Steps to Follow

Prepare the Area

Ensure the area around the air conditioner is clear and safe to work in. Turn off the power to the unit at the circuit breaker. This precaution is vital to prevent any electrical hazards during work.

Locate the Service Valve

Identify the service valves on the air conditioning unit. There are usually two: the high-pressure and low-pressure service valves.

Use a Refrigerant Recovery Machine

If you have access to a refrigerant recovery machine, connect it to the service valves. This machine will safely extract the refrigerant from the unit into a recovery tank. This is the most effective way to avoid releasing refrigerant into the atmosphere.

Recover the Refrigerant

Open both service valves slowly to allow the refrigerant to flow into the recovery machine. Monitor the pressure gauges and follow the manufacturer's instructions for the recovery machine.

Cap the Service Valves

Once all refrigerant is recovered, close the service valves and cap them to prevent contamination and loss of refrigerant.

Disconnect the Lines

Carefully disconnect the refrigerant lines from the unit. Use a wrench to loosen the connections and be prepared for any residual refrigerant that may escape.

Remove the Air Conditioner

With the refrigerant lines disconnected, you can now remove the air conditioner from its mounting. Ensure to follow any additional manufacturer-specific instructions.

Seal Openings

After removal, seal any openings in the ductwork or wall to prevent drafts or pests from entering.

Disposal
