**Anchorage Asthma: AC Lies Hiding Deadly Mold?**
By Franklin Everett ShawThe crisp Alaskan air, while invigorating, can sometimes hide a silent threat within our homes: mold. Especially in Anchorage, where our homes are sealed tight against the long winters, condensation can become a breeding ground for unwanted fungal guests, particularly in our air conditioning units. But before you panic and call in the hazmat team, let’s explore how you, as an Anchorage resident, can assess the situation yourself.
This guide will equip you with the knowledge to identify potential mold contamination in your AC unit, understand the specific risks in our climate, and know when it’s time to call in the professionals. We’ll focus on DIY inspection techniques, local resources, and preventative measures to keep your air clean and your lungs happy.
First, let’s talk about why Anchorage AC units are particularly susceptible to mold. Our short, intense summers mean our ACs work hard and often get shut down abruptly in the fall. This sudden stop can leave moisture trapped inside, creating the perfect environment for mold growth during the long, dark winter months.
Now, let’s get practical. Before you start poking around, safety first! Turn off the power to your AC unit at the breaker box. This prevents any accidental shocks while you’re inspecting.
Your primary target is the evaporator coil, usually located inside the indoor unit. You’ll likely need a screwdriver to remove an access panel. Once open, use a flashlight to carefully examine the coil. Look for:
- Visible mold growth: This can appear as fuzzy, discolored patches (black, green, white, or brown).
- Musty or earthy odors: A strong, persistent smell is a telltale sign, even if you can’t see the mold.
- Excessive dust or debris: This provides a food source for mold.
Don’t forget to check the drain pan, located beneath the evaporator coil. This is where condensation collects, and it’s a prime spot for mold to flourish. Look for standing water, discoloration, or slimy buildup.
Another area to inspect is the air filter. While the filter is designed to trap dust and allergens, it can also become a breeding ground for mold if it’s not changed regularly. Hold the filter up to the light. If it’s visibly dirty or has any discoloration, it’s time for a replacement.
Now, let’s talk about the types of mold you might encounter. While a lab test is the only way to definitively identify the species, some common culprits in Alaskan AC systems include Cladosporium, Aspergillus, and Penicillium. These molds thrive in damp environments and can trigger allergic reactions, asthma symptoms, and other respiratory issues.
The health risks associated with mold exposure are particularly relevant in Anchorage. Our long winters already put a strain on our respiratory systems, and adding mold spores to the mix can exacerbate existing conditions. Symptoms can include:
- Coughing
- Wheezing
- Sneezing
- Runny nose
- Sore throat
- Skin rashes
- Eye irritation
If you experience any of these symptoms, especially if they worsen when your AC is running, it’s crucial to consult with a doctor.
So, you’ve inspected your AC unit and found some suspicious signs. What’s next? This is where you need to make a judgment call. If the mold growth is minor and contained to a small area, you might be able to tackle it yourself.
Here’s a DIY cleaning solution: Mix one part bleach with ten parts water. Always wear gloves, eye protection, and a mask when working with bleach. Use a soft brush to gently scrub the affected areas, then wipe them down with a clean, damp cloth. Ensure the area is thoroughly dry afterward.
However, there are situations where DIY cleaning is not recommended. If the mold growth is extensive, if you’re sensitive to mold, or if you’re unsure about the extent of the contamination, it’s best to call in a professional.
In Anchorage, several HVAC and mold remediation specialists can help. Companies like Polar Bear Services and Northern Comfort Heating & Air Conditioning offer AC cleaning and mold inspection services. For more extensive mold remediation, consider contacting companies like Alaska Premier Restoration or Dry Ice Blasting Alaska.
When choosing a professional, make sure they are licensed, insured, and experienced in dealing with mold in AC systems. Ask for references and read online reviews to get a sense of their reputation.
Now, let’s talk about prevention. The best way to deal with mold is to prevent it from growing in the first place. Here are some preventative measures you can take:
- Regularly change your air filter: Aim to replace it every 1-3 months, depending on usage and air quality.
- Schedule annual AC maintenance: A professional can clean the coils, drain pan, and other components, preventing mold growth.
- Keep the area around your AC unit clean and dry: Remove any clutter that could trap moisture.
- Consider using a dehumidifier: This can help reduce humidity levels in your home, making it less hospitable to mold.
- Run your AC fan periodically: Even when you don’t need cooling, running the fan can help circulate air and prevent moisture buildup.
A common mistake Anchorage residents make is neglecting their AC units during the winter months. Just because you’re not using the AC doesn’t mean it’s immune to mold growth. Taking preventative measures year-round is crucial.
Another pitfall is using harsh chemicals or abrasive cleaners on your AC unit. These can damage the components and create a breeding ground for mold. Stick to mild cleaning solutions and soft brushes.
Finally, don’t ignore musty odors. Even if you can’t see any visible mold, a persistent smell is a sign that something is amiss. Investigate the source of the odor and take action to eliminate it.
By following these tips, Anchorage residents can take control of their indoor air quality and protect themselves from the health risks associated with mold. Remember, a little prevention goes a long way in keeping your AC unit clean and your lungs happy. And when in doubt, don’t hesitate to call in the professionals. Your health is worth it.
