Having issues with your air conditioner in your car or truck? If your thinking about repairing the issues yourself, check out the top 10 best car air conditioning tools and equipment of 2020 below before you get started!
10. FJC Stop Leak – 3 Ounce
It contains O ring conditioners to help seal your car’s air conditioning system to prevent future leaks from happening. There is also red visual dye so that in the event that your refrigerant is leaking out, you’ll clearly be able to see where the leak is originating.
This additive should not harm your refrigerant recovery, refrigerant charging, or your car’s air conditioning system.
9. Mofeez A/C Diagnostic Manifold Gauge Set For R134A R12 R22 Refrigerants, with Couplers and ACME Adapter
The Diagnostic Manifold Freon Gauge Set by Mofeez contains a three-way set of valves with gauges to monitor low and high pressure, a refrigerant can tap valve, two quick-connect couplers for low and high side, and an adapter for ¼” male to ½” female. Also included is a hard red carrying case and 3 color-coded 36 inch (1.2m) long hoses with ¼” flare fittings that come standard.
There is a viewing port so you can confirm that refrigerant is travelling through the hose. It appears that this manifold gauge set does not appear to have a bleed valve so you can safely clear air out of the line to the refrigerant can.
If you’re attempting to recharge, evacuate, diagnose, or repair your car’s air conditioning, you’ll also want to purchase a vacuum pump adapter as well as a vacuum pump with his manifold gauge set. If you’re planning on refilling your tank, you will also likely want to add the proper amount of air conditioning lubricant and U/V dye when recharging your system. Without any lubricant, your air conditioning compressor may lock up and fail to keep working.
8. OrionMotorTech R134A Can Tap Valve Refrigerant Dispenser Tool with Tank Adapter for 1/4 and 1/2 inch AC Freon Charging Hose
One of the most overlooked pieces when it comes to working on recharging your own A/C, the Refrigerant Can Tap Valve from OrionMotorTech comes with an additional adapter to fit both ¼” and ½” threads. Constructed out of heavy duty brass, this can tap valve is sometimes not included with manifold gauges or vacuum pumps and must be purchased separately.
Due to its importance when recharging your A/C and high quality materials, this is on our list for the best tools and equipment for working on your car’s air conditioning.
If you have a ½” Female Port Hose that you need to connect to the refrigerant can, simply add the ¼” Female to ½” Male Adapter and you’re all set. Orion Motor Tech stands by their products, and if you experience any problems with this adapter, they’ll happily work with you to resolve your problems.
7. ZENY 3.5CFM 1/4HP Single-Stage Vacuum Pump
The Single Stage Rotary Vane Vacuum Pump from ZENY comes in a nice blue color and offers 3.5 CFM (Cubic Feet per Minute). This HVAC Air Tool has a ¼” Flare Inlet Port for connections and operates with ¼ HP. The copper core motor provides stable operation and should have long-term durability as a result.
This vacuum pump is effective and fairly quiet. It comes with a manual and a bottle of vacuum pump oil, which may not be very good quality. If you intend on using this frequently, you may opt for getting a different pump oil to match. Be on the lookout for any potential oil leaks, but expect to see a little oil smoke during operation. This seems to be normal for vacuum pumps.
This would make a great addition for any garage tool set, especially if you need to recharge your car’s A/C or just evacuate the system of any moisture. This can also be used around the house for wine degassing, food storage prep, medical uses, and more.
6. OrionMotorTech 5FT AC Gauge Set for R134A R12, R22, R502 Refrigerants, with Couplers and Can Tap
This set of AC Manifold Gauges by OrionMotorTech is an incredibly cheap option that will get the job done. The 3-way diagnostic manifold gauge set can be used for diagnostic checks, evacuation (vacuum), freon charging and recovery work with refrigerants R134A, R12, R22, and R502. It includes three 5ft long hoses that are color coded for your convenience. The yellow hose is for your vacuum pump and refrigerant can connections, blue is for low pressure and red is for high pressure.
This set comes with a 3-way HAVC freon gauge (¼” male), 3 pc hoses (¼ inch female), 2 pc quick couplers (¼ inch male), 1pc can tap (¼ inch male), and an ACME adapter (¼ inch male to ½ inch female).
One downside of this manifold gauge set is that it does not include a bleed valve in order to evacuate the air out before charging your AC. In addition, the hoses don’t appear to have quick connect fittings so you may need to tighten the connections with tools in order to secure them properly.
