🌀 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 Review

Everything works as expected but the thread does not match regular r134a can adapters. I got the vacuum out, but I can't finish the job until I find a suitable adapter. must be activated.

Everything works as it should but the problem I had was the yellow hose fitting which is too small and does not screw onto the nozzle purchased from an auto parts store on the canister or the canister itself. Refrigerant R134a could not be filled to complete the job.

Gauge kit and vacuum pump work great. My air conditioner was fully evacuated and charged in less than two hours, and I spent most of my time making sure I didn't have any leaks. For those referring to the kit that does not come with Freon bottle adapter, Kit: https://www.amazon.com/gp/product/B07D18WVFD/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 works fine with this one Pressure Gauge Kit.

I'm writing this as an amateur who uses this set from time to time, so I can't solve the problems faced by a professional daily use. I am very happy with it installed. The pump works perfectly, the oil is included. The pump worked for about an hour with no problems. Nothing leaks, sensors are accurate. The price is great. The only criticism I have is that I wish the hoses were a bit longer, but if that's the case the price will go up. Recommended for DIY enthusiasts.

An HVAC installation typically requires the lines to be bled before refrigerant is introduced. VIVOHOME 110V 1/4 HP 3.5 CFM Single Stage Rotary Vane Air Vacuum Pump and R134a AC Manifold Gauges gave me the tools I needed to create that vacuum as well as gauges to determine the proper refrigerant pressure. The pump worked well and the gauges were easy to read. These tools allowed me to install HVAC without having to pay an installer, saving hundreds of dollars.

I needed a vacuum system that wouldn't break the bank. After all, the chances were good that I would no longer need it anytime soon after a successful repair. Problem: Most manufacturers charge too much for their system. Then I stumbled across this complete kit, it did its job well and will continue to work great should I need it in the future. I just added it to my tool collection. I paid for myself and can keep it to myself in addition to saving hundreds of dollars repairing it myself.

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.

7/18/21 - Replacement came within a day. Well! The box was again slightly damaged, but not that much. A small piece of the box is missing on the side. The replacement pump is great. Follow the directions for the first run as my original order. This one purrs like a kitten. Remember I wore earmuffs for the original because it was louder than my 3 gallon air compressor. This kit does not include the valve needed to connect the refrigerant bottle, so make sure you get one if you intend to use it…
