Is your window air conditioning system less cold than cold? Don't your air feel as cold as it used to be? Are you aware you can actually recharge and refill your window air conditioner yourself? All these questions and more can actually be answered in this article.
The window air conditioner is built to blow cool air into an office or building. However, when it is not the case, it's probably because of a leak as occurred causing a slow leakage in the refrigerant thereby drastically reducing the efficiency and overall performance of the Window AC cooling system.
To recharge your cooling system, you need some essential tools and materials to effectively recharge it.

- Protective Hand gloves
- Protective eyeshade
- Screwdriver kit
- Leak detector device
- Bullet Valve
- Refrigerant gas (R410a)
- Recharging rubber pipe gauges
1. Detach The Window Ac Unit
It is highly essential to always detach and unplug the unit from its wall socket before you start any work on the window air conditioner unit. Simply unplugging, it is the thing you need to do first to take apart and inspect what's wrong with the unit.
2. Put on protective equipment
If you have decided on fixing the AC unit and recharging it yourself, it is recommended that you wear protective equipment like gloves and clear eyeglasses. The Freon, which is the coolant you will be refilling is highly toxic. It is also cryogenic and can cause frostbite if it gets into raw skin contact. Please, therefore, take all the appropriate precautions.
3. Check For Leaks
There are actually a few ways to check for leaks. Below are various ways to achieve that.
-
Using leak detector
Turn onto the device and cover the outside with direct leakage. Switch the leak detector on and move its sensor close to the external unit of the ac. If there is a leak, the leak detector can give audio or visual (or both) signals, depending on its form.
-
Soap use
Prepare a soap and water mixture. Lubricate the entire transmission equipment for the coolant (valves, pipe etc.), and then turn the system on. If you track the creation of bubbles, you have discovered the leak.
-
Use of fluorescent dye
Newbies may perform this process. It requires the system to be filled with a little fluorescent color and then switched on. The dye then circulates with the coolant and builds up at all leaks. A leak detection lamp or ultraviolet lamp can be used to identify the position of the leak (it will be bright).
-
Usage of nitrogen
Experts can only use this form. It needs the closure of all the valves connected to upstream or downstream equipment, nitrogen strain, initial pressure control and pressure measurement after a few minutes. If there is a considerable reduction in pressure, it means that there is a leak.
4. Locate the leakage and fix it
Immediately you have unplugged the unit, you need to check it thoroughly for the leakage. This can avoid additional problems with your AC. When your AC is already open, it can make a big difference by only checking for any form of leakage or damage within the device. If you find anything wrong, go ahead and fix it or clean it up. Depending on the model types, you might actually have to employ the help of a professional to check it out.
5. Recharge your AC With The Freon Kit
You need to locate the compressor to recharge your AC. You can generally do so with the equipment in the kit you purchased for your AC. It is also recommended to rely on your user manual at this stage Get your service file and connect it to the compressor side. You can now attach the top valve to the other compressor side. Anything with your Freon kit should be given. Freon kits come with a detailed diagram showing you how to connect the two valves Now attach the lines to your freon that you linked to.
Ensure all are linked correctly and that no leakage is possible. Turn your AC unit window on and ramp it to its maximum power level. Now that the service valves and tap valves connect the Freon tank with the air conditioner, the refrigerant starts flowing from the tank into the AC compartment.
Recharge to Specification
It's essential to recharge the right quantity of refrigerant into the cylinder of the AC unit. The environmental protection Agency advise that overcharging systems have higher potential for leakage and undercharging will be less effective.
6. Close and plug back the AC unit
After recharging the AC unit, connect everything tightly and ensure that you close the opening and plug to its wall socket. Turn on your window AC unit and increase it to the highest level. With this, you will be able to determine if you have been able to effectively recharge your window AC unit.
Conclusion
If you are going to be recharging your ac unit without the help of a professional, it is vital to take note of the laws in your country in regards to self-help and adjustment of the AC compactment.you're not breaking any law before embarking on it.
