Why Do the Lights Dim When the AC Starts?

A properly functioning air conditioner does not run nonstop. It starts up when temperatures get too high. Then, if it’s working properly and you have not set the thermostat unreasonable low, it turns off once it reaches an ideal range.

However, even if this seems to be going smoothly, there is something that might concern you about your air conditioner’s startup. Do the lights dim every time your air conditioner turns on? We’d like to address that in today’s guide, and encourage you to call an expert to solve the issue.

Faulty Connections

It could be that the wiring connecting your air conditioning system is corroding or otherwise damaged. A technician can check the electrical connections to see if any need tightening or replacement. For major electrical wiring issues that stem from your home, you’ll need to call in an electrician.

Capacitor Issues

The motors in air conditioning systems use up a whole lot of energy each time they start up. The air conditioner uses so much electricity to start, in fact, that it cannot simply draw from your power supply, or else it would trip the breakers.

Start capacitors store up energy for the air conditioner to use every time it starts up. That way, it’s not using an exorbitant amount of energy from your electrical supply all at once. It acts sort of like a battery—and it wears down like a battery too. You’ll probably need to replace these every few years, and that might resolve the dimming light issue.

Problems with the Electrical Panel

Unfortunately, your circuit breaker may simply not have the capacity to power such a heavy load. If this is the case, your HVAC technician will likely recommend that you call in an electrician to upgrade your panel.
