With summer just around the corner here on Maui, having an air conditioning system that works properly is a must. The summer heat can be unbearable to most and if your ac unit goes out it can be even more uncomfortable.  Repairs can be costly, so it’s important to make sure your air conditioner is in tip-top shape through regular upkeep. However, you want to make sure that  repairs and maintenance upkeep is done by a certified HVAC contractor.


A clogged or dirty filter is one a common reason that an air conditioning unit will not work properly. The manufacturer provides suggestions on how often to change your ac units air filter. It can be monthly, every three months or you may have a filter that is reusable and needs to be cleaned as soon as they get dirty. To determine if a filter needs to be cleaned is to check if light passes through it, if it doesn’t then it’s time to clean the filter. A dry filter reduces the flow of air but it can also cause the unit to freeze.


Turn on your thermostat to make sure it’s clean, on the correct setting and that it’s not being affected by sunlight. If you notice it’s not working as it should, schedule an appointment with your HVAC certified technician.

Refrigerant Leaks

If coolant starts leaking in your AC unit, it will not work properly and the temperature will fluctuate. Where the leak is located will determine the cost of repairing it, so you want to be sure the ac unit is examined every year by a trained HVAC technician.


A ac units drain line can become clogged with not only dirt but dust and list, just like the filter. The drain pan will fill and water will leak out causing potentially serious damage to the AC unit or anything that is nearby.

Breakers or Fuses

To keep an AC unit’s motor or it’s compressor from overheating, the breakers and fuses help to prevent this. An HVAC technician will check the the unit first when the motor stops working.


The motors that give power to an AC units compressor and fans will not work without the capacitors. Since the start capacitors sends a jolt of power to activate the motor and the run capacitor provides a series of jolts to keep it running. If either one of them burns out the AC unit will not run as it should.


The compressor of an AC unit applies energy to the refrigerant and pushes it through the different coils to carry out heat exchange. If a compressor goes out, your Ac unit will no longer cool your home. Also, there’s not enough refrigerant in the compressor, it will start to run hot and will seize. However, on the flip side, if there’s too much refrigerant, then it will return back to the compressor and that can cause it to stop working as well.

Condenser Coils

The condenser coil is located outside with the compressor and can also become dirty or clogged due the outside elements.  Usually, you can use a water hose to clean it once a year, but if they are neglected and get too dirty, you will need to contact an HVAC technician to use a chemical cleaner.
