Air Conditioning Vacuum Pump Operation
In order to remove all the unwanted moisture and gases from the refrigerant system, a state of near vacuum has to be achieved in which the pressure in the system is forced to go below the atmospheric pressure. The absolute value of the atmospheric pressure at sea level is given by 29.9in. Hg or 14.69psia or 759.99mm Hg or 759,99microns.
In the typical system, the vacuum pump is required to create a vacuum state of about 300 to 500 microns. An electronic vacuum gauge is needed to measure the level of vacuum in the system. Check the specifications of the vacuum pump and make sure that it is able to achieve the vacuum state as required by the manufacturers of the equipment.
ZENY 3.CFM Single-Stage Pa Economy Vacuum Pump
This is a single-stage pump designed for HVAC system applications. The pump is driven by 1/hp direct drive motor that provides a quick start while eliminating the need for maintenance. It evacuates air at a rate of 3.CFM and operates at a low noise level ideal for indoor use. The pump has an oil drain feature that faces down for quick and easy drains. A built-in fan comes in handy for long duration operation by keeping the pump from overheating. There’s a sight glass that lets you monitor oil level at a glance. The housing of the pump is of heavy duty aluminum alloy designed for maximum durability. This 3micron pump is quite lightweight weighing at just 11.pounds.
FJC 691Vacuum Pump 5.0 CFM
If you’re looking for speed in a single-stage air conditioning pump, this pump might just work for you. The pump has a 75-micron rating and evacuates air at an impressive rate of CFM. A single-stage 1/hp rotary motor with 172RPM speed provides quiet operation for indoor use. There’s a large refill cap and drain valve to make the process of oil changing much easier. This pump is ideal for evacuating non-condensable gases and comes more affordable compared to other HVAC pumps in its class.
Kozyvacu is a lightweight AC vacuum pump that has been built to last. It is constructed using the lightweight aluminum cast for maximum durability. The pump is made using the direct drive motor allowing for ease starting and maintenance. You can monitor the oil levels and quality through the oil viewing windows. There is also a drain valve at the bottom of the reservoir for faster draining of the oil. The oil fill port makes the addition of oil pretty easy for users. This pump will make a great choice for extended work as it also comes with a built-in high volume cooling fan.

Giovanni Battista Venturi was an 18th-century Italian polymath who did a remarkable number of things extraordinarily well. He was an ordained Catholic priest, a university-level mathematics instructor, one of the leading civil engineers of his day, a politician and statesman (and a favorite of Napoleon Bonaparte), and a world-class historian. In fact, it was Venturi who first called attention to Leonardo da Vinci’s scientific contributions.
Perhaps his greatest impact though, came from his trailblazing research in fluid mechanics. His discovery of the Venturi effect — the eponymous physics phenomenon he was first to describe — is the basis for various important contraptions today, from paint sprayers to fertilizer applicators to gas grills to scuba regulators.
Venturi really didn’t understand the reasons behind this phenomenon, now universally known as the Venturi effect. But it is easily explainable today using the important law of fluid mechanics known as the Bernoulli equation. Without getting into the math, we can state in broad terms that fluids under pressure and moving through a gradually narrowing pipe gain speed. That’s easy enough to understand; since the number of fluid molecules going in and coming out of the pipe is constant, the fluid molecules have to speed up in order to move through the constriction.
Venturi’s insight was that where the fluid speeds up, concurrently the fluid pressure drops. If you measure the pressure at various points in a system of pipes, you’ll find it’s lowest where the speed and pipe constriction are the greatest.
You’ll need an air compressor in order to speed the air through the venturi, and high-pressure air must be handled with caution. Use your compressor in accordance with manufacturer’s directions and wear protective eyewear.
When you draw a vacuum in a container, atmospheric pressure could cause it to implode. For plastic soda bottles, that’s pretty cool. For other items, it’s not so good. If you apply your pump to a glass flask or bottle, be sure it is strong enough to handle an atmospheric vacuum.
