Homeowners who are seeking to enhance their indoor air quality are always looking for effective solutions for their HVAC systems. You might have heard using ultraviolet (UV) light is a good, efficient way to fight airborne germs, bacteria and mold.
UV lights are a solution you can add to new or pre-existing heating and cooling systems. They are a strong resource in your search for healthier, cleaner air in your home or business. Let’s go over this germ-fighting equipment.

Ductless, mini split-system air-conditioners (mini splits) have numerous applications in residential, commercial buildings. The most common applications are in multifamily housing or as retrofit add-ons to houses with “non-ducted” heating systems, such as space heaters or wall heaters. They can also be a good choice for room additions and small apartments, where extending or installing supply ductwork (for a central air-conditioner or heating systems) is not feasible.
HVAC heat pumps are an innovative and energy-efficient technology that offers numerous benefits for both residential and commercial spaces. Unlike traditional heating and cooling systems, heat pumps work by transferring heat rather than generating it, making them highly efficient. Additionally, heat pumps deliver consistent and comfortable heating and cooling throughout the year by extracting heat from the outdoor air during winter and transferring it indoors, and vice versa during summer.
