Indoor Air Quality and Home Performance 
Services in Brookhaven

When the average homeowner hears the term "indoor air quality," they tend to think about the temperature of their home, and maybe even the humidity levels. These are important factors of course, but not a total assessment of your home performance. Quality home performance means having a living space that has healthy, breathable air. You want to look beyond the HVAC air filter and consider your whole-house air filtration and purification options, in addition to heat and energy recovery.

$129 Duct Fogging!

Air Quality Improvement: The fogging solution helps eliminate mold, mildew, bacteria, and other contaminants that can accumulate inside the ducts over time. This helps to improve the quality of the air that circulates through the HVAC system and, ultimately, the indoor air quality of the building.

Odor Elimination: Duct fogging can be used to neutralize unpleasant odors caused by mold, mildew, pet dander, cooking, or other sources that may be trapped within the ductwork.

Disinfection and Sanitization: By using appropriate disinfectants or antimicrobial agents, duct fogging can help reduce the spread of germs and bacteria within the HVAC system, contributing to a healthier environment.

UV Blue Tube & Dirty Sock Cleaning Spray for $1150!

A condition that occurs in HVAC systems where the system emits a foul, musty odor similar to that of dirty socks. This can be caused by a buildup of bacteria, mold, and other contaminants in the system's evaporator coil and drain pan.
Ways to prevent Dirty Sock Syndrome: Clean the evaporator coil, install a UV Blue Tube and have regular maintenance performed on your HVAC system.
