    Incorrect or faulty settings in the thermostat usually result in blowing out warm and unpleasant air out of your AC.

  2. Clogged Air Filters:

    The purpose of air filters is to keep the dust & debris from getting in– so when the air filters get clogged it results in reduced airflow from the AC.

  3. Ventilation Blockage:

    The outdoor units are built to get the cold air pushed out during the colder season and vice versa. The ventilation of the unit gets blocked usually from the debris or leaves– it's an easy fix, by cleaning or removing the blockers.

  4. Frozen Evaporator Coils:

    Evaporator coils are essential for removing heat and humidity to pass cold air to the room. So, when the evaporator coils get frozen up, it is unable to transfer heat effectively, ultimately losing the cooling ability of your AC.

  5. Leaks in the Refrigerant:

    A refrigerant leak causes greater wear and tear on your cooling system as it ages, as well as an increase in energy bills. It is advised to contact the maintenance team ASAP.

  6. Leaky Ducts:

    The system can lose up to a third of its air due to leaky ducts or insufficient insulation, however it can be prevented by properly sealing and insulating the ducts.

    However, blockages around the condenser can put excessive pressure on the AC unit and restrict airflow. Therefore, to ensure an optimal performing AC, keeping at least 2 feet of clear space around the condenser unit is recommended.

  5. Close Windows/Doors for Maximum Efficiency:

    Cool breezes are the best when you’re sitting by the settee and relaxing on a fine after summer afternoon. When you leave your AC on and have the windows or doors opened it allows the cool air produced by the AC to escape. causing the unit to work harder and become more prone to breakdowns and damage.
