Annual Fuel Utilization Efficiency (AFUE) indicates a furnace's fuel-to-energy conversion efficiency. Higher AFUE ratings mean greater energy efficiency and lower fuel costs.

AHRI stands for the Air Conditioning, Heating, and Refrigeration Institute, a key trade organization representing manufacturers of HVAC systems, water heating equipment, and commercial refrigeration solutions. AHRI plays a crucial role in setting industry standards and promoting energy efficiency, ensuring high-quality performance for heating, cooling, and ventilation products.

Air conditioners cool indoor spaces by removing heat and humidity and releasing it outside. Central AC cools the whole home, while ductless AC targets specific rooms.

Air filters in HVAC systems trap dust, allergens, and harmful particles, improving indoor air quality. Homeowners can easily replace and maintain them.

Air handlers distribute air throughout your home to maintain comfortable temperatures. Typically installed indoors, they work alongside a heat pump for efficient climate control.

An HVAC air purifier is a device connected to your home's heating and cooling system, designed to remove contaminants and improve indoor air quality.

ASHRAE certifications recognize professionals with proven expertise in HVAC and refrigeration, sponsored by the American Society of Heating, Refrigerating, and Air Conditioning Engineers.

Bioaerosols are airborne microorganisms or biological particles, living or originating from living organisms, that are naturally present in the environment.

BTU (British Thermal Unit) measures the energy an air conditioning system uses to transfer heat. One BTU is the energy needed to change the temperature of one pound of water by one degree Fahrenheit.

BTUH, or British Thermal Units per Hour, measures the cooling capacity of an air conditioner. It indicates how much heat the unit can remove from a space each hour.

HVAC capacity refers to the heating or cooling output of a unit, measured in tons or BTUs, indicating the unit’s ability to regulate indoor temperature.

Clean Air Delivery Rate (CADR) indicates the volume of filtered air an air purification system delivers per minute. A higher CADR means the system is producing more clean air, enhancing indoor air quality.

Cold Climate Heat Pumps (CCHP) certified by ENERGY STAR® meet stricter standards for efficient operation in low temperatures, offering enhanced performance in colder climates.

CAE (Coefficient of Annual Efficiency) measures the heat output of a unit relative to the cost of fuel used. It helps assess the cost-effectiveness of heating systems.

The compressor in your air conditioner circulates and pressurizes refrigerant, allowing it to absorb heat from indoors and release it outdoors, ensuring efficient cooling.
