"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

Vermiculite insulation that comes from a particular mine before 1990 is likely to contain asbestos. This is particularly true in the U.S. However, not all types of vermiculite insulation contain asbestos. Since you can't detect the presence of asbestos without special equipment, it's best to assume that the insulation contains the dangerous mineral and to either leave it alone or hire a professional to handle it.

Once again, contact with moisture is the culprit here, though water-resistant varieties of wallpaper are less likely to become wet and develop mold. Using a high-quality exhaust fan or dehumidifier and leaving the doors or windows cracked after bathing will keep this issue at bay. 

Although fiberglass dust is generally not considered toxic, inhaling excessive amounts of it can lead to health risks. Irritation to the respiratory system, eyes, and skin are common effects of fiberglass particle inhalation. While short-term exposure to the dust may only cause temporary discomfort, long-term or chronic exposure can lead to more severe respiratory problems.

Proper safety measures, such as wearing appropriate protective equipment, including masks and goggles, should be observed when handling or working with fiberglass materials to minimize health risks. It is important to note that, unlike asbestos, fiberglass is not associated with life-threatening illnesses.

Removing mold yourself can be dangerous. Always wear protective gear to cover your skin, face, and eyes, and wear a respiratory mask to protect your lungs. It is most recommended to only remove small areas of mold on your own and leave large mold growth to professionals. Mold growth can also be persistent. Without addressing the root cause, DIY surface cleaning can be ineffective and temporary.

Mold can grow quickly in wet carpet: in as little as 12 to 24 hours. That’s why it is crucial to take action immediately if there’s any sign of water damage under your floor. Remove as much water as possible with a shop vac and towels, then use baking soda to help remove moisture deep in the fibers. Always steam clean the carpet or use an antibacterial carpet sanitizer to kill any mold growth.
