    Hi Robert,
    Motor loads, such as an air conditioning unit, do require a lot of electricity to start. In fact, air conditioners could draw up to 4 times the running amperage when they start, so when the air conditioner starts you may see some lights dim a little.

    Here are some other things that could cause your lights to dim when your air conditioner starts:
    The size of the home electrical service panel. If the electrical service is too small it may need to be upgraded.
    The size of the home, and other electrical circuit loads such as electric water heater and electric range or cook top.
    Is the home located in a rural area where the electrical utility service is weak, or experiences low voltage.
    The age and size of the air conditioner, and when was the last time it was serviced.
    Has the air conditioner been replaced with a larger unit, and if so, does the new air conditioner require a larger electrical circuit.

    I hope this helps,

    Good Day,
    I have recently bought an older home which was built in 1990. Just before the air conditioner starts, all the lights in the house dim. Actually I would never have known because the lights are never on during the day, but they dim for a very short period of time of a few seconds when the a/c unit starts.
    This I would presume is due to the load being taken by the a/c unit. Question: is this normal, and if not are there any safety issues that I need to address?

    Thank you,
