Why Your AC isn't Cooling


Your air conditioner is a closed-loop system. Unlike gas in a car, it does not "use up" refrigerant (often called Freon or Puron). If your system is low, it means there is a leak. Continuing to run an AC with low refrigerant causes the compressor to overheat and eventually fail—turning a manageable repair into a complete system replacement. When you search for ac needs freon not cooling in Iowa City, IA, you need a technician who understands the thermodynamics of cooling, not just a salesperson.

Our Leak Detection Process


Finding a pinhole leak in a copper coil is like finding a needle in a haystack. We use advanced diagnostic tools to locate the issue with precision:

  • Electronic Leak Detectors: "Sniffers" that detect minute traces of refrigerant gas in the air.
  • UV Dye Injection: We introduce a fluorescent dye into the system, which allows us to see the exact point of the leak under a UV light.
  • Nitrogen Pressure Tests: We isolate the system and pressurize it with nitrogen to hear and locate leaks in the evaporator or condenser coils.Call for priority diagnostics: (833) 963-1661

Repair and Recharge


Once the leak is found—whether it’s a vibration crack in a copper line or a rusted evaporator coil—we present you with repair options. We perform skilled brazing repairs or component replacements. After the system is sealed, we perform a precision freon refill. We weigh in the exact amount of refrigerant required by the manufacturer, checking subcooling and superheat levels to ensure maximum efficiency.





Frequently Asked Questions


Why is my AC blowing warm air?

Low refrigerant is the most common cause. When pressure drops, the indoor coil freezes up, blocking airflow, or the system simply cannot absorb heat from your home.^^

Can you just add Freon without fixing the leak?

We advise against this. "Topping and going" is a waste of your money because the refrigerant will just leak out again. It is also harmful to the environment. We prioritize fixing the leak first.^^

How often does my home AC need a recharge?

Ideally, never. Since it is a sealed system, it should retain its charge for the life of the unit. If you need a recharge, you have a mechanical failure that needs attention.^^

Do you handle R-22 (Old Freon) systems?

Yes, but R-22 is being phased out and is very expensive. We can repair these systems, but we may also provide a cost-benefit analysis on upgrading to a modern R-410A or R-454B system.^^

How much does a leak search cost?

We offer flat-rate pricing for diagnostic leak searches. We will let you know the cost upfront before we open our tool bag.