Fun with a vacuum pump
What will you do with your vacuum pump? Science! The easiest experiment is to drill a hole in the cap of a plastic soda bottle and insert the hose barb while the pump is running. It’s oddly satisfying to implode bottles and then watch them regain their shape when the vacuum is removed.
Another easy trick is to place a few marshmallows or a dollop of shaving cream inside a vacuum-capable flask or jar. Pull a vacuum and watch what happens to the stuff inside when it’s liberated from atmospheric pressure.
A classic experiment is to place a buzzer inside a container and then evacuate it. The buzzer will go silent or nearly so, since a vacuum can’t propagate sound waves.
I have a JB DV200N but also have a Vacmaster as a back up. Sometimes I have to do a start up for the install crew and run over to get pulling a vac while running my JB vac on my job.
I have had it for many years and works as well as the JB at about 40% less.
It doesn’t have a bank off valve but I just use my Schrader core tool.
Tools of the HVAC Trade
This hub will provide you a list of tools that you will need to begin your HVAC career, along with photos and a brief explanation of their use. I will also give you various names for these tools, so that when your partner says, “Hey rookie, give me those tongs,” you won’t be looking for a salad utensil.
18-volt battery operated drill with two batteries, a charger, and commonly used bits.
All these tools will become your friends, but none of them is as essential in HVAC as the battery operated drill. I suggest 1volts minimum, with two batteries and a charger. Do not spare expense here; a good drill will more than pay for itself over time. The drill will often come with a Phillips bit, but you’ll need to purchase a 1/4″ hex bit as well, as this is the most common type of screw that you’ll be using in HVAC.
No. I didn’t spell it wrong. A sawzall does exactly that. It saws just about anything depending on what blade you put into it. This also is a tool where I wouldn’t suggest sparing expense. Find yourself a durable sawzall that will last. Blades will likely be supplied by your employer. I like a quick-release blade installation, but there are many styles available.
Folding Bar or Drive Bender: This is a simple-looking tool with multiple uses. Each side is slotted (one side is slotted 1″ from the edge, and the other 1/2″) so that sheet metal can be inserted and bent to whatever angle you need. It also comes in handy as a straight edge.
By inserting sheet metal, usually round piping, in the teeth of this tool and squeezing down; you can create a “crimp,” a wrinkled male fitting, to be inserted into the uncrimped female side of another pipe for joining the two together.
Awl or Scratch Awl: The awl is used to puncture round metal piping for the installation of dampers. It is also used to scratch markings on sheet metal.
III. HVAC Tools Used For Air Conditioning Work
The tools are below used to service and install air conditioning systems, though many of them are used in refrigeration as well. Your employer will supply some of these, but you might want to take a look now at the tools you will work with regularly.
A tubing cutter is used to cut the copper lines used in air conditioning systems. It is adjustable to fit various diameters of tubing or piping. Often, a de-burring tool will be built into the back of the cutter. The cutting wheel is tightened down on the copper, the tool is spun around the tubing a few times, then tightened again. This is repeated until the copper is cut where desired. Do not rush this process as you will damage the copper. The de-burring tool then is used to remove any burrs left behind, since these small pieces can cause a system to malfunction if they get into the lines. Cutting wheels will get dull over time, so they are usually replaceable.
Your employer will most likely provide you with a vacuum pump. It is used to suck moisture and air out of air conditioning lines. The lines must be pulled into a vacuum and tested for leaks before the system can be charged with refrigerant.
Blanket: Batt and Roll — The most common type of insulation, it is usually made of fiberglass, though some can be made of wool, natural fibers, plastic, or minerals (rock and slag).
Concrete Blocks — Concrete blocks are used in foundations and are often found in full basements. Insulating the spaces in the blocks is not the way to insulate them as the heat energy will travel along the concrete itself. The best way to insulate with concrete blocks is to use insulated concrete blocks, which have polystyrene incorporated into them.
Foam Board — This is most commonly used for unfinished interior walls. To meet fire safety codes, it must be covered with gypsum board.
