  • Mountain cedar fever
  • Tree pollen

The mountain cedar (ashe juniper) is an evergreen, drought-resistant tree that is one of the biggest causes of allergies in San Antonio. The infamous mountain cedar fever starts in late December and lasts until March, when the tree produces large amounts of pollen.

Contrary to its name, “cedar fever” doesn’t actually cause fevers, but rather allergy symptoms such as a sore throat, sneezing and watery eyes.

For more information about how to fight cedar fever, read our blog “Mountain Cedar Season: When It Begins, Ends and How to Survive It.”

Right when mountain cedar fever starts to die down in March, other trees start to pollinate, creating a fresh batch of allergies for San Antonio residents.

Some of the trees that produce pollen from March to May include:

  • Live oak
  • Hackberry
  • Arizona ash
  • Willow

When these trees pollinate (especially live oak), it’s not uncommon to see driveways, sidewalks and pets covered in tiny yellow pollen.

During the summer, grass flourishes in San Antonio. While it makes our lawns prettier, grass also produces pollen, which irritates a lot of people’s respiratory systems.

Grass allergies are provoked in the summer because people spend more time outdoors and mow the lawn more often, which kicks up the pollen in the air.

From October to November, weed pollen is prevalent in San Antonio—especially ragweed. Ragweed can grow as tall as a person and one single plant can release a billion grains of pollen per season.

Because of their prevalence and potency, ragweed is extremely aggravating to allergy sufferers.

With our humid climate and rainy seasons (summer and fall), mold allergies are common in San Antonio.

After heavy rainfall, it’s common to see a surge of mold-related allergies as mold spores are dispersed by the wind. Similar to the other allergens on the list, mold allergies cause similar symptoms such as coughing, a runny nose and itchy eyes.

After reading that long list of allergies, you may be wondering if there’s any relief. Luckily, today’s air quality technology can help you fight seasonal allergies.

Below are 3 ways you can improve the quality of your home’s air and reduce allergies:

  1. Check your air filter regularly: We recommend checking your air filter monthly and changing it when it’s dirty. This will not only remove more airborne allergens but also improve the efficiency of your HVAC system.
  2. Consider a whole-home dehumidifier: If you are battling mold allergies, a dehumidifier could help reduce the mold count in your home.
  3. Invest in a whole-home air purifier: A whole-home air purifier is a device that’s installed in your home’s HVAC system. Depending on the type of air purifier you get, it will either filter or kill allergy-inducing particles in your home’s air.

We can give you a free quote on the cost to install one in your San Antonio home. Visit our air quality service page to see other ways we can improve your indoor air quality.
