There are many things that can go wrong with your AC, and while DIY repairs can help in the short term, it’s best to call in a professional for issues involving electrical components, refrigerant, or major components like compressors. Attempting to replace or troubleshoot these parts without the proper training could cause further damage to your system, and can result in even bigger repair bills down the road.
Common AC parts that are prone to wear and tear include the capacitors, compressor, evaporator coil, fan motor, and thermostat. Unusual noises, poor airflow, or high electricity bills all signal that these components are failing and require repair or replacement. Preventive maintenance can help catch these issues early on, and can save you money by extending the life of your AC unit.
Capacitors are the brains of your AC, providing energy to start and run motors within the system. This electrical component is prone to wear and tear due to age, heat exposure, and other factors, but replacing it as soon as you notice signs of failure can prevent a full AC breakdown. A common sign of a failing capacitor is a buzzing sound, and it’s also possible to spot the issue by checking for swollen or leaking caps.
The compressor pumps refrigerant through your AC unit, ensuring that it circulates throughout the home. If the compressor fails, your home will suffer from a lack of cool air, and a clogged condensate drain line can lead to water leakage and damage.
Your AC’s blower and fan motors both play critical roles in your system, helping to circulate air through your ductwork and release heat outdoors. These components are also prone to wear and tear, and can be damaged by poor lubrication or electrical issues. Regular yearly maintenance services can prevent these issues from developing, and ensure your system is running efficiently.
The thermostat controls all aspects of your AC’s operation, from cycling to determining the optimal temperature in your home. This is a highly sensitive and complex piece of equipment, and can be easily damaged by physical damage or electrical issues. A skilled AC technician can inspect and test the thermostat to see if it’s functioning properly.
Electrical Issues
The electrical wiring that powers an AC unit can become damaged over time. This can lead to a number of issues, including insufficient voltage. Often, these issues cannot be resolved without professional assistance, but some homeowners may be able to troubleshoot AC electrical problems themselves. Incorrect handling of electrical wiring can cause serious injury or damage to your AC system.
One common electrical issue is a tripped circuit breaker. This can happen if you’re using too many appliances at once, or if there are power surges after a storm. To reset the breaker, locate it in your home’s electrical panel and flip it off and then on again. If the breaker trips again, you should call an electrician to check for electrical damage.
Another possible electrical issue is a capacitor that’s not functioning properly. Capacitors are responsible for regulating the flow of current to critical motors like the compressor, condenser fan motor, and blower motor. Over time, they can wear out and fail due to regular use or manufacturing defects. If you suspect a capacitor problem, there are a few things you can try.
You can start by examining the capacitor for signs of bulging, which is a sign of failure. You can also check for broken internal connections by gently tugging on the capacitor. Loose connections can reduce the efficiency of your air conditioning system and increase its energy costs.
A blown fuse or tripped breaker can also indicate a problem with your AC’s electrical system. In some cases, this problem is caused by a dirty air filter that restricts airflow. Other times, it’s an indication that the thermostat is inaccurate and needs to be replaced or calibrated. Other signs include increased energy bills and cold air coming out of only certain vents.
A clogged air filter, blocked vents, or low refrigerant can all cause an AC to stop working properly. However, in most cases, this is an indicator of a more serious electrical or mechanical problem that requires professional repair. Taking care of electrical problems yourself is possible, but it’s important to recognize when your DIY repairs go beyond your expertise. Attempting to repair complex AC electrical issues could exacerbate the problem and lead to costly equipment damage.
Drainage Issues
As your AC runs, it generates condensation on its evaporator coils. This excess moisture drips off into a condensate pan and exits the system through the drain line. Unfortunately, humidity isn’t the only thing left behind on those coils; dust and dirt often move down the drain line too, where they can clog it. Our professional technicians can quickly clear any clogs, allowing water to flow freely.
When you notice water pooling around your air conditioner unit or noticing musty smells, it’s likely a sign of a drainage issue. Whether that means a disconnected drain line or a clogged condensate drip pan, it’s important to take action before the problem escalates.
Clogged drain lines can also cause condensation to build up on your ductwork or inside the AC unit itself, leading to leaks and a host of other issues that can damage your home and lower your system’s performance. That’s why it’s so important to stay ahead of these problems with routine maintenance from our trained technicians.
The first step to fixing any drainage issue is to shut off the unit. This will allow the water currently being dispersed to your home to stop and prevent any electrical shock or damage to your unit. Next, locate the drain line outside of your house. This is typically a PVC pipe that runs from your AC unit to the outdoors. If you have trouble finding it, refer to your owner’s manual or ask a trusted friend for assistance.
Once you’ve found the drain line, look for any signs of a clog. If you notice a grating sound, it’s usually a sign that air bubbles are trapped inside the clogged drain line. Using a wet/dry vacuum or flushing the line with a mix of warm water and vinegar should help you remove the clog and restore proper drainage. For more serious clogs, our technician may need to cut and inspect the drain line directly. Our team will always be honest and upfront with you about what needs to be done to fix the issue and prevent it from coming back in the future.
Thermostat Issues
The thermostat is a vital part of your air conditioning system. It controls everything from the fan speed to the compressor. If your thermostat is not working properly, the entire system can suffer. Recognizing signs of thermostat problems early can help you avoid expensive AC repairs or replacement.
One of the most common thermostat issues is when it fails to maintain its temperature settings. This can be caused by a number of factors. For example, the thermostat may be old and worn out. It could also be placed in a position that affects its accuracy, such as being near a heat source or direct sunlight. If you suspect that this is the case, our technicians can help you move your thermostat or simply cover it with a towel to prevent direct sunlight from heating it up.
Another reason that the thermostat might fail to maintain its temperature setting is because of a malfunctioning sensor or faulty wiring. If you’ve noticed that your thermostat isn’t performing as it should, it’s worth testing the sensors and wiring with a multimeter. This will allow you to see if any of the components are defective or damaged and determine what needs fixing.
A clogged air filter can also cause the thermostat to malfunction. The problem is that it prevents the system from being able to remove heat from your home effectively, and that can lead to insufficient cooling. Changing the air filter can usually solve this issue, although we recommend changing it every one or three months to ensure that your AC is working as efficiently as possible.
Other common thermostat issues include problems with the capacitors, which are responsible for starting the fan and compressor motors. Over time, they can wear out and require replacement, and this is a job that only an HVAC professional should handle due to the high voltage involved. In addition, if the AC is leaking or producing unpleasant odors, low refrigerant is often the culprit and requires a recharge. This is another job that should be left to a trained technician, as handling refrigerant can be dangerous and cause serious injury or even death.
