The air inside your house.

Indoor air pollutant levels can run 2 to 5 times higher inside homes than outside.

Of our time is spent indoors, per EPA.

Indoor humidity EPA recommends. Keep it below 60% to hold back mold.

EPA advice: use “at least MERV 13 or as high as your system will accommodate.”

EPA lists short-term effects like eye, nose and throat irritation, headaches, dizziness and fatigue.

Moisture. EPA’s own mold guide says to “keep air conditioning drip pans clean and the drain lines unobstructed.” That’s part of every tune-up.

EPA warns against air cleaners that make ozone. Trane CleanEffects emits under 0.3 ppb.

Sticky at 74°? It’s the moisture, not the temperature. Longer, slower cycles (two-stage / variable-speed) pull more water out.

Whole-home air cleanerRemoves “up to 99.98% of particles and allergens” as small as 0.3 microns — Trane says “100 times better” than a standard filter.
CADR 1,200 · Reusable — vacuum or rinse every 3–9 months · Emits less than 0.3 ppb ozone

FiltrationMost home systems take MERV 8–13. Higher MERV adds airflow resistance, so we match it to your blower.
1" filters: every 90 days — every 30 with pets, allergies or heavy use · Thick media (e.g. QuikBox): about every 6 months · Change sooner if it looks dirty or bills climb

HumidityTrane: dehumidifiers help “prevent mold and mildew growth.”
Target 30–50% RH (EPA) · Fixes musty smells the AC alone can’t

HumidityFor dry winter heat — cracked lips, static, dry sinuses.
Rarely needed in SA summers; useful in cold snaps

Fresh airBrings in fresh outdoor air while recovering energy — useful in tight, newer homes.
Pairs with filtration so fresh air isn’t dusty air
