Review on 🌀 VIVOHOME 110V 1/4 HP Rotary Vane Air Vacuum Pump and R134a AC Manifold Gauge Set Kit: Ideal for HVAC, Air Conditioning, and Refrigeration Recharging - ETL Listed by Justin Munajj

I bought it to repair my car's air conditioning. I've used many different machines and sensors over the years so I'm far from a beginner. After many attempts to vacuum my system, I kept losing the vacuum, albeit slowly. I tested the pump with my stand alone vacuum gauge and it held 30hp but could never get the gauges to hold a vacuum. I ended up taking the car to a local workshop and we checked that the pump was working great but the sensors must have an internal leak that we couldn't identify. I ended up letting them get out the vacuum and charge my air conditioner. Decided to return as I ended up spending more than the unit cost on reloading. If the sensors worked I would say this would be a great creative kit!
