Prevent Black Mold and Minimize Mold Growth

If you read our last post, you are aware that black mold can make you sick.  So what can you do to prevent mold and minimize mold growth? Castellano Air Condition Services has some tips to help keep your indoor air quality optimal.

Preventing Mold

■ Consider air conditioning possible augmented with a dehumidification system. These systems pull the moisture from the building thus minimizing growth by depriving mold of one of its nutrients. 

■ Use caution when you turning your air conditioning off. In humid climates, extended periods of non-operation of HVAC equipment may allow humidity levels to become quite high in buildings.
These periods can permit mold to gain a foothold in the building and thrive.

■ Install insulation and vapor barriers to prevent condensation on cold objects such as water pipes, beams, and plumbing fixtures.

■ Keep sinks, showers, tubs and other “wet” areas free of standing water. 

■ Demand architectural, design, and construction applications that prevent water from entering the interior. Areas of concern include improperly pitched roofs, poorly designed balconies, windows,
doors, improperly installed flashing, vapor barriers, and thin stucco.

■ Maintain the integrity of building envelope through regular inspections, caulking, roof flashing, and sealing of the buildings exterior.

■ Perform semi-annual maintenance of HVAC mechanical systems using Preventative Maintenance Agreements with your ACCA Contractor. If water pooling or dust and dirt are allowed to accumulate in a system, the HVAC system could support mold growth.

■ Inform your HVAC contractor of your mold concerns and point out locations of suspicion or evidence of mold. 

■ Educate you family or building occupants about mold, the dangers, and prevention.

How can I minimize mold growth?

Mold is a natural byproduct of the fungi family that thrive when nutrients—primarily organic substances and water—are found in the right conditions. These organic substances include materials commonly found in buildings: soil, dead plants, carpets, drywall, fiberboard, wood, paper, dust, lint, and etc.  Mold propagates via spores that can remain dormant—yet viable—for years during periods when moisture is not present. Mold issues require education, identification, remediation, and solutions to minimize mold growth in the environments we live.

Heating Ventilation and Air Conditioning (HVAC) mechanical systems are not generators of mold. Their metallic surfaces do not provide the organic matter mold needs to grow. However, systems that are not well maintained could support mold growth.

Good Mold vs Bad Mold

Mold is everywhere and can have many benefits.  However, it can also lead to poor indoor air quality and even sickness. 

Good Mold

Molds are the “bleu” in bleu cheese and Roquefort. Molds improve our wine. They produce penicillin and antibiotics and are used widely in the food and beverage industry. Without mold and mold’s decaying mechanism, the natural environment would be overwhelmed with large amounts of dead organic matter.

Bad Mold

Despite many harmless and beneficial molds, some molds can be toxic and pose very serious health threats to humans. The Environmental Protective Agency (EPA) cautions that all molds can cause health problems under the right conditions. The word “toxic” is used to refer to mold that produces toxic compounds, or mycotoxins.  Often included in the list of toxic molds is Stachybotrys Chartarum, a greenish-black mold, which can grow on high cellulose, low nitrogen materials such as fiberboard, drywall, paper, dust and lint in the presence of moisture.

4 Tips to Keep Your Tampa HVAC System Running Smoothly All Year Round

Last week, we spoke about the importance of having your heating, air conditioning, and ventilation
(HVAC) system checked twice a year for safety and comfort.  Today, Castellano AC Services would like to present you with some tips on what you can do to keep your HVAC system humming in between regular maintenance visits.

Tip 1: When you cut grass near the outdoor condensing unit, make sure grass cuttings are blown away from the outdoor coil.

Tip 2: Cut, pull, or trim shrubs, bushes, plants, and weeds around the condenser to allow a free air flow.

Tip 3: Keep the area around the condensing unit cleared of leaves, dirt, grass cuttings, and other debris that can cause clogs and restrict the flow of air.

Tip 4: Be sure not to build fences, walls, or other obstructions too close to the unit or cover
it with a roof  or overhang.

One Last Idea from your Tampa HVAC Experts

In addition to following these four tips, the easiest way to stay cool in summer...and warm in winter...
is to have a Planned Maintenance Extended Care Plan with Castellano AC Services.

Mold in a Home or Building

Last week, we briefly discussed what mold is and how toxic mold can impair your indoor air quality and adversely affect your health.  Today, we will go over what you should do if you suspect you have mold in your home or building.

The first step is to alert your HVAC contractor and/or the building contractor (if the building is relatively new) regarding your concerns. The next step is education and exploring solutions. If mold is found, identifying the type will help establish whether any dangers are present. If health issues are present, evacuation, abatement, and remediation are necessary.  The identification of mold requires specialized testing and laboratory analysis to determine the type of mold and any of the health hazards that may be associated with it.  If your HVAC contractor does not perform mold analysis, abatement, and remediation, they may be able to identify a partnering company that is a trained and certified in this type of work.
