How to Tell Which Refrigerant Your Car Uses — Best Guide for Boise Drivers
If you're booking AC service in Boise, one of the first questions the best mobile mechanics will ask is: does your vehicle use R134a or R1234yf? It's a critical question because the two refrigerants are not interchangeable, and not every shop in the Treasure Valley is equipped for both. The Hop Shop offers the best mobile AC service in Boise for both refrigerant types — here's how to tell which one your car uses and why it matters.
Why Knowing Your Refrigerant Type Matters
Your vehicle's AC system is designed for one specific refrigerant. The service ports, seals, pressure switches, and compressor are all engineered for either R134a or R1234yf — never both. If you take your car to a shop that isn't equipped for your refrigerant type, you'll be sent to a dealership or turned away entirely. That's why The Hop Shop invested in equipment for both, making us the best mobile AC service option in the Treasure Valley for any vehicle, new or old.
The Best Ways to Identify Your Refrigerant Type
1. Check the Under-Hood Label
The best and fastest way to identify your refrigerant is to look under the hood. Most vehicles have a label or sticker that specifies the refrigerant type and the system capacity. This label is typically located:
- On the AC compressor itself
- On the radiator support or front crossmember
- On the underside of the hood
- Near the AC service ports (the metal fittings where refrigerant is added)
The label will clearly state either "R134a" or "R1234yf" along with the charge capacity in grams or ounces.
2. Look at the Service Port Fittings
R134a and R1234yf use different service port fittings to prevent accidental cross-charging. This is one of the best visual indicators:
- R134a: Service ports have a quick-connect fitting with a larger diameter (approximately 13mm high-side, 7mm low-side)
- R1234yf: Service ports have a smaller, flat-style quick-connect fitting that looks noticeably different from R134a
If you're not sure what you're looking at, the best move is to let a professional confirm it. Enter your vehicle info in The Hop Shop App and we'll verify it for you.
3. Check by Model Year
As a general rule:
- 1995–2017: Most vehicles use R134a
- 2018 and newer: Most vehicles use R1234yf
- 2013–2017: Some manufacturers began transitioning early — it varies by make and model
While model year is a good starting point, it's not definitive. Some manufacturers switched earlier than others. The best way to be certain is the under-hood label or a professional inspection.
4. Use The Hop Shop App
The best way to confirm your refrigerant type without lifting a finger? Enter your vehicle's year, make, and model in The Hop Shop App when booking AC service. We'll confirm which refrigerant your vehicle uses and bring the right equipment to your appointment.
Common Vehicles and Their Refrigerant Types
| Make | Model | Typical Refrigerant |

| Ford | F-150 (pre-2021) | R134a |
| Ford | F-150 (2021+) | R1234yf |
| Chevrolet | Silverado (pre-2022) | R134a |
| Chevrolet | Silverado (2022+) | R1234yf |
| Toyota | Camry (pre-2020) | R134a |
| Toyota | Camry (2020+) | R1234yf |
| Honda | Civic (pre-2017) | R134a |
| Honda | Civic (2017+) | R1234yf |
| Jeep | Wrangler (pre-2018) | R134a |
| Jeep | Wrangler (2018+) | R1234yf |
This table is a general guide — always confirm with the under-hood label or through The Hop Shop App.
What Happens If You Use the Wrong Refrigerant?
Using the wrong refrigerant can cause serious damage to your AC system. The service ports are designed to be physically different to prevent this, but if someone forces the wrong refrigerant into the system, you could face:
- Compressor failure due to incompatible lubricants
- Seal and hose damage from chemical incompatibility
- Voided warranty coverage
- Reduced cooling performance
- Potential safety issues (R1234yf is mildly flammable and requires specific handling)
This is why it's so important to use the best mobile AC service — one that has the right equipment for your specific refrigerant type.
