What is the best refrigerant for a heat pump?
Heat pumps are an efficient way to heat your home. However, the refrigerant inside your heat pump significantly affects its performance and environmental impact. Refrigerants are the unsung heroes, enabling heat pumps to efficiently transfer heat by cycling through evaporation, compression, condensation, and expansion. Choosing a heat pump with the right refrigerant enhances its efficiency and reduces your carbon footprint.

Why is my heat pump freezing up?
Heat pumps are versatile systems that keep your home warm in winter and cool in summer. However, freezing problems often arise without enough airflow, low refrigerant levels, or malfunctioning components. While the Aira Heat Pump can work efficiently at temperatures as low as -25ºC, ice buildup can reduce efficiency and damage the system if left unaddressed.
