What Is the Best Vacuum Pump for Your HVAC?

One of the most important tools to have when servicing an AC unit is the AC vacuum pump. This pump allows you to remove moisture from the system before AC service and repair.

Because of how many HVAC vacuum pumps are on the market, it can be difficult to know which is the best HVAC pump.

In this article, we will discuss recommendations for the best HVAC vacuum pump for homeowners and professionals alike. We will also cover some important factors you need to consider during the purchasing journey.

What Is the Best Vacuum Pump for HVAC? 

If you need a vacuum pump for HVAC equipment in your own home, you likely need an air pump that is affordable, easy to use, and reliable. However, you don’t need the best vacuum pumps for HVAC professionals since these models are often much more expensive and powerful than homeowners need.

As a result, you should look for devices that are still reliable and get the job done without costing a fortune. Two of the most popular HVAC vacuum pumps are the Zeny AC vacuum pump and the FJC 6912 Vacuum Pump. Let’s take a closer look at each one. 

Zeny AC Vacuum Pump 

The best vacuum pump for HVAC will depend on a person’s unique needs, but the Zeny AC Vacuum Pump is among the best for homeowners. This vacuum pump is highly affordable but still offers great value and comes with a 30-day warranty.

This vacuum pump offers great capabilities too. It has a power rating of 1/4 horsepower, which is very impressive at its price point. It even offers a 3.5 CFM airflow rating, which is more than enough for the majority of HVAC air pump users.

The base on this pump is impressive as well. It is both shockproof and wearable. This adds a little extra cushion and care for the HVAC pump. 

FJC 6912 Vacuum Pump

The FJC 6912 Vacuum Pump is another good purchase for homeowners. It is both affordable and reliable. It is a good choice if you just need a starter unit or a backup. One benefit of the FJC 6912 Vacuum Pump is that it is very quiet. This quiet sound means you don’t have to worry about waking up the whole house if you need to use this pump.

When compared to the Zeny, this pump isn’t quite as fast.

Nevertheless, the FJC 6912 Vacuum Pump is a good pick, especially if you need an AC vacuum that is very quiet.

What Is the Best Vacuum Pump for HVAC Professionals? 

Although the Zeny AC Vacuum Pump is a great purchase for homeowners, it isn’t necessarily the best pick for HVAC professionals. The same is true of the FJC.

HVAC professionals need highly effective vacuum pumps that are durable and long-lasting. As a result, we recommend something a bit sturdier if you are a professional, like the Fieldpiece.

Fieldpiece Vp85 Two Stage Vacuum Pump 

The Fieldpiece Vp85 Two Stage Vacuum Pump is highly effective and durable, making it a great choice for professionals.

For starters, this AC vacuum pump has a variable-speed DC motor. This allows the device to remove any air and moisture at some of the fastest speeds. Additionally, changing the oil is super fast and can even happen when the vacuum is running.

Something else that’s fantastic about this AC vacuum pump for professionals is that it is compatible with multiple-sized hose lines, including 1/4 inch, 3/8 inch, and 1/2 inch. For professionals, this versatility is a major plus.

All the while, the Fieldpiece Vp85 Two Stage Vacuum Pump is completely durable. The material itself is water-resistant and can even withstand rain. This allows you to vacuum out the AC system, even if it is located outside during the rain.

Factors to Consider When Buying the Best HVAC Vacuum Pump 

Whether you need an AC vacuum pump for personal use or professional use, it’s imperative that you select your model carefully. There are two factors you especially need to consider: CFM and stages. These two factors will help you select the best HVAC vacuum pump for your needs.

CFM 

CFM stands for cubic per minute. The number tells you how fast the device can pump out air. The higher the CFM, the faster the device works. If you only need a residential HVAC unit, a 2 to 5 CFM works fine, but professionals may need a CFM rating above 5.

Stage 

HVAC vacuum pumps are either one-stage or two-stage devices. Two-stage devices are the most effective, but they are more expensive. As a result, most residential users opt for a one-stage vacuum. This will get the job done, but it will take a bit more time. Professionals prefer two-stage vacuum pumps since they work faster.

Conclusion 

Regardless of whether you select an HVAC vacuum pump from our list or elsewhere, remember to consider the CFM and stage first. These two factors will help you to determine if the vacuum pump you are looking at meets the power requirements you need. Additionally, make sure to read reviews to make sure that the pump actually lives up to its description.
