Albuquerque Air: Is Summer AC Hiding Deadly Mold?

Don’t let mold turn your Albuquerque dream home into a nightmare. It’s more common than you think, especially in our older adobe homes and with the fluctuating humidity we experience. This isn’t just about aesthetics; it’s about your health and the value of your property.

Here’s your comprehensive guide to tackling mold in your Albuquerque AC unit, from DIY testing to finding the right local pros.

First, let’s talk about why Albuquerque is a prime location for mold growth. Our climate, while generally dry, experiences monsoon seasons and sudden temperature shifts. This creates condensation, especially within the cool confines of your AC unit. Older homes, prevalent in areas like the North Valley and Old Town, often have less effective insulation and ventilation, exacerbating the problem. Add in the common use of porous building materials like adobe, and you’ve got a recipe for mold.

Step 1: Identifying the Problem

Don’t just assume you have mold. Look for the telltale signs. A musty odor emanating from your vents is a major red flag. Visually inspect the area around your AC unit, both inside and out. Look for discoloration, staining, or visible mold growth, which can range from white and powdery to black and slimy. Common spots include the drip pan, coils, and air ducts.

DIY Mold Testing (Proceed with Caution)

While professional testing is always recommended, you can start with a DIY mold test kit. These are available at most hardware stores in Albuquerque, like Lowe’s on Coors Blvd or Home Depot on Eubank Blvd.

Surface Testing: Use a swab to collect a sample from the suspected mold growth. Follow the kit’s instructions for sending the sample to a lab for analysis.
Air Testing: These kits collect air samples to determine the concentration of mold spores in the air. This can help identify hidden mold problems.

Important Considerations for DIY Testing:

Accuracy: DIY tests are not as accurate as professional testing. They can give you a general idea of whether mold is present, but they may not identify the specific type of mold or the extent of the problem.
Safety: Always wear gloves and a mask when handling mold. Avoid disturbing the mold too much, as this can release spores into the air.
False Negatives: A negative DIY test doesn’t necessarily mean there’s no mold. It could mean the sample wasn’t collected properly or the mold is hidden.

Step 2: Understanding the Health Risks

Mold exposure can cause a range of health problems, especially for individuals with allergies, asthma, or weakened immune systems. Common symptoms include:

Respiratory problems (coughing, wheezing, shortness of breath)
Skin irritation (rashes, hives)
Eye irritation (redness, itching)
Headaches
Fatigue

Children and the elderly are particularly vulnerable to the effects of mold exposure. If you suspect mold is affecting your health, consult a doctor. Presbyterian Healthcare Services and UNM Hospital are reliable resources in Albuquerque.

Step 3: Remediation - DIY vs. Professional

If the mold growth is small (less than 10 square feet) and contained to a non-porous surface, you might be able to handle it yourself. However, for larger infestations or mold in porous materials like drywall or adobe, professional remediation is essential.

DIY Remediation (Small Areas Only):

Safety First: Wear gloves, a mask (N-95 or higher), and eye protection.
Containment: Seal off the affected area with plastic sheeting to prevent the spread of spores.
Cleaning: Use a mold-killing solution (available at local hardware stores) and scrub the affected area thoroughly.
Drying: Dry the area completely with a fan or dehumidifier.
Disposal: Dispose of contaminated materials in sealed plastic bags.

Why Professional Remediation is Often Necessary:

Hidden Mold: Mold often grows in hidden areas, such as behind walls or under floors. Professionals have the equipment and expertise to find and remove it.
Proper Containment: Professionals use specialized equipment to contain the mold and prevent it from spreading during the remediation process.
Safe Removal: Professionals are trained to remove mold safely and effectively, minimizing the risk of exposure.
Prevention: Professionals can identify the source of the moisture problem and recommend solutions to prevent future mold growth.

Step 4: Finding Local Albuquerque Resources

Albuquerque has several reputable mold inspection and remediation companies. Here are a few to consider:

Duke City Remediation: Specializes in mold and water damage restoration.
Advantage Restoration: Offers comprehensive mold remediation services.
New Mexico Environmental Services: Provides mold inspection and testing services.

Directory of Certified Mold Remediation Specialists in Albuquerque:

Check the New Mexico Regulation and Licensing Department website for licensed contractors.
Verify certifications with organizations like the Institute of Inspection, Cleaning and Restoration Certification (IICRC).

Step 5: Preventative Maintenance - Key to Long-Term Solutions

Prevention is always better than cure. Here are some tips to prevent mold growth in your AC unit:

Regular AC Maintenance: Schedule annual AC maintenance with a qualified technician. They can clean the coils, check the drainage system, and identify potential problems.
Change Air Filters Regularly: Replace your air filters every 1-3 months, or more often if you have pets or allergies. This helps to remove dust and debris that can contribute to mold growth.
Control Humidity: Use a dehumidifier to keep the humidity level in your home below 50%. This is especially important during the monsoon season.
Improve Ventilation: Ensure adequate ventilation in your home, especially in bathrooms and kitchens. Use exhaust fans when showering or cooking.
Address Leaks Promptly: Repair any leaks in your roof, plumbing, or AC system immediately. Water damage is a major cause of mold growth.
Consider UV Lights: Install UV lights in your AC system to kill mold spores.

Step 6: Albuquerque Laws and Regulations Regarding Mold Disclosure

New Mexico law requires sellers to disclose any known material defects in their property, including mold. Failure to disclose mold can result in legal action. If you’re buying or selling a home in Albuquerque, it’s important to be aware of these regulations. Consult with a real estate attorney for more information.

Specific Challenges in Albuquerque:

Adobe Homes: Adobe is a porous material that can easily absorb moisture, making it susceptible to mold growth. Special care is needed when remediating mold in adobe homes.
Hard Water: Albuquerque’s hard water can contribute to mineral buildup in AC units, creating a breeding ground for mold.
Dust Storms: Dust storms can introduce mold spores into your home. Regularly clean your home and change your air filters to minimize the impact.

Common Mistakes to Avoid:

Ignoring the Problem: Mold problems don’t go away on their own. The longer you wait, the worse the problem will become.
Using Bleach: Bleach is not effective at killing mold on porous surfaces. It only removes the surface stain.
Not Addressing the Source of Moisture: If you don’t fix the underlying moisture problem, the mold will keep coming back.
Hiring an Unqualified Contractor: Make sure the contractor you hire is licensed and certified. Check their references and read online reviews.

By following these steps, Albuquerque homeowners can effectively identify, remediate, and prevent mold growth in their AC units, protecting their health and their investment. Don’t let mold take hold; take action today!
