Will a 115V Dual Inverter window AC trip my home's circuit breaker?

Traditional non-inverter units draw massive startup current spikes (often 30 to 40 amps for a split second) when the compressor kicks on, tripping older breakers. LG Dual Inverter & GE Built-Ins feature soft-start electronics that gradually ramp up power, virtually eliminating breaker trips.

Can I use an extension cord with a 115V window air conditioner?

We strongly recommend plugging directly into a wall receptacle. If necessary, only use a heavy-duty, 14-gauge or 12-gauge appliance-rated extension cord rated for 15 amps to prevent overheating and voltage drop.

SOFT-START INVERTER TECHNOLOGY

Stop Tripping Older Plantation Home Breakers

Many historic homes in Kaimuki, Kalihi, Pearl City, and Kailua have older 15-amp wiring. When a conventional AC compressor clicks on, it creates a massive electrical surge that trips the breaker. Our LG Dual Inverter compressors ramp up smoothly from zero, eliminating inrush current spikes.

Clean Jobsite Standard: Our technicians lay protective floor drop cloths under every unit during work, leaving your home cleaner than when we arrived.
