The Service AC System message can appear on your driver information center (DIC). When the DIC displays this alert, then there is an issue with your air conditioning system, and the system needs to be serviced.

Like every electrical component in your vehicle, multiple factors can be contributing to a climate control system issue. Faulty vents, a broken interior temperature sensor, failing fan motors, degraded fan relays, a refrigerant fuel leak and an insufficient amount of coolant in the engine.
The reason your car`s A/C system needs to be recharged is that, over time, the refrigerant gas that makes the system work will leak out of the system. This process can take many years — but, eventually, every vehicle will need its A/C system recharged.
A car`s air conditioning should be recharged every two years or so. However, if you notice any signs that your AC needs to be recharged, it`s important to take your car in as soon as possible. Taking care of your car`s AC is important for several reasons.
According to HomeAdvisor, the national average cost of an AC recharge is $300. Factors such as unit type, unit size, and refrigerant type can influence the final price, though most AC recharge costs fall between $200 and $500.
Residential Air Conditioner Freon Refill Cost
As mentioned earlier, Freon costs about $125 – $150 per pound. Most homeowners will pay in the range of $200 to $400 for a refill, depending on the type and size of their HVAC unit. If you own a larger r22 unit, you may have to spend $600 or more.
There are several things that can cause electrical problems for your car`s air conditioning. These can include failed switches, a blown fuse, a problem with the control module or something else. Fuses can short out and make the A/C stop working or a loose connection can create an electrical short that is easily fixed.
Though many car owners think they need to recharge or “top off” their air-conditioning system with refrigerant on a regular or annual basis, that`s not the case. An A/C system is a closed system, and if there are no problems, coolant is not consumed by the vehicle, nor does it escape.
Most AC systems in a car last for around 3-4 years, or five years, with recharging freon. Freon is a refrigerant recirculated in a closed system in your car to cool the interior. Since the car utilizes freon in an enclosed system, your car may never run out of it.
Rather than open a window and letting in pollution and noise, switching on your air con can have your vehicle cool and fresh in a matter of seconds. That being said, it does not make sense to leave your air con running all the time. In our experience, switching off your air con when you are not using it is a good idea.
Most vehicles have a label or sticker under the hood that indicate whether the refrigerant used is R-134a or R-1234yf. However, not all cars have this. If not, visiting the A/C Spec Database available through our Port Finder page will help you figure out what type of refrigerant your car needs.
Pop the hood and look for a label, which is usually white or bright yellow. On this it will either say “R-134a” or “R-1234yf,” and it may even say what the capacity is.
Common Reasons AC Doesn`t Run Cold
The most common causes of broken air conditioning leaks or compression issues. If you are feeling cool — but not cold — air, the issue could be a clogged filter, a problem with the cooling fan, signs of radiator trouble, or it could simply mean it`s time to recharge your AC.
While every unit is different, and every homeowner has a different understanding of when their central air conditioner is broken beyond repair, it`s fair to say that, with proper maintenance and care, you can expect a good 15 to 20 years of cooling from a new high efficiency air conditioning system.
Don`t. The U.S. Environmental Protection Agency (EPA) recommends not replacing Freon or refrigerant by yourself for both health and environmental reasons. Only an EPA licensed technician is legally allowed to reclaim Freon. Older formulas of Freon – specifically R-22 – are no longer used, but can still be found online.
Freon (which is really just a particular brand of refrigerant) lasts forever. It`s not like gas in car; it does not get “used up.” You see, your air conditioner`s refrigerant system is a “closed/sealed system,” meaning that it does not allow refrigerant to escape in any way.
Since the production of this substance has been so heavily restricted, finding Freon to re-charge an already-installed air conditioner has become difficult. What little Freon is made has become so rare that the prices have skyrocketed.
If you overcharge your car`s air conditioner, you could do some serious damage to your car`s compressor, put increased strain on your engine, and even cause overheating. You could also just end up with an AC unit that simply won`t turn on or doesn`t blow cool air.
Old, clogged air filters are often to blame for AC problems like frozen coils. If the filter isn`t the problem; you could be low on refrigerant.
A weak car battery can cause your auto air conditioner to function poorly or not at all. Car batteries need to have enough voltage to trigger the AC compressor, and while it may be strong enough to run the rest of your car, it may still be too weak to run your car`s air conditioning.
Typically, AC systems use “TR”-type fuses to ensure safe system operation. However, if you`re in a pinch and need to replace a fuse quickly, you can use a fuse that is rated for a lower amperage than what the system is rated.
Batteries in modern-day cars ensure that the engine always eats first, metaphorically speaking. When you start the engine in newer cars, anything that`s operated electrically – from the air conditioner fan to the radio – doesn`t draw power until after the engine is running.
That`s because refrigerant simply does not go bad or expire. As long as the cylinder or can is fully sealed (no leaks) and the valve is not open or broken, refrigerant will last in its container indefinitely.
Your A/C system uses a type of refrigerant (commonly called Freon) to cool the interior of your vehicle. Having a coolant flush performed will not help your A/C stay cool, or visa versa.
