Air conditioner repairs are not always a result of damaged components. Repairs are regulatory when ensuring the projected lifespan of a unit. However, as a homeowner, you’re most likely curious about how, why, and when air conditioners need repairs. Don’t worry! More often than not, AC problems are to be expected when units have been working for a number of years.
To clarify the importance of AC repairs, our specialists have listed the key reasons air conditioner repairs may be necessary. In Hawaii, air conditioners typically run year-round. So, it’s no surprise why a homeowner should have their system inspected—or even require AC repairs from a professional—every once in a while. Here you will find the top problems that may require professional air conditioner repairs.
Top 5 Air Conditioner Problems
1. Refrigerant Leaks
Sometimes, AC units begin to run low on refrigerant. It should be noted that this depletion of coolant isn’t the result of normal AC processes. Low refrigerant levels are often a result of leaks or undercharging during the installation process. If your system is experiencing a leak, adding more refrigerant is never a sound solution. The leak will ultimately need to be fixed and the AC system itself will need to be recharged.
It’s important to utilize the expertise of a trained and licensed AC technician near you who can identify the issue, fix the leak, inspect refrigerant lines, and properly charge the air conditioning unit with the appropriate amount of coolant. Your system should never be undercharged or overcharged with refrigerant, which is why this process is best left to HVAC experts.
2. AC System Corrosion
It’s no “shock” that when wires and other components are exposed to high levels of vapor or moisture, they are prone to corrosion. Don’t worry, this exposure will not be a cause for any immediate safety concerns. Instead, this exposure will cause your AC to struggle to reach optimal efficiency due to the effect corrosion has on the terminals and wires of your unit.
In some cases, corrosion may cause your system to come to a complete stop altogether. While corrosion isn’t a dangerous issue to deal with, it’s still best practice to leave relevant repairs to a professional HVAC technician.
3. Clogged Drains
When your unit is functioning normally, it removes moisture from the air and disperses it via drain lines. Moisture then drips into the pan underneath the AC unit, and eventually travels down a pipe that drains the excess moisture outside of your home. If your pan is full or the drain has become clogged, the condensation can accumulate and begin to overflow. This can damage floors or ceilings, and even stop your system from cooling altogether.
4. Dirty Air Filters
Air filters should be changed at least once a month to ensure proper airflow and avoid any health problems, ranging from trouble breathing to dizziness and headaches that result from inhaling debris. Too much debris coating or lining specific components of your unit can reduce system efficiency. Air blowing through dirty filters can even pump dirt, dust, pollen, and dander into your home, causing poor indoor air quality. If you’re unsure or uncomfortable about changing or cleaning your filters, an experienced HVAC technician can clean or replace your filters during a tune-up for optimal efficiency.
5. Frozen Evaporator Coils
Evaporator coils in an air conditioning unit are responsible for capturing hot air. These condenser coils require warm air circulating around them in order to avoid freezing over. Too much cold air on the evaporator coils will create ice buildup, which can be harmful to your AC unit’s efficiency. It’s best to have frozen coils diagnosed and treated by a professional in air conditioning system repairs.

You may be thinking to yourself, “Why is my air conditioner icing up?” Don’t worry, it’s completely normal! Well, maybe not “normal”, but ice accumulating on an air conditioning unit is a common occurrence, and AC system repairs can address the problem. You aren’t the first or the last person with a frozen AC.
Our specialists have discussed the common causes of air conditioner freezing and how to repair it. The following guide can help you understand how and why a buildup of ice accumulates on an air conditioning system—and how to resolve it. Let’s get into it!
What Causes an AC Unit to Ice Up?
Ice forming on an air conditioner may initially draw some concern. However, it often points to a common problem that most AC units experience in their lifetime. A block of ice on the AC system in your home occurs when a component of the condenser isn’t getting enough hot air coming in to maintain a proper temperature. This leads to freezing. This issue typically forces an HVAC system to work harder to cool. As a result, it is a waste of energy and ultimately leads to poor AC performance (and indoor discomfort).
Low Internal Temperatures
Air conditioners ice up when the temperature in the condenser’s evaporator coil drops too low. The air intake should normally be receiving warm air and sending it outside of your home. Systems freeze when the flow of this hot air stops. Thus, instead of removing hot air from your home, the evaporator coils end up transferring air that is too cold. This results in ice buildup on the air conditioner.
