Indoor Air Quality Services in Highland, Indiana
In Northwest Indiana, we keep windows closed six months out of the year. That means the same air keeps circulating — carrying allergens, bacteria, mold spores, and household chemicals with it. Collins installs whole-home air quality systems that clean your air automatically, every hour of every day.
Why Indiana Homes Need This More Than Most
Our winters are long and tight. Sealed homes trap more than warmth.
Lake County is designated an EPA ozone nonattainment area — outdoor air regularly exceeds federal health standards. The Gary-Hammond industrial corridor and I-80/94 truck traffic contribute PM2.5 and diesel particulates to the region. When your HVAC runs, it cycles that outdoor air through your home. In winter, with windows sealed for months, there's nowhere for it to go.
Allergens & Pollen
Spring in NW Indiana brings heavy pollen from trees, grasses, and ragweed. Once it's inside, your standard furnace filter does little to stop it from recirculating.
Viruses & Bacteria
Closed homes in winter concentrate airborne viruses and bacteria. Poor air circulation means illnesses spread more easily between family members.
Dry Winter Air
Midwest heating seasons drop indoor humidity well below the healthy 30-50% range. Dry air cracks wood floors and furniture, increases static electricity, and irritates sinuses and skin.
Household VOCs
Cleaning products, paint, furniture off-gassing, and cooking release volatile organic compounds that build up in a sealed home over winter with no fresh air exchange.
Three Systems. One Healthier Home.
Collins installs all three systems — or just the one that addresses your biggest concern. We'll confirm the right fit for your system during the estimate — no major renovations required.
RGF REME HALO
In-Duct Air Purification
The REME HALO installs directly into your existing ductwork and uses advanced UV-C light and ionization to actively clean the air throughout your entire home — not just what passes through a filter. It creates ionized hydrogen peroxide molecules that travel through every room, neutralizing pollutants at the source.
- Reduces airborne viruses and bacteria up to 99%
- Eliminates mold, VOCs, odors, and allergens
- Works 24/7 — not just when HVAC is running
- Designed to treat air throughout the home via your duct system
- No replacement filters to buy or forget
- Quiet — you'll never know it's there
Aprilaire Whole-Home
Air Filtration
Portable room purifiers cover a single room. An Aprilaire whole-home filtration system is installed directly in your furnace or air handler, filtering every cubic foot of air that moves through your home. Far more effective than the standard 1-inch filters that most homeowners use.
- Captures particles as small as 0.3 microns
- Removes pollen, pet dander, dust mites, mold spores
- Installs in-line with your existing furnace or air handler
- Filters all the air — not just one room
- Ask us if it's a fit for your system — most homes qualify
- Low maintenance — filter changes once or twice a year
Aprilaire Whole-Home
Humidifier
A Midwest heating season drives indoor humidity down to 10-20% — well below the healthy range of 30-50%. Portable humidifiers can't keep up with a full home. An Aprilaire furnace-mounted humidifier works automatically with your heating system to maintain comfortable, healthy humidity all winter long.
- Maintains healthy 30-50% indoor humidity automatically
- No tanks to fill — connects directly to your water supply
- Prevents cracking in wood floors, furniture, and trim
- Reduces static electricity buildup
- Relieves dry skin, eyes, and sinuses
- Furnace-mounted — out of the way, runs quietly
