Dirty evaporatorĭirty evaporator can also cause Equinox AC to blow hot air. You can use pressure washer for cleaning, but make sure its at low pressure setting, as high pressure can damage the delicate fins on the condenser. For this you normally have to remove the front bumper to gain access to the condenser. If the condenser is dirty on your Equinox, the simplest solution is to clean it. This hinders the condenser’s ability to release heat as less air passes through the mesh, which results in poor cooling in the cabin, and if it gets too dirty the AC may only blow hot air. Over time, grime, bugs and other small particles can build up on its surface and in the gaps of its mesh.

The air conditioning system in Chevy Equinox has a condenser coil that sits at the front of the vehicle, and is responsible for releasing the heat from the refrigerant into the ambient air. If the pressure is higher than the recommended pressure, let some refrigerant out preferably into a rag to avoid exposure. Low side pressure values R134a vs R1234yf Ambient TemperatureĬonnect the pressure gauge to the low pressure (L) port in Equinox.

Check your vehicle’s owners manual or look under the hood to find the type of the refrigerant your vehicle uses. The pressure values based on ambient temperatures differ depending on the type of the refrigerant. Most modern vehicles use R-134a refrigerant, but newer vehicles are increasingly using R-1234yf as a more environmentally friendly replacement. So, even if you recharged your Equinox AC at the recommended pressure, the system could still over pressurize when the ambient temperatures get warmer. The refrigerant pressure is affected by the outside atmospheric temperature. Ambient temperature affect on refrigerant pressure An overcharged system not only affects cooling performance but can also damage the compressor and sometimes can cause a major leak. Just like with low refrigerant, the AC in Equinox will blow warm air only if the AC system is overcharged with refrigerant. Note: See next section for recommended pressure values.

Remove the cap from the low pressure service port labelled L, and connect the AC recharge kit.Turn on the AC and set it to the coldest setting, and the fan speed to maximum.This information is typically located under the hood and/or in the owners manual. Check which type of refrigerant your vehicle uses.You can recharge your AC through the low-pressure port with a do it yourself AC recharge kit. One is labelled H for high-pressure and the other one is labelled L for low-pressure. There are two ports in the air conditioning system of Equinox.

How to recharge AC refrigerant in Chevy Equinox When the refrigerant leaks again, the leaking component will shine under UV light. The leak can be diagnosed by injecting small amount of fluorescent dye into the AC system.

Refrigerant leak in Equinox can be caused by leaking O-ring seals, leaking condenser or evaporator core, or a cracked hose. If the refrigerant level goes down again quickly, it means there is probably a leak. Just have it refilled and you can drive with pleasant temperatures again. If you don’t service the AC system in your Equinox for a long time, the refrigerant level will eventually get so low that the system loses its cooling capacity. Ideally, the refrigerant should never leak in a properly sealed AC system, but most car AC systems do leak small amount of refrigerant over time due to minor imperfections and will need recharging after every few years. Refrigerant leakĪ low refrigerant level in your Equinox does not necessarily mean there is a leak. This can happen due to a leak or if the AC has not been recharged for a long time. Insufficient amount of refrigerant in the AC system is one of the leading causes of AC blowing hot air in Equinox.
