Outside AC Unit Not Working? Here’s How to Troubleshoot It

When it comes to staying cool during the summertime in Lafayette, the outside air conditioning condenser is a critical piece of equipment. But when the outside unit isn’t working, you’ll find your home can quickly become an unbearable environment. Since the condenser is responsible for lowering the temperature of refrigerant and dispersing it inside the home, it’s important to understand what’s causing the unit to malfunction so you can get it running again. Here’s what you need to know when the outside unit of your AC isn’t working properly.

What is an AC condenser?

An AC condenser is an important part of an air conditioning system. It is responsible for transferring heat from inside your home to the outside. The condenser works by exchanging air, cooling it, and then blowing the cooled air through the central air-conditioning system. The outside condenser unit consists of the fan, outdoor coil, compressor, and electric control box. The fan helps to move heat and air around, while the outdoor coil cools and condenses the refrigerant, and the compressor circulates the refrigerant. Together, these components work together to keep your home cool and comfortable.

Why is my AC unit fan not spinning?

The main reason your AC unit fan isn’t spinning could be a lack of power to the fan or an obstruction. The other potential issues are the fan isn’t getting enough voltage, the fan motor is too hot, something is stuck in the fan blades, or the fan belt needs to be replaced.

Why is my AC unit outside not turning on?

The main reasons your AC unit outside is not turning on could be something that has tripped the circuit breaker, something is blocking the fan’s airflow, or the condensing unit is damaged. Other potential issues could be the thermostat isn’t set correctly or the compressor could be malfunctioning. If you can’t get your outside AC unit fan not running but the inside unit is, contact a professional to take a look.

Why is my outside AC unit fan not running but the inside is?

If your inside unit is running but the outside AC unit fan isn’t running, there could be a few potential causes. To diagnose the problem, first, check the circuit breaker, then inspect the condensing unit for any visible damage, and then check if the fan’s airflow is blocked. Other possible issues are the fan is driven by a belt that needs to be changed, the fan is frozen due to a lack of lubrication, or the fan motor is bad. If you can’t find the issue it’s best to contact a professional who will be able to properly diagnose and repair your AC unit.

Troubleshooting when your outside unit isn’t working

When the AC unit fan isn’t spinning and the outside unit isn’t turning on, you can try a few different steps to troubleshoot the issue. If you can’t get the AC unit fan spinning or the outside unit turning on, contact a professional to come and take a look. With proper repair and ongoing maintenance, your AC unit should be working properly and running smoothly in no time.

1. Check the circuit breaker

The most common reason for a condenser to stop working is something that has tripped the circuit breaker. A circuit breaker is an electrical safety device that shuts off power to a circuit if it detects an overloaded electrical load. This could be due to a bad electrical connection, an overheated motor or a short circuit. To check the circuit breaker, locate it in your home’s circuit breaker box and look for a tripped breaker, which will be in the center position between on and off. Reset the breaker and see if your AC works again.

2. Clear any blockages blocking the fan’s airflow

Another possible problem that is causing your outside unit to not work is that there may be something blocking the fan’s airflow. If it’s clogged with dirt, leaves, dust, or other debris, the cooling effect won’t be efficient and your home won’t be able to cool down properly. You can clear the fan of any blockages if you’re comfortable doing so, or you can contact a professional to take a look. It’s also possible that the fan simply isn’t running because the motor is bad, the fan is driven by a belt that needs to be changed, or the fan is frozen due to a lack of lubrication.

3. Check the condensing unit itself for any visible damage

You’ll also want to check the condensing unit itself for any visible damage. If it is rusted, corroded, or shows any other signs of physical damage, you’ll need to contact a professional. They’ll be able to determine if the condensing unit needs to be replaced or repaired.

4. Check the thermostat

One last item to check if your outside unit isn’t working is the thermostat. You should check if it’s been set to the correct temperature and also make sure it’s set to “cool”. If the AC settings are not right, it won’t turn on. You can also check if the batteries in the thermostat are fresh and replace them if needed.

Everything You Need to Know About AC Freon

Imagine this – it’s the middle of summer in Lafayette. The kids are out playing and the adults are sipping a refreshment by the pool. Everyone is enjoying the bright sunshine and warm weather until your AC starts blowing warm air.

Luckily, a problem like this may be as simple as adding AC freon to your unit. Let’s dive into the specifics about AC freon, to make sure you don’t have to worry about the summer heat.

What is AC Freon & How Does it Work?

AC freon is a type of refrigerant commonly used in air conditioning systems. It is a chemical compound made up of various elements, such as fluorine, chlorine, and carbon. 

Freon helps to cool air by absorbing heat from inside the home, then releasing it outside. This is accomplished through a process called refrigeration, where the heat energy is converted into a much cooler form. The refrigerant then passes through an evaporator coil, which cools the air before being released back into the room. The remaining heat energy is released outside, cooling down the air in your home.

How Often Do I Need to Check or Replace My AC freon?

AC freon is essential for air conditioning systems to operate properly. Without it, the system would not be able to cool the air efficiently. It helps make sure that your system runs smoothly and without any problems.

It is generally recommended that you check your AC freon levels at least once every year. If you notice any signs of a low refrigerant level or if the pressure gauge on your outside unit is low, you may need to replace the freon.

How to Know if You Need AC Freon

If your air conditioning system is running inefficiently or not cooling properly, you may need to add more AC freon. You can check the level of refrigerant in your system by looking at the outside unit. 

Here are a few signs you may have a freon leak:

  • The pressure gauge on the outside unit is low or reads zero. 
  • The air coming out of the vents is not as cold as it should be. 
  • You hear hissing or bubbling noises coming from the outside unit. 
  • There are visible ice crystals forming around the evaporator coil or refrigerant lines.

It’s also important to note that not all air conditioning units use freon. Some newer systems may use a different type of refrigerant, such as R-410A or R-32. It is important to check the label on your unit to make sure you are using the correct type of refrigerant for your system. When it is in doubt, you can call on one of our expert AC technicians to handle it for you.

In fact, adding more AC freon to your air conditioning unit is always best done by an HVAC professional. Our team of HVAC professionals is able to properly measure the amount of refrigerant your system needs and safely add it without causing any damage.
