Why does my AC keep running low on refrigerant?

Air conditioners are sealed systems — they don't use up refrigerant over time. If yours is low, it almost always means there's a leak somewhere. That's why simply adding more refrigerant is only a temporary fix. Finding and repairing the leak is the only lasting solution.

How do I know if my AC has a refrigerant leak?

Common signs include warm air from the vents, weak cooling, ice on the refrigerant lines or coil, hissing or bubbling sounds, and a system that runs constantly but never cools. If you notice these, a professional leak detection can pinpoint the cause.

Is it worth repairing a refrigerant leak or should I replace the AC?

It depends on the age of your system and the location of the leak. For newer systems, repairing the leak is usually well worth it. For older systems with major leaks, we'll give you an honest comparison so you can decide what makes the most financial sense.

Is a refrigerant leak dangerous?

Refrigerant leaks reduce your system's efficiency and can damage the compressor if left unaddressed — an expensive repair. While small leaks aren't an immediate safety emergency, they should be repaired promptly to protect your equipment and keep your home cooling properly.

How much does refrigerant leak detection and recharging cost?

Cost depends on the leak's location and how much refrigerant your system needs. We provide upfront pricing after diagnosing the leak — so you know exactly what the repair and recharge will cost before we begin, with no surprise charges.
