Why Is My Air Conditioner Running Constantly?

If you’ve noticed that your air conditioner seems to be running non-stop, even on mild days, it can be concerning and costly. Several factors could be causing this issue, which could require simple adjustments to correct or require professional attention.

Understanding the reasons behind your AC’s constant operation can help you troubleshoot effectively and decide when it’s time to call in the West Chester, OH, HVAC system experts at Robinson Heating and Air Conditioning, Inc. for air conditioning repair.

 

How Long Should Cooling Systems Run?

Heating and cooling systems shouldn’t run non-stop. A typical cooling cycle for air conditioners and heat pumps usually lasts around 15 to 20 minutes under normal circumstances. This duration allows the AC to efficiently lower the temperature inside your home to the set thermostat level before cycling off. During this time, the system’s compressor and fan work together to extract heat from the indoor air and expel it outside.

If your air conditioner’s cooling cycles are significantly shorter or longer than this range, it indicates an issue with your air conditioning system that requires AC repair from a professional HVAC technician.

 

Reasons Why Your Air Conditioning Unit Is Constantly Running

Using the Wrong Thermostat Settings

One of the most common reasons for an air conditioner to run continuously is incorrect thermostat settings. It’s not uncommon for West Chester customers to set their thermostats to a very low temperature in hopes of cooling the home faster—this doesn’t do anything but overwork their cooling systems.

If your thermostat is set too low compared to the actual temperature inside your home, your AC system or heat pump will keep running to reach that lower temperature, regardless of how long it takes. Make sure your thermostat is set to a comfortable temperature that matches your cooling needs without overworking your system.

Air Filter Is Dirty

Clogged or dirty air filters can restrict airflow, making it harder for your air conditioner to cool your home efficiently. When airflow is restricted, your AC may run longer to achieve the desired temperature, leading to constant operation.

Check your air filters regularly and replace them as recommended by the manufacturer to ensure optimal airflow and energy efficiency. During the summer, it’s a good idea to check the air filter monthly, as it may clog faster due to heavy HVAC system use.

AC Refrigerant Is Low

Refrigerant is vital for your air conditioner’s cooling process. If your system is low on refrigerant due to a leak or improper initial charging, it can lead to inadequate cooling and continuous operation as the system tries to compensate. Signs of low refrigerant include reduced cooling performance, ice buildup on the refrigerant line, or higher-than-normal energy bills.

If you suspect a refrigerant issue, it’s essential to have a qualified HVAC technician inspect and recharge your system as needed. This is an issue we can identify during annual maintenance services, so it can be taken care of ahead of the cooling season.

Dirt Buildup on Evaporator Coils

Dirty evaporator coils can significantly impair the efficiency of your air conditioner, causing it to run longer than necessary to achieve the desired cooling. As dirt and debris accumulate on the coils, they create a barrier. This forces the AC system to work harder and longer to cool your home because it cannot effectively absorb heat from the indoor air.

Over time, this inefficiency not only increases energy consumption but also puts strain on the compressor and other components, potentially leading to premature wear and higher maintenance costs. Regular maintenance, including cleaning or professional servicing of evaporator coils, is essential to ensure optimal cooling performance and extend the lifespan of your air conditioning system.

Condenser Coils Are Clogged

Over time, condenser coils can accumulate dirt, dust, and debris, which hinders the system’s ability to release heat outdoors and reduces your air conditioning efficiency. When the condenser coils are dirty, your air conditioner may run longer to cool your home effectively.

Regular maintenance, including cleaning the condenser coils, can improve your system’s efficiency and prevent unnecessary wear and tear. Our certified technicians can take care of your coils when we perform spring maintenance services.

Air Conditioning Unit Isn’t the Right Size

If your air conditioner is too small for the space it’s intended to cool, it may struggle to maintain a comfortable temperature, causing it to run constantly. Conversely, an oversized AC can short cycle, turning on and off frequently, which also wastes energy and reduces efficiency.

Ensuring your AC unit is properly sized for your home’s cooling needs is crucial for optimal performance and energy savings. If your unit isn’t sized correctly, the only solution to put an end to this issue is installing a new air conditioning system.

Ductwork Is Leaking

Leaky or poorly insulated ductwork can lead to cooled air escaping before it reaches your living spaces. Plus, warm air from unconditioned areas of the home can enter the ducts and increase the temperature of the air traveling through. As a result, your air conditioner may run longer to compensate for the lost cooling, leading to constant operation.

Having your ductwork inspected and sealed by a professional can improve airflow efficiency and reduce energy consumption. With properly sealed ductwork, your rooms can receive the intended amount of cooling so your cooling system can run shorter cycles.

 

When to Call Our Cooling Experts

While some issues can be addressed with simple maintenance tasks, such as changing air filters or cleaning coils, others require professional diagnosis and air conditioning repair. If you’ve checked thermostat settings, replaced filters, and ensured no obvious obstructions, but your air conditioner continues to run constantly, it’s time to contact our West Chester heating and cooling technicians.
