Components of an Auto AC Unit


The compressor plays a crucial role in the cooling system by pressurizing the refrigerant from its gaseous state and pumping it throughout the system. Powered by the serpentine belt, it serves as the central component that ensures effective cooling.


After leaving the compressor, the gaseous refrigerant flows into the condenser. In this crucial step, the refrigerant undergoes a transformation from gas to liquid form. The condenser, resembling a radiator in appearance, effectively removes heat from the high-pressure refrigerant, generating a substantial amount of heat in the process.


The receiver’s task is to filter the refrigerant, which is now in liquid form and under high pressure, in order to eliminate any debris or water present. These impurities have the potential to harm the air conditioning system.

Thermal Expansion Valve OR Orifice Tube

While most car A/C systems are similar, there is one key difference that sets them apart: the use of either an orifice tube or a thermal expansion valve. Regardless of the specific device, their purpose remains the same – to monitor refrigerant flow and alleviate pressure, allowing for the expansion of refrigerant into its gaseous form.


The evaporator serves a delightful purpose: it facilitates the rapid expansion of liquid refrigerant, swiftly cooling the air. Typically positioned behind your dashboard, it boasts fins and pipes that lend it a radiator-like appearance. A blower fan propels air across the evaporator, directing it straight into the cabin of your car.

My car broke down during a trip to Brigham City from Salt Lake City. Master Muffler took care of me going well above and beyond. The price they quoted was just and accurate. I was happy and I believe they were honest and good with their treatment of me and the issue. I’ve used this Master Muffler in the past and have always felt good about the interaction. I’d recommend them as a mechanic to go to.

~Matt Eyre

They always are courteous and the work I want done is all that is done. They never try to sell you something you don’t need. Their prices are good and I trust what they say is what they will do. If anyone in Brigham needs work done I would not hesitate to recommend Master muffler.

~ Henry Kuglar

“I’ve worked with Jeremy and Jared over there and both are great people who care about their customers.  I definitely have had my share of bad experiences with auto mechanics but not here.  I have found them honest in all my interactions to date (several) and quite reasonably priced based upon my experience.  They do way more than mufflers and brakes also so don’t let the name hold you back.  In fact, I have only seen them for other repairs and maintenance.  Will go back!”

~ Tyson Hemphill

Master Muffler is great.  Had some issues with my car and they went above and beyond to take care of it.  Jeremy and Jared really are great to work with.  Would highly recommend.

~ Zenock Bishop

Jared is the real MVP. Everyone was so nice here and they got us  in after breaking down on the highway. Highly recommend this amazing service. Now we can safely get back home.
