Understanding Your Appliances
There are a lot of HVAC parts to your system, so when your air conditioning or heating quits working, and you have to call for HVAC service. After the technician has checked the exterior component and the interior component if they tell you there HVAC parts that need replacing, do you know what they are saying?
As a homeowner, you don’t have to know how to work on your HVAC system, but you need to know the basics, including the HVAC parts. The first basic you need to know is how to change the air filter each month. The other basic thing you should know is how to vacuum the coils. So, by having some idea about HVAC parts and more so that when you have a service call, you can ask questions and understand the answers.
What are the four major components of an air conditioning system?
It is a compound chemical refrigerant found inside air conditioning systems that change from liquid to vapor and return to liquid. For this chemical to cool your home through the HVAC system, it needs the following four HVAC parts from this HVAC parts list:
- A Compressor
- The heart of the system, the one part that is a must for the HVAC parts to work is the compressor. Like the human heart is pumping blood, the compressor is pumping this refrigerant compound at a precise rate and pressure through several other HVAC parts and systems. At this point, the refrigerant is in vapor form it is sucked into the compressor. The refrigerant is then compressed as it is pumped through, raising the temperature at an extremely hot temperature.
- A Condenser
- The refrigerant, while at a high temperature from the compressor, proceeds to the condenser coil where a fan blows air over it to cool it down. It is then liquefied. The refrigerant vapor, at high temperature, enters the unit as the heat energy in the vapor is removed by blowing air across the condenser coil. While this is happening, the vapor changes to a liquid, and that heat that will blow from the condensing unit heat your home.
- A Metering Device
- The liquid refrigerant flow is controlled by a metering device as it goes into the evaporator. This is area is where the high pressure and low pressure are divided, and the high-pressure liquid is passed through this component to the evaporator where the pressure drops.
- An Evaporator
- The refrigerant leaves the metering device and immediately enters the evaporator where a fan blows across the refrigerant. At a lower pressure, the refrigerant enters the coil and begins to boil the return to a vapor state, and the heat is removed from the air as it passes over the coil and the refrigerant absorbs it. Now, instead of blowing heat, it is blowing cold air that cools your home when the HVAC system is set on air.
What is the most expensive part of an air conditioner?
An HVAC with parts that make it work to cool and heat are particularly important to the entire process. There isn’t one that isn’t as important as the rest. So, if an HVAC technician were tell you that a certain part needs replacing, none of the HVAC parts we mentioned above can work properly with the others.

As you can tell from the HVAC parts description that we listed, an air conditioner is a complex unit with many different mechanisms. If one isn’t working in harmony with the others, the refreshing air, cold or warm, isn’t going to happen. Of all the many parts, the most expensive of all HVAC parts is the compressor.
How do I know if my air conditioner compressor is broken?
We have explained that of all the HVAC with parts that are required for your air conditioner to work, the AC compressor is most important. This is the HVAC part that pressurizes the refrigerant and keeps it flowing so that the other HVAC parts can function adequately, cycling on and off in a continuous manner.
Some slight issues can tell you the compressor is struggling and may need replacing soon.
- CHATTERING or TICKING sound
- This sound is similar to a gas burner when you turn it on and is indicating that the AC compressor is stressed and struggling. When you hear this sound, turn the unit completely off and contact your HVAC technician.
- CLICKING or Rumbling sound
- When you turn on the air conditioning and hear a clicking or rumbling sound, the motor mounts of the compressor have loosened and allowed the motor to bounce inside its casing, which is one of the HVAC parts that is repairable by a professional HVAC technician.
- LEAKS or PUDDLES
- If are leaks around the air conditioning system or you hear a hissing sound coming from the system, it could be a refrigerant leak that needs immediate attention by a professional. Leaking refrigerant is a health risk, causing coughs, eye irritation, headaches, and nausea. When left unaddressed, the other HVAC parts in the entire air conditioning system will completely freeze up. It isn’t getting the chemicals needed to create the cold air.
- SHORT CYCLING OR IRREGULAR TEMPERATURES
- If your air conditioning compressor turns off before the house is cooled, that s short cycling and means the compressor is turning off too early. There are several reasons an air conditioner will do this, with one being clogged or dirty air filters, a malfunctioning thermostat, or the HVAC system you have isn’t large enough for your house. A professional inspection will determine which of these it could be, and they will check the within the system to make sure they are in good working order.
What is the difference between HVAC HVAC parts and AC?
The air conditioning industry refers to HVAC, the acronym for heating, ventilation, and air conditioning. AC is the acronym for air conditioning and may refer to window units or a central system that is air condition only.
Closing Question – A Worthwhile Question
Is it worth replacing compressor on AC unit?
Even with routine cleaning and inspections, an HVAC system will quit working sometime between 10 to 15 years. It may experience any of the HVAC parts going out one at a time, and you can replace them with quality HVAC parts, but at some point, you have to decide if replacing the unit is the cheaper route in the long run. When it is the air compressor, you may want to replace it once, but a second time, especially if you have had other HVAC parts replaced, a new HVAC system is the better option.
