  • Inadequate cooling
  • Weak airflow
  • Strange odors
  • Unusual noises
  • Excessive condensation

Components of an Auto AC Unit


The function of the compressor is to take the refrigerant in its gaseous state, pressurize it, and circulate it through the cooling system. As the central component of the cooling system, the compressor is powered by the serpentine belt.


The gaseous refrigerant goes from the compressor to the condenser where it changes into liquid form. The condenser has a radiator-like appearance and removes heat from the high-pressure refrigerant, which can result in high temperatures being produced.


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

Although most cars have similar A/C systems, one potential difference is the use of an orifice tube or a thermal expansion valve. Both of these serve the same purpose, which is to regulate the flow of refrigerant and relieve pressure, allowing the refrigerant to expand into gas form.


The purpose of the evaporator is to cool the air quickly by causing the liquid refrigerant to expand rapidly. It is usually positioned behind your dashboard and resembles a radiator with its fins and pipes. A blower fan blows air over the evaporator and into your car’s cabin.

Our excellence is reflected in the testimonials of our satisfied customers. Please take a look at what our valued clients have to say.

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.
