Air conditioning is a marvel of modern engineering that regulates the temperature, humidity, movement and quality of the air within an enclosed space. It does so by using a refrigeration cycle that involves the circulating of refrigerant (often called Freon) in a loop, changing from liquid to gas and back again at different temperatures and pressures.

The evaporator is on the cold side of an air conditioner or heat pump. It absorbs heat from air or liquid and can be used to cool a space, remove it from a solution, or both.
Its role is to quickly convert a low-pressure liquid refrigerant into a vapor, which can then absorb heat from the surrounding air or solution. It is commonly used with refrigeration systems and chillers. The evaporator is also found in home and car AC units.
The coils inside your air conditioning system’s evaporator are the unsung heroes of the cooling process. As you swelter during the Dallas summer, they work hard to draw warm air into the system and chill it before sending it back into the general atmosphere. The key to this process is the evaporator coil’s ability to rapidly heat up and liquefy water molecules in the air they’re drawn into.
A blower fan draws hot air from the room being cooled and forces it over the evaporator coil’s fins and pipes. Since heat always seeks an equilibrium, the hot air surrenders its energy to the cooler refrigerant, absorbing it quickly into a gas. The vapor then moves out through the blower fans and into your air ducts, where it disperses throughout the house or office.
The liquid-vapor mixture in the evaporator coil flows through a distributor, which helps ensure that all of the tubes receive a consistent amount of vapor and liquid. This is important to prevent the liquid from being forced into some tubes while the vapor is routed to others. This is known as entrainment and can cause performance issues in some systems.
If the evaporator coil is dirty or clogged, it won’t be able to absorb heat as quickly, which reduces the efficiency of your system. Taking simple precautions like changing your air filter every 1-3 months (based on type) can help keep dust from depositing on the coil and slowing down its function. It’s also a good idea to rinse the evaporator coil with clean water once or twice a year.
Compressor
The compressor is the heart of your air conditioner’s refrigeration process. Its job is to move refrigerant from liquid to gas and back to liquid as the cooling cycle requires. The compressor, along with the evaporator and condenser coils, is what makes your home cool by transferring heat from indoor air to the outside air.
When the AC system is operating in heating mode, the same process reverses. Refrigerant absorbs outdoor heat and carries it to the evaporator coils inside your house. This heat transfer allows your house to be warm and cozy while the cooled refrigerant flows back out through the condenser coils into the compressor, where it’s changed to high-pressure gas.
During the compression process, heat is added to the gaseous refrigerant by a compressor piston that spins around and moves up and down within an airtight cylinder. The up and down movement creates a vacuum that draws in gaseous refrigerant and compresses it, raising its temperature and changing its pressure to superheated temperatures.
To make this happen, a compressor motor uses a crankshaft to rotate up to 8 pistons in a block with airtight cylinders. The up and down motion of these pistons creates a vacuum that draws in gaseous cooling agents into the chamber and raises their temperature to superheated levels.
Once the refrigerant is in gaseous form, it’s pumped to the evaporator coils inside of your home. The evaporator coils remain cold because the hot air they pull in is absorbed by a refrigerant that changes to a liquid and transports the liquid to the condenser coil. Here, the evaporator coils return to their cold state while the liquid is transported back to the compressor to repeat the refrigeration process.
The compressor is the most important part of your air conditioning system and it should be inspected regularly by an HVAC technician. This is typically done as a part of the annual maintenance service to ensure that it continues to function at an optimal level. If you notice unusual noises coming from your compressor unit, or it fails to cool your house properly, this could indicate that the compressor has a problem that needs to be addressed immediately.
Condenser
The condenser is the outdoor portion of your air conditioning system and it plays a key role in your HVAC system. It works with the compressor to displace heat from your home’s indoor air. This is achieved by the refrigerant absorbing heat from your home’s air at the evaporator coil and then dumping that heat into the outdoor environment through the condenser coil.
A condenser is a component of not only your air conditioner but also refrigerators and steam power plants. They are designed to cool heated up refrigerant vapor into a liquid through the use of cooling fans, which in turn allows the cooled liquid to return back to the compressor for repeat cycles.
Problems with your AC’s condenser often result in a reduction in cooling performance. Like other components of an air conditioning system, your condenser requires regular maintenance to ensure it runs efficiently.
While there are many different problems that can affect an AC condenser, some are more common than others. For example, a condenser unit that is not level can cause vibrations, which can lead to damage and other issues. Another common problem is loose tubing connecting the condenser to other equipment in your air conditioner. This can lead to a loss of refrigerant, which can impact the overall cooling efficiency of your HVAC system.
Because your air conditioning’s condenser is located outdoors, it’s exposed to all kinds of dirt and debris. Even though it’s designed to defend itself from these contaminants, they can still accumulate over time. Dirty condenser coils make it difficult for your air conditioner to transfer heat, which leads to reduced energy efficiency and higher electricity bills.
You can help to prevent these problems by regularly cleaning your air conditioning’s outdoor unit. You can do this by removing dirt, leaves, branches and other debris that can get stuck on the condenser fan. You should also keep the area around your condenser clear of tall grass, bushes and other items that could restrict air flow. Another important step is to have your air conditioning’s condenser unit professionally inspected and maintained.
Ductwork
Ducts are the conduit through which conditioned air circulates in a residential or commercial HVAC setup. Similar to veins and arteries in the human body, ductwork carries both unconditioned and conditioned air throughout a building to ensure consistent comfort levels and optimum indoor air quality.
Leaks in ductwork, which are quite common, significantly reduce the efficiency of an HVAC system and also compromise indoor air quality. This is because leaking ducts allow unconditioned air to infiltrate the system and also forces the HVAC system to work overtime to make up for the loss of conditioned air.
Ideally, ducts are constructed of galvanized steel or aluminum, which are the best options for long-term durability and structural integrity. They should be insulated and sealed in order to prevent unwanted air leakage, which can result in increased energy costs. Insulation also helps to keep conditioned air in the system rather than escaping into the attic or crawl space of a home or business.
Ductwork is typically located in the attic or basement of a building and may run through walls as well. It can be configured in a variety of ways, including branching out from the main trunk line and heading toward various rooms in the house or office building.
The most popular types of ductwork include round metal ducts, rectangular metal ducts, flexible ducts and spiral metal ducts. These ducts are typically insulated and have a metal or aluminium coating that helps them withstand extreme temperatures. Other materials, such as fiberglass ducts, are also used, but they are less durable and can easily harbor moisture which leads to mold growth.
Signs that ductwork is in need of repair or cleaning include dust near vents, musty odors when the HVAC system is on and unexplained increases in heating and cooling costs. If you notice any of these issues, it is recommended to consult an experienced professional who can assess the ductwork and determine whether or not cleaning is required.
A reputable air conditioning service will be able to evaluate and inspect a homeowner’s or business’s current ductwork, provide recommendations on how to improve their ventilation system and then clean or replace the existing ductwork. This process will increase the efficiency of a home or business’s HVAC system and help to ensure that indoor air is consistently comfortable and healthy.
