  • How is the PuriGuard Fresh System different from a traditional air purifier?
    The PuriGuard Fresh system is a comprehensive indoor air quality solution and offers several key differences compared to traditional air purifiers. Unlike standalone devices that take up floor or counter space, the PuriGuard Fresh system integrates into your HVAC system. This means you don't lose that valuable space in your rooms.

It proactively seeks out and neutralizing airborne pollutants, viruses, and bacteria as well as prevents them from circulating in all conditioned areas. Integrating PuriGuard Fresh with your HVAC system also allows your HVAC system to run frequently without energy spikes, leading to optimized comfort and purification.

  • Which is better: a portable AC unit or a ductless mini-split AC?
    A ductless mini-split AC is a better choice than a portable AC for several reasons. Mini-split ACs are more efficient at cooling, distribute cool air effectively, and provide consistent temperatures throughout the room. They offer greater installation flexibility, operate more quietly, and have higher energy efficiency ratings. Additionally, mini-split ACs are aesthetically pleasing as they require minimal installation and can be discreetly concealed, while portable AC units can be bulky and obstructive. Overall, ductless mini-split ACs offer superior cooling performance, versatility, energy efficiency, and aesthetics compared to portable AC units.

  • Why does my AC breaker keep tripping?
    If your AC breaker keeps tripping, it could be due to various factors, and one potential cause is a faulty compressor. The compressor is a crucial component of the AC system responsible for compressing the refrigerant, enabling efficient cooling. However, an aging or malfunctioning compressor may draw excessive current, leading to repeated breaker tripping as a safety precaution. In such cases, replacing the AC system becomes necessary to address the underlying issue and restore proper functionality. A new AC system with a reliable compressor can ensure efficient cooling, prevent further electrical disruptions, and provide a more reliable and comfortable indoor environment.
