"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, both mold and mildew can grow under outdoor rugs if they are exposed to water or humidity for a prolonged period of time. This is why frequently cleaning an outdoor rug and checking its state is important.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

Black mold on wood is a very serious issue. Besides compromising the structural integrity of the wood, it poses significant health risks. Stachybotrys chartarum, commonly known as toxic black mold, produces mycotoxins that can lead to respiratory issues, allergies, skin irritations, and other health problems. If left untreated, it can spread rapidly and compromise the structural stability of the affected wooden structures. Immediate remediation and preventive measures are essential to mitigate the risks associated with black mold on wood.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

No. When dry, mold enters a dormant state. While “sleeping,” the mold won’t multiply, but when it encounters moisture again, it springs back to life, releasing spores. That's why it's crucial to not only control humidity but also actively eliminate mold to prevent its resurgence and further growth inside your home.
