the most damaging and most common finding in pre-purchase inspections
No documented cleaning history — zero visibility means worst-case assumption is the right starting point
Extended vacancy — biological growth develops faster in idle Florida systems than maintained ones
Home older than 10 years with no cleaning record — contamination levels consistently exceed what homeowners expect
Lower-risk factors where cleaning may hold:
Documented professional cleaning within last 2–3 years
No pets, smokers, or renovation history
Consistent MERV 8 or higher filter changes on record
Newer construction with no moisture or mold history
No extended vacancy periods
The honest rule we apply across every new homeowner consultation: If two or more high-risk factors apply — clean before move-in. If none apply and documentation exists — a thorough visual inspection is a reasonable starting point.
Step 5: Schedule and Verify Before Booking Anyone
Pre-move-in timelines create exactly the pressure that low-bid operators in this market count on. Moving fast, managing closing costs, coordinating utilities — the duct cleaning decision gets made quickly under conditions that favor the wrong provider.
The pre-booking verification checklist — both free, both under two minutes:
Florida contractor license — MyFloridaLicense.com
NADCA certification — nadca.com/find-a-professional
Questions to ask before confirming any booking:
Does the service cover the full system — supply ducts, return ducts, registers, and air handler?
Do you use truck-mounted or HEPA-filtered negative pressure equipment?
Will you provide before and after documentation?
Is pricing flat rate or per vent?
What legitimate pricing looks like in Altamonte Springs:
Standard single-system home: $300–$600
Dual systems or significant contamination: above $600
$79–$99 advertised specials: incomplete service — never the right choice under move-in pressure
Step 6: Establish Your Post-Move-In Filter Strategy
Pre-move-in cleaning removes what the previous occupancy left behind. What happens next depends entirely on the filter strategy you establish from day one.
The post-move-in filter baseline for Altamonte Springs homes:
MERV 8 minimum — filters particulate effectively without restricting airflow on most residential systems
MERV 11 — recommended for households with pets, allergy sufferers, or older duct systems
Change schedule — every 60–90 days in Central Florida's climate; every 30–45 days with pets or allergy sufferers
What consistent filter maintenance does for a newly cleaned system:
Slows recontamination rate — homes running MERV 8+ filters on schedule hold cleaning results closer to the 3-year mark
Reduces filter loading from year-round pollen and humidity-driven particulate
Provides an early warning system — a filter loading faster than expected signals a duct system issue before symptoms develop
The post-move-in monitoring checklist for the first 90 days:
Check filter condition at 30 days — loading rate tells you whether the cleaning held and what the system is pulling in
Conduct visual register check at 60 days — dust returning faster than expected warrants a follow-up inspection
Note any musty odors, allergy symptom changes, or airflow inconsistencies — these are the early indicators that warrant professional attention before the next scheduled cleaning
"The move-in checklist every new Altamonte Springs homeowner receives covers almost everything — except the one system that circulates air through every room in the house from the first moment it runs. We've walked into newly purchased homes that passed every pre-closing evaluation, showed clean registers on closing day, and had brand new filters installed for the final walkthrough — and found duct conditions inside that reflected years of Central Florida humidity, previous occupancy history, and near year-round runtime that no surface inspection was ever going to surface. The mechanical check tells you the system works. The duct inspection tells you what the system is doing with that function. In Altamonte Springs, top duct cleaning services help homeowners address those hidden conditions before the moving truck arrives — not months after your family has already been living with whatever was left behind."

Supporting Statistics
New Altamonte Springs Homeowners Inherit Indoor Air That Is 2–5x More Polluted Than Outdoor Air — From the First Moment the System Runs
This is the statistic we share first when new Altamonte Springs homeowners ask whether pre-move-in cleaning is really necessary.
Key facts:
EPA documents indoor air pollutant concentrations run 2–5 times higher than outdoor levels
Americans spend approximately 90% of their time indoors
For new homeowners — this isn't a system you've maintained. It's whatever the previous occupancy deposited before you arrived
What we find in newly purchased Altamonte Springs homes:
Fresh paint, clean registers, new filters installed for closing day — on the surface
Duct conditions inside that no pre-closing inspection captured
Contamination that started years before you moved in — not the day you turned the key
Year-round AC operation means contamination compounds continuously. No seasonal dilution. No recovery period. Ever.

