Looking forEfficientReliableAffordableHVAC Systems?

Many of us take for granted how intricate our HVAC systems truly are. There are many components that work in harmony to keep our homes and businesses at just the right, comfortable temperature no matter the weather outside. In order to properly care for your system and prevent issues down the line, it is good to understand each component of your system and be able to spot signs of trouble before they lead to bigger problems. 

What Does The Word HVAC Stand For?

HVAC is an acronym for Heating, Ventilation and Air Conditioning. It refers to the various systems and mechanical components that regulate environmental conditions in a home, office building, and transportation systems to provide greater comfort. 

What Does A HVAC System Consist Of?

There are several components in HVAC systems that work congruently to regulate environmental conditions and knowing each term and how they work will help you save time and money when performing maintenance or repairs.

Thermostat: The thermostat is perhaps the most familiar part of any HVAC system. It is usually attached to a wall in the main area of a home and can be programmed or manually set to the desired temperature. Inside of it, there is a small thermometer that measures the air temperature and triggers either the heat exchanger or the evaporator coil-condenser into action. Technology has advanced thermostat controls with a growing variety of smart thermostats promising better efficiency, remote control and a host of other smart home control options.

Furnace: A furnace is usually quite large and can often be found in basements or large cabinets within a home. A furnace works by burning a fuel source, such as natural gas or electricity, to heat air that passes through it often propelled by a fan. 

Heat Exchanger: This is one of the most important components of an HVAC system, and it is imperative that it stays clean to prevent fire hazards and maintain peak efficiency. It consists of a sheet of steel that transfers heat into the air. 

Evaporator Coil: This component resembles the letter "A" and it works to cool the air passing through it. 

Condensing unit: This component can be found outside and houses a refrigerant gas and works with both the evaporator coil and heat exchanger.

Refrigerant Lines: Copper or aluminum coils that transport the refrigerant gas to the condensing unit. 

Ducts: Ducts & ductwork can be made of various materials and they form a network throughout the building or vehicle and work as a means of transporting the air to the desired destination. Ducts can be configure to provide heating & cooling zones that work off separate thermostats to better ventilate different areas of your home.

Vents: These are the final destination for the air to be released into the building or vehicle.
