 Trustindex verifies that the original source of the review is Google. The tech who came out to clear drip line from ac unit was great and very efficient. Would use their service again if needed.  3 text messages for this survey in a week seems a little heavy. Doing this to stop the text messages.

He quickly diagnosed the problem and got us up and running again. Very friendly and professional all around. I highly recommend and will definitely use them in the future.

Catch Leaks Before They Cost You

Small refrigerant leaks often go unnoticed until your system fails on the hottest day. The Lighthouse Annual Maintenance Plan checks your refrigerant levels and lines at every visit, catching leaks early before they leave you without cooling — season after season.

Still Have Questions? Let Us Help

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.
