Lights Flickering When AC Comes On - Causes and Solutions

If you have experienced lights flickering when your AC turns on, you may be wondering what is causing this issue and how to resolve it. Don't worry, you've come to the right place! In this article, we will explain the common reasons behind lights flickering when the AC comes on and provide effective solutions to help you overcome this problem.

Understanding the Problem

Lights flickering when your AC system starts can be an unsettling experience. It not only affects the comfort of your home or office but may also raise concerns about potential electrical problems. However, in most cases, this issue is not a major cause for alarm. Often, it is caused by a temporary surge in electrical demand when the AC's compressor kicks in.

Common Causes of Lights Flickering

1. Inadequate Wiring: If your electrical system isn't properly designed or wired, it may struggle to handle the sudden increase in power demand from the AC unit. This can lead to lights flickering.

2. Voltage Fluctuations: When the AC compressor turns on, it requires a significant amount of electricity. If the voltage supplied by the utility company is inconsistent, it can cause the lights to flicker.

3. Loose Connections: Loose electrical connections anywhere in your electrical system can lead to voltage drops, resulting in flickering lights. It's important to investigate and fix any loose connections.

4. Undersized Breaker: If your AC system is connected to an undersized breaker, it may trip or cause lights to flicker when the compressor starts. This is a safety feature designed to prevent electrical fires.

Solutions to Resolve the Issue

To resolve the problem of lights flickering when the AC comes on, consider implementing the following solutions:

1. Electrical Inspection and Upgrade

Hire a qualified electrical contractor, like Proflo HVAC, to perform a thorough inspection of your electrical system. They will identify any shortcomings in the wiring or connections and recommend appropriate upgrades to ensure the system can handle the AC's power demand efficiently.

2. Voltage Stabilizer Installation

If voltage fluctuations are a concern in your area, installing a voltage stabilizer can help regulate the electricity supply. This device ensures a consistent voltage level, preventing lights from flickering when the AC cycles on and off.

3. Breaker Panel Upgrade

An undersized breaker can cause lights to flicker or trip when the AC turns on. Consulting an electrician to upgrade the breaker panel to a size suitable for your AC unit can prevent this issue and improve safety.

4. Electrical Connection Checks

Inspect all electrical connections, including outlets, switches, and junction boxes. Secure any loose connections and ensure they are properly tightened. Doing so can eliminate voltage drops that contribute to lights flickering.