Every Contaminant the Previous Owner Left Behind Begins Recirculating Through Your New Home Up to 7 Times Per Day — Immediately
This is the data point that reframes the decision from optional maintenance to immediate action.
Key facts:
NADCA research shows HVAC systems recirculate air 5–7 times daily
25–40% of heating and cooling energy lost when contaminants force systems to work harder
Pet dander, smoke residue, renovation debris, biological growth — all moving through living spaces before furniture is placed
What we measure in newly purchased local homes:
Improved airflow and reduced filter loading rates — consistent across every pre-move-in cleaning
Efficiency gains within the first billing cycle
Near year-round AC operation means no recirculation-free recovery period — ever
Homeowners who understood this data before move-in acted without hesitation. The ones who found out afterward wished they had.

The Duct System Your New Home Came With Has Been Operating in Biological Growth Conditions for Every Year of Its Previous Occupancy
This is the finding that surprises new Altamonte Springs homeowners most — especially those relocating from drier or seasonal markets.
Key facts:
EPA recommends indoor relative humidity between 30–50%
AAAAI confirms mold and dust mites actively thrive above 50%
Seminole County humidity routinely exceeds that threshold for extended periods
No seasonal correction — biological growth threshold exceeded continuously
What we find in newly purchased homes:
Consistent filter changes, clean surfaces, no obvious signs of neglect — on the outside
Biological growth inside panels reflecting years of Central Florida humidity
Conditions national maintenance standards were never designed to address
The new homeowners weren't prepared for it. The data, in hindsight, predicted it exactly.

The Renovation That Made Your New Home Show-Ready Left the Most Damaging Contaminant in the One Place Nobody Checked
This is the finding that consistently changes the conversation when new homeowners push back on pre-move-in cleaning for a recently renovated property.
Key facts:
CDC identifies renovation and construction as among the most significant sources of acute indoor air contamination
Poor indoor air quality directly contributes to respiratory health outcomes including aggravated asthma and allergy symptoms
Central Florida's humidity accelerates the impact of renovation debris inside ductwork vs. drier markets
What pre-sale renovation looks like in the Altamonte Springs resale market:
Updated kitchens, new flooring, fresh bathrooms — designed to photograph well
Duct system never on the renovation or staging checklist — not once
Drywall dust and construction debris infiltrate ductwork and don't clear on their own
What we find in renovated homes:
Renovation debris present 3–4 years after work was completed
Immaculate staging, flawless visible surfaces
Duct runs telling a completely different story
Central Florida's humidity compounding that debris since the last contractor left
New homeowners purchasing renovated properties are inheriting that story — whether they know it yet or not.

Final Thought & Opinion
The standard move-in checklist covers almost everything. The duct system isn't on it — and after walking into hundreds of newly purchased homes across Seminole County, we have a clear position on why that gap matters more here than almost anywhere else in the country.
Pre-move-in duct evaluation isn't a reflexive recommendation. It's a position we arrived at after seeing the same pattern repeat: attentive buyers, thorough pre-closing processes, standard inspections — and duct systems carrying conditions none of those steps were designed to surface.
What the data tells us:
Indoor air runs 2–5 times more polluted than outdoor air — inherited with zero visibility into its source
Inherited contamination recirculates up to 7 times daily from the first moment the system runs
Florida's humidity has been creating biological growth conditions inside that duct system for every year of its previous occupancy
Pre-sale renovation left construction debris no staging crew, inspector, or pre-closing checklist addressed
What the work tells us:
Well-maintained homes surprise buyers most — Central Florida's climate quietly outpaced everything the previous owner did right
Pre-move-in is the only window where timing, access, and benefit align perfectly — closes the moment the moving truck arrives
Homeowners who acted before move-in started clean — measurable improvements in airflow and efficiency from day one
Homeowners who deferred called us months later describing exactly what we would have found and fixed before move-in
Our opinion, plainly stated:
The move-in checklist was built around visible, actionable tasks. The duct system is invisible by design — it was never meant to appear on that list. In Altamonte Springs, invisible doesn't mean inconsequential. It means the opposite.
What we've learned in this market: the new homeowner duct cleaning decision isn't about cleaning — it's about information.
Every new Altamonte Springs homeowner deserves to know what they inherited before the first night in their new home:
Not because someone told them to clean it
But because they looked at their specific conditions, applied an honest framework, and made an informed decision
In a market where the climate, occupancy history, and pre-sale renovation practices consistently produce what we find when we open duct panels — informed decisions almost always lead to the same place.
The new homeowner duct cleaning checklist — condensed:
Request cleaning history and occupancy documentation from the seller before closing
Conduct a targeted visual inspection at registers and air handler before move-in
Apply Central Florida's climate adjustments to any national guideline you've encountered
Identify your home's specific risk factors — pets, smokers, renovation history, vacancy periods
Verify Florida contractor license at MyFloridaLicense.com and NADCA certification at nadca.com/find-a-professional before booking anyone
Establish a MERV 8 or higher filter strategy from day one — monitor loading rates during the first 90 days

