Happy sunday
Happy Easter broda.

Let me use this medium to thank you for saving me from spending a huge sum of money dis Easter.

Ma car a/c suddenly stopped working. It was just blinking d green light,nt cooling at all.my car a/c repairer checked n told me ma compressor n condenser is bad.
I ran to dis forum as usual thinking abt 100k to spend to make ma car a/c work again n I saw Mobus fone no n I called him to explain to him.

He ran some checks on d car thru fone because am based in d east . I sent him som fotos n video of d state of d compressor.
He told me to give d fone to ma a/c man n even ma rewire n he told dem wot to do.

In summary, I spent just 10k instead of d list of abt 100k to change d compressor, change d condenser n some other things.

Anytime am in Lagos, I will come to pay Mobus a courtesy visit at his workshop.

Thank you n God bless.

@Mosbus. Thank you very much for the other day. I am the man that came to your workshop with 2006 Rav4 on the 6th of this month, to seek for advice on the installed manual compressor. I put on the AC yesterday 16/4/17, it was blowing hot air. Could it be because the car was idle? I am presently in Osogbo where the compressor was installed and I will go to the AC technician tomorrow to remove the compressor. Thanks again.

SIGNS TO KNOW IF YOUR AUTOMOBILE AIR CONDITIONING EXPANSION VALVE IS BAD.

We've had expansion valves stoped working on the road and doesn't show any sign of problems in the workshop.what's worse an expansion valve can stick closed,stick open,or hang somewhere in between.
Of all the experience seen over years,are those that stick closed are most common.
The gauge will show low suction side pressure lower than high Side pressure.the low side May even draw into a vacuum.
This fault can only be detected with a manifold guage.
For any more enquiries pls contact mosbus cool on 08026941215 or 08037586148

Hello Mobus,
I was the one that came with baby boy last Saturday to repair my AC. Thanks for the wonderful job.I'm really enjoying the AC now.

I really love your hospitality and professionalism in the field. There is no doubt about it you are a guru unlike some AC technicians who will be doing trial by error on your AC.

I won't hesitate to recommend anyone who has AC issue to this guy. I see him as a learned and he has computerized equipment to diagnose your AC system.

Weldone Mobus.

Always Make you clean your cabin filter at least every 3 months.
How to identify that your cabin filter is clog.
1,When ever you regulate your fan speed to num 2-3 and you don't fill the air touching you but when you put the fan to the highest speed then you start fill the air pls check your cabin filter.
2,when people at the back seat is complaining of heat in the car but people sitting at the front seat is filling cold pls check your cabin filter.
Fill free to contact mosbus if you have any issues with you automobile air conditioning.

Just changed a client evaporator.
what causes the damage is Lack of dusting is cabin filter.
Pls Always do preventive maintenance on your car.
Cleaning of cabin filter won't cost you any thing.

your gas level is low or check your heater regulating switch if you mistakenly increase the temperature.

The switches are low on both sides so definately, my gas is low. How does vacuuming the ac system work? I have done ac refill before and they never vacuumed for me.

your car has leakage pls check for leakage before refilling.
Vacuuming a system helps your car to take the right amount of gas when refilling.
If you don't vacuum before refilling,they are some trapped air inside the system and by definition air occupy space. So the right quantity of gas that is supposed to go Inside the system won't go in that is why most technician refill excess of gas inside your car.

Have you ever lifted the hood of your car and noticed a label calling out specifications for your mobile A/C system? Did you ever wonder why it was there?

Your car’s manufacturer put that label in the engine compartment in compliance with a standard set by SAE International. It is SAE “J” standard 639.The label is also required by some regulatory state and federal authorities.

Avoid removing this label from your car.

Look closely at the label photograph above. Notice the label recommends professional service for the air conditioning system. There are two basic reasons for professional service, first a personal safety concern as the system is under pressure and can cause injury and second the refrigerant charge and refrigerant lubricant amount are critical to system performance.

Notice it identifies the refrigerant in this particular vehicle as HFC-134a and tells the service professional the refrigerant capacity in both ounces and grams. It also calls out the plus (+), minus (-) tolerance, this means the system will still function properly within this range of over/under refrigerant charge.

Look to the far right of the label, in this column the type of compressor lubricant is called out for the service technician so he knows exactly what type and how much to add to the system.

It has filter,the filter in your car is a net type,but if the filter has been removed and the same problem still persist that means your evaporator is dirty.
