What HVAC system should I buy? Heating, ventilation, and air conditioning ( HVAC ) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality.

HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics and heat transfer. Zoned HVAC systems can heat or cool individual areas of your home by controlling zone valves or zone dampers inside the vents or ductwork, which selectively block the flow of air. Zoned systems can save you energy and money by only heating or cooling certain areas when you need it. The HVAC system may also be responsible for providing fresh outdoor air to dilute interior airborne contaminants such as odors from occupants, volatile organic compounds (VOC’s) emitted from interior. This is the most thorough guide to understanding what is a HVAC System.

Evaporator coil from the indoor section of a direct-expansion HVAC system.

An air conditioner cools and dehumidifies the air as it passes over a cold coil surface. The indoor coil is an air-to-liquid heat exchanger with rows of tubes that pass the liquid through the coil. It has components both in and outside of the home.

Generally, it contains an air conditioner designed to cool refrigerant outside of your house, and a furnace with a fan or coil inside the house. HVAC systems are milestones of building mechanical systems that provide thermal comfort for occupants accompanied with indoor air quality. HVAC systems can be classified into central and local systems according to multiple zones, location, and distribution.

Maintaining your HVAC system is important for prolonging the life of your system as well as ensuring it works at maximum efficiency. Performing check-ups and basic maintenance on your HVAC system should at least occur twice a year, once in the fall and once in the spring. This ensures that the heating and air conditioning units are ready for heavy use come winter and summer before peak usage. A true central air-conditioning system uses ducts to distribute cooled air throughout the house.

In a “split system,” the most common design, refrigerant circulates between an indoor coil and a matching—meaning from the same brand—outdoor condenser with compressor (see illustration, below).