FAQ: Duct Cleaning Checklist for New Homeowners in Altamonte Springs FL
Q: Do I need duct cleaning when moving into a new home in Altamonte Springs?
A: In most cases — yes. Timing matters more than most new homeowners realize until after they've moved in.
What makes the answer almost always yes in this market:
Zero visibility into what the inherited duct system actually contains
Central Florida's humidity creates biological growth conditions for every year of previous occupancy
Near year-round AC operation — contamination compounds continuously with no recovery period
Previous pets, smokers, renovation activity — transfer invisibly at closing, filter changes won't resolve them
When cleaning can reasonably wait:
Documented professional cleaning within the last 2–3 years
No pets, smokers, or renovation history confirmed by seller
Newer construction with consistent MERV 8+ filter maintenance on record
Visual inspection shows no indicators at registers or air handler
Our starting point for every new Altamonte Springs homeowner: if documentation doesn't exist — assume it hasn't been done. In this climate, that's almost always the safer call.
Q: What should I look for during my pre-move-in duct inspection in Altamonte Springs?
A: Two locations. Fifteen minutes. More information than the mechanical inspection provided.
At every supply register and return grille:
Visible dust buildup on grille surfaces — filtration gaps or deferred maintenance
Dark staining around register edges — consistent indicator of particulate-carrying airflow over time
Visible debris inside duct opening — immediate red flag regardless of home age
Loose or missing register covers — unfiltered air entry point into the system
At the air handler:
Filter condition — heavily loaded or degraded filter reveals previous owner's maintenance standard
Visible mold or biological growth at cabinet or evaporator coil
Dust on blower compartment — indicates how long system ran without professional attention
Moisture, rust, or water intrusion around the unit
How to read what you find:
Two or more indicators — schedule professional cleaning before move-in
Single indicator — professional inspection warranted before deciding
No indicators with documented history — cleaning may hold; monitor first 90 days
We've walked into homes with brand new filters installed for closing day — clean registers, nothing visible — and found contamination inside the duct runs the visual check was never going to surface. The fifteen-minute inspection is the right starting point. It isn't the complete answer.
Q: How does Central Florida's climate affect the duct cleaning decision for new Altamonte Springs homeowners?
A: It changes the baseline entirely. Homeowners relocating from seasonal markets consistently underestimate this until we show them what we find.
Three climate factors that override every national guideline:
Year-round AC operation — approximately 11 months of continuous runtime. No seasonal shutdown. What takes five years in a seasonal climate develops closer to three here — sometimes faster.
Persistent humidity above biological growth thresholds — Seminole County exceeds 50% humidity for extended periods. Every year of previous occupancy is a year that the duct system operated in active mold and dust mite growth conditions.
Near-continuous pollen seasons — live oak, pine, and grass cycles overlap almost continuously. No defined start and end — the organic particulate buildup we find in local systems reflects it consistently.
What this means in practice:
National 3–5 year guidelines are a starting point — not a standard — in this market
Unknown duct history — apply the 3-year end of that range at minimum
Any occupancy risk factors push that timeline earlier — not later
Q: What questions should I ask a duct cleaning company before booking a pre-move-in cleaning in Altamonte Springs?
A: Start with two verifications before the conversation begins. Move-in pressure is when unqualified operators are most active in this market.
Two non-negotiables:
Florida contractor license — required by law for partial system disassembly. Verify at MyFloridaLicense.com

