5 Reasons Why Your A/C Unit Isn’t Functioning Properly

When the A/C fails to work, begins leaking, makes strange noises, or isn’t cooling effectively you can find yourself in a state of panic. If you encounter a problem like this, it’s best to call an HVAC technician. Listed below are 5 reasons why your A/C unit could be having these problems:

1 – The A/C unit is not blowing air – The most likely cause of this situation is that the belt connecting the air handler motor and blower is broken or damaged.

2 – The condenser isn’t running – A fuse may be blown or there may be a tripped breaker –  A central air conditioner should be on a dedicated 240-volt circuit. You can reset the breaker by turning it off then on again. Otherwise, the fuse may need to be replaced. Another cause of this is the thermostat isn’t set properly. There could be a faulty motor or compressor.

3 – A/C unit turns on and off at random times – This is something that happens when the unit has not been cleaned in a while. The condenser or evaporator unit could be blocked or broken.

4 – If the air conditioning unit is not cooling properly, the drain pipe may be clogged by algae and/or a leak can be occurring around the area of this drain pipe. Another issue may be a dirty evaporator or an improperly sized air conditioner.

5 – Air unit runs but does not cool – Check the thermostat and the compressor. The compressor might be blocked by plants or other debris. You may have a faulty compressor or not enough refrigerant in the system.
