 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.

 Trustindex verifies that the original source of the review is Google. What a great company this is. I called at 3:00 on a Friday afternoon and they had a tech in my area who was there at 6. 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 Electrical Hazards Before They Happen

Disconnects and whips are exposed to the weather and can degrade over time. The Lighthouse Annual Maintenance Plan includes electrical safety checks at every visit, catching corrosion, damage, and code issues before they become a hazard — season after season.

Still Have Questions? Let Us Help

What is an AC disconnect and whip?

The disconnect is the electrical box mounted near your outdoor unit that safely cuts power for service, and the whip is the flexible conduit that carries power from the disconnect to the unit. Together they're a required safety component — allowing power to be shut off safely and protecting the wiring connection.

Why does my disconnect or whip need to be replaced?

Because they're outdoors, disconnects and whips are exposed to weather, corrosion, and wear. A corroded box, damaged whip, or loose connection can cause power problems, safety hazards, or a failed inspection. Replacing them keeps your system safe and code-compliant.

Are these components a safety hazard if they fail?

They can be. Damaged or improperly installed disconnects and whips can lead to electrical shorts, scorching, or shock risk. Because they carry the power to your unit, keeping them in good condition and up to code is important for the safety of your home and anyone servicing the system.

Do disconnects and whips need to meet code?

Yes. Electrical code requires a proper disconnect and whip for HVAC equipment, and requirements can change over time. If yours were installed long ago or by a previous owner, they may no longer meet current code. We install and replace them to current standards so your system passes inspection.
