Why IAQ Matters
Indoor air quality has become a major concern for homeowners. HVAC contractors are well-positioned to offer IAQ solutions:
- EPA rates indoor air pollution among top environmental health risks
- People spend 90% of time indoors
- Indoor air often 2-5x more polluted than outdoor air
- Growing awareness post-pandemic
- IAQ products offer good margins and recurring revenue

- MERV 8: Basic filtration, dust and pollen
- MERV 11: Better filtration, mold spores, pet dander
- MERV 13: Excellent, captures bacteria, smoke particles
- MERV 16+: Hospital grade, requires system modifications
Media Air Cleaners
Whole-house media filters offer 4-5" depth for better particle capture without excessive pressure drop. Popular options include:

Air Purification Technologies
UV Germicidal Lights
Two main applications:
- Coil-mounted: Keeps evaporator clean, prevents mold growth
- Air-stream: Treats circulating air, kills airborne pathogens
Electronic Air Cleaners
Use ionization to charge and capture particles. Require regular cleaning but no filter replacement.
Bi-Polar Ionization
Creates ions that attach to particles, making them easier to filter. Also neutralizes odors and pathogens.
Humidity Control
Whole-House Humidifiers
Types available:
- Bypass: Uses furnace heat, requires bypass duct
- Fan-powered: Independent fan, higher output
- Steam: Highest output, independent of heating
Dehumidifiers
