Addison HVAC | Defrost - Free Heat Pumps + 4 Major Benefits
"FrostShield opens up a major portion of the country that previously could not use air source heat pumps due to low ambient temperatures. It is a game changer for clients with electrification in mind and continues the leading position Addison has obtained as an innovator of the DOAS market."

Normal operation
The air-source heat pump operates as it normally would when in heating mode sending fresh, clean air into the building.
FrostShield Detection
As conditions near frosting levels, FrostShield detects outdoor coil temperature levels and determines the precise amount of hot discharge gas needed to prevent frost from forming.
FrostShield Protection
FrostShield maintains the coil temperature above the threshold where moisture condenses and frost forms. This prevents the unit from switching to cooling mode, saving energy.
