Some common problems that can cause an air conditioner to not cooling in Connecticut homes:

  • Improper installation – A poorly installed unit may have airflow issues, duct leaks, or incorrect sizing, all of which reduce cooling efficiency.
  • Dirty or clogged air filters – When filters are dirty or not functioning properly, airflow is restricted, reducing the system’s ability to cool your home.
  • Blocked or clogged condenser coil – A dirty coil prevents heat from being released outside, making the system work harder and cool less effectively.
  • Frozen evaporator coil – Often caused by restricted airflow or low refrigerant levels, this can stop the system from cooling entirely.
  • Refrigerant leaks – Low refrigerant means the system can’t absorb heat properly, leading to weak or warm air coming from the vents.
  • Compressor malfunctions – Since the compressor circulates refrigerant, a failure here can prevent the system from cooling altogether.
  • Faulty thermostat – If your thermostat is broken, miscalibrated, or located in a poor spot, it may not signal the AC to cool properly.
  • Leaky or poorly insulated ductwork – Conditioned air can escape through holes or loose connections, reducing the system’s efficiency.
  • Electrical or sensor problems – Faulty wiring, blown capacitors, or sensor issues can disrupt the AC’s ability to function correctly.
  • Aging system – Older units lose efficiency over time and may struggle to cool effectively, especially during hot or humid Connecticut summers.
  • Outdoor unit obstructions – Leaves, debris, or plants crowding the condenser unit can block airflow and reduce cooling power.
  • Undersized AC unit – If the air conditioner is too small for the space it’s cooling, it will constantly run without adequately lowering the temperature.
