Mold Remediation | Indoor Air Quality Kennett Square, PAThe majority of modern humans spend an inordinate amount of time indoors, making indoor air quality of the highest importance. Live organisms typically take the form of Mold & Bacteria. As such, we should all be concerned with what is in the air we are breathing. Children and the elderly are especially susceptible to adverse reactions to pollutants in the air. Contact with these substances can cause sore eyes, burning in the nose/throat and headaches, as well as more severe effects such as respiratory illness, heart disease, cancer or other long term conditions.

How Did I Get Mold In My Home?

Molds are part of the natural environment and can begin reproducing quite easily. All it takes is for some spores to land on a wet surface and it will begin replicating. Mold can enter through many different passages such as your doorways, vents, windows and central air systems. Mold can even be tracked in from outside when it attaches itself to clothing, bags, or even pets. The mold tends to grow and thrive in places with an abundance of moisture such as leaky roofs and windows, or where there may have been some flooding.

How Serious Of A Problem Is The Mold Potentially?

Some mold is totally harmless – like *cosmetic* black mold or Ophistomoid fungi. These harmless black molds are often found on framing lumber and sometimes plywood. However, Stachybotrys Atra is a toxic mold and notorious mycotoxin producer. Some symptoms of exposure to toxic black mold include dermatitis, sinusitis, conjunctivitis.

This mold tends to grow on soaked wood, wall panels, cotton, cardboard and stacks of newspapers. Aspergillus is another mold that is very harmful, known to cause disease in humans and animals. Aspergillus is commonly found in house dust or areas of water damage / extreme dampness. Whether you have mold that is relatively harmless or a serious health concern, it all does one thing which is lead to more mold breeding so your situation can always get worse. It’s best to handle any signs of mold as soon as you uncover them.

What To Do When Mold Is Uncovered

The key to mold control is having control over moisture and humidity levels within your home. There’s no practical way to eliminate all mold spores, so the way to control it is to control moisture. Upon finding a mold issue, you must immediately eliminate the source of moisture. If there’s a leak or flooding, the first step is to resolve those issues. Next, reduce indoor humidity so that it rests at a level between 30-60%. Ways you can reduce the humidity are venting bathrooms, using air conditioning systems / de-humidifiers, and using exhaust fans whenever cooking, dishwashing, and cleaning.

Hiring A PRO to Assess Your Mold Issue

You can hire a professional if you’re concerned about properly taking care of the mold. Besides properly identifying the type of mold and extent of infestation, a PRO can offer you installations of air-purifiers, dehumidifiers and more.

Coming home to a cold house on a chilly Pennsylvania day can be a stressful and aggravating experience. While many tasks involving HVAC equipment should be handled by licensed professionals, there are a few easy troubleshooting methods that could save you some time and frustration.

If your heater isn’t turning on

Make sure Your Thermostat is set to Heat

Yes, it sounds obvious, but if you’re not looking for the small stuff like this, it can be easy to overlook. It’s easy enough for someone to accidentally set the thermostat to the wrong setting without noticing.

Check Your Filters


Dirty and clogged filters can sneak up on you, especially if you haven’t been paying attention to regular furnace maintenance. Dirty filters not only cost you money in the form of lost efficiency, they can also lead newer equipment to shutting down altogether. If you can find your filter, pull it out and replace it if it’s clogged with debris. The new component will not only get your system running again, but will improve its efficiency and help remove irritants from the air.

Make Sure You’ve Got Power

Check your thermostat to make sure it’s on. If it isn’t you may need to replace its batteries or trip the breaker to get the unit up and running again. Similarly, check your circuit breaker to make sure your heating equipment is getting electricity. Even gas systems still often need a power supply for their sensors and fans.

One last place to check for power is the furnace switch – this is a separate switch located on or near the furnace that controls power to the equipment. Make sure this has not been switched to off.

Anything beyond these basic troubleshooting steps may require some more in-depth knowledge of your home’s gas systems and your furnace’s particular configuration. If you’re comfortable working with this kind of equipment, you can find how to light your pilot light (For older furnaces) or find model-specific troubleshooting guides in your furnace’s owner’s manual. Always remember, working with this equipment can be dangerous, and HVAC technicians go through extensive training to be able to work on and repair these essential home systems.
