If you live in Austin, you know cedar fever. Every winter the mountain cedar trees release clouds of pollen that leave people sneezing and worn out. That pollen does not stay outside. It rides indoors and settles in your supply ducts, where your system can push it back into the air you breathe. Here is what Austin homeowners should know.
What Cedar Fever Is
Cedar fever comes from the pollen of the Ashe juniper, which most people here call mountain cedar. These trees cover the Hill Country west and south of Austin, and they make up a large share of the trees in the area. When they release pollen, the count can climb very high.
The season usually starts in late November, peaks in December and January, and fades by late February. Symptoms include heavy congestion, sneezing, itchy eyes, a sore throat, and deep fatigue. The pollen is so thick that even people who do not usually react can feel it.
How Pollen Gets Into Your Ducts
Pollen drifts in on shoes, clothes, pets, and open doors. Once it is inside, your heating and cooling system pulls air through the home and some of that fine dust and pollen settles inside the supply ducts. The next time the system runs, it can carry those particles back out into your rooms.
Homes in cedar heavy areas like Westlake, Dripping Springs, Cedar Park, and Lakeway tend to see the most of it, but the pollen travels across the whole metro, from Round Rock to Buda.
What Duct Cleaning Can and Cannot Do
Cleaning your supply ducts removes the dust and settled pollen that has collected inside them. That means the system has less to recirculate when it runs. It is an honest help, not a cure. Duct cleaning will not stop pollen from coming in the door, and it does not replace allergy care from your doctor.
For the most benefit, pair a cleaning with these simple steps:
- Change your air filter often during cedar season, and use a filter rated for fine particles.
- Keep windows closed on high pollen days.
- Wipe down surfaces and vacuum with a sealed filter vacuum.
- Leave shoes at the door so less pollen tracks through the house.
The Right Time to Clean in Austin
Cedar season arrives with the cold months, so the smart move is to clean before it starts. Late summer and early fall are a good window. You go into November with clean ducts, so when the pollen climbs, your system is not holding a season of buildup.
Austin also has other allergy seasons through the year. Oak pollen is heavy in spring, ragweed shows up in fall, and our humidity can feed mold. Clean ducts help with all of them, not just cedar.
