Free in-home air-quality consult. Flat written pricing. 0% APR financing available.
If Any of This Sounds Familiar…
…it's almost always your indoor air, not just allergies.
Stuffy nose, watery eyes, scratchy throat that gets worse indoors
Musty or 'dirty sock' smell when the AC starts up
Cedar fever knocks the whole family out every winter
Dust and pet dander pile back up the day after cleaning
Headaches or grogginess that go away when you leave the house
Visible mold or slime on the AC drain pan or vents
What We Install
Real, manufacturer-trained installs — not the cheap eBay knockoffs. Most homes get the biggest improvement from a REME HALO + UV combo paired with a proper media filter.
REME HALO LED Whole-Home Purifier
$900–$1,200 installed
Installs inside your ductwork and uses ionized hydro-peroxide plasma to neutralize mold, bacteria, viruses, dander, smoke, and odors in every room — not just air that passes through a filter.
- Kills 99% of sneeze-borne bacteria & viruses mid-air
- Eliminates pet, cooking, and smoke odors
- Reduces dust and dander throughout the home
- Safe, low-maintenance LED cell (no mercury, lasts 4+ years)
- Most families notice the difference within a week
UV Germicidal Lights
$400–$700 installed
UV-C light mounted over your evaporator coil kills the mold, bacteria, and biofilm that grow in the dark, damp part of your AC. Cleaner coil = better airflow, lower bills, fewer drain-line clogs.
- Stops mold and slime growth on the coil and drain pan
- Improves airflow and system efficiency
- Reduces musty 'AC smell' on startup
- Pairs perfectly with the REME HALO
MERV 13 / 16 Media Filter Cabinet
$500–$800 installed
A real 4–5 inch media cabinet catches pollen, cedar fever, pet dander, and fine dust without strangling your blower the way a 1-inch MERV 13 will. Change it once a year instead of every month.
- Catches particles down to 1 micron
- Replace filter once every 6–12 months
- Properly sized to protect blower & airflow
- Big upgrade for allergy & asthma families
Whole-Home Dehumidifier
Quoted per home
South Texas humidity makes 75° feel like 82° — and feeds mold. A whole-home dehumidifier ties into your ductwork and pulls the moisture out so you can actually feel comfortable at a higher setpoint.
- Feel cool at 74–76° (lower bills)
- Stops mold-friendly conditions at the source
- Quiet — runs from your mechanical closet
- Great for new builds with tight envelopes
Our Honest Recommendation
For 90% of San Antonio Homes: REME HALO + UV + MERV 13.
That combo handles cedar fever, mold on the coil, pet dander, smoke, and odors — and it's the single upgrade we hear "I should've done this years ago" about more than any other. We won't try to bolt on equipment your home doesn't need. If a $400 UV light gets you 80% of the way there, that's what we'll quote.
