HOME / INDOOR AIR QUALITY
Indoor air quality work should begin by identifying whether the problem is excess humidity, airborne particles, odors, microbial growth near wet HVAC surfaces, inadequate ventilation, duct leakage, or poor airflow. Blast Mechanical evaluates the home and existing HVAC system before recommending compatible equipment or corrections.
Gulf Coast homes have long cooling seasons and high outdoor moisture loads. Oversized cooling equipment, short run times, duct leakage, drainage problems, infiltration, and inadequate ventilation can leave a home cool but humid. Filtration and humidity control solve different problems, so one product should not be presented as a cure-all.
Depending on the diagnosis and system compatibility, options may include a properly sized pleated media filter, whole-home dehumidifier, ventilation correction, duct sealing or airflow correction, condensate management, or UV-C treatment directed at the indoor coil and drain-pan area. Filter efficiency must be balanced with available airflow and static pressure. UV-C can help control microbial growth on irradiated HVAC surfaces, but it does not replace filtration, moisture control, or source removal.
The appropriate category depends on the measured or observed problem. Common options include media filtration, whole-home dehumidification, duct or airflow correction, ventilation improvements, condensate management, and UV-C treatment at wet HVAC surfaces. Specific brands and models are selected only after checking system compatibility.
Often, yes. Available duct space, electrical requirements, drainage, airflow, static pressure, equipment layout, controls, and manufacturer instructions determine what can be integrated safely and effectively.
A more efficient filter can capture smaller particles, but the filter cabinet and blower must be able to move the required airflow without excessive pressure drop. The best filter is one that improves particle capture while remaining compatible with the system.
A common comfort target is roughly 30% to 50% relative humidity, although the practical setting depends on outdoor conditions, the home, and occupant comfort. Persistent readings above that range deserve an evaluation of moisture sources, infiltration, HVAC sizing, airflow, drainage, and dehumidification.
