Air Conditioning

How Does Your AC Work?

Air conditioning systems help keep your home cool. But many home and business owners do not understand just how their air conditioning systems work. And that is unfortunate. Knowing how your air conditioning system works can help you know exactly when to call in the repair and replacement professionals. Let’s go over the air conditioning process.

We can break down the air conditioning process into the following cycles of operation:

  • Evaporation
  • Compression

Let’s explore each cycle in a little more detail below.


The evaporation cycle in modern air conditioning is where the actual cooling happens. During this cycle, the air conditioning system pulls in air passes it through the evaporator coil. The evaporator coil has very cold liquid refrigerant chemical running through it. When the air passes over the cooled coil, the heat from the air transfers to the refrigerant. This heat transfer process transforms the liquid refrigerant into a gas and cools the air. Once cooled, the system distributes it throughout your building.


The compression cycle in modern air conditioning actually doesn’t involve cooling the air at all. During the compression cycle, your air conditioner takes the gaseous refrigerant from the evaporation cycle and compresses it back into a liquid and then moved back to the evaporator coil to start the process all over again.

During the compression cycle, your air conditioning system uses both a condenser coil and a compressor. The system runs the gaseous refrigerant through the condensation coil and passes outside air through it. This first stage in the process saps the heat from the refrigerant and transfers it to the outside air. Then, after the condensing coil saps as much heat as possible, the compressor finishes the job and passes the newly liquidized refrigerant back to the evaporator coil to start the process all over again.

Leaky Ductwork – Signs and More

There are several signs that point towards leaking ductwork in your air conditioning system. The three most common and serious signs of duct leaks include:

  • Sign 1 – Increased utility bills
  • Sign 2 – Hot or cold spots (hard to cool rooms)
  • Sign 3 – Visibly Damaged Ductwork

Sign 1 – Increased Utility Bills

If you have noticed an increase in your monthly utility bills, then leaking ductwork very well may be the source of your trouble. When ducts leak, the HVAC systems that feed them have to work much harder to reach the temperature set on your thermostat. The harder they have to work, the more energy they consume, and the higher your utility bills will be. So, if you have noticed an increase in your utility bills but know you haven’t increased your use of energy-hungry appliances, then call our ductwork professionals straight away.

Sign 2 – Hot or Cold Spots

Hot or cold spots and difficult to cool/heat rooms are both signs of duct leaks. When ducts leak, the cooled/heated air being delivered by them does not reach the designated location. This causes hot and cold spots in your building that can be quite difficult to resolve without replacing/repairing your ductwork. Another thing that can cause hot and cold spots is a poorly completed air balance. Regardless of the source of your hot or cold spots, contact the Ground Zero Plumbing & A/C LLC HVAC experts the moment you notice them.

Sign 3 – Visible Damage to Ductwork

Damaged ductwork is by far the most common cause of leaks. To see if you have damaged ductwork, simply pop your head up in your attic or down in your crawlspace and give your ducting a visible inspection. If you notice any visible signs of damage, then leaks are basically inevitable. Contact us and our team of reliable air conditioning experts if you notice any damage to your ducting.