Other Causes of Ice Forming
Another culprit of an air conditioner icing up is a dirty air filter. When your HVAC system has a clogged air filter, the result is restricted airflow. A lack of refrigerant is another common contributing factor to icing, as well as dirty coils or broken blower fans within the system itself. Technicians typically check HVAC systems during regular maintenance visits for these factors, but there are ways to address these issues on your own.
Resolving AC Icing
Changing or cleaning air filters to remove blockading debris is one solution to air conditioner icing. However, if you routinely clean your filters and have no debris blocking the airflow, you may need to consider other methods for resolution.
Removing any obstruction to airflow such as curtains, blinds, and furniture is another common solution that will prevent air conditioner freezing. In terms of AC repairs, it is best to leave most practices to qualified HVAC technicians.
A professional HVAC technician will often clean the dirty evaporator coil, replace air filters, clear return vents, inspect the blower motor, or repair fans depending on the culprit of the icing. Ensuring proper airflow is crucial to avoiding icing/freezing. In some cases, technicians find low refrigerant and will fix any leaks before returning refrigerant levels back to normal.
How Air Conditioner Icing Wastes Energy
Icing and freezing of an AC unit often go hand-in-hand with skyrocketing energy bills. Air conditioners need to work overtime and deliver poor performance when components of the unit, like the coils or fan, are dirty, damaged, or frozen. This puts a lot of stress on the unit and can significantly reduce its lifespan. More often than not, increased energy bills can result in higher costs than air conditioner repairs—when the problem is left unresolved. It’s best practice to contact a professional HVAC technician immediately if your unit is frozen or you noticed a refrigerant leak. That’s where we come in!

Is your AC blowing warm air? If so, you are not alone! This is a widespread occurrence resulting from various issues and malfunctions that negatively affect your HVAC system. However, a faulty AC can lead to miserable and sweaty nights when you already live in a hot climate.
For this reason, it is essential to reach out to your maintenance team so that a technician can administer the proper AC repairs and get your HVAC system back to running as usual. Here are several possible causes for your AC not blowing cold air. Fortunately, you can avoid most issues by conducting routine maintenance.
Low Refrigerant Levels
The most likely explanation for your air conditioner blowing out hot air is a decrease in refrigerant levels. Refrigerant is the chemical that cools the air blowing out of your vents. Unfortunately, low levels of refrigerant are usually caused by a leak somewhere in your HVAC system. In this instance, it becomes impossible for your AC to produce cool air, and therefore, you must contact a technician to patch the leak and refill the refrigerant.
Anytime the filters in your AC become clogged, the quantity and quality of air decrease significantly. Typically, clogged filter results not from a build-up of dust and debris but rather from a foreign object lodged within the filter. To compensate for the lack of airflow, your AC will work overtime, which can damage the compressor, and the overall result will be hot air.
While this may seem obvious, if your AC is blowing out hot air, you should first check and make sure that the set temperature is not too high. If it is set to a low temperature yet the air continues to blow hot, there could be an electrical error within the thermostat itself. Such errors can cause electrical signals sent by the thermostat to fail, leading to a constantly high temperature. Generally, if your thermostat is to blame, you will need to schedule a maintenance appointment to install a replacement.
Loss of Compression
A faulty compressor can also be the cause of your AC blowing hot air. The sole responsibility of the compressor is to compress the freon within the refrigerant to produce cold air. If there are insufficient refrigerant levels or if the compressor is malfunctioning, the result will be hot air.
We recommend purchasing a brand new compressor rather than conducting repairs, which can be pretty expensive. Your technician will be able to install the new compressor, and you can rest assured that your AC will produce cold, refreshing air for the years to come.
Other Electrical Malfunctions
If you have already checked your refrigerant levels, filter, thermostat, and compressor, then some other electrical error must be causing your AC to blow only hot air. Other electrical malfunctions include blown fuses and problems with the circuit breaker.
Of course, you should never attempt to try and fix electrical malfunctions yourself. Instead, leave all AC repairing to the professionals by calling your servicing team and scheduling an appointment.
