Equipment From
The EPA estimates that indoor air can be 2 to 5 times more polluted than the air outside. From pet dander and dust mites to mold spores, volatile organic compounds (VOCs), and airborne bacteria, your HVAC system can circulate more than just heated or cooled air.
Poor indoor air quality can lead to:
Whether your home is sealed tightly for energy efficiency or you just want better breathing conditions for your family, IAQ solutions from RJ's offer cleaner, safer air—24/7.
We offer a full range of IAQ services designed to integrate seamlessly with your HVAC system. From single-room upgrades to whole-home systems, we can help you find the right solution for your needs and budget.
Upgraded air filtration helps trap airborne particles, improving air quality throughout the home. We install high-efficiency media filters from Aprilaire and other brands, which outperform standard 1-inch filters by capturing smaller particles like pollen, mold, and dust.
For advanced purification, we install Reme Halo in-duct air purifiers, which use hydroperoxide plasma and ionization technology to neutralize bacteria, viruses, VOCs, and odors.
Installed inside your ductwork or near the evaporator coil, UV lights destroy mold, bacteria, and viruses before they circulate through your home.
Balanced humidity supports better health, comfort, and even protects your wood floors and furniture. We install Aprilaire humidifiers and dehumidifiers sized to your home's square footage and seasonal needs.
In tightly sealed homes, ventilation is key. We offer ERV (energy recovery ventilator) systems that bring in fresh air without sacrificing energy efficiency.
Many indoor air quality issues go unnoticed until symptoms appear. If you or your family have experienced any of the following, it may be time to consider a solution:

Common symptoms of poor IAQ include:
If you notice these signs—especially when they're worse indoors than outdoors—it's time to consider a whole-home air quality assessment.
A media filter traps airborne particles like dust, pollen, and pet dander. They're installed in your HVAC return and typically rated MERV 11–16.
An air purifier, like the Reme Halo, actively neutralizes bacteria, viruses, mold spores, VOCs, and odors by releasing ionized hydroperoxides into the airstream. Media filters improve air cleanliness. Air purifiers go further to sanitize the air.
We recommend high-MERV media filters (MERV 13–16) from brands like Aprilaire for allergy sufferers. These filters capture microscopic particles like pollen, mold spores, and dust mites that can trigger asthma or allergies. For maximum protection, pair your filter with a UV light or in-duct purifier.
It depends on the type:
We recommend checking your filter monthly and changing it before buildup becomes visible. RJ's can set up a filter change schedule as part of your maintenance plan.
Yes. UV germicidal lights are proven to kill mold, mildew, bacteria, and viruses inside your HVAC system—especially on the indoor coil where moisture can cause microbial growth. They're ideal for homes with allergy or asthma concerns and can help keep your system running cleaner and more efficiently.
Installed directly into your ductwork, a whole-home humidifier adds moisture into the heated air stream during winter months. Systems like Aprilaire bypass and fan-powered humidifiers automatically regulate humidity levels based on outdoor temps and indoor readings—so your home never feels too dry or sticky.
The EPA recommends indoor humidity between 30–50%. Below 30%, you may experience dry skin, nosebleeds, and static. Above 50%, your home becomes prone to mold and dust mite activity. RJ's can install humidifiers and dehumidifiers that keep your levels perfectly balanced year-round.
Yes. While many IAQ solutions are duct-mounted, we also offer standalone and mini-split compatible air purifiers and humidity systems for homes with radiant heat, ductless mini-splits, or space constraints. We'll help you choose the right system for your home's layout and HVAC type.
Absolutely. The Reme Halo is ozone-compliant, generates no harmful byproducts, and is trusted in schools, hospitals, and homes. It uses ionized hydrogen peroxide molecules to clean the air, reducing airborne pathogens without affecting surfaces or causing irritation.
No—many IAQ upgrades actually improve HVAC efficiency. For example, UV lights keep your coil clean so your system doesn't have to work as hard. Media filters protect the blower motor from dust buildup. Smart humidity control also helps your home feel more comfortable at lower energy settings.
