"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

Mold loves a moist environment, so the best way to keep it from returning is to keep your machine as dry as possible. Take laundry out of the machine as soon as you can after a cycle finishes. If your laundry room is humid, consider using a dehumidifier or at least running a fan to increase airflow.

It's also a good idea to leave the washing machine door open when it's not in use, to improve airflow and keep the interior dry.

If you're wondering about black stains on brick at your home, the answer is that you're not looking at efflorescence. While efflorescence can be darker when certain types of salt are involved, black staining is caused by carbon staining, pollution from vehicles, and chimney soot. Black stains can also be caused by organic materials like lichen, algae, or mold.

Most grass mold isn’t harmful to humans. Slime molds in particular aren’t toxic and may even possess some benefits. Other molds, like powdery mildew and snow mold, generally aren’t a concern, but can still cause allergic reactions and respiratory distress in those with high allergy risk and compromised immune systems.  

You normally won’t see any dust or mold actively floating out of your vent, but you might notice your vent looks dirty. Mold will cling to the sides and collect almost like black soot. Dust will look, well, dusty, but there will usually be a heavy buildup so expect thick gray layers on the bottom and sometimes the sides of the vent. If you suspect you have mold in your vents, call a professional immediately.

It is safe to remove old linoleum, but it may require the help of a specialist due to the risk of asbestos in the material. Before you cut into linoleum or try to peel it up, have it tested for asbestos. If it tests positive, professionals will need to remove it to prevent the risk of health issues from airborne toxic particles. If it’s asbestos-free, DIY removal is possible and safe.
