Before recharge home ac, one should conduct simple maintenance on the AC. Begin by cleaning the condenser coils and evaporator to ensure proper operation. Build up in these areas can cause the conditioner to operate in the wrong way or even cause damage. Blower fans should always be clean; therefore, looking for debris in the fan is an essential step.

Type of refrigerant and Recharging system

The operating guide is often found at the control box or the air handler. The type of refrigerant compatible with the conditioner can also be indicated at the AC’s cabinet. A quick search online can also help to identify the right coolant and recharging system. Some systems have a quick connection that allows for a refill without losing existing Freon. It is essential that Freon is handled with care as contact with the skin can cause injuries.

Taking precautions when making a refrigerant change is essential. The first precaution is to make sure that the system is completely turned off and no power is in the system. Making sure power is cut off at the circuit breaker and the fuses removed is one of the best ways to make sure that there is no power to the air conditioner.

One should then hook up the gauges as per instructions. Gauges indicate low pressure while the side of the system should be high pressure. After connecting the gauges, turn on the AC for about 15 minutes for system stabilization. The blue gauges help to identify whether there is a need for a refill or not. If the blue gauge drops after stabilization, then this is a sign that a recharge is needed. The sight glass is another method to confirm whether there is a need for a recharge. If there are bubbles, then the refrigerant needs a recharge.

Filling Air Conditioner Refrigerant

After confirmation, one needs to shut down the unit. Carefully connect the manifold hoses to the ports. The low-pressure hose is usually blue color and the other red. After connection, the unit should be turned on allowed to run for another 15 minutes. The Freon container should be connected to the valves, and the air conditioner will take in the Freon automatically. After the recharge, if refrigerant, turn the unit to its highest settings. This forces the Freon to move through the conditioner. After Freon has been refilled, remove the Freon charger. Once this whole process has been completed, the AC should work more effectively at cooling. Now You can recharge home ac by yourself.
