Q: My lights flicker, dim or don’t come on, is this a problem with my A/C and Heating system?
A light flicker or dimming of lights happens when there is a dip in the voltage. In many cases, this voltage sag is caused by any home appliances that require large amounts of power to start up. The light flicker may only last a fraction of a second and usually isn’t anything to be concerned about, but if it happens all the time or is concerning, you should have an electrician out to make sure all wiring is secure and tight and that all equipment is properly grounded. If your electrician gives you a pass then contact your utility company to check the wire and transformer servicing the house to ensure that there are no issues on the power company side.
