In this blog post, we’ll provide you with five helpful tips for air conditioning repair in Phoenix, Arizona.

1) Check for Power Supply Issues  

Before calling for commercial air conditioning services, it’s essential to check your commercial AC unit’s power supply. If it’s not receiving adequate power, it won’t function correctly, which means it won’t be blowing cold air.

Begin by inspecting your AC unit’s circuit breaker and making sure it hasn’t tripped. If it has, switch it off and back on again to see if that restores power. If it trips again, call in a professional commercial air conditioner repair company for further investigation.

If your circuit breaker is not the issue, check the power switch located on the outside unit of your air conditioning system. Make sure it is in the “on” position and that it is receiving power. If it still doesn’t work, check the fuses located in the outside unit’s disconnect box. If a fuse is blown, replace it.By ensuring your AC unit’s power supply is functioning correctly, you may avoid costly commercial air conditioning repairs. If your AC unit still doesn’t work after checking the power supply, contact a reliable commercial air conditioning repair service to schedule an appointment.

2) Inspect the Thermostat Settings  

The thermostat is the control center of your commercial air conditioner. It helps to maintain a consistent temperature inside your commercial building. A malfunctioning thermostat can cause your air conditioner to stop working properly. If your air conditioner is not blowing cool air, the first thing to do is to check the thermostat settings. Make sure that it is set to “cool” and the temperature is set lower than the room temperature.

If your thermostat is not functioning properly, you may need to call in a professional for commercial AC repair. Faulty thermostats can be tricky to diagnose, so it is best to leave the job to an experienced technician. They will be able to troubleshoot the issue and recommend a course of action.Regular maintenance and inspection of your HVAC equipment, including the thermostat, is key to preventing breakdowns and costly repairs. A reliable commercial HVAC service provider can help you with commercial AC installation, commercial heating, and other HVAC services. Don’t let hot air ruin your business day. Schedule a routine maintenance check today.

3) Clean or Replace Air Filters  

The air filters in your commercial air conditioner are responsible for keeping your indoor air clean and free of pollutants. Over time, these filters can become clogged with dust, dirt, and debris, reducing the efficiency of your air conditioning unit and leading to increased energy bills. To prevent this from happening, it is recommended that you clean or replace your air filters regularly.

If you have washable air filters, you can clean them by simply rinsing them off with water and letting them air dry. For disposable filters, it is best to replace them every three months or as recommended by the manufacturer.

Regularly cleaning or replacing your air filters not only improves the efficiency of your air conditioner but can also improve the air quality of your indoor environment. By keeping your air filters clean, you can reduce the amount of allergens, bacteria, and other pollutants that circulate throughout your building.

So, don’t forget to include cleaning or replacing your air filters as part of your regular commercial air conditioner maintenance routine.

4) Check for Refrigerant Leaks  

Refrigerant is a vital component of your commercial air conditioner as it helps in cooling your facility. However, if there’s a leak in the refrigerant, your commercial ac units won’t function effectively and will need repairs or replaced. A refrigerant leak is a common problem faced by many businesses in Arizona, and if left unattended, it can cause severe damage to the system. Signs of a refrigerant leak include warm air coming from the vents, frozen coils, and strange hissing or bubbling sounds.

To check for a refrigerant leak, a qualified technician will need to inspect the system. They may use a leak detection kit, pressure gauges, and other specialized tools to identify the problem. Once the leak is found, they will repair the damaged component or replace it if necessary.It’s crucial to address refrigerant leaks as soon as possible to prevent more significant problems in the future. By doing this, you can avoid costly repairs or even the need to replace your commercial HVAC system altogether. So, if you suspect that your commercial air conditioner has a refrigerant leak, don’t hesitate to contact a certified professional for immediate repairs.

5) Inspect the Condenser and Evaporator Coils.  

The condenser and evaporator coils play a critical role in your commercial air conditioner’s cooling process. Over time, these coils can become clogged with dirt and debris, leading to reduced airflow and poor performance. It’s important to inspect these coils regularly and clean them as needed to maintain optimal efficiency.

To inspect the coils, start by turning off the power supply to the air conditioner. Next, locate the outdoor unit and remove the top cover to access the condenser coils. Using a soft-bristled brush or a special coil-cleaning tool, gently remove any dirt or debris that has accumulated on the coils. Repeat the same process for the indoor unit to access the evaporator coils.

If you notice any damage or corrosion to the coils, it’s important to contact a professional technician for air conditioner repair. Ignoring this issue could lead to further damage and potential system failure.By inspecting and maintaining your air conditioner’s condenser and evaporator coils, you can extend the life of your unit and ensure efficient cooling for your commercial space.


If you’re experiencing issues with your commercial air conditioner, don’t panic. With these five tips, you’ll be able to troubleshoot and address many common problems on your own. By checking for power supply issues, inspecting thermostat settings, cleaning, or replacing air filters, checking for refrigerant leaks, and inspecting condenser and evaporator coils, you’ll be well on your way to a functioning air conditioner.

Of course, some problems may require professional help. When in doubt, don’t hesitate to call in an experienced HVAC technician to diagnose and repair any complex issues.
