Refrigerant leak diagnosis & repair

Understand the cause and the scope

Low performance alone does not prove a leak. Airflow and other operating conditions must be considered. Once a leak is confirmed, the location and component condition guide the repair options. The refrigerant type must match the equipment; different refrigerants are not interchangeable.

Make a confident decision

Ask what leak detection, repair, testing, and refrigerant are included. For an older system, compare the repair with replacement instead of assuming repeated additions are the least expensive long-term path. Keep previous invoices so the history is available.

Built for Gulf Coast conditions

Southwest Louisiana systems work through long cooling seasons, high humidity, salt-influenced air, storms and heavy rainfall. The recommendation should consider drainage, corrosion exposure, airflow and recovery after outages—not equipment capacity alone.

Equipment and registration

S&S is a Carrier - Tempstar Elite Dealer and an approved Trane Dealer. Ask which brand and model fit the project. Manufacturer registration controls eligibility for extended parts coverage. S&S submits registration where possible; the customer should retain and check the manufacturer confirmation. The manufacturer’s written eligibility and warranty terms control.

Parts coverage and workmanship coverage

Manufacturer parts coverage and S&S workmanship coverage are separate. A manufacturer parts warranty covers the part only; diagnostic labor, refrigerant, freight and miscellaneous materials are billable unless covered under the S&S labor warranty. Standard S&S coverage is one year on installation workmanship and 90 days on repairs, unless a longer period is stated in writing on the estimate or purchased as an extended labor plan. Covered workmanship corrections include labor during normal business hours. Maintenance requirements, exclusions and other written conditions apply.

Keep leak detection, leak repair, and recharge distinct

Ask what has been established so far. A low-refrigerant finding, a located leak, a repaired component, and restored operation are different points in the process. The proposal should explain which stage is included and what happens if detection identifies a component that needs a separate repair decision.

If refrigerant has been added before, keep the dates and invoices available. Repeated additions are useful history when evaluating the next step. Ask for the component or location found, the repair proposed, and how the result will be checked under the approved scope.

Make the repair fit the actual equipment

Record the equipment’s model information and refrigerant designation when they are safely available. Ask how the proposed materials and component match the system and what costs are included. Do not assume that a name mentioned in another estimate is an interchangeable substitute for your equipment’s refrigerant.

EPA describes certification requirements for work that opens or can release refrigerant from the circuit. Leave that work to qualified personnel. Your useful role is to provide the repair history, understand the scope, and retain the final documentation—not attach gauges or attempt a recharge.

• Located component and proposed correction
• Testing, refrigerant, materials, and labor included
• Parts coverage and any costs outside it
