FAQs

What kind of refrigerant does a 2018 GMC Yukon take? ›

Compatible with both R134a and R12 refrigerants.

Why is my 2018 Yukon AC not blowing cold air? ›

The most common reasons a 2018 GMC Yukon ac isn't working are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor.

Which is the low side service port? ›

The low side line of the system will have a larger diameter metal pipe than the high-side. The low side service port is usually located between the AC compressor and evaporator. The low side service port will have a black or blue plastic cap that needs to be removed.

Where is the low pressure located in a low pressure system? ›

A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet.

Can you replace R134a with R-1234yf? ›

Internal heat exchanger for R1234yf refrigerant (photo: NRF) As you can see from the above description, R134a and R1234yf refrigerants are not completely identical and their substitution will always result in faster degradation of the A/C system and eventually lead to costly repairs.

How can you tell the difference between R134a and R-1234yf? ›

Perhaps the most significant difference between R134a and R1234yf is the environmental impact. As previously mentioned, R1234yf has a lower GWP compared to R134a. This means it has a lower potential to contribute to global warming when released into the atmosphere.

Why is R-1234yf preferred over R134a? ›

While R-134a has a Global Warming Potential of 1300, R-1234yf's GWP is less than 1. Another difference is that R-1234yf is classified as mildly flammable, but put into context, it is interesting to note that it still has the lowest flammability of any engine component-related fluid.

What is the most common cause of AC not blowing cold air? ›

If your central AC is not blowing cold air, the refrigerant may be the problem. The unit could be running low and need additional refrigerant added. The most likely cause of this is a leak. A leak not only keeps the AC unit from cooling properly, but also it can cause other issues within the home.

Why is my GMC AC not cooling? ›

Your compressor might have some leaks if you have low refrigerant pressure, or you might need to charge your compressor with Freon. It can be determined which refrigerant is faulty through a pressure test performed with the help of a professional.

Why is my AC running but not cooling to temperature? ›

A damaged or worn-out compressor can result in the AC running but not cooling. If you suspect a compressor issue, you'll need to seek professional help. Compressor problems often require technical expertise to diagnose and fix, and in some cases, the compressor may need to be replaced entirely.

How to find the low pressure side of an AC unit? ›

There should be two tubes coming out of the compressor. The larger tube is your low side port, or your low-pressure line.

Where is my AC drain line access point? ›

How do I find my AC drain line? Your AC has a condensate drain line running from the indoor to the outdoor unit. You'll find the end of the drain line somewhere near the outdoor unit (usually a copper or white PVC pipe). As for the access point, look for a vertical pipe with a cap near the indoor unit.

What is the low pressure side of the refrigeration system? ›

The low pressure side of the refrigeration cycle occurs primarily in the indoor unit. Cold, low pressure refrigerant leaves the expansion valve and enters the evaporator coil. The blower fan moves warm indoor air over the coil, and the refrigerant absorbs heat from the air. As it does so, it turns into gas form.