Does service cover the full system — supply ducts, return ducts, registers, and air handler?
Do you use truck-mounted or HEPA-filtered negative pressure equipment?
Will you provide before and after documentation?
Is pricing flat rate or per vent?
How long does cleaning take for a home this size?
How to read the answers:
Full-system coverage, negative pressure equipment, flat-rate pricing, 2–4 hours — qualified provider
Vague scope, per-vent pricing, resistance to documentation, under 90 minutes — keep looking
Pricing in this market:
Standard single-system home: $300–$600
Dual systems or significant contamination: above $600
$79–$99 specials: incomplete service — avoid under any move-in timeline
We've heard from new homeowners who asked these questions and watched a provider leave rather than answer them. Under move-in pressure — with time still to find someone qualified — that told them everything they needed to know.
Q: How do I set up a filter maintenance strategy after pre-move-in duct cleaning in Altamonte Springs?
A: Pre-move-in cleaning removes what the previous occupancy left behind. The filter strategy you establish from day one determines how long that cleaning holds.
Post-move-in filter baseline for Altamonte Springs homes:
MERV 8 minimum — effective filtration without restricting airflow on most residential systems
MERV 11 — recommended for pets, allergy sufferers, or older duct systems
Change schedule — every 60–90 days in Central Florida; every 30–45 days with pets or allergy sufferers
What consistent filter maintenance does for a newly cleaned system:
Slows recontamination — MERV 8+ changed on schedule holds results closer to the 3-year mark
Reduces loading from year-round pollen and humidity-driven particulate
Creates early warning system — faster loading signals a duct issue before symptoms develop
First 90-day monitoring checklist:
Day 30 — check filter condition. Loading rate confirms whether cleaning held
Day 60 — visual register check. Faster-than-expected dust return warrants follow-up
Day 90 — note musty odors, allergy changes, airflow inconsistencies. Early indicators for professional attention
In Altamonte Springs — year-round AC, persistent humidity, near-continuous pollen — the right filter strategy from move-in day isn't optional. It protects the investment you just made in starting clean.
For “Duct Cleaning Checklist for New Homeowners in Altamonte Springs FL,” the smartest first move is to treat duct cleaning as a verification process, not a guess: start by confirming what’s actually entering the system (dust, attic insulation fibers, pet dander, moisture residue), then pair any cleaning decision with a filter upgrade so you can measure the change afterward. A solid checklist starts with replacing the return filter immediately, then inspecting supply registers for visible buildup, checking for musty odor at startup, and confirming steady airflow room-to-room. That’s why products like 20x20x1 MERV 8 dust and allergy defense air filter and 12x24x1 MERV 8 pleated HVAC air filters 4-pack fit naturally into the process: a clean, correctly sized filter helps you see whether dust reappears quickly (often a sign of duct leakage or dirty returns) or slows down after cleaning. And for homeowners comparing options as they build their move-in maintenance baseline, 24x24x1 pleated HVAC replacement air filter is a quick reference point for pricing and availability while you decide whether a professional duct cleaning is warranted now or after you’ve verified the system’s condition.
Zero visibility into what the inherited duct system actually contains
Central Florida's humidity creates biological growth conditions for every year of previous occupancy
Near year-round AC operation — contamination compounds continuously with no recovery period
Previous pets, smokers, renovation activity — transfer invisibly at closing, filter changes won't resolve them
Documented professional cleaning within the last 2–3 years
No pets, smokers, or renovation history confirmed by seller
Newer construction with consistent MERV 8+ filter maintenance on record
Visual inspection shows no indicators at registers or air handler
Visible dust buildup on grille surfaces — filtration gaps or deferred maintenance
Dark staining around register edges — consistent indicator of particulate-carrying airflow over time
Visible debris inside duct opening — immediate red flag regardless of home age
Loose or missing register covers — unfiltered air entry point into the system
Filter condition — heavily loaded or degraded filter reveals previous owner's maintenance standard
Visible mold or biological growth at cabinet or evaporator coil
Dust on blower compartment — indicates how long system ran without professional attention
Moisture, rust, or water intrusion around the unit
Two or more indicators — schedule professional cleaning before move-in
Single indicator — professional inspection warranted before deciding
No indicators with documented history — cleaning may hold; monitor first 90 days
Year-round AC operation — approximately 11 months of continuous runtime. No seasonal shutdown. What takes five years in a seasonal climate develops closer to three here — sometimes faster.
Persistent humidity above biological growth thresholds — Seminole County exceeds 50% humidity for extended periods. Every year of previous occupancy is a year that the duct system operated in active mold and dust mite growth conditions.
Near-continuous pollen seasons — live oak, pine, and grass cycles overlap almost continuously. No defined start and end — the organic particulate buildup we find in local systems reflects it consistently.
National 3–5 year guidelines are a starting point — not a standard — in this market
Unknown duct history — apply the 3-year end of that range at minimum
Any occupancy risk factors push that timeline earlier — not later
