What You Need to Know First

The One Thing Every Homeowner Needs to Know About AC Refrigerant

Most HVAC companies will recharge your refrigerant and leave. AIRONE will not - because a recharge without a leak repair is money spent on a problem that will return within weeks or months.

Does an AC system consume refrigerant over time?

No. Refrigerant is not a consumable. It circulates in a closed loop through the compressor, condenser coil, expansion valve, and evaporator coil - and the same refrigerant charge should last the entire lifespan of the system if the loop remains sealed. If your system is low on refrigerant, the refrigerant has escaped through a leak somewhere in the circuit. Adding refrigerant without finding and repairing the leak means the new charge will escape through the same leak. AIRONE diagnoses and repairs the leak before recharging - so the repair lasts.

What causes AC refrigerant leaks in Southern California?

The most common causes of refrigerant leaks in Los Angeles area homes are vibration-induced stress fractures at the copper line set connections, corrosion of the evaporator coil - particularly in coastal South Bay and Orange County homes where salt air accelerates copper corrosion - age-related failure of the Schrader valve cores on service ports, and physical damage to the line set from rodent chewing, construction work, or improper attic access. AIRONE technicians identify the leak source using electronic leak detection and UV dye methods before recommending repair scope.

What happens if I just add refrigerant without repairing the leak?

A refrigerant recharge without a leak repair produces a temporarily cool system that will return to the same undercharged condition - typically within days to months depending on the size of the leak. You pay for the refrigerant twice. Additionally, releasing refrigerant into the atmosphere is a violation of EPA Section 608 regulations, which prohibit knowingly venting refrigerants. AIRONE technicians are EPA 608 certified and recover all refrigerant properly - no venting, no shortcuts.

Signs to Look For

Signs Your AC System May Have Low Refrigerant

These are the symptoms AIRONE technicians most commonly find in the field when a system is undercharged. None of these symptoms diagnose refrigerant as the definitive cause - only a pressure reading confirms it - but all are consistent with a low refrigerant condition.

AC Blowing Warm or Lukewarm Air

The most common symptom of low refrigerant. The system runs - compressor is on, air is moving - but the discharge air temperature at the register is much warmer than expected. The evaporator coil cannot absorb adequate heat from the air stream without sufficient refrigerant pressure.

Ice Forming on the Evaporator Coil or Line Set

Counterintuitive but common: low refrigerant causes the evaporator coil to drop below freezing, which causes moisture in the air stream to ice over on the coil surface. A frozen coil restricts airflow further and can damage the compressor. If you see ice on the copper pipe near the indoor unit, shut the system off and call for service.

AC Runs Continuously Without Reaching Setpoint

A system with low refrigerant cannot transfer enough heat to cool the space to thermostat setpoint. The system runs indefinitely - never achieving the target temperature - which accelerates wear on all running components, particularly the compressor.

Higher Energy Bills Without Explanation

An undercharged system works harder to move less heat - drawing more electricity to deliver less cooling output. If your SCE or LADWP bill is higher than usual during a period of comparable weather, refrigerant loss is one of the conditions to rule out.

Hissing or Bubbling Sound Near the Indoor Unit

Refrigerant escaping from a leak point in the refrigerant circuit can produce a hissing sound near the evaporator coil or line set connections. A bubbling sound may indicate refrigerant passing through a section of line set that has lost charge and introduced air. Either sound warrants immediate professional diagnosis.

System Short-Cycling

A low refrigerant condition can cause the system to cycle on briefly then shut off - repeatedly - as pressure safety switches detect out-of-range suction or discharge pressures and protect the compressor from damage. Short-cycling causes significant additional wear on the compressor with each start.

Refrigerant Types

R-22, R-410A, and R-454B - What Refrigerant Does Your System Use?

The refrigerant type in your system determines the service options available to you. AIRONE services all three refrigerant types but the economics and options differ significantly depending on which your system uses.

R-410A - The Current Standard for Existing Systems

Most Los Angeles homes with AC systems installed between approximately 2010 and 2024 use R-410A. The EPA’s AIM Act phase-down of R-410A in new equipment took effect January 1, 2025 - but R-410A remains available for servicing existing systems from existing stockpiles. R-410A recharge costs are rising as supply tightens following the phase-down, but the refrigerant remains serviceable. An R-410A system with a repairable leak and sufficient years of service life remaining is a reasonable repair candidate. AIRONE provides R-410A leak diagnosis, leak repair, and recharge for all compatible systems.

