Flickering lights may indicate a loose connection, voltage fluctuation, or an overloaded circuit. It’s best to have a licensed electrician inspect the issue to ensure safety.

Breakers trip to protect your system from overloads or short circuits. Repeated tripping could mean too much load on the circuit, a faulty breaker, or damaged wiring.
-
We offer flat-rate pricing and upfront quotes. The cost depends on the nature of the issue, but simple diagnostic visits are typically affordable and can prevent much more costly damage down the road.

Basic checks like resetting a breaker are fine, but anything involving wiring, buzzing outlets, or burnt smells should always be handled by a licensed electrician for safety.
