What Parts Are in HVAC?

Distant view of furnace system in the basement of a Minneapolis home.HVAC is short for heating, ventilation, and air conditioning. It is the system of ductwork and vents that are all connected to provide proper airflow and comfortable temperatures inside your home. There are many components that work together to give either warm or cool air throughout your house depending on the season and the weather outside. HVAC inMN, is a must, so it is important that the following parts are all working at full capacity and are regularly maintained.

The furnace is the one of the biggest parts of the system. Its job is to blow the cooled or warmed air into the ductwork for distribution throughout the house. A heat exchanger is located inside the furnace. It pulls air from the house through an air return duct and uses either a gas burner or electric coils to heat the air to feed to the furnace.
The condensing unit uses refrigerant gas that goes through tubing and turns in to a liquid. At a special point, the liquid gets sprayed through a nozzle and causes evaporation and absorption of heat. The gas gets recycled back into the condenser while the cooled air pipes into the furnace. Evaporator coils are usually found attached to the outside of the furnace and are connected to the condensing unit. This component aids the condenser in getting cold air supplied to the furnace.

The whole system is controlled by a thermostat that is installed somewhere inside the house—usually a central location that is easily accessible to the resident. Newer systems use digital thermostats that can be programmed to meet specific criteria for heating or cooling your home throughout the day. The thermostat also houses a temperature sensor that detects when the system needs to turn on or shut off for a while in order to reach desired settings. This information is transmitted to the furnace either through hard wiring or over a wireless network. Each of these important parts can be found in your HVAC in MN.
