Mold Testing and Remediation questions, answered by experts

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

Homes should be checked for mold annually, especially if you live in an area with high humidity or frequent rainfall. Inspections are crucial following flooding, roof leaks, or plumbing issues. More frequent checks are necessary if your home has a history of mold problems or water damage. Regular inspections help detect mold early, preventing costly remediation and minimizing health risks, especially in moisture-prone areas such as basements and bathrooms.

Many types of mold spores and fungi spores are constantly present in the air, but they need a friendly surface and moisture to grow. Should some of these spores land on paper or wood with significant moisture present—such as drywall with a paper cover that is soaking up water from a leak—mold or fungi could begin growing. Dampness from leaky pipes, condensation on windows, leaks in a roof, flooding in a basement, or high, prolonged humidity in a small area all can create the excess moisture that mold and fungi need to grow in your home.

The most common sign of a carbon monoxide leak is the visible black soot marks on the walls near your wood stove. An excess accumulation of smoke in other rooms of your home could also indicate that your wood burning stove is leaking carbon monoxide. If you notice either of these signs or are still unsure, it’s best to leave the premises and contact your fire department to check your home’s levels.

If you have mold under your vinyl flooring, it’s recommended that you have it ripped out and start fresh. Mold isn’t something to take lightly and should involve a visit from a professional who can both test and identify the mold. If you’re determined to remedy it yourself, wear all the proper protective equipment—eye goggles, a high N-rated mask, and long, disposable gloves.
