What MCC 7623 covers
Merchant Category Code 7623 is the ISO 18245 identifier used by the card networks for air-conditioning & refrigeration repair shops. Acquirers, issuers and regulators use this code to set interchange, scheme fees, fraud rules and reporting categories for every transaction your business processes.
HVAC and refrigeration repair services. Choosing the right MCC is critical: an incorrect code can lead to higher interchange, surcharges, or, in regulated categories, declined transactions and account holds.
MCC 7623 encompasses air-conditioning and refrigeration repair shops. These merchants typically perform onsite repairs or installations in residential or commercial settings.
Ticket sizes can vary significantly, from minor repairs to substantial system replacements. Transaction frequency is generally low per customer, often driven by equipment malfunction or scheduled maintenance.
Chargebacks, whilst not high, can stem from dissatisfaction with repair quality ('Services Not as Described'), claims of work not being completed as agreed, or disputes over unexpected pricing.
Given that a service is rendered, fraud risk is typically low as transactions often occur face-to-face or via phone after a service call.
There are no specific scheme programmes for this MCC. Cardflo's comprehensive APM coverage, including Open Banking payments, can cater to preferences for larger ticket items, potentially offering a secure, lower-cost alternative to card payments.
Merchants in air-conditioning and refrigeration repair should primarily use mobile POS solutions for on-site payments, ensuring card-present processing. For larger, project-based work, consider taking partial payments or deposits upfront, leveraging secure CNP methods with 3DS2, to manage cash flow and mitigate risk.
Given the emergency nature of some repairs, flexible payment options like 'pay by link' are valuable, but always reinforce proof of service. Explicitly detail all services rendered, parts used, and associated costs on invoices.
Maintain clear records of service appointments, customer agreements, and photo documentation of work before and after completion to aid in dispute resolution.
Acquirer and acquirer assessment stance.
Low-risk standard board. This MCC presents a stable risk profile.
Standard underwriting and monitoring are appropriate, usually without the need for additional reserves.
Dispute and chargeback profile.
The most common chargeback reason codes for HVAC services are 13.1 / 4853 (services not as described) and 13.3 / 4855 (merchandise/service not received).
These typically arise when a repair is perceived as ineffective, or the work agreed upon is not completed to the customer's satisfaction. To defend, provide comprehensive service reports detailing work performed, parts installed, and diagnostic findings.
Obtain customer signatures confirming job completion and satisfaction on-site. Photo evidence of the completed work, coupled with dated service logs and technician notes, is critical for successful dispute defence.

Common questions
How can HVAC repair services effectively manage customer expectations to reduce disputes?
Effective expectation management involves providing detailed, itemised quotes before work begins, explaining the scope of work clearly, and documenting any changes approved by the customer.
Post-service, a thorough review with the customer and obtaining a signature acknowledging completion and satisfaction can significantly reduce 'Services Not as Described' disputes.
What payment methods are most suitable for onsite HVAC repair work?
For onsite HVAC repair work, mobile POS terminals that support EMV chip and PIN are ideal for secure card payments. Additionally, offering mobile wallet options like Apple Pay and Google Pay provides convenience.
For larger commercial jobs, solutions like payment links or direct bank transfers facilitated by Open Banking can be efficient and secure.
Are there any specific invoicing best practices for MCC 7623 to prevent chargebacks?
Best practices include issuing clear, itemised invoices that detail parts, labour, and any service fees. Ensure the invoice matches any upfront quotes and includes the merchant's contact information.
For recurring maintenance plans, clearly outline billing cycles and cancellation terms. Retain signed copies of work orders and completion certificates to support transactions against disputes.
How can HVAC repair businesses best handle advance payments or deposits for large installations or emergency repairs?
When taking advance payments or deposits for large HVAC installations or emergency repairs, always process these transactions using secure Card-Not-Present methods incorporating 3DS2.
Clearly itemise what the deposit covers, such as parts procurement or a portion of labour, and outline the cancellation policy in your terms of service. Provide customers with a detailed invoice or work order upfront.
Maintaining transparent communication about the payment schedule and expected work completion can significantly reduce customer disputes related to payment timing or the scope of service, thereby safeguarding against chargebacks.
What operational steps should air-conditioning repair shops take to prevent 'Services Not as Described' chargebacks?
To prevent 'Services Not as Described' chargebacks, ensure that your technicians thoroughly explain the diagnosed issue, the proposed solution, and the expected outcome to the customer before beginning any work. Provide written quotes detailing all parts and labour.
After completion, conduct a post-service check with the customer, demonstrating the repair's effectiveness. Obtain a signature confirming their satisfaction with the service.
Document all work with time-stamped photos, particularly before and after shots, of the repaired equipment. These practices create a robust evidence trail, crucial for defending against any claims of inadequate service.
