Warning Signs You May Have a Refrigerant Leak

Catching a refrigerant leak early prevents bigger, more expensive damage to your AC system. These are the most common signs something is wrong:

  • Warm or lukewarm air coming from your vents even when the thermostat is set low
  • Ice buildup on the refrigerant lines or evaporator coil
  • Your system runs constantly but never reaches the set temperature
  • Higher-than-normal energy bills without a clear reason
  • A hissing or bubbling sound near the indoor or outdoor unit

If you notice any of these symptoms, do not keep running your system. Continuing to operate an AC with low refrigerant can damage the compressor, which is one of the most expensive components to replace.

How Schiller Diagnoses and Repairs Refrigerant Leaks

Our technicians use electronic leak detection equipment to locate refrigerant leaks quickly and accurately. We do not guess and we do not simply add refrigerant without addressing the source. Simply topping off the refrigerant without fixing the leak is a temporary patch that wastes your money and damages your system over time.

Once the leak is located, we repair it properly and then recharge your system to the manufacturer-specified refrigerant level. We work on all major AC brands and handle both R-22 and R-410A refrigerant systems. Our flat-rate pricing means you know exactly what the repair will cost before any work begins, with no surprises on the final invoice.

Frequently Asked Questions About Refrigerant Leak Repair

  • How much does refrigerant leak repair cost in Tempe, AZ?

    Costs vary depending on the leak location and the amount of refrigerant needed to recharge the system. Schiller Heating & Cooling, Inc. uses flat-rate pricing, so you will receive a clear, upfront quote before any work is done.

  • Can I just add more refrigerant without fixing the leak?

    Adding refrigerant without repairing the leak is a short-term fix that will cost you more in the long run. The refrigerant will continue escaping, and running the system low can eventually burn out the compressor.

  • Is a refrigerant leak dangerous to my family?

    Modern refrigerants are generally low-risk in a residential setting, but a leaking system should still be addressed promptly. Exposure to refrigerant in an enclosed space can cause dizziness or irritation, and the bigger risk is the damage it does to your AC unit.

  • How long does a refrigerant leak repair take?

    Most repairs are completed in a single visit, typically within one to three hours depending on the leak location. Our NATE-certified technicians come equipped to handle most repairs on the spot.
