Common AC Troubles You Should Know: Air conditioning systems are essential for maintaining comfort in homes and buildings, especially during peak summer months. However, like any mechanical system, AC units can develop issues that reduce performance, increase energy bills, and even pose safety risks if not addressed. Whether you’re a homeowner or building manager, recognizing the signs of common AC troubles can help you respond quickly and avoid costly breakdowns.
Below, we break down the most frequent air conditioning problems, why they occur, and how to handle them effectively.
Insufficient Cooling
Symptoms: The AC runs but doesn’t cool the space adequately. Some rooms may be warmer than others.
Causes:
- Dirty air filters blocking airflow
- Low refrigerant levels
- Faulty compressor
- Leaky or poorly insulated ductwork
Solution: Start by checking the air filter—replacing or cleaning it may resolve the issue. If the problem persists, it may require a technician to inspect refrigerant levels or assess duct performance.
Tip: Routine filter replacement (every 1–3 months) can prevent a range of cooling issues.
AC Won’t Turn On
Symptoms: The unit doesn’t respond when turned on or fails to start altogether.
Causes:
- Tripped circuit breaker or blown fuse
- Faulty thermostat
- Electrical issues within the unit
- Capacitor failure
Solution: First, check your power source and reset any tripped breakers. If that doesn’t work, inspect the thermostat settings. If the AC still won’t start, it’s time to call in a licensed HVAC technician for further diagnostics.
Unusual Noises
Symptoms: Unusual sounds like grinding, squeaking, clanking, or rattling during use.
Causes:
- Loose parts or mounting hardware
- Motor bearings wearing out
- Fan issues
- Debris caught in the unit
Solution: Turn off the system immediately to prevent further damage. An expert evaluation can pinpoint the noise’s origin and help avoid serious future damage.
Note: Ignoring unusual noises can lead to major system failures and more expensive repairs down the line.
Refrigerant Leaks
Symptoms: Reduced cooling capacity, hissing sounds, or ice buildup on the evaporator coil.
Causes:
- Corrosion in the coils
- Manufacturing defects
- Vibration-related wear and tear
Solution: Only licensed HVAC technicians should address refrigerant-related problems. Leaks not only reduce efficiency but can also harm the environment if not managed correctly.
Water Leaks or Excess Moisture
Symptoms: Water pooling around the indoor unit or dampness in walls and ceilings.
Causes:
- Clogged or disconnected drain line
- Frozen evaporator coil
- Improper installation
Solution: Unclog the drain line if accessible, but if the problem continues, professional service is needed. Excess moisture may cause mold infestations and damage building structures, particularly in commercial properties.
Frozen Evaporator Coil
Symptoms: Reduced airflow, ice on the outdoor or indoor unit, and eventual system shutdown.
Causes:
- Dirty coils
- Low refrigerant
- Poor airflow due to blocked ducts or dirty filters
Solution: Turn off the unit to let it thaw and inspect for any airflow obstructions. If it refreezes after restarting, contact a technician for a full inspection.
Short Cycling
Symptoms: AC turns on and off frequently without completing a full cooling cycle.
Causes:
- Oversized unit
- Electrical problems
- Dirty filters or coils
Solution: Frequent system starts and stops put strain on the equipment and increase utility bills. Schedule a system evaluation to determine whether sizing or electrical components are at fault.
Thermostat Malfunctions
Symptoms: Inconsistent temperature control or non-responsive settings.
- Causes:
- Aging thermostat
- Miscalibration
- Poor placement (e.g., in direct sunlight)
Solution: Consider upgrading to a programmable or smart thermostat, which can improve both comfort and efficiency. Always ensure it’s installed in a neutral location for accurate readings.
