Benefits of Generator Installation
Reliable Power During Outages
Power disruptions are common due to storms or utility maintenance. A generator provides a seamless transition when the grid fails, ensuring uninterrupted power for your appliances, lighting, and critical systems during emergencies.
Protection for Appliances and Electronics
Voltage surges during blackouts can damage sensitive electronics. A properly installed generator safeguards your HVAC system, refrigerators, computers, and other vital devices by supplying steady, clean power during sudden outages.
Enhanced Property Value
Homes equipped with backup generators are seen as more resilient and attractive to buyers. Generator installations in areas like East Honolulu can improve property value and market appeal, especially for high-end residences and multi-family dwellings.
Comfort and Safety in Emergencies
When the power goes out, maintaining comfort can be challenging—especially during hot and humid conditions. A generator allows air conditioning, lighting, and even medical devices to operate normally, protecting health and safety.
Peace of Mind for Business Owners
For business owners, downtime equals lost revenue. A commercial generator ensures operations can continue without disruption, protecting inventory, customer service, and digital infrastructure during electrical outages.
Local Code Compliance and Professionalism
Installing a generator requires compliance with specific municipal codes. Our licensed electricians understand local regulations and secure all necessary permits to ensure your installation meets legal and safety requirements.

FREQUENTLY ASKED QUESTIONS
Do I need a permit to install a generator in Honolulu?

Jerry Giles is an excellent electrician. He installed a very tricky lamp over our dining room table, replacing one that had been there for 20 years. He did a fabulous job and is reliable and easy to work with! Reasonable prices as well! We highly recommend him.
