A2L is a classification of refrigerant defined by ASHRAE Standard 34. It refers to refrigerants with low toxicity (A) and mild flammability (2L). A2L refrigerants, such as R-32 and R-454B, are gaining popularity due to their lower Global Warming Potential (GWP) compared to traditional HFCs like R-410A. While mildly flammable, they are considered safe when installed and handled properly. As Canada transitions to more climate-friendly refrigerants, A2Ls are becoming more common in residential and commercial HVAC systems.
An add-on system is a type of HVAC setup where a new heat pump or air conditioning unit is installed alongside an existing furnace or air handler. Common in retrofit applications, this configuration allows homeowners to upgrade to energy-efficient cooling or heating without replacing the entire system. The add-on unit works in tandem with the existing equipment to deliver year-round comfort. This approach can help reduce costs while improving performance.

Air conditioning is the process of cooling and dehumidifying indoor air to create a more comfortable living or working environment. Most systems use a refrigerant cycle to transfer heat from inside a building to the outdoors. In Canada, air conditioning can be provided by central systems, ductless mini-splits, or portable units. Modern models are designed for greater energy efficiency and may also improve indoor air quality. Choosing the right system depends on your climate, home size, and insulation.
