"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

DIY kits are available for basic air quality testing, but professional services provide more comprehensive results and recommendations. While a DIY kit may seem cost-effective, a professional assessment is more thorough. Inspectors are better equipped to catch all pollutants and hazards, and you'll still need a professional to verify and act on DIY test results. Furthermore, some kits don't test for certain pollutants or only detect their presence without measuring specific levels (like mold spores). It's generally better to opt for a detailed professional assessment.

Water and electricity are a dangerous duo, so you should always proceed with caution as you inspect your washing machine and attempt to fix or replace any parts. We recommend working with a trained professional when you have a big leak on your machine to avoid fire risks from short-circuiting and electrocution from live wires in your appliance.

Some mold can look like dust, but most doesn’t. Powdery mildew is often confused with dust as it’s a similar color and grows in a similar way. Some gray molds can look like dust as well, but usually, it’s pretty easy to spot the difference. It’s better to be safe, so if you aren’t completely sure what you’re seeing is dust, call a mold professional to check it out.

Powdery mildew tends to grow mostly on leafy plants. The mold itself isn’t particularly harmful, except for those who are allergic to mold. However, you should treat it like you’d treat the discovery of any other mold, and get rid of it immediately. Powdery mildew can spread to your home, which can cause expensive damage. 

Yes, air duct cleaning can remove mold from the interior lines of HVAC systems.

Keeping your air ducts clean can also help prevent the conditions that allow mold to grow and thrive in your ductwork.
