There are two primary types of UV lights you can add to an HVAC system. One installs inside your HVAC ductwork and only activates while your system runs. Those systems work to purify your home’s air and offer some protection against mold growth within your HVAC system. The other type installs inside your HVAC itself, near its evaporator coil. There, it always remains on, preventing mold and bacteria from growing on the coil. It also offers some benefits for indoor air quality.
An HVAC UV light installation can deliver the following benefits.
- Improved HVAC efficiency
- Reduction of odors
- Minimizes airborne allergens
- Extends HVAC lifespan
- Minimizes airborne virus transmission
One of the best aspects of UV light systems is that they require minimal maintenance. Most require a bulb replacement annually to maintain maximum UV-C output. Air filtration systems, meanwhile, need frequent filter replacements or cleaning. Additionally, UV lights require very little electricity, so even always-on models are cost-effective to operate.
