Yes, AC recharge kits do work to temporarily make your air conditioner blow cold again, but they are generally considered a band-aid fix. A car's AC is a closed system; if it is low on refrigerant, it means you have a leak that needs to be properly repaired by an ASE-certified mechanic.
DIY AC recharge kits work for temporarily making your air conditioning blow cold, but they are generally considered a "band-aid" rather than a true fix. Because car AC systems are closed loops, low refrigerant means you have a leak. If the leak isn’t patched, the refrigerant will simply escape again.
Recharging won't fix a refrigerant leak. If your AC stops blowing cold air again shortly after a recharge, check for leaks and repair them before adding more refrigerant. Each vehicle has specific refrigerant requirements. Always follow the recommended guidelines to prevent damage to the AC system.
Subaru Foresters typically use R-134a or R-1234yf refrigerant. To know exactly which one your vehicle requires, check the factory A/C label located under your hood. Foresters manufactured before 2014 usually use R-134a, while newer models typically use R-1234yf.
A DIY A/C recharge costs $40 to $130 and takes about 15 minutes, making it a cheap, quick fix. However, a professional service ($250 to $350) is safer and more reliable. Pros locate leaks and use calibrated machines to measure, vacuum, and refill the exact amount of refrigerant.
The 3-minute rule is a simple but important guideline: wait at least three minutes after turning your air conditioner off before turning it back on. That short pause gives the refrigerant pressure in the system time to equalize.
The overall best AC recharge kit is the A/C Pro R-134a Ultra Synthetic kit. It is highly regarded for its reusable trigger dispenser, built-in pressure gauge, and advanced formula that both replaces lost refrigerant and seals common leaks in rubber hoses and O-rings.
As of January 1, 2020, the United States banned the use of the R22 refrigerant, commonly known as Freon.
The average cost for a Subaru Forester AC Recharge is between $241 and $325.
Honda and Subaru began to introduce the new refrigerant with the 2017 models. From 2017 to 2018, BMW changed all of its models to R-1234yf. As of 2018, 50% of new vehicles from original equipment manufacturers (OEMs) are estimated to use R-1234yf.
The Dangers of DIY Recharging
Recharging Refrigerant: If the refrigerant in your AC was low, it could take anywhere from 30 minutes to a couple of hours to get it back to the right levels. Once that's done, cooling should return to normal fairly quickly.
No. A car's air conditioning is a completely closed-loop system, so it cannot "consume" or "wear out" refrigerant. If your refrigerant is low, you absolutely have a leak.
Signs That Your Car's AC Needs to be Recharged
Black Death occurs when moisture contamination in an AC system forms corrosive acids that attack metal surfaces and break down compressor oil, resulting in a dark sludge that can damage components. It is caused by humidity entering through small leaks or using improper refrigerant.
An A/C recharge restores refrigerant (Freon) — the chemical that allows your system to produce cold air. Blowing warm air, weak cooling, or A/C that only works while driving are common warning signs of low refrigerant levels. Low Freon levels usually stem from a refrigerant leak, not normal wear and tear.
A car's AC needs to be recharged when it blows warm or weak air, takes too long to cool the cabin, or if the AC compressor clutch fails to engage. Other signs include visible frost on AC components, hissing sounds, or increased cabin humidity. Low refrigerant usually indicates a leak, requiring professional inspection rather than just a top-off.

Over time, an A/C system begins to lose its charge and become contaminated. If you notice that your vehicle isn't cooling, visit Jiffy Lube® for A/C evacuation and recharge.
The Rule of 5000 Rule is simple: Multiply the cost of the needed repair by the age of your air conditioner. If the result is greater than 5000, AC replacement is generally the smarter choice. If it's less than 5000, a repair might still be worth the investment.
Without air conditioning or traditional power grids, the Amish stay cool using time-tested, natural methods. They rely heavily on strategic architectural design, natural ventilation, modified routines, and manual cooling techniques to survive the summer heat.
One of the primary reasons for the switch from R-134a to 1234YF refrigerant is environmental impact. Traditional refrigerants like R-134a contribute significantly to global warming. While R-134a doesn't harm the ozone layer like older refrigerants (such as R-12), it still has a high Global Warming Potential (GWP).
DIY AC recharge kits are generally not recommended. While they can temporarily restore cool air if your system is only slightly low on refrigerant, they carry significant risks. Improper use can severely overcharge the system, introduce damaging contaminants (like moisture or "stop-leak" sealants), and cause thousands of dollars in compressor damage.
A compressor should last about 10 to 15 years but may have a reduced lifespan if you use your air conditioning system frequently. If your air compressor is going bad, you need to take your vehicle to an auto repair shop to have it replaced.
