What Causes an AC Fan to Run Without the Compressor?

Image
A spinning outdoor fan can be misleading. It may suggest that your air conditioner is operating normally, especially when the indoor blower is also pushing air through the vents. However, if the rooms stay warm and the air does not feel properly cooled, the compressor may not be running. The fan and compressor work together, but they are responsible for different stages of the cooling process. The condenser fan draws air across the outdoor coil so the system can release heat. The compressor moves refrigerant through the indoor and outdoor equipment, allowing that refrigerant to absorb heat from the house and carry it outside. Without compressor operation, refrigerant cannot circulate as required. The system may continue moving air, but it cannot complete the heat-transfer cycle needed to cool the property. Several conditions may stop the compressor from starting. An electrical component may have lost strength, a safety device may have opened the circuit, or refrigerant pressure may be ...

Why Does My Air Conditioner Freeze During Summer?

Image
Ice on an air conditioner during a Texas summer may seem impossible. However, a frozen AC is a common warning that the system is not receiving enough airflow, maintaining the correct refrigerant pressure, or transferring heat properly. Homeowners may first notice that less air is coming from the vents. The system may run longer without making the home comfortable, and some rooms may feel warmer than others. Frost may then appear on the copper refrigerant lines, or the evaporator coil inside the indoor unit may become covered with ice. The evaporator coil plays an important role in the cooling process. Warm air from inside the home moves across the coil, where refrigerant absorbs the heat. The blower then sends the cooled air back through the ductwork. For this process to work, the coil needs a steady supply of warm airflow. It also needs the refrigerant to remain at the correct pressure. When airflow becomes restricted or refrigerant pressure drops, the evaporator coil can become colde...

How Long Can an Air Conditioning System Last?

Image
An air conditioner does not need to break down completely to show that it is getting older. In many homes, the signs appear slowly. The unit may need more time to cool the house, run for longer periods, leave certain rooms uncomfortable, or cause electricity costs to increase. When these changes become noticeable, homeowners often begin asking how many years an air conditioning system is supposed to last. Most central air conditioners provide approximately 12 to 17 years of service. This range is useful for planning, but it should not be treated as an exact expiration date. Some systems fail sooner because of poor installation, incorrect sizing, restricted airflow, heavy use, or neglected maintenance. Others continue operating for close to 20 years because they were installed correctly and cared for consistently. The local climate also matters. Lewisville homeowners depend heavily on their cooling systems throughout long North Texas summers. More operating hours mean more wear on the c...
