HVAC systems provide heating and cooling to residential and commercial buildings. The system uses fresh air from outdoors to provide high indoor air quality. The system helps in controlling humidity, temperature, and airflow.
A good HVAC system not only aims to keep your home comfortable, but it also helps keep your indoor air clean through the concept of heat transfer, fluid mechanics, and thermodynamics. Below are the various components of the HVAC system that makes it work appropriately.
Thermostat
A thermostat system activates the heat exchanger or coil condensing unit to disseminate warm or fresh air accordingly. It is usually installed on the wall and can be programmed or manually set to keep your home at the desired temperatures.
A programmable thermostat can help you save on power bills as it can fine-tune your home's temperature even in your absence.
Vents
Vents are found near the ceiling and help distribute heated and cooled air from the duct system into your various rooms.
For continuous airflow, you should ensure that any objects do not block the vents.
Furnace
Due to its vast size, a furnace requires more space than the other parts of the system. It is, therefore, mostly found in the basement.
The furnace is designed to produce heat and distribute air across your rooms via air ducts. Depending on the furnace model, it can use various sources of heat, such as solar energy, electricity, heat pump, or combustion.
Evaporator coil
The evaporator coil, found in the furnace, helps cool down the air when you set the thermostat to a lower temperature. The coil captivates air that passes over it. This cold air is distributed throughout the rooms in your house.
Condensing unit
You can find this unit outside your home, packed with refrigerant gas and linked to the evaporator coil.
The condensing unit exchanges heat with the air that passes over it and sends it to the evaporator coil to vaporize into a gas.
Fixing Your HVAC System
Each component of the HVAC system relies on others to function properly. Therefore, it's essential to have an HVAC system that fully works, meets your comfort demands, and does not lead to excessive power bills. In case of a fault with one of the HVAC components, get a professional HVAC technician to repair or replace it. You can also seek professional advice when purchasing an HVAC system.
