![]() How often do I need my A/C system “recharged”? So chill, your A/C is only an inspection away from cooler days. How’s the air feeling in your ride? Are you refreshed and cooled with full air flow when your A/C is pumping? Well, if you answered “Yes, I am as cool as a cucumber,” you can cross A/C inspection off your list.įor all the “No” respondents: do you fall into the “my A/C is not cold enough” or the “it’s taking way too long to cool down,” side of the spectrum? Don’t sweat, stop in for an A/C Performance Check and we’ll have you back rolling down those hot summer streets cooler than ever. Now that you know what being cool is all about, if you have problems being cool, set up an appointment at Firestone Complete Auto Care for an A/C Performance Check. Complicated, but aaaaaaaaah is it refreshing! ![]() The ventilation system’s blower motor blows air over the cold evaporator and pushes cool air into the passenger compartment. The evaporator is like a mini radiator (not to be confused with the heater core - they are two separate things) inside the dash of your ride that gets cold as it further lowers the temperature of the refrigerant and, additionally, removes moisture from the air. It passes through the receiver/dryer where contaminants and moisture are removed, and then on to the expansion valve/accumulator where the refrigerant is slowed down further, causing it to lose pressure and temperature before it gets to the evaporator. It loses heat as it flows through the condenser (that second radiator looking thing in front of the radiator). Turn the A/C on and the compressor compresses the system’s refrigerant (Freon) raising its temperature. The Cliff’s note version is simply about changes in pressure causing changes in temperature. It really is thermodynamics but we’re not gonna go there. ![]() In fact, the cold air generated by your A/C system is actually hot air with hot gases removed during a multi-step process. But, believe it or not, there’s no ice machine inside (but at one time ice was used to cool people’s rides down). When the A/C system kicks in on those hot, sweaty days, that’s something we all relish. We all want the ultimate chill blasting out of our vents especially when it comes to surviving the hot concrete jungle. ![]()