R-22 - Phase-Out Complete, Stockpile Only

R-22 - also known as Freon - was permanently removed from US production in 2020 under Section 605(a) of the Clean Air Act. R-22 is available only from existing stockpiles, which are finite and increasingly expensive. An R-22 system that develops a refrigerant leak faces significantly higher recharge costs than an R-410A system - and those costs will worsen each year as remaining supplies are depleted. R-22 systems cannot be converted to R-410A or R-454B. If your R-22 system has a refrigerant leak, AIRONE will provide both a leak repair and recharge quote and a full replacement quote so you can make an informed decision. For systems over 12 years old, replacement is almost always the better financial choice.

R-454B - The Standard for New Systems Installed in 2025 and Beyond

New residential AC systems installed from 2025 forward use R-454B - or a comparable low global warming potential refrigerant - following the EPA AIM Act requirement that all new residential and light commercial HVAC equipment use low-GWP refrigerants. R-454B performs comparably to R-410A in efficiency terms but carries a significantly lower environmental impact. If your system was installed in 2025 or later and requires refrigerant service, it uses R-454B. AIRONE technicians are trained and certified on R-454B system diagnosis and recharge.

Our Process

How AIRONE Diagnoses and Repairs Refrigerant Leaks

AIRONE does not add refrigerant and leave. Every refrigerant service call follows this diagnostic and repair sequence.

Step 1 - Pressure Measurement and Charge Verification

The technician connects manifold gauges to the system service ports and measures suction and discharge pressures against manufacturer specification charts for the refrigerant type and current ambient temperature. This confirms whether the system is undercharged, overcharged, or at proper charge - and rules out other conditions that can mimic refrigerant loss such as a dirty evaporator coil, restricted airflow, or a failed metering device.

Step 2 - Leak Detection

If pressures confirm an undercharged condition, AIRONE performs leak detection using electronic leak detectors calibrated for the specific refrigerant type in the system. For leaks that are not immediately locatable with electronic detection, UV fluorescent dye is injected into the system - the dye escapes with the refrigerant and fluoresces under UV light at the leak point, allowing precise identification. AIRONE identifies the leak source and location before discussing any repair options with you.

Step 3 - Written Repair Quote Before Any Work Proceeds

Once the leak source is identified, AIRONE provides a written quote for the leak repair. Common repair types include Schrader valve core replacement, line set connection re-brazing, evaporator coil leak repair or replacement, and condenser coil repair. The quote covers all parts, labor, refrigerant recovery, and recharge to proper specification. For R-22 systems, AIRONE provides both a repair quote and a replacement quote - so you can compare the cost of repairing the aging system against replacing it before committing.

Step 4 - Leak Repair

With your written approval, the technician performs the leak repair. Refrigerant is recovered from the system using EPA-compliant recovery equipment before any repair work on the refrigerant circuit begins. The repair is completed, leak-tested under pressure to confirm the seal, and the system is evacuated before recharging - a proper evacuation removes air and moisture from the circuit, both of which degrade compressor performance and lifespan if left in the system.

Step 5 - Recharge to Manufacturer Specification

After a confirmed leak repair and vacuum hold, the system is recharged with the correct refrigerant type to the manufacturer’s specified charge weight or target superheat and subcooling values - not to a generic number. Proper charge level is critical to compressor longevity and system efficiency. AIRONE documents the refrigerant type, quantity added, and post-charge pressure readings on the written service report provided at the end of the visit.

If Your System Uses R-22 - What You Need to Know Before Paying for a Recharge

R-22 refrigerant service is a special case. Before approving any R-22 recharge, every homeowner should understand the economics.

Why is R-22 refrigerant so expensive now?

R-22 was permanently phased out of US production in 2020 under Section 605(a) of the Clean Air Act. No new R-22 has been manufactured in the United States since that date. The supply available for servicing existing systems comes from stockpiles accumulated before the phase-out - stockpiles that shrink with every service call. As supply decreases against ongoing service demand, R-22 prices have risen significantly and will continue to rise. The cost of R-22 per pound for a recharge is substantially higher than R-410A and will be higher still next year than it is today.

