Compress

The first thing that happens in a refrigerant system is the compression of the refrigerant. The , a chemical compound that changes easily from liquid to a gas. When the refrigerant is pushed into the compressor, it is a low pressure gas. The compressor pushes the gas molecules together, heating them up as the pressure raises. The compressor is the piece that keeps the refrigerant moving, as the low pressure is continuously pulled into the compressor to try and create some sort of equilibrium. It’s also one of the pieces to be most careful of, because the piping that leaves the compressor to continue on easily burns exposed flesh.

Condense

Once the refrigerant has been pressurized, the hot gas gets pumped into the condenser. This is the part of the unit that faces outside of your home. When you find the condenser, you’ll find that there’s hot hair usually being blown out of it. Would you believe that that heat is the heat that was in your home? The condenser has a few fans that blow across the pipes, cooling the gas. While the fans are cooling the gas, the pressure pulls the molecules tighter together, and the refrigerant condenses again into a liquid. The temperature drops to a more manageable level, causing the piping to shift from burning hot to very warm.  The liquid has most of the heat from your home burned off, and begins to move along to the next part of the unit.

Measure

In order to keep the refrigerant moving at a constant pace, and in order to gauge whether the air conditioning is continuing to cool the home, and whether the machine needs to continue the cooling process or simply maintain the current temperature. This metering device is the computer that controls the situation and keeps track of how things are working. If you’re having electrical problems, or your air conditioning doesn’t seem to respond to your programming, it might be because of this little device. Most air conditioning repair that requires electrical components focus in on this metering device When the hot refrigerant is pumped through the device, electrical information updates your air conditioning unit on how much work it has left to do.

Evaporate

Finally, the now lower pressure liquid encounters the evaporator. With a lower pressure, the refrigerant liquid is now ready to cool the home. Fans in the evaporator blow over the pipes holding the liquid, causing the pressure to change yet again. The chemical reacts by boiling through an endothermic reaction. Endothermic means that while it boils and evaporates into a gas again, the chemical absorbs the surrounding energy and heat, causing the temperature around it to drop. The fans continue blowing, causing the now chilled air to be pushed into the house. As more refrigerant is pumped into the evaporator, more warm air from the home is chilled through the endothermic reaction. The gas now holds that heat from your home, and is ready to take it outside, leaving you with a cooler house.

Back again, the refrigerant, now a warm low pressure gas, is pumped into the compressor, where it repeats the process over and over again. This chemical continues to react, changing from a high pressure gas to a high pressure liquid to a low pressure liquid to a low pressure gas and over again. It’s the circle of air conditioning, and at the end of it all, the metering device reads that the temperature in the home is now exactly what you asked for. It shuts off the system, allowing the refrigerant to settle back down and fall still.

An air conditioning system works hard to cool your home, and utilizes chemicals like carbon tetrachloride to help you manage every hot summer out there! If you’re interested in air conditioning units and the like, why not consider a career in HVAC service? There are plenty of amazing , like Valley College, that are able to teach you the twists and turns of the fascinating machines that regulate the temperature in your home. Get your certification in air conditioning repair, and ensure that every home has efficient air conditioning that keeps the cool air in and the warm air out!

Troubleshooting

Something not working? Your main concern is finding out what. If there’s a sound, or a smell, you’ve got to be able to identify the problem. An HVAC technician is trained to recognize the problems first. No use in teaching you how to replace the coolant if you can’t recognize that that is where the problem lies. Valley College starts every technician’s career with troubleshooting, as it’s the first step in any situation.

Gathering Supplies

Once you’ve figured out what the problem is, you’ll need to know how to fix it, and what you’ll need. If something needs to be replaced, make sure you’ve got the right part for it, and know how to perform the replacement. Gather up the tools that you’ll need, and make sure that they’re well maintained and able to do the job. You’ll also need to get the appropriate gear on, as you don’t want to go crawling into an attic or stand outside for minutes on end without the right clothing. Being an HVAC technician can be dangerous, with exposures to cramped and heated attics, hot wires, or leaking units. Without the proper safety gear, you might end up walking out of the place requiring more bandages than when you came in. It’s important to acknowledge the dangers, and be cautious of everything you do, no matter the level of skill you possess.

Perform AC Repair

Once you’re ready to go, and know what you’re doing, get to work! Shut off the power to the unit, and begin the repair. The first necessity is to perform the replacement or to actually fix whatever the problem is. Once you’ve managed that, now is the perfect time to check on other things, like the cleanliness of the vents, any moisture or electrical leakage, or even the filters in the unit. As long as you’re always careful of the possibility of burns or shocks, you can perform a quick maintenance check to see if anything can be topped up or fixed. This helps keep the unit properly maintained, and can help stop larger problems from developing later on.

Perform a Safety Check

Now that you’re done with your repairs, give the unit another once over, and ensure that everything you’ve done is still in compliance with safety regulations. Check your repairs over once again to see whether there are any leaks or anything that needs reinforcement. It’s important to check twice before walking away, as you don’t want to inadvertently create a larger problem by leaving an exposed wire. Once you’re sure that everything you done has only helped the unit run more smoothly, and is still compliant to all the safety and efficiency regulations, you can put it back together and head on out. You’re done!

Cover Your Bases

If you’re performing this in a customer’s house, it’s up to you to alleviate their concerns. Start running the machine, and check it over again to ensure that it will indeed run smoothly. Even if you’re sure of your work, giving it that second glance will soothe your customer, and make them trust in your repair more. Don’t forget that you’re not just a technician that repairs air conditioning units. You’re also a service technician who deals with customers, and you need the customer service to match it! Being agreeable with them and providing that visible “check” will negate their worries and they will wave you goodbye with a large smile.