Insulating Concrete Forms — Made in board and block forms, these foam elements are incorporated right into the construction of a building.
Loose Fill — This somewhat fluffy-looking insulation is often used to add insulation to an area. It gets sprayed or poured in.
Reflective System — Foil-faced insulation used where downward heat flow is an issue. While you can combine insulation types, foil-faced insulation often requires the foil facing to be removed first.
Rigid Fibrous Insulation — This is fiberglass insulation that has been set into a specific shape, such as being made to fit ducting. It can withstand high heat.
Sprayed Foam Insulation — This insulation is best used by injecting into finished walls or for insulating irregularly spaced areas or going around obstructions.
Structural Insulated Panels — These are sections of wall built with the insulation already inside. Houses built of these panels are so far the most energy-efficient houses around.
Depending on the insulation, you can see a R-value of Rto Rper square inch, though Insulated Concrete Forms can have an R-value of R20.
Electrical Repair Components
Capacitors — Capacitors help your HVAC motor start from a standstill. Over time they can weaken. As they weaken, they cause the motor to run hotter. This can shorten the life expectancy of your motor. Once a capacitor fails, the whole motor will stop working. You usually won’t notice that a capacitor has weakened until your motor stops turning on.
Compressor — Compressors are outdoor components in your system. The compressor is the pump that circulates the refrigerants through the air-conditioner. You can hear it when it’s running so you’ll know if it’s working just by listening. If it starts getting louder, your compressor is about to fail. If it makes no sound when it should be on, it has already failed. Compressors fail for a number of reasons. Most often they fail due to strain from another failed part such as the fan motor. Electrical storms can also damage compressors. If the sound from the compressor gets louder or if you see a decrease in performance, you should have your compressor checked. A failed compressor will not heat or cool your house.
Contact/Relay — Relays are electronically controlled switches that activate the various components of your HVAC system. They manage everything from the power going to the motor to automatic dampers, humidifiers, etc. Most of them are controlled by the thermostat. The most common failure for a relay is being stuck in the “open” position. Separated from its assigned contact point, it fails to complete the connection and send the message to whatever it was supposed to operate. This failure usually occurs from use over time. Each time a relay connects and sends its signal, the electrical arcing from point to point eventually causes wear and tear.
Furnace Circuit Board — The furnace circuit board controls a variety of functions. It not only handles the regular operation of the furnace, it also monitors the furnace’s various safety circuits. Over time, vibrations from the furnace can weaken solder point and cause them to separate. Dirt and debris can cause short-circuits that damage the board. Failure of the circuit board can cause a variety of effects ranging from the fan not turning on to the complete shutdown of the furnace.
Fuses — Anyone who has worked with electrical systems knows all about fuses and how they fail. They can burn out over time, may just be loose, or can blow out during an electrical storm or due to overload from another failed component. Of course, that’s what they’re supposed to do; they stop surges from going through and damaging the rest of the system. When a fuse fails, whatever system it was protecting will stop working.
Gas Valves — On a gas furnace, a gas valve can become stuck due to dirt or debris building up after sitting idle all summer. A gas valve that is stuck closed will provide no heat.
Indoor Fan Motor — Indoor fans circulate the air from your house and through the system. Age and dust buildup are the two biggest contributing factors to their failure. When they are starting to fail they will often make noise. Failure of the fan will result in no heating or cooling, and if it is not repaired soon, it can cause other components to fail.
Outdoor Fan Motor — The outdoor fan, also called the condenser fan, is exposed to external conditions. As such it is most prone to dust and debris and the extreme weather. In desert climates, the outdoor fan motor is subject to heat not only from normal operation but from the outside temperature as well. As it starts to fail, the fan may work fine in the cooler morning hours but stop by afternoon. This can shut down the entire system for hours. When they stop running completely, your air conditioner will no longer work. Running a faulty fan will lead to compressor failure, which is a very costly repair.
Pipe Repair Areas
Drain Lines — Dirt, debris, and hard water can build up in your drain lines and cause the drain pan to overflow. Drain lines rarely give any kind of warning that they are blocked. They should be cleaned annually to prevent water damage from overflow.
