Indoor Air Quality

Americans spend roughly 90% of their time indoors, and more than half of homes have inadequate ventilation. In humid Florida, that combination shows up as odor, allergies and mold.

What we see in the field

Clammy air at 74 degrees is the complaint we hear most, and it is almost never the thermostat. It is oversized equipment, leaky return-side ductwork pulling humid attic air, or both. We measure indoor relative humidity before recommending equipment, because a dehumidifier bolted onto a duct problem just runs the meter faster.

Air filtration and purification are a real part of your air conditioning system, not an upsell. We give you an honest consultation on the air quality in your home, then install and warranty the product that actually fits your system, from UV bacteria-killing lamps to whole-home media air cleaners.

Products we install

  • Whole-home media air cleaners (MERV 11–16) that replace the flimsy 1-inch filter
  • HEPA-grade filtration for allergy and asthma households
  • UV-C germicidal lamps at the coil to stop mold and bacteria growth
  • Bipolar ionization and photocatalytic purifiers for odors and VOCs
  • Whole-home dehumidifiers that hold indoor humidity at 45–55%
  • Fresh-air ventilation dampers for tight, newly built homes

Why humidity is the Florida problem

At 75°F and 65% relative humidity, a house feels clammy and smells musty no matter how low you set the thermostat, and dust mites and mold thrive. Dropping humidity into the mid-40s makes 76°F feel better than 72°F did, and it costs less to run. A properly sized system plus a dehumidifier does that; a bigger air conditioner does not.

What improvement looks like

  • Noticeably less dust on surfaces within a few weeks
  • Musty smell gone when the system kicks on
  • Fewer allergy flare-ups indoors
  • A cooler-feeling house at a higher, cheaper thermostat setting

Common questions

Do UV lights actually work?
Coil-mounted UV-C is well documented at keeping the evaporator coil and drain pan free of biological growth, which is where most musty odors start.
Will a thicker filter hurt my airflow?
Not when it's installed correctly. Media cabinets have far more surface area than a 1-inch filter, so they filter better with less static pressure.
