How Does It Work?
During the warm Alberta summer months we all want the ultimate chill of cold air blasting out of our vents. Truth is there is no ice machine inside even though in the old days that is what was actually used to cool vehicles down. The fact is the cold air generated by your A/C system is actually hot air with hot gases removed during a multi-step process.
Once you turn on the A/C and the compressor compresses the system’s refrigerant (Freon) raising its temperature. It loses heat as it flows through the condenser (that second radiator looking thing in front of the actual radiator. It passes through the receiver/dryer where the refrigerant is slowed down further, causing it to lose pressure and temperature before it gets to the evaporator. The evaporator is like a mini radiator inside the dash of your vehicle that gets cold as it further lowers the temperature of the refrigerant and, additionally, removes moisture from the air. The ventilation system’s blower motor blows air over the cold evaporator and pushes cool air into the passenger compartment. Complicated I know but it is every so refreshing once it’s complete.
What Is Refrigerant You Ask?
Refrigerant is a specially formulated mixture that’s sole purpose for transforming hot air into cold air. IT does this by absorbing and releasing heat, ultimately leaving cool air behind.
Typically refrigerant is referred to by its trade name Freon, the most common Freon’s are R-12, R134A and HFO1234yf. Freon is a pretty similar solution to motor oil and radiator coolant in that it is a working fluid designed for a specific system the Air Conditioner of your vehicle.
How Often Should My A/C Be Inspected?
You tell us. How’s the air feeling in your ride? Are you refreshed and cooled with full air flow when your A/C is pumping? If you answered “Yes, I am as cool as could be.” You can cross A/C inspection off your list.
For all the NO responders: do you call into the “my A/C works but it not cold enough” or the “It is taking way too long to get slightly cold air” side of the spectrum? Do not worry! Stop in for a A/C check and we can get you back to cool air over the short and hot summer streets.
How Often Do I Need My A/C System “Recharged”?
Only when the cool breeze no longer feels as chilly as you remember. Simple enough. Now, it is true that a well maintained A/C system can go its entire life without needing a recharge. But, that’s if you’re extremely lucky.
