Given my need to move the detector around, portability played a vital role in my decision-making process. I looked for lightweight models that were easy to carry. Additionally, I considered how the detector would be stored when not in use. A case or a compact design made it easier for me to keep it organized and protected.

Price Range

I noticed that AC leak detectors come in various price ranges. Setting a budget helped me narrow down my options. I found that while some models are more affordable, investing in a higher-quality detector could save money in the long run by preventing costly repairs due to undetected leaks.
