When replacement of a damaged A/C compressor takes place, the air conditioner has to be flushed to remove harmful remains like metallic chips, dirty oil and dye. Nevertheless a lot of workshops neglect this mandatory work because of additional efforts.

VEMO has analysed this problem and developed a method to flush the A/C circuit easily. With the new flushing supply set this is done cost-effectively, with less work and, above all, without any residues of flushing agents in the system.

Here we look at the process involved:

Step 1Before starting work at the air conditioner, check the flow direction. Principally it should be in the following order: compressor, condenser, drier, expansion valve, evaporator or compressor, condenser, orifice tube, evaporator, accumulator .

Step 2Recover the refrigerant from the air conditioner and remove the compressor and drier .

Step 3Prepare the VEMO air conditioner flushing supply set V99-18-0067 by installing valve, hose and flush gun on the can. Inject the flushing agent with the pressure in the can. Flush against the flow direction.

Step 4Follow the flush with compressed nitrogen or pressurised air to increase mass flow for maximum cleaning to finally exit the system with the dirt.

Step 6VEMO recommends installing an in-line filter to avoid problems with residues which are left in the system as a hazard. Pull a vacuum after assembly to remove any residual solvent. The line set is clean and ready for service.

    Growing An Air Conditioning Company

    I want to circle back to marketing and advertising to grow an air conditioning company. Customers move, young people buy their first home, and companies need to always be growing. Theres nothing wrong with marketing and advertising to acquire new customers. Heck, its my responsibility to my team to make sure they work every day to earn a living. Even this blog is a form of marketing.

    However, like I said, Phoenix is huge and people need air conditioning in the desert. A good air conditioning contractor doesnt need to use phone solicitors to grow his or her business. Best Buy doesnt have phone solicitors calling to maintenance your computer or TV. But, how many Best Buy commercials, and advertisements have you seen this month a lot right? Thats because they want you to find them when you do need a computer or television!

    My experience has taught me that the AC companies in Phoenix that use these tactics are not the good guys. They offer a low price special and have someone in your area so they can come sell you stuff. In many cases, such as the one this article is about, theyre selling you snake oil.

    Sometimes, the scammers are caught. Unfortunately, most are not. You dont have to dig too deep to see some whove been caught preying on homeowners in recent years. Heres two recent examples:

    Most automakers including Toyota recommends the replacement of the condenser and

    Hoses instead of flushing in case of contamination.

    Two auto manufacturers that recommend condenser flushing are GM and Ford. GM suggests the use of only R-134a for the process. They also want you to do it in a recharging machine to reduce refrigerant loss. On the other hand, Ford approves of using, VSL338 terpene-based solvent for the flushing.

    Here are several methods of how to flush the AC system

    After the compressor failure.

    Remember that you have to flush nothing else

    But the condenser, hoses, and evaporator.


    What Is An Ac Flush

    Car Air Conditioner System Flush Kit AC Flush Kit

    An AC flush, in simple terms, is the act of using compressed air to send a solution through the AC system, which cleanses and grabs any contaminants and particles, and flushes them out of the system. An AC flush is only performed when the system is opened, or when a major component like the AC compressor is changed out.

    While doing this may seem simple, the practice is often overlooked or skipped by DIYers, which can cause a myriad of problems if contaminants are in the system. When done properly, the evaporator, condenser, and AC lines are all properly flushed clean, while the compressor and accumulator / receiver drier are changed.

    How Does A Cars Ventilation System Work

    The automotive ventilation system consists of the air conditioning and heating units all in one. Air gets pulled into the large duct located at the front of the vehicle while the car is moving. When the air enters, it gets heated or cooled, depending on the fan setting you have chosen.

    Heating vs. cooling isnt much different. When the heat setting is chosen, the air moves through the water-heated radiator while the fans push the air into the car. However, for cooling to occur, the refrigerant must be present in the AC system. This refrigerant gas gets compressed and converted to a liquid that moves through the condenser to remove heat. This process creates the cold air that gets pumped into the cabin.

    Why And When To Flush

    It is always necessary to lubricate the AC compressor. The AC compressor is the only moving part in the entire system and the only reason for oil in the system. The oil is being circulated throughout the system, that means that all the components have some coating of oil internally. If any dirt, debris or contamination enters in the system, all components are affected. Cleaning the oil will avoid all of the contamination from the AC system. Remove the old oil remove the contamination!

    Always flush the AC system whenever you replace or remove the AC compressor, or whenever there is any contamination in the system. Every time remove and inspect the orifice tube. From the orifice tube, you can see the AC systems condition. If you see any debris on the orifice tube should cause you to look for other indications of contamination.

    Time To Flush The Condenser

    Begin by finding the high-side inlet which is located somewhere on the condenser. After you have found it, start pouring alcohol carefully into the component through this particular hole. After this, you need to apply compressed air into the hole.

    You need to keep pressurizing the condenser until there are no traces or pieces of contaminants and debris in the solvent.

    No one wants to leave a mess behind so try to catch the alcohol that spills or misses the high-side inlet hole or as it finds its way through the condensers outlet hole. Keep a clean rag near you at all times.

    You can also catch and throw the dirty flushed-out alcohol with the help of a hose that would be connected to the exit hole of the component and falls into a container or bucket.

    Can You Use Mineral Spirits To Flush The Ac System

    Mineral spirits do not evaporate easily because the content has a high boiling point, and this might cause residue to remain on your AC components. Also, mineral spirits may leave residue in essential AC components that can cause severe damage to your AC system. They are highly flammable, so you must use them with care. Therefore original equipment manufacturers do not recommend using mineral spirits for flushing AC systems. You may void your warranty if you go ahead to use it.

    If An Air Conditioning Company Youve Never Done Business With Solicits You Over The Phone Hang Up

    How To Flush Ac System

    Let me explain: Phoenix alone is the 6thmost populous city in the country. Cities like Mesa & Glendale are in the top 50 largest cities in the US. Frankly, this is the desert practically every home in the Greater Phoenix area has central air conditioning. Theres no shortage of customers or work for a well-run air conditioning company in Phoenix.

    If an air conditioning contractor near Phoenix needs to run a call center to solicit business from strangers, beware! Any honest, reliable HVAC company in Arizona should have more than enough business to not need an outbound phone center. If they do need to cold-call to get calls, theres probably a very good reason, and its probably not good.

    Dont get me wrong. If youve done business with an AC company previously & they call you to remind you its maintenance time, thats great. I would go far as saying thats good service its easy to forget your AC unit until theres a problem. However, we all get enough spam and robocalls from scammers already, & theres a reason they earned the name scammers! Traditional marketing and advertising should be more than enough for any good business to acquire new customers.
