  • Evaporator coil.

These are mainly the major components of an HVAC (Heating, Heating, and Air Conditioning) system. Problems can occur in any of these elements. In addition, there is another component called the brain of this system, which is the thermostat. Problems can also occur in the thermostat.

There are four different types of HVA C sys tem s - split systems, hybr id systems, packaged heating, air systems, and free piping installations. The cost of the HVAC system is around 6,800-12,300 USD, and will last from 15-25 years. However, these are the primary thing about the HVAC system.