Outdoor Coil — The outdoor coil is similar to the indoor coil except that it deals with the outside air, using it to absorb heat from the coil. It can suffer the same problems as an indoor coil. The difference is that since the refrigerant is under high pressure, even a small leak can lead to a complete loss of air-cooling ability.
Refrigerant Metering Device — Every HVAC system has one of these, and heat pumps have two. They regulate the amount of refrigerant going through your air-conditioner. If it fails, either too much or too little refrigerant will course along the lines and either not perform well or will overwhelm the compressor and cause it to fail. A total failure of this component will result in a complete loss of operation.
Restriction — Any kind of blockage anywhere in your system will lead to reduced performance or failure altogether. Filters can get clogged and need replacing, or a filter may have failed to block debris from getting through. Some filters are replaceable quite easily while others may need a little more work.
Reversing Valve — The reversing valve is what allows your system to go from cooling to heating and back again. If this valve gets stuck in one position it will not be able to switch to the other mode. If it fails midway between the two, your system will not function at all. Debris is usually culprit for these valves sticking.
Some of these components can be repaired or replaced by the homeowner, such as filters, fuses, and clogged up drain lines. Coils, compressors and the other components are best left to a professional. In some cases, you may have a system that is so old that parts are no longer available or else they aren’t up to code. In this case you will have to consider replacing the entire system.
Beginnings of an Industry Revolution
To accomplish the goal inherent in the title of “vacuum” the cleaning unit must create suction for the purpose of sucking up debris and dust from a given surface, usually flat. 30 years after Ives McGaffey invented his “Sweeping Machine” in 1889, the first motorized vacuum cleaner was invented by John Thurman. His invention was patented in the same year and was the first to use gasoline to power a motor, for the purpose of creating suction with which to clean dust and debris from the home. By 1903, Thurman had started his own door-to-door floor cleaning company, located in St. Louis.
The Birth of Hoover Handheld Vacuums
As a department store janitor, in Canton, Ohio, James Spangler would often use a sweeping machine to clean the department store floors after closing. The sweeper would spew more dust into the air than it captured and so Spangler developed an incessantly chronic cough. The thought occurred to him that perhaps the sweeper dust and the cough were correlated and set about fixing the problem.
In the same year, Hoover also introduced an additional design element to the Hoover Vacuum engineering with the beater bar. Hoover’s beater bar, worked as a complementary feature to the suction power of the unit, guiding dust, and debris into the vacuums area of most suction. This innovation sparked Hoover’s trademarked slogan with, “Hoover. It beats, as it sweeps, as it cleans.” By the mid-1950s, the Hoover slogan was adapted into a jingle, which became as recognizable as KitKats, “Give me a break, give me a break. Break me off a piece of that KitKat Bar.” The Hoover vacuum cleaner had become a guide to the industry standard for vacuum cleaner buyers everywhere.
Hoover vacuums and appliances welcomed facets of their home.
The Future of Hoover
In recent years, Hoover has seen a change in direction, from branding themselves through the classic vacuum cleaner image to rebranding themselves with a high-tech, cutting-edge flare. Currently, the company is guiding buyers to Hoover Vacuums of the future. Their focuses have taken on an undertone of technological advancement and the company is innovating new ways to incorporate emerging technologies with tried and true engineering.
The future of the Hoover Vacuum Cleaner Company brand will depend largely on the ability of the company to push the boundaries in their research and technological innovations, which they are embarking in today. Hoover has come to market with several products, under their vacuum cleaner and floor cleaner line, which are some of the best Hoover vacuums that have ever been made in the history of the company.
Hoover has inducted several new additions to its product line since its TTI acquisition in 2007, which have broken new ground in the home floor cleaning appliance industry. The most notable of which, are the ones that transcend the conventional ideologies concerning the limitations of home appliance technology integration. The automation of manufacturing has foreshadowed an emerging market of automated home appliances and Hoover is a trailblazer in the field of vacuums.
