Houston Heat: Leaky AC Crashing Baby Livers?

By Franklin Everett Shaw

January 24, 2026

It’s not just about the heat; it’s about what the heat leaves behind. Houston summers are brutal, and our AC units work overtime. But when they fail, the consequences can extend far beyond discomfort, especially for our little ones. We’re talking about hidden dangers lurking in the air, dangers that can impact the health of your family, particularly infants and young children.

This article is your guide to navigating these risks, specifically focusing on mold and chemical exposure from failing AC units in Houston homes. We’ll equip you with the knowledge and tools to identify potential problems, take proactive steps, and connect with local resources to ensure a healthy home environment for your family.

Understanding the Risks: Mold and Chemical Exposure

A failing AC unit creates the perfect breeding ground for mold. Condensation builds up, especially in Houston’s humid climate, leading to mold growth within the unit itself and potentially spreading through your ductwork. This isn’t just about unsightly spots; mold spores can trigger allergic reactions, asthma attacks, and other respiratory problems, particularly in infants and young children whose immune systems are still developing.

Beyond mold, chemical exposure is another concern. Refrigerant leaks, while less common, can release harmful chemicals into the air. Older AC units may contain refrigerants that are particularly hazardous. Even newer refrigerants, while generally safer, can still cause irritation and health problems if leaked in significant quantities.

DIY Testing Methods: Taking the First Step

While professional testing is recommended for accurate results, there are DIY methods you can use to assess potential risks.

Visual Inspection: Carefully inspect your AC unit and surrounding areas for visible mold growth. Look for dark spots, discoloration, or a musty odor. Pay close attention to the drain pan, coils, and ductwork. Remember to turn off the unit before inspecting it.
Mold Test Kits: Purchase a mold test kit from a local hardware store like Home Depot or Lowe’s. Follow the instructions carefully to collect samples from suspected areas. These kits typically involve sending the samples to a lab for analysis.
Air Quality Monitors: Consider investing in an air quality monitor that measures particulate matter (PM2.5 and PM10), volatile organic compounds (VOCs), and humidity. Elevated levels of these pollutants can indicate mold growth or chemical leaks.

Houston-Specific Resources for Professional Remediation

If your DIY tests indicate a problem, it’s crucial to seek professional help. Houston has numerous reputable mold remediation companies.

Texas Department of Licensing and Regulation (TDLR): Verify that any remediation company you hire is licensed by the TDLR. This ensures they meet certain standards and are qualified to perform mold remediation work.
Better Business Bureau (BBB): Check the company’s rating and reviews on the BBB website. This can provide valuable insights into their reputation and customer service.
Local Referrals: Ask friends, family, or neighbors for recommendations. Personal referrals can be a reliable way to find trustworthy professionals.

Protecting Infants and Young Children: Actionable Steps

Infants and young children are particularly vulnerable to the effects of mold and chemical exposure. Here’s how to protect them:

Air Purification: Invest in a high-quality air purifier with a HEPA filter. Ensure the filter is rated to capture mold spores and other airborne particles. Place the air purifier in your child’s bedroom or play area.
Regular AC Maintenance: Schedule regular maintenance for your AC unit to prevent problems before they arise. This includes cleaning the coils, changing the filters, and checking for leaks.
Proper Ventilation: Ensure your home is properly ventilated to reduce humidity levels. Open windows and doors when possible, and use exhaust fans in bathrooms and kitchens.
Prompt Remediation: If you suspect mold or chemical exposure, address the problem immediately. Don’t delay remediation, as the problem will only worsen over time.

Connecting Families with Houston-Based Pediatricians Specializing in Environmental Health

Finding a pediatrician with expertise in environmental health is crucial for addressing any health concerns related to mold or chemical exposure.

Texas Children’s Hospital: Texas Children’s Hospital has specialists in various fields, including environmental pediatrics. Contact their referral service to find a pediatrician with the necessary expertise.
Baylor College of Medicine: Baylor College of Medicine is another excellent resource for finding pediatricians specializing in environmental health. Their faculty includes experts in environmental toxicology and related fields.
Local Pediatric Associations: Contact the Harris County Medical Society or the Texas Pediatric Society for referrals to pediatricians with expertise in environmental health.

Liver Health Support: A Critical Consideration

Exposure to mold and chemicals can put a strain on the liver, the body’s primary detoxification organ. Supporting liver health is essential, especially for young children.

Diet: Encourage a diet rich in fruits, vegetables, and whole grains. These foods provide essential nutrients that support liver function.
Hydration: Ensure your child stays well-hydrated by drinking plenty of water. Water helps flush toxins from the body.
Probiotics: Consider giving your child a probiotic supplement to support gut health. A healthy gut can help reduce the burden on the liver.
Consult a Healthcare Professional: Talk to your pediatrician about specific supplements or dietary changes that may benefit your child’s liver health.

Specific Challenges and Pitfalls

Ignoring Musty Odors: A musty odor is often the first sign of mold growth. Don’t ignore it! Investigate the source of the odor and take action immediately.
Improper Cleaning: Attempting to clean mold yourself without proper equipment and precautions can actually worsen the problem. Mold spores can become airborne and spread to other areas of your home.
Using Bleach: Bleach is not an effective solution for killing mold on porous surfaces like drywall or wood. It only removes the surface mold, leaving the roots intact.
Hiring Unlicensed Contractors: Hiring an unlicensed contractor can be risky. They may not have the necessary training or experience to properly remediate mold or handle hazardous chemicals.
Delaying Remediation: Delaying remediation can lead to more extensive mold growth and higher remediation costs. It can also increase the risk of health problems for your family.

Real-World Scenario: The Heights Family

The Miller family in the Heights neighborhood of Houston experienced a similar situation. Their AC unit failed during a heat wave, leading to mold growth in their ductwork. Their infant son developed a persistent cough and respiratory problems. After consulting with a pediatrician specializing in environmental health, they hired a licensed mold remediation company to address the problem. They also installed an air purifier in their son’s bedroom and made dietary changes to support his liver health. Within a few weeks, his symptoms improved significantly.
