Common AC Problems and Their Causes
At Alder Plumbing Heating and Air, we understand that a properly functioning air conditioner is vital for comfort in Fort Collins and Loveland. Here's an expanded look at common AC issues to help you identify and address problems promptly.
-
Not Cooling Properly
- Dirty Filters: Accumulated dirt and debris in filters hinder air flow and cooling efficiency. This can cause the evaporator coils to freeze, blocking the cool air and potentially leading to system damage. Regular filter cleaning or replacement is crucial for maintaining air quality and efficiency.
- Refrigerant Issues: Low levels of refrigerant, often due to leaks or age, impair the AC's ability to cool. A precise amount of refrigerant, as per the manufacturer's specifications, is necessary for optimal performance. Leaks not only reduce efficiency but can also harm the environment.
- Sensor Problems: Thermostat sensors monitor and regulate air temperature. Faulty sensors may cause the unit to cycle irregularly or run continuously, affecting comfort and increasing energy bills.
- Thermostat Issues: If the thermostat isn't calibrated correctly or is malfunctioning, it can misread the indoor temperature, leading to overcooling or insufficient cooling. This miscommunication can strain the AC system.
- Drainage Problems: The AC unit's drainage system removes the condensation produced during the cooling process. Clogged drain lines can lead to water leaks, humidity issues, and growth of mold or mildew.
- Dirty Coils: Over time, condenser coils can become coated with dirt, reducing their ability to expel heat. This inefficiency forces the system to work harder, increasing wear and tear and reducing the lifespan of the unit.

Not Turning On
- Electric Control Failure: Frequent usage can wear out the compressor and fan controls. Electrical connections can also become corroded over time, disrupting the AC's power supply.
- Thermostat Failure: A malfunctioning thermostat can fail to communicate with the AC unit, preventing it from turning on. Issues can range from simple battery replacement to more complex wiring problems.
- Faulty Motor: The AC motor powers the fan that circulates air. If the motor fails, the unit will not operate, often signaled beforehand by unusual sounds or decreased performance.
- Dirty Condensers: External blockages like leaves, dirt, or nests can obstruct the condenser's functionality. Regular cleaning of the area around the condenser is important to maintain airflow and system efficiency.
- Lack of Power: Sometimes the issue is as simple as a tripped circuit breaker or a blown fuse. Regularly checking the electrical connections can prevent unnecessary service calls.
- Wiring Problem: Faulty or outdated wiring can pose a significant risk, not just to the AC unit but also to your home's overall electrical safety.

Limited Airflow
- Ductwork Issues: Leaks, blockages, or damage in the ductwork can significantly reduce airflow, making the system inefficient and increasing energy costs.
- Dirty Filters: Filters clogged with dust and debris restrict airflow, diminishing the AC's efficiency and potentially causing health concerns due to poor air quality.
- Obstructed Condenser: Any blockage around the condenser unit can restrict the airflow needed for cooling. Regularly clearing debris and maintaining clearance around the unit is essential.
- Faulty Blowers: The blower fans, driven by motors, circulate air through the system. Problems with these components can lead to inadequate airflow and uneven cooling.
- Oversized AC Units: An AC unit that is too large for the space will cycle on and off frequently. This not only reduces efficiency but also fails to adequately remove humidity from the air, affecting comfort.
- Thermostat Problems: An improperly calibrated or malfunctioning thermostat can lead to inadequate airflow. Simple issues like incorrect settings or low battery power can also affect performance.
