What usually fails
- Flare, braze and mechanical joints. The most common leak points after years of vibration.
- Schrader and service valves. Small valves with seals that wear.

What affects the price
A service call is $135 for a new customer's first visit and $185 for a standard visit. Repair labor, parts, refrigerant and materials are quoted after diagnosis, and you approve the price before any work begins. The final repair price depends mainly on:
- Leak location and access
- Refrigerant type and quantity
- Whether a coil or line must be repaired
- Pressure testing time
- Scheduling
Keep it running between visits
- Do not keep adding refrigerant without finding the leak
- Report oil spots early
- Keep service records
Food-safety note. Refrigerant handling requires trained and certified technicians and appropriate recovery equipment.
Frequently asked questions
Can you just top off the refrigerant?
Topping off without finding the leak only delays the problem; we search and repair first.
How do you find a leak?
Electronic detectors, UV or bubble solutions depending on the system.
Is a leak dangerous?
Most commercial refrigerants are not toxic in small amounts but should still be handled by professionals.
How long does a leak repair take?
Depends on location and access.
Do leaks mean the system is finished?
No — many systems run for years after a leak is properly repaired.
Do you handle older refrigerants?
Call with the equipment data plate for current options.
