Few problems are more frustrating than an air conditioner that won’t stay on long enough to cool your home. There are a number of underlying issues that can cause your AC unit to short cycle, and it’s important for homeowners to understand what the possible problem could be so they can prepare accordingly.
Our team has years of experience resolving all sorts of air conditioning malfunctions, including AC units that refuse to remain operational. Allow us to help you understand what the problem might be by reading the blog below!
What is System Short Cycling?
When an air conditioner functions properly, it should run between 10 and 15 minutes to cool down the home quickly and efficiently, then shut off before repeating the cycle. If your AC only stays operational for a few minutes before shutting down, this is known as system short cycling. Short cycling is a fairly common issue that HVAC technicians run into, and the problem has a number of different possible causes.
Allowing your unit to continue short cycling without scheduling necessary repairs can cause your air conditioner to experience poor efficiency, performance, and reduced lifespan. For this reason, it’s imperative that homeowners identify the issue early and make the appropriate AC repair service arrangements.
What Causes Air Conditioners to Short Cycle?
Many underlying issues can cause your air conditioner to short cycle. The following are just some of the possible causes that can leave you with an underperforming AC:
- Faulty Thermostat: If your thermostat becomes damaged, it can cause your air conditioner to short cycle. Even thermostats that are placed in a poor location can cause your AC to shut off prematurely — especially if the thermostat is located near a duct return, is in a sunny location, or is too close to a hot appliance.
- Electrical Issues: There could be an electrical problem with your control boards, sensors, relays, fuses, or start capacitors. Sometimes a simple power reset can help restore the system to working condition.
- Filthy Filters: Whether your air filter is clogged or there is debris in your ductwork, these can easily lead to system short cycling when left untreated.
- Dirty Coils: Dirty or frozen evaporator or condenser coils can prevent the proper transfer of heat, causing the system to overheat and shut down before it should. In the event of freezing, the system may shut down until it has had time to thaw.
- Refrigerant Levels: If there isn’t enough refrigerant in your system due to a leak or low charge, it can cause the safety switch to trip within your air conditioner, shutting it down before it’s had time to cool your home.
- Unit Size: An oversized air conditioner can cause frequent system short cycling, leading to poorer indoor air quality and home comfort as a result.
While some short cycling issues can be easily resolved by simply resetting the power in your home, changing your thermostat batteries, or switching out your air filters, others require the keen eye of a knowledgeable HVAC technician to repair.
