Air Filtration Systems

These whole house systems are integrated directly into your already-existing HVAC ductwork to help filter out toxic particles and harmful contaminants from your air flow. You can significantly improve the quality of air in your home by installing and utilizing an air filtration system.

Air Purification Systems

Air Purifiers filter the air throughout your house by utilizing an electrostatic process that will help to cleanse the air flow around your property.

Humidifier Systems

Steve’s Plumbing & A/C Service – Big Island offers Whole House Humidifier and Dehumidifier Systems that work through your ductwork and help to balance the level of humidity in your home, whether it be too much or too little. Portable humidifier and dehumidifier systems are commonly utilized, but they are unable to service more than one room in your home. If you have issues with humidity in your home, whether it be an excess amount or lack thereof, you likely need a whole home system to make a noticeable difference in your air quality.

UV Air Purifiers

These air purification systems utilize ultraviolet rays to help eliminate and destroy biological contaminants such as mildew, mold, and bacteria that cultivate in your ductwork. Big Island, HI homeowners that are sensitive to these contaminants and suffer from allergies, asthma, or other respiratory issues can greatly benefit from UV Air Purification Systems.

We’ll improve the air you breathe with local service you can count on.

Indoor Air Quality Service In Big Island, HI FAQs

What makes indoor air quality assessment especially important on the Big Island?

The Big Island has a combination of air quality factors that don’t exist anywhere else in Hawaii: vog from active volcanism, which contains sulfur dioxide and fine acidic particulates; extremely high rainfall on the east side that drives mold risk; large numbers of properties using catchment water in open-air or semi-open construction styles; and the widest climate variation of any Hawaiian island. These factors create indoor air quality conditions that vary more by location and by season than on other islands, and understanding what’s actually in the air at a specific property requires measurement rather than assumptions.

How does vog affect indoor air quality on the Big Island, and can an assessment measure its impact?

Vog exposure indoors depends primarily on how well the building is sealed and what kind of air filtration is in use. A professional IAQ assessment can measure sulfur dioxide levels, fine particulate concentration, and overall air quality index inside the home, and compare them to outdoor readings taken at the same time. The difference between indoor and outdoor levels tells you how effectively the home’s envelope and filtration are protecting occupants from vog exposure. For households with members who have respiratory sensitivities, having this data informs decisions about filtration upgrades and ventilation management during vog events.

What contaminants beyond vog should Big Island homeowners include in an IAQ assessment?

Mold spore counts are particularly relevant on the Hilo side and in older homes with moisture management challenges. Catchment water properties should include a check for biological indicators and particulates that may be entering the home from the water supply. Carbon dioxide levels indicate ventilation adequacy, which can be poor in tightly sealed homes in vog areas where residents keep windows closed during events. VOC levels from building materials, furniture, and cleaning products are relevant everywhere. A complete assessment covers all of these rather than focusing only on the most visible concern.

How does an IAQ assessment differ for a property on catchment water versus one on county water?

The assessment process is similar, but a catchment property evaluation should include the water supply as a potential indoor air quality influence. Improperly treated catchment water can off-gas hydrogen sulfide, which adds to indoor sulfur odor issues alongside vog. The storage tank and distribution system can harbor biological growth that affects water quality and indirectly affects air in areas near the tank venting. Assessing the catchment system’s condition as part of a comprehensive Big Island IAQ evaluation gives a more complete picture than looking at air quality alone.

What improvements are most commonly recommended after an indoor air quality assessment on the Big Island?

Upgrading to a HEPA-grade or higher-efficiency air filter and sealing the air handler filter housing tightly to prevent bypass are frequently recommended to reduce vog and particulate infiltration. Whole-home dehumidification on the wet side of the island, UV air purifiers in the air handler to address biological contamination, and fresh air ventilation systems that can be switched off during vog events are other common recommendations. For catchment properties, treatment system upgrades are often recommended alongside HVAC improvements.
