How to Clean the Indoor AC Unit
Now that you’ve cleaned the outdoor AC unit, it’s time to move on to the indoor unit. Follow these steps to clean your AC unit’s evaporator coil and air filter:
Step 1: Turn off the Power
Before you start cleaning the indoor unit, make sure to turn off the power. You can do this by shutting off the circuit breaker to the AC unit or by unplugging it from the wall.
Step 2: Remove the Air Filter
The air filter is usually located behind the front panel of the indoor unit. Slide the front panel off and remove the air filter. If the filter is dirty, use a vacuum cleaner or a brush to clean it. If it’s damaged, replace it with a new one.
Step 3: Clean the Evaporator Coil
The evaporator coil is the part of the indoor unit that absorbs heat from your home’s air. Over time, it can become covered in dust and debris, which can reduce its efficiency.

Step 4: Clear the Drain Line
The drain line is the pipe that carries condensation away from the indoor unit. Over time, it can become clogged with dirt and debris, which can cause water to back up into your home. To clear the drain line, locate the pipe and use a wet/dry vacuum to suck out any debris. You can also use a mixture of bleach and water to clean the pipe.
Once you’ve cleaned the indoor unit, reattach the front panel and turn the power back on. Don’t forget to change the air filter regularly to keep your AC unit running smoothly!
How to Clean the Blower Fan
The blower fan is responsible for circulating air throughout your home and is an essential part of your AC unit. Over time, dirt and debris can build up on the fan blades, reducing its efficiency and causing it to make strange noises. Follow these steps to clean your blower fan:
- Turn off the power to your AC unit at the breaker box.
- Locate the blower fan, which is typically located inside the air handler cabinet.
- Remove the access panel to gain access to the fan.
- Using a soft-bristled brush or a cloth, gently clean the blades of the fan. Avoid bending the blades, as this can cause balance issues.
- If the blades are extremely dirty, you may need to remove them from the fan motor to clean them properly. Consult your AC unit’s user manual or consider hiring a professional to do this for you.
- Once you have finished cleaning the blades, use a vacuum cleaner with a soft brush attachment to clean the inside of the air handler cabinet.
- If your fan motor requires lubrication, apply a few drops of oil to the oil ports on the motor. Refer to your user manual for specific instructions on how to do this.
- Replace the access panel and turn the power back on at the breaker box.
Cleaning your blower fan should be done at least once a year to maintain its efficiency and prevent any potential issues from arising. If you notice any strange noises or decreased airflow from your AC unit, it may be time to clean the blower fan or have it inspected by a professional.

Common Problems with AC Units and How to Fix Them
While regular cleaning and maintenance can help prevent many problems with AC units, there are still some common issues that can arise. Here are some of the most frequent problems and how to fix them:
Frozen Coils
If your AC unit is not cooling properly, the problem could be frozen coils. This can happen when the airflow is restricted or when the refrigerant levels are low. To fix this problem, turn off the AC unit and let the coils thaw. Once they are thawed, check the air filter and replace it if it is dirty. If the problem persists, you may need to call a professional to check the refrigerant levels.
Refrigerant Leaks
If your AC unit is not cooling properly, it could also be due to a refrigerant leak. This can cause the unit to blow warm air or not cool at all. To fix this problem, you should call a professional to locate and fix the leak. Adding more refrigerant without fixing the leak will only be a temporary solution and can damage the AC unit in the long run.
Faulty Thermostat
If your AC unit is not turning on or off, or if the temperature setting is not accurate, the problem could be a faulty thermostat. To fix this problem, check the thermostat settings and replace the batteries if necessary. If the problem persists, you may need to replace the entire thermostat.
Clogged Drain Line
If you notice water pooling around your indoor AC unit, the problem could be a clogged drain line. To fix this problem, turn off the AC unit and locate the drain line. Use a wet/dry vacuum to remove any debris or buildup in the line. You can also use a mix of warm water and vinegar to clean out the line.
Remember, if you are not comfortable fixing any of these problems yourself, it’s always best to call a professional. Attempting to fix the AC unit yourself can be dangerous and can cause further damage to the unit.
