Common AC Problem: Unit Shuts Off Repeatedly

August 29, 2018

During the summer, your air conditioner (AC) works harder and longer.  That high demand may cause a problem to rear its ugly head.  In this multi-part post, we’ll take a look at some of the most common AC problems, talk about the possible causes, and provide suggestions for tackling each problem.

Unit Shuts Off Repeatedly

If the unit is turning on and off repeatedly, or has difficulty switching on, or you hear a choking and stuttering sound while turning it on, there is short cycling problem.  This can severely damage the compressor, stress the other components, and will consume excess electricity.  Some possible causes are an electrical short somewhere in the system, poor wiring (this is serious and could cause a fire), a damaged or failed part in the system, dirty air filters, or blocked ducts preventing the flow of air.  If you continue to have a short cycling problem after checking your air filter and vents, turn the system off and contact an AC professional.  In some cases – especially if the problem has persisted a while – you may require a new AC unit entirely..

Avoid AC Problems

Summer can be the best time of the year, so don’t let air conditioning problems hinder you from enjoying it.  Be sure to get annual AC maintenance visits, so it will run efficiently and be ready for the high demand of the summer’s heat.  If you live in the Nashville area and experience any heating or cooling problems, call on Interstate AC Service at (615) 832-8500.
