Scorpion UVC-LED System

The Scorpion is a UVC-LED disinfection unique system designed for use in residential and light commercial HVAC systems. The LED light has 30,000 hours of run time and with an integrated air flow sensor the Scorpion UVC-LED can last up to 5 times longer than traditional UV bulbs. The Scorpion UVC-LED is designed to kill mold, mildew, bacteria, viruses, and other harmful biological growth in the HVAC system and on the evaporator coil. The system will also help reduce foul and musty odors like dirty sock smell and will even help keep the drain line from clogging due to buildup in the condensate line.


Electronic Air Cleaners

Air Cleaner Repair, Replacement & Installation

Airborne particles contain some pretty nasty stuff. Dust mites, mold spores and carcinogens – all floating around in the air you breathe. One way to reduce the amount of toxins you’re breathing is to upgrade your air filter. Electronic Air Cleaners capture up to 99% of airborne particles as compared to the standard fiberglass filter which only traps about 50%.


Energy Recovery Ventilation

ERV Repair, Replacement & Installation

According to the US Environmental Protection Agency, indoor air quality can be up to five times worse than outdoors. Why? Your home is a living, breathing thing. It is constantly creating and trapping cooking gases, your exhaled breath and off-gases from building materials. A ventilation system provides an efficient way to trade your dirty indoor air for fresh outdoor air. No matter what the weather’s doing outside.


Humidifiers

Humidifier Repair, Replacement & Installation- Whole Home Humidification

A whole house humidifier will constantly monitor the moisture level in your home and keep it just right. Not only will you feel better, but you’ll spend less money on your heating bills each winter. More humidity will allow you to lower your temp AND raise your comfort. Win – Win!


Dehumidifiers

Dehumidifier Repair, Replacement & Installation- Whole Home Dehumidification

Your air conditioner is designed to control temperature, not humidity. You need humidity control to maintain comfortable, healthy conditions in your home. Excessive humidity is not only uncomfortable in the summer; it can also lead to mold.


REME HALO

Whole Home In-Duct Air Purifier

The REME-HALO® utilizes RGF’s patented REME® Cell technology with UV-C light to create low level, airborne hydrogen peroxide throughout the air-conditioned space reducing airborne and surface bacteria, viruses, odors, and mold.

The REME-HALO® in-duct air purifier actively neutralizes pollutants at the source ensuring excellent indoor air quality.


HALO-LED

Help protect your air and the environment

The HALO-LED™ is the industry’s first LED in-duct, whole home and building air purification system that is both mercury free and zero ozone compliant. The HALO-LED™ proactively treats every cubic inch of air conditioned space, reducing airborne and surface contaminants and pollutants through bi-polar ionization and revolutionary, patent pending, REME-LED™ technology.