5. Kozyvacu Single-Stage Rotary Vane Vacuum Pump for HVAC/Auto AC Refrigerant Recharging
The Single-Stage Rotary Vane Vacuum Pump from Kozyvacu is intended for uses like refrigerant recharging, milking, medical uses, food processing and refrigerant recharging. It has a ¼ HP thermally protected motor with an air flow measurement of 3.5 CFM (Cubic Feet per Minute). V: 120AC, HZ: 60
It is constructed out of lightweight cast aluminum which makes it quite durable. There is an oil drain valve for easy removal of oil and an easy fill port that allows for adding from the front or either side. There is a high volume cooling fan built-in to extend the life of this motor. The motor is a direct drive motor which will start easily and is considered maintenance free.
4. XtremepowerUS 3CFM 1/4HP Air Vacuum Pump HVAC R134a R12 R22 R410a A/C Refrigeration Kit AC Manifold Gauge with Carrying Tote
If you’re looking to recharge, diagnose, or repair your AC system to get cold air flowing through your vents again, this Car A/C Refrigeration Kit includes most of the things you’ll need to get started. It features a set of manifold gauges, a vacuum pump, a bottle of vacuum pump oil, quick disconnect couplers for high/low, a few adapters, and color-coded 36” hoses for low pressure, high pressure, and refrigerant lines. It even includes a convenient storage bag to keep all of this equipment clean, dry, dust-free, and kept in the same place.
The vacuum pump is made out of aluminum alloy, allowing it to be durable and still lightweight. There are two options for the vacuum pump available, 3CFM 1/4HP or 4CFM 1/3HP. Either way, the vacuum pumps are quiet and have been designed for efficiency and proper cooling to ensure they will last for extended periods of use.
Tethered safety caps made of brass will ensure oil won’t leak during transport. There’s an oil drain plug to drain the oil, and an oil fill port on top that will provide a clean pour. The pump will only require about 75% of the bottle that is provided, so be careful not to overfill it.
The gauges themselves are ideal for R12, R22, R134a and R410a and will allow you to diagnose and repair your AC system. There is an air release valve for the refrigerant line so that no unwanted air gets circulated into your refrigerant system.
The one thing we noticed that was missing from this kit is a can tap adapter, so you will most likely need to buy one of those if you’re planning on using this with small cans of refrigerant.
3. OrionMotorTech Adjustable R134A Adapter Fittings, Quick Coupler Links, For High & Low AC, Conversion Kit, 1/4″ SAE
The adjustable adapter fittings from OrionMotorTech are just what you need in order to convert a manifold gauge set to have quick connect fittings. The knurled grip ring allows for an accurate snap on lock that will confirm your connection is secured properly.
Included are two rotatable and detachable adapters for ¼ inch SAE that will work great to convert old R12 Gauges over to 134A or replace old, worn out service couplings.. These adapters are comprised of several materials. The ACME adapter is made of bronze, the switch is made of aluminum, and the body is nickel plated bronze.
This Air Conditioner Vacuum Port Adapter from Pioneer will convert 5/16 inch SAE charging vacuum ports with the gauge-hose sets that are ¼ “ SAE. This is useful for most R410A Ductless Mini Split Systems that are newer. This adapter is constructed of heavy duty brass, and features a full swivel tip. One end is 5/16” Female SAE and the other end is ¼” Male SAE. The female end should feature a Schrader valve. This adapter helps to convert R410a style 5/16 SAE service ports so that they can be compatible with older 1/4 SAE gauge hoses.
This is a replacement for the Yellow Jacket 19173 and is necessary for Pioneer mini-split systems that have 5/16” SAE service ports. When connecting this adapter, it is suggested to hand-tighten and then use pliers to slightly firm the connection, but be careful not to overtighten as overtightening the adapter will cause the gaskets to fail. If you end up breaking one of the gaskets, this may mean that your efforts to vacuum pump your system will fail.
1. FJC 6014 Vacuum Pump Adapter
This Vacuum Pump Adapter offered by FJC is compact and solid brass, offering a ¼ inch flare female connection on one end and ½ inch Acme male connection on the other. This adapter will allow you to connect a ½ inch Acme R134A hose to a vacuum pump by way of the ¼ inch service port. This product is unfortunately not available for sale to the state of California.
The quality on this adapter is exceptional, and if you’re looking for a simple taper adapter, this is one of your best choices. If your vacuum pump has a ¼ inch connection, you most likely will need this adapter.
Please note that there is no Schrader valve inside of this. It is a hollow straight through fitting which may not be compatible with some newer 134A manifold hose sets as they require a check valve that must be engaged in order to flow vacuum or refrigerant.
