Dealing with a malfunctioning AC unit can be frustrating, especially during peak summer months. To make sure your air conditioning system runs smoothly, it’s important to avoid some common pitfalls that can occur during repair. Here, we’ll explore easy-to-understand, practical strategies to help you sidestep these issues and keep your AC in top shape.
1. Neglecting Regular Maintenance
One of the biggest mistakes is skipping routine maintenance. Regular check-ups can prevent minor issues from becoming major problems. Simple tasks like changing filters and cleaning vents go a long way in maintaining efficiency. It’s surprising how much dust and debris can accumulate in such a short time, blocking airflow and making your unit work harder than it should. A clean system is an efficient system, and keeping up with these small maintenance tasks can extend the life of your AC unit significantly.
Consider creating a maintenance schedule that covers all aspects of your AC unit. Clean the filter every one to two months, and have a professional inspect your system at least once a year. During this check-up, a technician can spot issues like worn-out parts or potential refrigerant leaks early on, saving you the trouble and expense of a major repair in the future. If you’re in doubt about how often your specific system needs maintenance, don’t hesitate to reach out for expert advice.
2. Ignoring Strange Noises
Unusual sounds coming from your AC unit should never be ignored. These noises can be an early warning sign of serious mechanical issues. Address them promptly to avoid costly repairs down the line. Whether it’s a persistent click, a loud rattle, or an unsettling hum, these sounds indicate that some components might be loose, come out of alignment, or be experiencing wear and tear. Regularly listening and responding to these audible signals can mean the difference between a quick fix and a complete system overhaul.
To spot these problems before they escalate, become familiar with the normal operational sounds of your AC system. Once you know what’s normal, you can easily detect when something’s off. For persistent issues involving strange noises, enlisting a professional can be incredibly beneficial. They can diagnose and repair the source of the noise, ensuring your unit operates smoothly and without hiccups.

3. Incorrect Thermostat Settings
Setting your thermostat incorrectly can lead to inefficient cooling and higher energy bills. Make sure your settings reflect the real needs of your home, and consider upgrading to a programmable thermostat for better efficiency. Many homeowners are unaware that setting the thermostat too low can cause your system to work overtime, leading to wear and higher electricity usage. The Department of Energy recommends keeping your home at 78°F while you’re home and raising it when you’re away during the day, which optimizes both comfort and cost-efficiency.
Programmable thermostats are a great investment, allowing you to tailor your cooling needs based on your lifestyle and schedule. For instance, you can have your AC turn on just before you arrive home, ensuring a comfortable environment without wasting energy all day. Many modern thermostats can also be controlled remotely, providing even greater flexibility and control.

4. Overlooking the Outdoor Unit
The outdoor unit of your air conditioner is just as important as the indoor components. Make sure it’s free of debris, leaves, and other obstructions that can impede airflow and reduce efficiency. It’s easy to forget about this external component, especially if it’s tucked away in the side yard. Yet, ensuring there’s at least two feet of clearance around the unit can significantly enhance its performance and longevity. Overgrown shrubs or trees can restrict airflow, leading your system to consume more energy to cool your home.
Spend some time each month inspecting the area around your outdoor unit. Ensure that plants are trimmed back and any debris is cleared away. Additionally, during seasonal changes, it’s helpful to clean any built-up dirt or grime from the unit itself using a gentle spray from your garden hose. This simple yet effective maintenance ensures the unit can efficiently do its job year-round. Keeping this part of your AC system in mind can prevent future headaches and costly repairs.
5. Attempting DIY Repairs Without Knowledge
While DIY repairs can seem cost-effective, they can lead to bigger problems if not done correctly. Unless you’re skilled in AC repair, it’s best to leave complex repairs to trained professionals. Attempting to fix electrical or refrigerant issues without proper training could result in damaging the system further or, worse, personal injury. Additionally, incorrect handling of refrigerants or other components can violate environmental regulations and lead to fines, compounding the costs of repairs. DIY efforts are best limited to basic maintenance tasks, like cleaning filters or coils.
It’s understandable to want to save money by handling repairs on your own, but it often pays to call the pros for anything beyond basic maintenance. Professionals have the expertise to quickly diagnose and repair issues, ensuring the job is done right the first time. Not only does this give you greater peace of mind, but it also prolongs the life of your AC unit.

6. Not Checking Refrigerant Levels
Running an AC unit with low refrigerant levels can severely damage the compressor. Make sure to check levels regularly and recharge them when necessary to maintain optimal cooling performance. Low refrigerant levels often go unnoticed until they cause significant damage, potentially leading to costly replacements. If you notice that your AC isn’t cooling as effectively or it cycles on and off more frequently, it might be a sign of low refrigerant. A professional can safely check and, if necessary, add refrigerant to your system, preventing overheating and prolonging its lifespan.
Interestingly, refrigerant levels do not decrease simply through usage; any loss often indicates a leak, which requires immediate attention. Special tools are used by professionals to detect and fix these leaks effectively. Remember, keeping your AC unit in good working order by ensuring proper refrigerant levels saves energy and maintains your indoor comfort. Consult an expert for accurate refrigerant assessments tailored to your specific system’s requirements.
7. Forgetting to Clean the Coils
Evaporator and condenser coils collect dirt over time, which can reduce the efficiency of your AC system. Regular cleaning or replacing can keep your unit running smoothly. Dirty coils impede efficient heat exchange, forcing your compressor to run longer and work harder. This can unnecessarily inflate your energy bills. With the right maintenance routine, you can keep your coils clean and significantly improve your system’s performance. Coils should be inspected and potentially cleaned annually, depending on environmental factors, like nearby traffic or pollution.
An easy way to clean coils is by using a soft brush or a vacuum cleaner with a brush attachment, ensuring you don’t flatten the coil’s fins. However, for a thorough clean, it might be worthwhile to hire a professional who can manage the cleaning thoroughly while assessing for any additional issues. Migrating dirt can be minimized by keeping the surrounding areas clear of dust and debris and maintaining proper airflow around the unit.

8. Not Sealing Leaks in Ductwork
Leaky ducts can let cool air escape, leading to higher energy bills and inefficient cooling. Regular inspections and sealing of ductwork can help prevent these issues. Ductwork is an often-overlooked component of AC systems, but it’s vital for effective cooling. Gaps, holes, and poor connections can cause significant air loss, reducing overall efficiency. These leaks make your system work harder and can create uneven cooling throughout your home.
Detection and sealing of leaks is something best left to the professionals who have the tools and materials to ensure a long-term solution. While homeowners can check visible ductwork for obvious signs of wear, a comprehensive attic or basement inspection may be needed to identify hidden leaks. Professional sealing services often employ mastic sealant or metal-backed tape for durable repairs. Ensuring your ducts are in good condition maximizes cooling efficiency and keeps your energy expenses under control.
