If your AC compressor shuts off just a few minutes after starting, it’s a problem you shouldn’t ignore. For business owners in Lamar, Missouri, a reliable air conditioning system is essential for maintaining a comfortable, productive environment. When the compressor fails to stay on, the root cause often lies in one of several mechanical or electrical issues.
Here’s a breakdown of what might be going wrong and what you can do about it.
What the AC Compressor Does
The compressor is the heart of your air conditioner. It pressurizes the refrigerant and helps circulate it through the system to absorb and remove heat. If the compressor turns off after 2–3 minutes, your system can’t cool your space properly. And if you’re running a storefront, office, or restaurant, this can lead to uncomfortable conditions and lost customers.
Common Causes of Short Cycling
Short cycling — when the compressor turns on and off too quickly — can happen for several reasons:
-
Low Refrigerant Levels: Leaks in the refrigerant line reduce pressure in the system. This can trigger the compressor to shut off prematurely as a safety measure.
-
Faulty Thermostat: If the thermostat misreads room temperature or malfunctions, it can signal the system to shut off too early.
-
Dirty Air Filter or Coils: Restricted airflow due to clogged filters or dirty coils causes the system to overheat, which may lead to the compressor shutting down.
-
Electrical Issues: Loose wires, a faulty capacitor, or a malfunctioning control board can cause irregular compressor behavior.
-
Oversized AC Unit: If your unit is too large for the space, it may cool the area too quickly, causing the compressor to turn off before completing a full cycle.
How To Know If Your AC Compressor Is Bad
Signs that your compressor might be failing include:
-
Clicking, rattling, or buzzing noises
-
Warm air coming from vents
-
Circuit breaker tripping frequently
-
Higher-than-usual energy bills
-
Compressor shuts off after 2–3 minutes
If you notice any of these, it’s time to call a professional HVAC technician for a full inspection.
How Long Does an AC Compressor Last?
On average, a commercial AC compressor lasts 10 to 15 years, depending on usage, maintenance, and environmental conditions. In Lamar’s humid summers, systems often work harder, so annual inspections and regular filter changes are key to maximizing compressor lifespan.
