vehicle a/c systems can lose 5% of their refrigerant per year
causing the system to become inefficient. Another thing to remember
is the a/c system is used all year long, every time the defroster is
used the a/c system is activated to assist in removing the moisture
from inside the vehicle which can defog windows much faster than non
a/c equipped vehicles. It is recommended that modern a/c systems be
tested annually to assure peak performance. Schedule an appointment
with one of our factory trained professionals and let us make sure
you’re a/c system is running efficiently. We have the latest
equipment available to diagnose the computerized components, as well
as to service all the different systems including the newer systems
on hybrid and electric vehicles. Below is a brief explanation of the
major components that make these a/c systems work so well:
The compressor is a belt-driven device that compresses refrigerant
gas and transfers it into the condenser. The compressor is the core
of your vehicle's air conditioning system.
The condenser's primary function is to cool the refrigerator. The
condenser dissipates heat released by compressed gases and condenses
them into high pressure liquids.
The receiver is a metal container that serves as a storage
receptacle for the refrigerant; also known as a drier because it
absorbs moisture from the refrigerant and filters out harmful debris
and acids. You should change your drier every 3-4 years to ensure
quality filtration and prevent any chemical damage.
Orifice Tube/Expansion Valve:
The orifice tube (also known as the expansion valve) is a
controlling mechanism that regulates refrigerant flow throughout the
system. It also converts high pressure liquid refrigerant (from the
condenser) into low pressure liquid, so that it can enter the
The evaporator removes heat from the inside of your vehicle. The
evaporator allows the refrigerant to absorb heat, causing it to boil
and change into a vapor. When this occurs, the vapor leaves the
evaporator through the compressor, cooling your car and reducing
humidity. The evaporator houses the most refrigerant in the heat
transfer process and harmful acids can corrode it. This corrosion
typically damages the evaporator beyond repair.
