Whats the best to clean evaporator and condenser

The cold evaporator will collect condensed moisture and the condensation normaly drains out the condensation drain path.
As the evaporator fins sweat, dust and particles get stuck to the moisture and fins. Dirty evaporator fins hold more moisture than clean fins. As air rushes thru the fins, moisture is blown off.
It is important to maintain clean air filters, and to treat the evaporator with evaporator cleaner as needed. The outdoor condenser also needs free air flow, periodic cleaning.
It is normal for alga to form and clog condensation pans and drains, periodic cleaning is part of their maintenance too.
There are dedicated chemicals for the maintenance of severely contaminated situations, use as directed. I prefer flushing out clean with a garden hose, persistent alga needs chemicals in cake form or spray, use as prescribed by the product.

find an air conditioner service shop in your area as there are non caustic products available to use to clean the fins on the evaporator and condenser
places that sell compressors , driers, evaporators condensers to the air con trade will be the best place to go to
I use a product called viper E+ enzyme power which you spray into the fins of the units and it actively cleans for hours
it is a non rinsing cleaner made by refrigeration technologies part no rt350g

not cheap but very effective

Condenser coil (outdoor unit) plugged. Outdoor fan not coming up to speed. Overcharged with Freon. These are the things to check.

condenser coils - thats what u clean, its behind grill on the top, u will see coils there. Evaporator does not need to be cleaned ever!

To clean the condenser use the flat attachment on your vacuum cleaner and it should be obligate back in there also available from appliance store you get a condenser brush back again we got out always unplug the appliance before working on it

Check and clean the filter if found to be dirty. It is usually behind a decorative panel below the cold air output grates (when the cold air is on the top front).


The filter is behind the large, rectangular, slotted front panel. The evaporator coil is behind the filter. The fan behind the evaporator pulls the room air through the filter and evaporator coil where it is cooled and dehumidified. It is then discharged through the grates on the top of the front.

Direct the airflow from the unit up and away or left / right to prevent the cool air from being drawn in the front of the unit (this is where the thermostat sensor is located). Use the highest fan speed to help force the air away from the intake, too. Inspect the condenser and evaporator coils (condenser is outside and evaporator is directly behind the filter. Clean if dirty or icing over. Be sure to install a filter if none was present. There are products made specifically for cleaning between the fins of the condenser and evaporator coils. Use them only as directed.




If these suggestions do not work, you may have a problem with the thermostat, refrigerant level, condenser or condenser fan.

Good luck!

The AC evaporator/core condensation drain tube is located on the passenger side of the fire-wall towards the bottom of the fire-wall, (it resembles a heater hose that is coming off from the fire-wall and it connects to nothing, and it is just to drain the AC condensation) and it is easily viewed from under the vehicle. Use long pipe cleaners folded in half to clean out the AC drain, and be very careful that the AC evaporator/core, or the heater core is not damaged from using any hard or sharp objects to clean out the AC drain.

The air handler should be pitched enough to to alow the evaporator condensate pan to drain. the best way I have found to keep it and the drain pipe clean is to use a wet/dry vac Some drains have a **** trap to keep some water in the drain pan.

it's in the high pressure liquid line.

A/C Evaporator Core Orifice The A/C evaporator core orifice (19D990) should be replaced whenever the A/C compressor (19703) is replaced for lack of performance (internal damage). The A/C evaporator core orifice, located in the condenser to evaporator tube (19835), cannot be serviced in detail as a component of the line. If replacement is necessary, follow the procedure outlined for Liquid Line Removal and Installation. An orifice tube replacement service kit may be used as an optional service procedure. Refer to Section 12-00 for information regarding the use of an A/C Evaporator Core Orifice Replacement Kit E5VY-19D695-A.

A/C Evaporator Core Orifice Replacement Kit Installation

1. Discharge A/C refrigerant system. Refer to System Discharging and Recovery as outlined.
   

1. Remove condenser to evaporator tube (19835) from vehicle.
   

1. Locate A/C evaporator core orifice (19D990) by three indentations or a circular recess in metal portion of the condenser to evaporator tube.
   
   
   A/C Evaporator Core Orifice Location
   

1. Note angular position of ends of condenser to evaporator tube so that it can be reassembled in correct position.
   

1. Cut a 63.5 mm (2.5 inch) section from condenser to evaporator tube at A/C evaporator core orifice location. Do not cut closer than 25.4 mm (1 inch) from start of a bend in tube.
   
   
   A/C Evaporator Core Orifice Section Removed From the Liquid Line
   

1. Remove contaminants from the two pieces of the condenser to evaporator tube.
   

1. NOTE: The inlet half of the condenser to evaporator tube will be positioned against the A/C evaporator core orifice tabs when correctly assembled.
   
   Lubricate fitting with clean refrigerant oil and assemble orifice tube kit (with A/C evaporator core orifice installed) to condenser to evaporator tube. Make sure flow direction arrow is pointing toward evaporator end of the condenser to evaporator tube, and taper of each compressor ring is toward compression nut.
