Your air conditioner requires gas to transport heat from the inside to the outside atmosphere. The refrigerant is a low-pressure gas that transforms into liquid and then back to gas in a continuous cyclic process. Copper coils contain refrigerant gas. The heat in the air will be absorbed by the refrigerant and the coils. During this process, the refrigerant gas transforms into a liquid to aid in heat transmission and exchange.
Do you know how your air conditioner keeps the room cool? Everything happens as a result of the refrigerant gas used in the air conditioner. Your air conditioner will not work efficiently if the refrigerant is either too much or too little. There are numerous AC gases that can be used as refrigerants. Here is a quick start guide to AC gas filling or topping off.
AC gas classifications
R22, R410A, and R32 are the most common refrigerant gases used in air conditioner gas refilling. R290 (propane) and R600A are two environmentally friendly refrigerants on the market (Floron).
How frequently should AC gas be refilled?
When your air conditioner is working properly but not efficiently cooling your room, warm air is coming from the vents, or ice is forming on the evaporator coil, it is time to refill the gas. The most common misconception is that the refrigerant, like fuel in other appliances, will deplete over time. The need for air conditioner gas refilling is primarily due to a refrigerant line leak.
AC gas filling machine
The following equipment is required for AC gas filling and is typically carried by all AC technicians.
- Air Vacuum Pump Compressor
- Gauge Meter
- AC Gas (Floron)
The method for filling AC gas
Perform each and every necessary maintenance before filling the AC gas, including cleaning the coils and removing debris. If you initiate refilling before this step, the system may be damaged.
Turn off the air conditioner at the thermostat, then remove the plugs and turn off the breaker. Attach the gauges next. The gauges will consist of a moderate side and the system will have a high-pressure side.
Turn on the air conditioner and wait for the temperature to remain stable. Take a reading from the gauges once the system has stabilized. If the readings in the blue gauge fall below its specifications, the system must be recharged. The sight glass on the unit can be used to evaluate the requirement for refilling.
Connect the manifold’s yellow hose to the refrigerant container. To avoid damage, keep the container upright at all times. Loosen the yellow hose and open the cylinder knob for 1 second before tightening it again. This will remove any air that may be present inside the pipes.
Gradually add small amounts of refrigerant into the suction line, allowing the system to settle between inclusions. Examine the temperature and other required readings to ensure that the amount of refrigerant used is adequate.
Close the manifold valve and the knob on the refrigerant tank. Remove the blue suction line hose and the yellow refrigerant tank hose.
Proper care must be taken while filling the gas in your air conditioner since even a simple mistake can damage it.
