"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

Mold Testing and Remediation FAQs, answered by experts

Yes, brown spots on a ceiling are usually caused by water leaks and can lead to mold growth, especially if you don’t correct the underlying problem. Ongoing water leaks and moisture issues will almost always result in mold growth, especially if you live in a warm climate. Mold is a health hazard, so get the root problem fixed quickly, clean it, and encapsulate the area to avoid mold formation.

Neglecting mold growth on wood can result in various issues that deteriorate its appearance and jeopardize its structural stability. The mold's ability to multiply and expand can disintegrate the fibers of the wood, weakening it further. In addition, the allergenic spores and mycotoxins released by mold can pose health hazards through inhalation or contact. Ignoring the mold's presence allows it to thrive, increasing the likelihood of spreading to other surfaces and requiring extensive and expensive measures to control in the future. Addressing mold on wood promptly is crucial to preserving its condition and safeguarding the health of those around it.

No—there are key things that help you determine if it’s mold versus mildew. Mildew is a specific type of mold. Both can trigger allergies, asthma, and respiratory symptoms, though mold is typically more severe than mildew.

Mold thrives in wet and humid conditions, and the bathroom can often be an ideal place for it to grow. If you are worried about mold, it's a good idea to hire a local mold inspector to inspect your bathroom. 

How you handle the mold depends on the extent of the issue. If it's on the caulk or other surface, a deep cleaning with mold-killing products such as vinegar or bleach may be sufficient. For a large infestation, you'll most likely need professional mold remediation.

When you smell something, it’s because the particles of what you are smelling are floating through the air. If you smell mold, it means that it’s airborne, and whether or not it’s harmful depends on the type of mold. It’s very hard to tell the difference between molds, even with the internet to guide you. Call a professional as soon as you see mold, they will test it, remove it, and make sure you aren’t breathing anything harmful.
