HVAC Systems – Main Components & Replacement Cost

HVAC Systems – Main Components & Replacement Cost

A HVAC (Heating, Ventilation, Air Conditioning) system is a heating, ventilation and air conditioning system that helps to regulate the temperature and humidity inside a building. HVAC systems are expensive and should be treated as a primary component of a house. The main components of a HVAC system include a furnace, condenser, evaporator and ductwork. There are 10 overall primary components of a normal HVAC system.

Furnace

The furnace is the main component of a HVAC system. It is responsible for heating the air inside the building. The furnace uses a variety of fuels, such as natural gas, propane, oil, or electricity, to generate heat. The air conditioner is the second main component of a HVAC system. It is responsible for cooling the air inside the building. A furnace size is measured in BTUs (British Thermal Units), which is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. A normal sized furnace for a 2000 square foot house is around 60,000 BTUs.

Air Conditioner

The air conditioner is the second main component of a HVAC system. It is responsible for cooling the air inside the building. The air conditioner uses a refrigerant to cool the air. The refrigerant is a substance that helps to remove heat from the air. The air conditioner also has a compressor, which helps to circulate the refrigerant. The size of an air conditioner is measured in tons. A normal sized air conditioner for a 2000 square foot house is around two tons. The refrigerant used in the air conditioner is called Freon.

Ductwork

The ductwork is the third main component of a HVAC system. It is responsible for distributing the heated or cooled air throughout the building. The ductwork consists of a series of pipes and vents that connect the furnace, air conditioner, and vents to each room in the building. The size of the ductwork is measured in square inches.

Condenser

The condenser is the fourth main component of a HVAC system. It is responsible for cooling the air inside the building. The condenser helps to cool the air by removing heat from the air. The condenser is located outside the building, and it uses a fan to circulate the air.

Evaporator

The evaporator is the fifth main component of a HVAC system. It is responsible for regulating the humidity levels inside the building. The evaporator helps to remove moisture from the air. The evaporator is located inside the building, and it uses a fan to circulate the air.

Thermostat

The thermostat is the sixth main component of a HVAC system. It is responsible for regulating the temperature inside the building. The thermostat uses a sensor to measure the temperature inside the building. The thermostat then turns the furnace or air conditioner on or off to maintain the desired temperature.

Humidifier

The humidifier is the seventh main component of a HVAC system. It is responsible for adding moisture to the air. The humidifier helps to improve the air quality inside the building. The humidifier is located inside the ductwork, and it uses a fan to circulate the air.

Dehumidifier

The dehumidifier is the eighth main component of a HVAC system. It is responsible for removing moisture from the air. The dehumidifier helps to improve the air quality inside the building. The dehumidifier is located inside the ductwork, and it uses a fan to circulate the air.

Air Filter

The air filter is the ninth main component of a HVAC system. It is responsible for filtering the air. The air filter helps to remove contaminants from the air. The air filter is located inside the ductwork, and it uses a fan to circulate the air.

Vent

The vent is the tenth and final main component of a HVAC system. It is responsible for exhausting the air. The vent helps to remove contaminants from the air. The vent is located outside the building, and it uses a fan to circulate the air.

If this sounds complicated, it’s because it is. HVAC systems are designed to keep the air in your home or office at a comfortable temperature year-round. But how do they work? Let’s take a closer look at the main components of a typical HVAC system.

Replacing your HVAC System

Over time, your HVAC system will start to wear down. The air conditioner will lose its ability to cool the air, the furnace will lose its ability to heat the air, and the ductwork will start to leak. When this happens, it’s time to replace your HVAC system.

The typical life span for a HVAC system is 15 to 25 years, depending on where you live. In more extreme climates where the system is running longer & harder, the lifespan will be shorter. Replacing a HVAC system is not for feint of heart – costs can range from $5,000 to $50,000, depending on the size of the house, location, and market conditions. Make sure you get multiple opinions and bids before you undertake the costly proposition of replacing a system. Often times, the machinery can be fixed by an honest repairman who is more concerned about helping you rather than selling you a completely new system.
