Robinair Dual-Refrigerant Recovery & Recharge Suite
In Henderson’s punishing 115°F summer heat, a standard quick-recharge can can ruin your compressor. Our advanced Robinair dual-refrigerant service station automatically evacuates, dehydrates, and electronically weighs refrigerant to factory gram tolerances for both traditional R-134a and next-generation R-1234yf systems.
Common Vehicle Symptoms & Diagnostic Solutions
If your car or truck exhibits any of the warning signs below, our precision diagnostic equipment isolates the exact failure mechanism before minor issues become major repair bills:
Blowing Ambient or Warm Air
The Cause: Refrigerant charge has dropped below operating threshold due to seal degradation, or the compressor clutch / solenoid valve is failing to engage.
Musty, Moldy Vent Odors
The Cause: Bacterial and microbial growth trapped inside the dark, damp evaporator housing beneath your vehicle's dashboard.
Squealing or Grinding Under Hood
The Cause: Worn A/C compressor clutch bearing or excessive belt slip caused by a seizing compressor assembly.
A/C Cuts Out at Stoplights
The Cause: Condenser electric cooling fan failure or debris accumulation preventing heat dissipation across the front condenser core.

Frequently Asked Questions
Q: Why does my car A/C blow cold on the freeway but warm when idling at a stoplight in Henderson?
At stoplights, your vehicle relies entirely on the electric radiator/condenser cooling fan. If that fan motor is weak, or if your condenser is blocked by road grit, head pressure spikes and the ECU cuts off the compressor to prevent catastrophic explosion.
Q: What is the difference between R-134a and R-1234yf refrigerant?
Most vehicles built before 2018 use R-134a, while newer models use eco-friendly R-1234yf. The systems cannot be mixed, and modern R-1234yf systems operate under tighter tolerances that require dedicated, certified Robinair recovery equipment.
Q: Why did the DIY recharge can from the auto parts store not fix my A/C?
DIY cans only add refrigerant and often contain stop-leak sealers that clog expansion valves and destroy recovery machines. Furthermore, if your system has air or moisture trapped inside, adding refrigerant without pulling a deep vacuum only drives head pressures higher.
Q: How long does an A/C diagnosis and recharge take at Master Tech Automotive?
A comprehensive climate diagnosis—including electrical scanning, electronic leak testing, and vacuum decay testing—typically takes 45 to 90 minutes. We text you high-resolution inspection photos and an itemized Techmetric quote before any repair begins.
