The cost of repairing an air conditioning (AC) unit when there is a leak in the house's ductwork or refrigerant lines can vary depending on several factors, including the location and size of the leak, the type of refrigerant used in the system, and the complexity of the repair work.
Here are some general cost estimates for different aspects of the repair:
Leak Detection: Before repairing the leak, the HVAC technician will need to find its location. Leak detection can involve using specialized equipment and may require some labor. The cost for this service could range from $150 to $500.
Sealing Ductwork Leaks: If the leak is in the ductwork, the cost will depend on the extent of the leak and the amount of ductwork that needs sealing. On average, repairing ductwork leaks can cost anywhere from $200 to $1,000.
Refrigerant Leak Repair: If the refrigerant lines are leaking, the cost will depend on the complexity of the repair and the amount of refrigerant that needs to be refilled. Repairing refrigerant lines can range from $200 to $1,500.
Refrigerant Refill: Once the leak is repaired, the HVAC technician will recharge the refrigerant in the AC unit. The cost of refrigerant can vary depending on the type of refrigerant used and the amount required, but it can be anywhere from $50 to $200 per pound of refrigerant.
Keep in mind that these are rough estimates, and actual costs can differ based on your location, the HVAC company you hire, and the specific details of the repair needed. It's essential to get multiple quotes from reputable HVAC professionals to get a more accurate idea of the cost for your specific situation. Additionally, some repairs may be covered under warranty or service contracts, so it's worth checking with the manufacturer or your service provider if you have one.
