Understand Common Air Conditioning Issues

July 19, 2024

Air conditioning systems are essential for maintaining indoor comfort, but they can encounter various problems over time.

Recognizing these issues early can help you avoid major breakdowns and costly repairs. Here are some common air conditioning problems homeowners should be aware of, serviced by Absolute HVAC, covering all of Long Island, NY:


  1. Poor Air Flow: Insufficient airflow from vents can indicate issues with the compressor or ductwork. It might also be due to clogged air filters, which restrict airflow and reduce efficiency.
  2. Refrigerant Leaks: Low refrigerant levels could mean there's a leak in the system. Refrigerant is essential for cooling, so a leak needs prompt attention from HVAC professionals at Absolute HVAC.
  3. Thermostat Problems: Incorrect thermostat settings or a malfunctioning thermostat can lead to erratic cooling cycles or ineffective temperature regulation.
  4. Strange Noises: Unusual sounds like squealing, grinding, or banging could indicate mechanical issues within the AC unit, such as worn-out belts or motor bearings.
  5. Faulty Capacitors: Capacitors start the motors in an air conditioner. When they fail, the unit may not start at all or could experience frequent shutdowns. Absolute HVAC technicians can diagnose and replace faulty capacitors.
  6. Frozen Evaporator Coils: This usually happens due to restricted airflow or low refrigerant levels. Frozen coils prevent the system from cooling effectively and should be addressed promptly by Absolute HVAC.
  7. Electrical Issues: Wiring problems or electrical component failures can cause the air conditioner to malfunction or stop working altogether. Absolute HVAC's expertise ensures electrical issues are resolved safely and efficiently.
  8. Clogged Drainage: If the condensate drain becomes clogged, it can lead to water leaks or moisture buildup, potentially causing water damage or mold growth. Absolute HVAC offers drain cleaning services to prevent such issues.
  9. Dirty Filters: Neglecting to replace or clean air filters regularly can reduce airflow, strain the system, and lead to poor indoor air quality. Absolute HVAC recommends regular filter maintenance to improve efficiency and air quality.
  10. General Wear and Tear: Like any mechanical system, air conditioners experience wear over time. Regular maintenance by Absolute HVAC professionals can help identify and address minor issues before they become major problems.


Being aware of these common air conditioning problems and relying on Absolute HVAC's services can help you take proactive steps to maintain your system's efficiency and longevity. Their comprehensive service coverage ensures residents across Long Island, NY, can enjoy reliable HVAC solutions.
