If you are a GOT fan, then you know the term ‘Winter is Coming.’
But!
Summarization is scarier than winter if you are not well prepared for it. A well-maintained air conditioner is an essential part of today’s’ life, especially in summer though we also use it in winter but in the opposite way.
The primary function of an AC to provide you with clean, fresh, and cold air without hiccups.
Now, after installing an AC, our primary job is to maintain the system while serving. One of the main tools we should have for this purpose is an AC Vacuum Pump that enhances the functionality of an AC by removing the excessive moist air from the refrigerant. This way, we also get more life of an AC with the desired optimal functionality.
Now I will drive you through the complete buying guide for the AC Vacuum pump.

- It is also available in Stage 1 & different CFM’s 3, 6 & 12.
Wrapping it Up
When buying a Vaccum pump, then make sure to understand your project and what capacity you are looking for. After that, make sure to buy any reliable as it may be a risky call if you get a cheaper one and end up with a disaster in terms of safety, I suspect. Always read the instructional manual before performing any job. Check the voltage well also.

FAQ’s About AC Vaccum Pumps
What is CFM?
CFM stands for Cubic Per Minute. It is a measurement of velocity at air flows in or out of space. This is normally used for cooling units like AC pumps.
What is different in Stage 1 & Stage 2 vacuum pumps?
The two-stage pump means that it has two rotors and two sets of vanes. If you want a deeper vacuum, you can go for it; otherwise, Single Stage is sufficient. If you area DIY, then a single stage is enough to create up to 75-micron vacuum, and you usually need less than 500 microns what we say an efficient vacuum. Stage 2 can go up to 25 microns.
What is Micron?
It is a unit of measurement from a perfect vacuum. One micron is equal to 1/25,400 of an inch – a linear increment.
How an A/C vacuum pump work for cleaning the HVAC system?
It basically reduces the system’s pressure, and ultimately the water boils at this lower pressure and turns into a gaseous state. After this, it runs from lower pressure to higher demand. We call it suction, but it is not but a push because of the pressure gradient.
What happens if you don’t vacuum your AC system?
You will not get optimal performance if you are not vacuuming before filling out the refrigerant into the system. We reduce the pressure in the system so that any suspended water particles boil away.
What happens if air gets in the AC system?
It traps and reduces the condenser surface area making it less efficient.
What happens if too much oil in the AC system?
It will reduce the cooling efficiency as it will get coated at the inner walls of condenser coils. It will ultimately affect the heat dissipation and eventually down the cooling efficiency.
How many microns is a good vacuum?
It is 500 microns for a complete vacuum in the industry. But some people will do it at a much lower level. The right pump can give you 50-100 micron easily. It is quite a good range for an AC refrigerant.
Can you pull a vacuum with a leak?
No, not at all. By the way, don’t try it.
What are the other uses of vacuum pumps?
You can use it for Milking, food processing, degassing, and Auto AC Refrigerant Recharging.

“Yes, I am a big fan of ‘GOT,’ and winter has come. But honestly said that summarization is scarier than winter if you are not well prepared for it.
I didn’t have any idea about air conditioner vacuum or such a thing even exists, so this is an eye-opener for me. After reading through the post and acquiring some basic knowledge or buying guide of AC vacuum, I would most likely choose the Mastercool 90066-B 6 CFM Single Stage Vacuum Pump.
