Congratulations — you got the keys. Somewhere between the movers and the cable install, add one more appointment to the list, because your new home's air ducts are carrying the previous owners' history: their dust, their pets' dander, their cooking, their renovation debris. You can't see it, but you'll breathe it every day until it's cleaned.
You're breathing the previous owners' air
Ducts are a home's memory. Everything that lived in the air — pet hair and dander, cigarette or cigar smoke residue, years of dust, pollen tracked in from the yard — settles into the ductwork and stays there, recirculating a little at a time. Sellers vacuum, mop, and paint before listing. Nobody cleans the ducts. If the previous owners had pets you don't, smoke you can't stand, or hygiene you wouldn't choose, a duct cleaning is how you actually start fresh.
What your home inspection didn't check
A standard home inspection confirms the AC turns on and cools. It does not put a camera inside the ductwork, and it doesn't grade what's living in there. We regularly open ducts in 'inspected and passed' homes and find construction debris from a decade-old remodel, heavy microbial growth, and vent runs half-blocked with accumulated dust. The inspection is still essential — it just isn't an air quality check. That part is on you.
The pre-listing renovation problem
Sellers fix up before they sell: fresh paint, new floors, a patched ceiling, a quick kitchen refresh. Every one of those jobs makes dust, and if the AC ran during the work — it usually did — that dust went straight into the returns and settled through the system. The house looks brand new. The ducts are carrying the renovation. A cleaning after closing clears out the one part of the flip nobody touched.
Timing: the empty-house window is gold
The single best moment to clean ducts is between closing and move-in day, while the house is empty. No furniture to work around, no vents blocked by boxes and beds, and the crew can move fast — an empty home is often quicker to clean than a furnished one. If that window has passed, don't worry: we clean furnished homes every day and protect everything. But if you're reading this before the movers come, book the cleaning first.
And if the AC itself has a problem?
Unknown maintenance history cuts both ways — sometimes the inspection finds ducts that are fine and an AC that's struggling: a coil caked from years without service, a drain line about to clog, a blower wearing out. When that happens during one of our inspections, we show you exactly what we found. Because Fair Air also does AC repair, we can quote any needed repair on the spot, in writing — and cleaning and repair can often be handled in the same visit, before you move in.
A simple move-in air checklist
- Book a duct inspection/cleaning for the empty-house window if you can
- Replace the AC filter on day one — and write the size on the calendar for monthly checks
- Ask the sellers (through your agent) when the AC was last serviced and the ducts last cleaned — most can't answer, which is your answer
- Run every system zone by zone in the first week and note weak airflow or musty smells room by room
- Check the dryer vent too — it's the other forgotten airway in a new-to-you home, and a genuine fire risk when clogged

Frequently asked questions
Should I get the ducts cleaned before or after moving in?
Before, if you can. The window between closing and move-in — while the house is empty — is ideal: no furniture blocks the vents, and the crew can work faster. If you've already moved in, we clean furnished homes every day and protect your floors and furniture.
Doesn't the home inspection cover the AC and ducts?
A home inspection confirms the AC runs and cools. It does not put a camera inside the ductwork or evaluate what's accumulated in it. We regularly find construction debris, heavy dust, and microbial growth in homes that passed inspection — the ducts are simply outside its scope.
The previous owners had pets. Does that matter?
Yes. Pet dander and hair settle deep into ductwork and keep recirculating long after the pets are gone — a real problem if anyone in your family has allergies. A professional cleaning removes the previous owners' pet history from the system. The same applies to smoke residue.
How soon after closing should I book?
As soon as you have keys and access. Duct cleaning works best before furniture arrives, and in South Florida the AC will be running from day one — you want it pushing air through clean ducts from your first night in the home.
What if the inspection finds a problem with the AC itself?
We'll show you exactly what we found — a caked coil, a clogging drain line, a worn blower. Because Fair Air also does AC repair, we can give you an exact written quote for the repair on the spot, with no obligation. Cleaning and repair can often be handled in the same visit.
