AC Turning On and Off Repeatedly? Here’s What You Need to Know
Comfort should improve gradually after your thermostat requests cooling. When the air conditioner delivers only a few minutes of cold air before falling silent—and repeats the same behavior shortly afterward—the system is not completing its normal operating cycle. HVAC professionals refer to this pattern as short cycling. Instead of staying on long enough to cool the entire property, the equipment repeatedly starts and stops at unusually short intervals. A normal residential cooling cycle commonly lasts around fifteen to twenty minutes. This gives the AC enough time to pull heat from the indoor air, distribute cooling through the ductwork, and reduce excess humidity. Brief cycles do not allow the system to complete those tasks. The room near the thermostat may become comfortable first, while bedrooms and other distant areas remain warmer. The air may also feel damp or sticky because the equipment has not operated long enough to remove sufficient moisture. Frequent cycling can also incr...
