The air conditioner is your loyal ally in battling the relentless summer heat waves. It’s not rare that ACs break down just when you need it most. And who needs this in Florida, which has a history of some of the hottest months ever recorded? We can only anticipate hotter summers ahead.

Far too many of us have faced this scenario, leaving us in a heated dilemma. But no need to worry. We’ll arm you with knowledge and tips on the perplexing problem of an AC unit that won’t cool and the frustrating mystery of an unexpected shutdown. 

How Does Your AC System Work?

A basic understanding of its components and functionality is crucial to fine-tuning your AC system. At its simplest, an AC system works by exchanging heat. The system uses a refrigerant to absorb indoor heat and expel it outdoors, cooling the air inside your home. 

Essential elements that make this process possible include the following:

  • Evaporator coil – responsible for cooling the air
  • Condenser coil – which expels the heat outdoors
  • Compressor – circulates the refrigerant through the coils
  • Expansion valve – regulates the flow of refrigerant

Once you know how AC systems function, it’s good to learn more about diagnosing and troubleshooting common problems. 

Common AC Problems and Troubleshooting Tips

Ever wonder why your AC acts up just when you need it the most? Well, you’re not alone. Let’s explore some of the most frequent AC frustrations.

Not Cooling Properly

One of the most frequent problems homeowners report is that their AC is not cooling efficiently. Multiple reasons could cause this issue. One widespread problem is dirty or blocked air filters, which can limit airflow and lower the system’s effectiveness. Regularly inspecting and changing your air filters every 1 to 3 months is a simple way to avoid this. 

Another culprit might be low refrigerant levels, which are crucial for cooling. A system that’s running low on refrigerant often suggests there might be a leak. While you can replace the air filters yourself, dealing with refrigerant requires a professional’s touch due to the technical and environmental considerations involved.

AC Unit Not Turning On

If your AC unit doesn’t power on, the problem could be with the thermostat settings, power supply, or a tripped circuit breaker. Ensure the thermostat is on the “cool” setting and that its temperature is set below the room’s current temperature. If the thermostat settings seem fine, check if the batteries need replacing. 

Next, move to your home’s circuit breaker pane. A tripped breaker can be quickly flipped back to restore power to your AC unit. If these steps don’t solve the issue, it could indicate a deeper electrical problem requiring professional assistance.

Unusual Noises

An AC system is expected to operate with minimal noise. Loud, unusual noises such as banging, whistling, or hissing can signal problems. Banging might indicate loose or broken parts inside the AC unit, while hissing sounds could suggest a refrigerant leak. Typically, a professional must diagnose and fix mechanical problems to avoid additional damage to your system.

Water Leaks Inside or Outside

Water leaks can cause concern and usually stem from a blocked condensate drain line or ice on the evaporator coils. You can attempt to clear a clogged drain line using a wet/dry vacuum or flushing it with vinegar. 

Frozen coils, however, can be a sign of low airflow or refrigerant levels and might defrost once the underlying issue is resolved. While some homeowners may feel comfortable addressing a clogged drain line, problems leading to frozen coils typically require professional assessment and repair.

When to Call a Professional

Although tackling some AC issues by yourself can be rewarding, there are occasions when seeking professional help is crucial. An expert’s intervention can save you from future breakdowns, ensuring your AC runs efficiently and safely. 

Below are the clear indicators that you should contact a certified HVAC technician:

  • Refrigerant Issues: If you believe your AC is running low on refrigerant or experiencing a leak, professional intervention is needed. Because of their environmental and safety risks, handling refrigerants necessitates specific expertise and tools.
  • Electrical Problems: Flickering lights, non-responsive thermostats, or an AC that trips the breaker are all signs of potential electrical issues. Professionals must handle electrical diagnostics and repairs to prevent safety risks.
  • Persistent Noises or Odors: If your AC makes unusual noises after troubleshooting or emits strange smells, a professional can diagnose and solve the issue before it worsens.
  • Ice Formation: Ice on your AC’s coils or lines indicates airflow issues or refrigerant problems, which are best addressed by an expert.
  • No Improvement After Basic Troubleshooting: If you’ve tried the basic fixes (like cleaning the filters or resetting the breaker) and your AC is still not performing, a technician can conduct a comprehensive diagnosis to identify and fix the root cause.

Preventive Measures and Regular Maintenance

Taking care of your AC is about preventing them from happening in the first place. Here’s a straightforward checklist to keep your AC in great shape:


  • Change or Clean Air Filters Regularly: This simple step can significantly impact your AC’s efficiency. Aim to check your filters monthly and replace or clean them as needed, usually every 1-3 months.
  • Keep the Area Around the Outdoor Unit Clear: Maintain a minimum clearance of 2 feet around your outdoor unit. This space allows the unit to draw in air smoothly, avoiding overheating and guaranteeing its efficient function.
  • Schedule Inspections: Ensure a qualified HVAC technician conducts an inspection and maintenance service on your air conditioning unit annually. They can catch issues early, clean difficult-to-reach parts, and ensure your system is ready for the season.
  • Ensure Indoor Vents Are Unblocked: Furniture, curtains, or toys blocking the vents can restrict airflow, making your AC work harder than it needs to. A quick walk-through to check vent clearance can make a difference.
  • Check Your Thermostat: Sometimes, the issue may not lie with the AC unit but rather with the thermostat. Verify its proper functionality and contemplate upgrading to a smart thermostat to enhance energy management. 

By incorporating these precautionary steps into your schedule, you’ll prolong the longevity of your AC and enhance its effectiveness and efficiency. Additionally, consistent maintenance can help prevent unforeseen malfunctions during critical moments when you rely most on your AC.
