How does your HVAC system work?

The HVAC system is kept on an iterative cycle to fulfill its responsibility to provide hot or cold air as needed. How did this happen? Consider the function of the components below.

Ventilation system

There are three types of ventilation systems – supply, exhaust, and balance. The exhaust system uses a fan to draw air out of the house. This reduces the air pressure inside and allows a natural flow of air to the outside. 

An air supply system does the opposite – it pumps air into the building to remove old, stagnant air. A balanced ventilation system uses a supply fan and exhaust fan to push old air out and let fresh air in.

Air conditioning

An air conditioner usually consists of two units, an indoor unit called the evaporator and an outdoor unit called a condenser. The condenser is on the high-pressure side of the system. The compressor converts the refrigerant into gas under high pressure and sends it to the compressor. You can find affordable HVAC supplies in NJ via
