During winter, indoor humidity levels often drop too low because cold outdoor air holds less moisture. This can lead to health issues like dry skin and respiratory discomfort, increased static electricity, and damage to wooden furniture and other possessions. It can also make the air feel colder, causing discomfort. Adding moisture to the air with...

HVAC stands for Heating, Ventilation, and Air Conditioning. It describes systems used to heat, cool, and circulate air in buildings. These systems help maintain comfortable indoor temperatures, control humidity, and improve air quality by filtering out dust and pollutants. HVAC systems are essential for creating a healthy and comfortable environment in homes, offices, and other...

An HVAC damper, also known as a duct damper, is a movable device located inside the ductwork of an HVAC system. Its main job is to control and adjust airflow within the ducts, allowing more or less air to flow to specific areas or rooms in a building. Dampers are commonly used in zoning systems,...

An HVAC zoning system is a heating and cooling setup that divides a building into separate areas or "zones," each of which can be independently controlled to maintain different temperatures. This system uses motorized dampers installed in the ductwork to direct airflow to specific zones based on the thermostat settings for those areas. By allowing...

A type of HVAC system that combines a traditional gas furnace with an electric heat pump to maximize energy efficiency and comfort. The system automatically switches between the heat pump and furnace depending on factors like outdoor temperature and energy costs. The heat pump is typically used for moderate heating and cooling needs, while the...

A hybrid system, also known as hybrid heat, is an energy-efficient HVAC system that combines two heating technologies—an electric heat pump and a gas furnace. The heat pump, which can also provide cooling, is used during milder weather for efficient operation, while the gas furnace takes over in colder temperatures when it becomes more effective...

IAQ (Indoor Air Quality) refers to the quality of the air inside a building or home, influenced by factors like temperature, humidity, ventilation, and the presence of pollutants such as dust, mold, pet dander, chemicals, and harmful gases. It directly impacts the health, well-being, and comfort of occupants. Good IAQ is achieved through proper ventilation,...

Ignition refers to the process of starting a combustion reaction in a fuel source, commonly found in HVAC systems like furnaces or boilers. This happens when a spark, pilot light, or hot surface igniter ignites the fuel (such as natural gas, propane, or oil), creating a flame that produces heat to warm air or water...

Indoor Air Quality (IAQ) refers to the condition of the air within and around buildings and structures, primarily as it relates to the health and comfort of the people who occupy them. It is assessed by measuring factors such as temperature, humidity, airflow, and the presence of pollutants like dust, mold, carbon dioxide, and volatile...

The indoor coil, also known as the evaporator coil, is an essential part of an air conditioning or heat pump system. It works by absorbing heat from the indoor air to cool your home. Inside the coil, cold refrigerant flows and absorbs heat from the air that passes over it. Once the heat is removed,...