Does it make financial sense to repair and recharge an R-22 system?

It depends on the system age and condition. For a system under 10 years old in otherwise good condition with a minor, repairable leak - yes, repair may still make sense. For a system 12 years or older with a significant leak or repeated repair history - no. Spending several hundred dollars on R-22 refrigerant for a system that will need another repair within 1 to 2 years is rarely the better financial outcome compared to proactive replacement. AIRONE provides both a repair quote and a replacement quote for every R-22 leak repair service call so you can compare both options before committing to either.

Can an R-22 system be converted to R-410A or R-454B to avoid high refrigerant costs?

No. R-22 systems cannot be converted to R-410A or R-454B. These refrigerants operate at significantly higher pressures than R-22 - pressures that R-22 system components were not designed or certified to handle. There is no refrigerant drop-in substitute that provides equivalent performance without modification. The only correct path for an R-22 system owner who wants to move off R-22 is full system replacement with equipment designed for current refrigerant standards. AIRONE provides free replacement quotes for R-22 system owners.

FAQ

AC Refrigerant Recharge Los Angeles - Frequently Asked Questions

AC refrigerant recharge cost in Los Angeles depends on the refrigerant type, the quantity required, and the leak repair scope. R-410A leak repair and recharge is less expensive than R-22 due to R-22’s limited stockpile availability following its 2020 phase-out. AIRONE charges an $89 diagnostic fee applied toward the repair cost if you proceed, and provides a written quote covering all parts, labor, and refrigerant before any work begins. Contact AIRONE at (323) 471-1037 for same-day service.
Your AC system is low on refrigerant because it has a leak. Refrigerant is not consumed - it circulates in a closed loop and the same charge should last the life of the system if the loop remains sealed. Low refrigerant always means refrigerant has escaped through a leak point somewhere in the circuit - most commonly at the evaporator coil, at line set connections, or at the Schrader valve cores on the service ports. AIRONE finds and repairs the leak before recharging.
You can, but it will not solve the problem. Refrigerant added to a leaking system will escape through the same leak - typically within days to months depending on the leak size. You will pay for the refrigerant again on the next service call. Additionally, EPA Section 608 regulations prohibit knowingly venting refrigerants. AIRONE diagnoses and repairs the leak before recharging on every refrigerant service call.
R-22 was the standard residential AC refrigerant until it was phased out of US production in 2020. R-410A replaced R-22 as the standard and is used in most systems installed between approximately 2010 and 2024. R-454B - or a comparable low global warming potential refrigerant - is now required in all new residential AC equipment installed from 2025 forward under EPA AIM Act regulations. R-22 systems cannot be converted to R-410A or R-454B. AIRONE services all three refrigerant types.
If the leak is properly found and repaired before recharging, the recharge should last the remaining service life of the system - refrigerant does not deplete in a sealed circuit. If the leak is not repaired, the recharge will last only until the refrigerant escapes again through the same leak. This is why AIRONE does not perform recharges without leak diagnosis and repair.
No. Running an undercharged system causes the compressor to operate under abnormal suction pressure conditions - pulling harder to circulate insufficient refrigerant through the circuit. This accelerates compressor wear and can lead to compressor failure, which is the most expensive single repair in a residential AC system. If you suspect low refrigerant, shut the system off and schedule a diagnostic. Do not continue running the system.
Yes. AIRONE services R-22 systems for refrigerant leak diagnosis, leak repair, and recharge. For R-22 systems with significant leaks or systems over 12 years old, AIRONE provides both a repair quote and a full replacement quote so you can compare both options before committing. R-22 recharge costs are significantly higher than R-410A due to the 2020 phase-out and limited remaining stockpile, and costs will continue to rise each year.
EPA Section 608 of the Clean Air Act requires all technicians who purchase or handle refrigerants to hold a valid EPA 608 certification. The certification covers safe refrigerant handling, recovery procedures, and environmental regulations - including the prohibition on knowingly venting refrigerants into the atmosphere. All AIRONE technicians who perform refrigerant service hold current EPA 608 certification. This is required by federal law and is part of AIRONE’s licensing as a C-20 contractor.
