Give our team a call for your indoor air quality system repairs & installations! Here are a few of the IAQ opportunities we offer:

Germicidal UV Lights – Simple, natural and inexpensive, ultraviolet light technology is a non-chemical process of disinfection. Installed into the HVAC system, UV lamps deactivate the DNA of viruses, bacteria and other pathogens, preventing the spread of disease. Germicidal UV-C light kills the mold and toxins that might otherwise thrive within heating and cooling equipment. Keeping the system contaminant-free promotes airflow, efficiency and healthier indoor air quality. Virtually silent and low in maintenance, these units are a benefit to any home or commercial space.

Whole-House Air Purifiers – Operating 24 hours a day, actively trapping 99% of airborne pollen, mold, dust and particles down to 0.3 microns, air purifiers help keep your family healthy. Designed to remove viruses and bacteria from the air and kill germs, air purifiers cleanse the air throughout the house multiple times per hour. Along with keeping a cleaner home, the unit helps protect the HVAC equipment and requires very little maintenance.

Merv-13 Air Filters – Upgrading to a MERV 13 filter can remove a great deal of virus carriers from the air you and your family breathes. Droplet nuclei are tiny, as little as 1 to 5 microns, and tend to remain suspended in the air. Circulation by the heating or cooling system worsens exposure. MERV 13 filters successfully trap over 50% of particles between 0.3 and 1 micron in diameter and over 85% of those between 1 and 3 microns. The capture rate rises to more than 97% for particles between 3 and 10 microns.
