The Connection Between Mold & HVAC Systems, New York, New York

As spring arrives, the likelihood of mold developing in your home increases, and HVAC systems are one of the most common causes. Mold poses a serious health risk to your family’s health, which is why you need to understand its causes and possible solutions. Below you’ll find a quick guide on the connection between HVAC systems and mold.

How HVAC Systems Cause Mold Growth

hvac-system-cottam-heating-and-air-contioningMold requires warmth and moisture to grow, which means that HVAC ductwork is an ideal environment. As cold air passes through, it will leave water droplets if the temperature outside is humid, such as in spring. Once the moisture settles, mold can form. It feeds on dust, pollen, and animal dander circulating in your HVAC system. Mold spores produce a musty smell that will travel throughout your home and create problematic side effects. These include sinus, throat, and eye irritation, as well as random headaches, fatigue, dizziness, and nausea. Mold exposure can be fatal in people with severe allergies, respiratory complications, and weakened immune systems.

Preventing Mold Growth

To prevent mold growth, change your HVAC filters regularly and insulate your ductwork. You should also seal your ductwork and have a professional check it regularly for problems or signs of mold growth. If you have an older system, consider upgrading. You can choose a ductless AC option to eliminate the possibility of mold growing in ductwork or choose a high-efficiency model that will reduce moisture. You’ll enjoy added benefits from the investment, including superior heating and cooling, seamless control, and increased monthly savings.
