When homeowners think about humidity problems, basements and crawl spaces usually come to mind. But one of the most overlooked — and most critical — areas of the home is the attic. Because it sits between your living space and the roof, the attic plays a major role in moisture control, energy efficiency, and overall…
In Florida’s hot and humid climate, air conditioning systems work overtime to keep homes comfortable. But there’s a hidden issue many homeowners never see—until it becomes a costly problem. Moisture damage and mold growth beneath air handlers are far more common than most people realize, and uninsulated return boxes are often the root cause. Uninsulated…
Duct encapsulation is one of the most critical — and most misunderstood — steps in restoring indoor air quality after contamination has been identified inside an HVAC system. At Greenfox Air Quality, we treat duct encapsulation as a precision process, not a generic add-on. That’s why we exclusively use IAQ 8000 for both residential and…
Evaporator coils play a critical role in how an HVAC system functions, yet they are often one of the most overlooked components when it comes to routine maintenance. Over time, coils can accumulate dust, debris, moisture, and biological buildup, all of which can negatively affect system performance and indoor air quality. In humid environments like…
When people think about silica dust on construction sites, they usually think about worker safety. Respirators. Wet cutting. OSHA compliance. What almost no one thinks about is what happens after that dust goes airborne, and where it ends up. On many renovation and build-out projects, silica dust doesn’t just settle on floors or surfaces. It moves…
VA Loans, USAA, Coverage Limits, and the Fine Print Veterans Should Know Veterans often assume that a VA loan comes with special insurance protections for problems like mold. In reality, the VA loan program is a mortgage guaranty, and has property condition requirements, but it does not “include” mold coverage. That distinction matters. Mold is…
During professional mold remediation, containment barriers are installed to isolate affected areas and prevent contaminants from spreading to clean spaces. While most remediation teams focus on walls, doorways, and flooring, one critical detail is often overlooked: HVAC return plenums and return vents located inside or near the containment area. Failing to properly address returns can…
In South Florida, heat and humidity aren’t just outdoor inconveniences, they are powerful forces that affect how buildings function. One well-intentioned but often problematic design choice we see is enclosing HVAC air handlers located in attics with drywall or framed “boxes.” While these enclosures are usually built to “protect” the system or improve aesthetics, they…
Most homeowners don’t associate attic rodent activity with the air they breathe every day. While chewed wires or damaged insulation may raise concern, the less visible consequences, such as poor indoor air quality, often go unnoticed. In homes with attic-located HVAC systems, the attic is not a sealed-off space. It is connected to the living…
When people suspect mold, the typical next step is calling a mold assessor or indoor air quality professional. But there’s another tool that’s gaining traction: trained mold detection dogs. The idea can sound unusual at first, but the process is straightforward: the dog searches for the odor associated with mold, then humans use that information…
