If you're handy around the house, you may be tempted to try to fix it yourself. It's important to know what you can and cannot do. If you're not sure what's causing your AC problems, or if you're uncomfortable working with electrical or refrigerant systems, it's best to call a professional HVAC technician.

However, there are some key features to consider to ensure a smooth and successful AC replacement in Hawaiian Gardens, CA. 

• What you can do

1. Change the air filter

One of the easiest and most important things you can do to keep your AC running smoothly is to change the air filter regularly. This should be done at least once every three months, or more often if you have pets or allergies. A dirty filter can reduce the efficiency of your AC and even lead to a breakdown.

2. Clean the outdoor unit

Your AC's outdoor unit can become clogged with dirt, leaves, and other debris. This can reduce the airflow and make your AC work harder than it needs to. To clean the unit, turn off the power to the AC, remove the grille, and use a hose to gently wash away the debris. Be careful not to damage the fins of the unit.

3. Check the thermostat

If your AC isn't working, the problem may be with the thermostat. Check to make sure it's set to "cool" and that the temperature is set lower than the current room temperature. If you have a programmable thermostat, make sure the schedule is set correctly.

4. Inspect the ductwork

If your AC isn't cooling properly, the problem may be with the ductwork. Inspect the ducts for leaks, holes, or other damage. If you find any, you can seal them with duct tape or use a special duct sealing product.

• What you cannot do

1. Add refrigerant

If your AC is low on refrigerant, you may be tempted to add more yourself. However, this is not a DIY job. Refrigerant is a toxic substance that can cause serious harm if not handled properly. In addition, adding too much refrigerant can cause damage to your AC and reduce its efficiency.

2. Replace electrical components

If you're not an electrician, you should not attempt to replace electrical components in your AC. This includes the compressor, fan motor, and capacitor. These components are dangerous to work with and require specialized knowledge and tools.

3. Repair the Compressor

The compressor is the heart of your AC system, and if it fails, your AC won't work. However, repairing or replacing the compressor is not a DIY job. This is a complex task that requires specialized knowledge and tools. In addition, if you attempt to repair the compressor yourself, you may void your AC's warranty.

4. Fix the evaporator coil

The evaporator coil is responsible for cooling the air in your home. If it's damaged, your AC won't work properly. However, fixing the evaporator coil is not a DIY job. This is a complex task that requires specialized knowledge and tools. In addition, if you attempt to fix the evaporator coil yourself, you may void your AC's warranty.
