Our Solution

RUNASO provides AC recharge by first determining whether the RV air conditioning system is designed to be recharged. If eligible, refrigerant levels are measured, leaks are checked where accessible, and the system is recharged to specification. This service restores refrigerant balance but does not convert sealed systems or bypass manufacturer design limits.

System Type Verification

Serviceable vs sealed systems are identified.

Leak Awareness

Recharge is not performed on leaking systems.

Post-Recharge Testing

Cooling response and pressures are checked.

What's Included

AC System Assessment

Determination of recharge eligibility.

Refrigerant Recharge (if applicable)

Charging to manufacturer specifications.

Operational Check

Cooling output and system behavior verified.

How The Service Works

Pricing

AC recharge pricing depends on system type, refrigerant type, and access. Quotes are provided only after confirming system eligibility.

Serviceable vs sealed system

Refrigerant type

Leak condition

No unnecessary recharges on failing systems.

Safety & Compliance

Refrigerant handling follows regulations.

Frequently Asked Questions

What does AC recharge mean for an RV air conditioning system?

AC recharge involves restoring the correct refrigerant level in the RV air conditioning system after leaks or loss of charge, allowing the system to cool efficiently again.

How do I know if my RV AC needs a recharge?

Common signs include weak cooling, warm air blowing from vents, longer run times, and the AC struggling to maintain temperature even in moderate weather.

Is low refrigerant the only reason an RV AC stops cooling?

No. Poor airflow, dirty coils, electrical issues, or compressor problems can also reduce cooling. Proper diagnostics are required before recharging.

Does an RV AC system normally lose refrigerant over time?

No. Refrigerant is a sealed system. If refrigerant is low, it usually indicates a leak that must be identified and addressed before recharging.

Can you recharge an RV rooftop AC without fixing a leak?

Recharging without repairing leaks may result in temporary improvement, but cooling performance will decline again. Leak detection is an important part of the service.

Is AC recharge different for rooftop RV units compared to home systems?

Yes. RV rooftop AC units are compact, vibration-prone, and exposed to weather, which makes proper handling and system evaluation especially important.

Can electrical problems affect AC cooling even with proper refrigerant levels?

Yes. Faulty capacitors, low voltage, or control board issues can prevent the compressor from operating correctly, mimicking low refrigerant symptoms.

How long does an RV AC recharge usually take?

Most AC recharge services are completed within a few hours, depending on diagnostics, leak detection, and system condition.

Is it safe to continue using the RV AC if refrigerant is low?

Running the AC with low refrigerant can strain the compressor and lead to more serious damage, increasing repair costs over time.

Can AC recharge improve cooling in extreme heat?

If low refrigerant is the cause, proper recharge can restore cooling efficiency. However, overall performance also depends on insulation, airflow, and system capacity.

Is AC recharge better than replacing the entire AC unit?

When the system is otherwise healthy, recharge and minor repairs are far more cost-effective than full unit replacement.

When should RV AC refrigerant levels be checked?

Refrigerant levels should be checked when cooling performance drops, before peak summer travel, or during routine HVAC inspections.

Schedule an AC Performance Inspection

AC recharge applies only to RV air conditioning systems that are serviceable and approved for refrigerant charging. This service focuses on diagnosing refrigerant-related performance loss and restoring proper charge levels—without guaranteeing improved cooling if leaks, compressor issues, or non-serviceable systems are involved.
