Some of the more “typical” repairs we see in Climatech of Professional Air are faulty capacitors and contactors. A large amount of electricity flows through these components, creating the possibility of both of them getting very hot. When the outside temperature rises, these components generate even more heat and, as a result, they frequently fail, and it doesn't seem to matter the make or size of the unit. If you are in need of Commercial Refrigeration Service near Charleston SC, the good news is that both capacitors and contactors aren't usually very expensive to repair. It's worth the investment to repair it.
Another common fault we see is in the condensing fan motor. This is the fan located in the air conditioner. It withstands extreme temperatures all year round, as it is exposed to external elements. Despite the elements, the industry has come a long way in developing systems and components that can stand the test of time.
Fan motors are also an investment worth replacing. Dirty equipment can also cause problems with the system. Dust and other particles suspended in the air often accumulate in the condensing coil of the air conditioner, reducing efficiency and capacity. In severe cases, the unit may even freeze due to a dirty condensing coil.
This means that ice will form around the copper lines, either inside or outside. As the air conditioner draws air through the condensing coil, it's much more effective to clean it from the inside out. To do this, you must remove the top or side panel. We suggest that homeowners do not try this, as both air conditioning and heating switches must be turned off. Call a certified HVAC professional, such as Climatech from Professional Air, to perform the repair.
Please note that all of the listed faults and repairs must be addressed by a professional HVAC technician. Since these are high-voltage electricity and refrigerant, it is not recommended that homeowners attempt to carry out these repairs for their own safety. Refrigerant handlers must also be certified by the EPA. One of the main reasons people have problems with air conditioning is because the air filter is dirty.
This is very common and easy to prevent. A dirty filter restricts the amount of air flowing through the evaporator coil. When this happens, the coil gets too cold and the system freezes. Changing the filter once a month is the best line of defense. A clogged condensate drain can cause water to build up inside the unit and affect its ability to regulate temperature.
This can also damage other components, such as evaporator coils. An electrical fault can be caused by damaged contactors, cables, and fuses. Acids can build up in the system as a result of electrical problems and cause other parts of the system to malfunction. Power outages can also cause electrical problems in the air conditioning unit.
Finken offers maintenance plans that include testing filters to maintain your system working cleanly. When temperatures rise, air conditioning systems in commercial and industrial facilities work overtime to maintain comfortable and compliant environments. However, high demand comes with high risk. Summer is the most common season for air conditioning-related emergencies, especially in older or high-demand systems.
For managers of healthcare, manufacturing, or commercial facilities, a heating, ventilation and air conditioning system failure in mid-summer can quickly go from being inconvenient to catastrophic. The main culprits are compressor failures, frozen coils, clogged drains, worn belts and dirty filters, all of which can be prevented with regular service. The compressor is the heart of your HVAC system and is under maximum stress when there is a lot of heat and humidity. A low coolant level, electrical problems, or dirty coils can cause it to overheat or get stuck.
Ironically, coils can freeze in extreme heat if airflow is restricted or coolant levels are restricted are low. Dirty filters or clogged ventilation grilles are the most common culprits. Restricted airflow, a low coolant level, or prolonged uninterrupted system operation can cause ice to form in the coils, even in the midst of a heat wave. Condensate lines remove moisture from the system.
In summer, excess moisture and dust can clog these lines and cause water leaks and system shutdowns. If left unaddressed, water damage can affect electrical components and cause indoor air quality problems, especially in healthcare settings. Belts wear out faster if used constantly, and engine components can overheat or jam without regular lubrication and inspection. Dust, pollen, and dirt build up quickly in the summer months, reducing efficiency and increasing strain on the entire system.
Look for reduced cooling performance, inconsistent temperatures, strange noises, bad odors, and increased utility costs, all indicators that your system may be failing. If left unchecked, minor HVAC problems can lead to system-wide failures, production downtime, costly repairs and, in healthcare environments, potential compliance violations due to temperature-sensitive conditions. Scheduling preventive air conditioning maintenance is critical, but it's important to have a plan when faced with an air conditioning emergency.
