Lights Flicker When AC Comes On: Understanding the Issue and Solutions

Introduction

Greetings! Welcome to Proflo HVAC, the go-to contractors for all your heating, ventilation, and air conditioning needs. Today, we're here to discuss a common issue many homeowners face - lights flickering when the AC comes on. We understand the frustration this can cause, and that's why we've prepared this detailed guide to help you understand the reasons behind this problem and provide you with effective solutions.

Why Do Lights Flicker When the AC Comes On?

When you notice your lights flickering every time you turn on your air conditioning unit, it can be quite concerning. However, it's important to know that this issue is relatively common and can be attributed to a few underlying causes. Let's explore some of the most common reasons:

1. Electrical Load

One of the main reasons lights may flicker when the AC kicks in is an electrical load imbalance. The sudden surge of power required by the AC unit can draw significant electrical current, causing a momentary drop in voltage. This voltage drop can result in flickering lights, especially if the electrical circuits in your home are not properly sized or if the AC unit is on the same circuit as the lights.

2. Loose Electrical Connections

Another culprit behind flickering lights is loose electrical connections. Over time, electrical connections can become loose due to various reasons, including normal wear and tear. When the AC unit starts, its motor draws a significant amount of current, leading to voltage fluctuations. These fluctuations can further exacerbate the effects of loose connections, resulting in lights flickering.

3. Voltage Fluctuations from the Power Grid

Power grid fluctuations are beyond the control of individual homeowners. However, they can still cause lights to flicker when the AC comes on. Voltage irregularities from the power grid can impact the stability of your home's electrical supply, leading to flickering lights. In such cases, contacting your utility provider is advisable to address the issue.

What Can You Do to Fix the Problem?

Now that we have identified some common reasons behind lights flickering when the AC comes on, let's explore potential solutions to this issue:

1. Upgrading Electrical Circuits

If you frequently experience lights flickering, it might be a sign that your electrical circuits are inadequate for the electrical demands of your home. Consulting a certified electrician to assess your electrical system and potentially upgrade your circuits can help mitigate the problem. Properly sized circuits will handle the electrical load more efficiently, reducing the chances of lights flickering.

2. Checking and Tightening Electrical Connections

To eliminate the possibility of loose electrical connections causing flickering lights, it is important to have a professional electrician inspect and tighten all connections in your electrical system. This thorough examination will ensure a solid and uninterrupted flow of electricity, preventing any voltage fluctuations that may lead to lights flickering.

3. Installing Voltage Stabilizers or Surge Protectors

If voltage fluctuations from the power grid are a recurring issue in your area, installing voltage stabilizers or surge protectors can significantly reduce the impact on your electrical system. These devices help regulate the voltage, ensuring a more stable power supply to your home. Discussing this option with a qualified electrician can provide you with more tailored advice.
