How an HVAC air conditioner works Warm air from the room is sucked in through a grille at the base of the machine The air flows over some chiller pipes through which a coolant fluid is circulating. This part of the machine works just like the chiller cabinet in a refrigerator.
Full Answer
What does an air conditioner actually do?
An air conditioner works via three major components: a compressor, a condenser, and an evaporator. An air conditioner works by shuffling heat around. The compressor pressurizes a refrigerant, the fluid that runs throughout the air conditioner. As the refrigerant gets pressurized, it starts to heat up, pulling energy from the room.
Why is my air conditioner not cooling?

Do portable air conditioners actually work?
Some portable A/C units work by sucking in air from inside the room and using a motor to cool the air. This type of unit has one hose that takes the hot air and moisture and blows it out the window.
How exactly does an air conditioner work?
This is the most basic sense of how a portable air conditioner works:
- The fan sucks the hot and humid air from the indoor room inside the portable air conditioner.
- Inside the unit, the hot and humid air is cooled down by condensing on cold coils. ...
- The cool air is vented back into the room.
- The moisture from the air is gathered and can be vented outside, or you have to remove the bucket manually.
How does a HVAC air conditioner work?
As the liquid refrigerant inside the evaporator coil converts to gas, heat from the indoor air is absorbed into the refrigerant, thus cooling the air as it passes over the coil. The indoor unit's blower fan then pumps the chilled air back through the home's ductwork out into the various living areas.
How does HVAC work step by step?
The steps an air conditioner takes to ensure the completion of the cooling process are as follows:Step 1: The Thermostat Signals The Need For Cooling. ... Step 2: The Refrigerant Absorbs Heat From Indoor Air. ... Step 3: Fans Blow Back Cooler Air To The House. ... Step 4: Heat Within The Refrigerant Is Released Outdoors.
Is HVAC the same as air conditioning?
Know the Difference An HVAC unit heats, cools, and ventilates your home; and an AC unit only cools your home.
What are the 3 types of air conditioning system?
Ducted Air Conditioning.Split System Air Conditioning.Multi Split Air Conditioning.Controls.
Does HVAC include furnace?
In addition to your air conditioner and furnace, HVAC includes combined systems like heat pumps and indoor air-quality equipment like air purifiers. It also encompasses the control systems and smart thermostats that help everything work together.
How long do HVAC systems last?
Remember, while the average HVAC system lifespan is anywhere between 10–25 years—based on your climate and what type of heating and cooling system you have. But your HVAC system may last less time than that if it has been overworked by insufficient insulation and unwanted airflow (due to unsealed air leaks).
Does HVAC include refrigeration?
HVAC and refrigeration are similar fields but with distinct differences. While students can receive HVAC training at a vocational school or a community college and learn about both at the same time, they may eventually choose to specialize in only one.

Does an HVAC system heat and cool?
HVAC stands for heating, ventilation and air conditioning systems. This system is responsible for heating and cooling your home and includes products like furnaces, air conditioners, heat pumps as well as ductwork, thermostats and other home comfort controls.
How does HVAC work in pharmaceutical industry?
This system is used to control the temperature of a designated space with the control of the moisture in the air, supply the area with fresh air by controlling the carbon dioxide and oxygen level. It also controls the contamination of airborne particles by regulating the movement of air.
What are the parts of an HVAC system called?
Some of the most important parts of your HVAC system are your heat exchanger, blower motor, combustion chamber, condenser, evaporator, and thermostat.
How does an electric HVAC system work?
When the thermostat is triggered, it sends those 24 volts of power from the red wire up a white wire back to the furnace. The power then snaps the relays, allowing the heat strips and fan to power on and start blowing warm air into the home. Remember, the strips in an electric heating element heat up very quickly.
What is HVAC system?
Your HVAC system (heating, ventilation, and air conditioning) is responsible for keeping your home cool in the summer and warmer in the winter. With a quality system, you’ll never feel uncomfortable, regardless of the outdoor temperature. But how do they work?
What is the air conditioner?
The air conditioner is the part of the cooling system that cools the air. It is located outside the home. It uses electricity and liquid refrigerant (or coolant) to cool the temperature of the ce. It sends hot air outside and pushes cool air inside. If you’re interested more specifically in the cooling side of things, take a look at our article on how central AC works.
What is ductwork in HVAC?
The ductwork is a series of ducts throughout the home. Ducts are pipes or tubes that conduct a substance throughout the area where they are installed. In the case of HVAC, the ductwork conveys the air - either hot or cold air based on thermostat settings - into vents throughout your home. The vents or registers in your home's floor or ceiling, are openings into the ducts, and how the air is delivered into each room.
How does forced air work?
In a typical forced air system, a heating element warms the air and the blower blows it into the duct system for distribution throughout the home. If the AC is running, the outdoor unit pulls warm air in, passes it over coils where the refrigerant cools it further, and then blows the cold air into the home.
What is the thermostat in HVAC?
The thermostat, located inside the home serves as the brain of the entire HVAC system. It controls the mode and temperature. When in heating mode, it will heat up the home once it reaches a certain temperature. when the set temperature (what temperature you want in the home) is achieved, the system will turn off. When in cooling mode, it will cool down the home once a certain threshold is reached.
Why is HVAC important?
Your HVAC system is mainly known for the fact that it keeps your home at the right temperature year-round - but it also helps ventilate.
What is the first step in an air conditioning system?
Inside the outdoor air conditioning unit, you’ll find the compressor, which is the first step of the air conditioning system. It compresses the refrigerant gas into a liquid to make it possible to travel through the pipes into your main air conditioning systems.
