Why identify the unit so precisely?

Because a restaurant has several pieces of refrigeration and a manager who calls every one of them 'the cooler.' Make, model, serial, and location turn your invoices into a service history — which is what makes you the tech they call rather than whoever answers first.

How should refrigerant be recorded?

Type and pounds, added and recovered, on every invoice. It's a genuine cost that moves with market prices, it's a record you want for your own compliance, and it makes the charge legible to the customer.

Should the after-hours rate be a separate line?

Yes — a call-out fee plus a premium labor rate, both quoted on the phone before you drove. Visible and pre-agreed, it's a service. Folded silently into a higher hourly total, it reads as opportunism at exactly the moment the customer felt most vulnerable.

Commercial pricing: Compressors vs. TXV valves vs. emergency call-outs

Commercial refrigeration technicians must price high-overhead emergency calls accurately to protect restaurant food inventory:

Emergency After-Hours Labor Rates ($145–$225 per hour): Restaurant walk-in cooler failures at 9 PM threaten thousands of dollars in perishable food. Charging a dedicated call-out fee ($150–$250) and emergency hourly labor reflects 24/7 readiness.
Compressor Replacement ($1,400–$3,800 total installed): Involves pump-down, recovering old gas, brazing in new Copeland or Tecumseh compressor, replacing liquid line filter driers, pulling a deep vacuum (<500 microns), and charging refrigerant.
Thermostatic Expansion Valves & Defrost Controls ($350–$650 installed): Replacing failed TXV valves, defrost termination thermostats, or digital temperature controllers.

EPA Section 608 compliance and leak search requirements

Federal regulations require strict tracking of synthetic refrigerants:

EPA Refrigerant Log (Pounds & Type): Always itemize exact pounds of R-404A, R-448A, R-407C, or R-134a added to a system. For systems holding >50 lbs, calculate and print the annual leak rate percentage to comply with EPA Section 608 laws.
Compressor Amp Draw & Superheat/Subcooling: Record compressor running load amps (RLA), suction pressure, head pressure, superheat, and subcooling on the invoice to verify optimal performance.

Corporate Net 30 billing and preventative maintenance cross-sells

Corporate WO/PO Matching: Commercial restaurant chains require matching internal Work Order numbers on the invoice before approving payment.
Preventative Maintenance Contracts ($120–$250/visit): Pitch quarterly condenser coil cleaning, door gasket inspection, and drain line flushing to prevent catastrophic summer breakdowns.
