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.
Freon, or coolant, is the chemical in the air conditioning system that cools the air. If the system is leaking, then this chemical will eventually run out. Today’s A/C systems are more sensitive than the older ones. The air conditioner will not work properly if there is not enough of this chemical.
Your air conditioner would not be able to produce cold air without the use of coolant. AC coolant is the substance that passes through the interior coils of the air conditioner to both lower the temperature of and dehumidify passing air.
Does coolant flush help AC?
A coolant flush will clean out the system that feeds your air conditioner, helping it run efficiently and keep your engine protected.

Why is my AC running but not blowing cold air in my car?
The most common causes of broken air conditioning are leaks or compressor issues. If your air is blowing cool but not cold, the problem could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge your AC.
How often does an air conditioner need coolant?
Never. You shouldn’t have to “add” refrigerant to a central air conditioner because it doesn’t “use up” refrigerant. The only reason you would ever need to recharge (that is, add refrigerant to) your A/C is if you have a leak; once the leak is fixed, the problem should be solved.
How do I refill my AC coolant?
If you need refrigerant for your air conditioner, you’ll need to contact a professional heating and cooling technician. Under EPA regulations, only a certified professional can recharge your home’s HVAC system. You should never try to recharge the A/C yourself, even if you have a home air conditioner recharging kit.

Why do I lose coolant when AC is on?
The most common reasons for coolant leakage in your home AC system are: Poor installation. If your unit is new, you may be the victim of a shoddy insulation job. Many homeowners look for the best price rather than hiring the highest quality installer.
How do you tell if your AC has a coolant leak?
Hissing or Bubbling Sounds
A refrigerant leak is the result of tiny holes or cracks in the coils. When coolant leaks through these holes, due to its high pressure, it produces a hissing noise. If the leak is large enough, there may even be a bubbling or gurgling noise coming from your unit.
How often should you top up coolant?
You need to check your engine coolant at least twice a year before summer and winter, ideally. Although, this advice may vary between car manufacturers. Coolant should be topped up whenever the level drops below the guide marks.
How do you know if coolant is leaking from AC?
If your HVAC unit suddenly stops cooling your home effectively, or if you can feel warm air blowing through your vents, it is a sign that your system may be leaking coolant. Other symptoms of a coolant leak are excessive condensation or ice build-up on the outside of the unit.
If you simply need a top off of refrigerant, you can expect to pay anywhere from $160-$375. If you need a repair for the leak itself, you can anticipate a higher bill. For refrigerant leak detection and air conditioning repair you may pay anywhere from $550 to $1,600.

How long does refrigerant last in a car?
Most AC systems can last around five years without a Freon top-up, unless you live in a very hot climate. Freon is a kind of refrigerant that is recirculated in your vehicle in a closed system to cool down the interior. So, your car won’t really run out of Freon since it is reused inside the sealed system.
