If your air conditioner isn’t keeping you cool, one of the first things to check is the evaporator. This is a metal plate that sits on top of your condenser and has cooling fins on it. When the AC cycles on and off, it blows warm air over these fins while they’re still cold from having been outside. The cycle repeats itself every minute or two as long as the unit is running, so there’s plenty of opportunity for dirt and dust to collect here! Fortunately cleaning this part is easier than you might think; Also, a properly maintained air conditioning (AC) unit can help you save on energy costs and keep your home comfortable all summer long. However, there are many tips on how to clean ac evaporator, the steps involved in keeping it clean. The following tips will help:

Before you start cleaning the evaporator, make sure to turn off your air conditioner.

It is important to turn off the air conditioner before you start cleaning the evaporator. If you don’t, it will take longer to dry and could short out your system.

Once you have turned off the air conditioner, inspect the evaporator for any visible signs of mold or mildew growth. If there are, use a soft brush or toothbrush and some warm water to scrub away any dead cells. Once they are removed, wipe down with a clean rag until all remains of them are gone from your AC Evaporator surface area.

Turning on an air conditioner without removing any debris from within can damage the condenser coils which leads them being unable to cool properly which could result in higher utility bills or worse case scenario: fire!

A maintenance checklist to follow.

It is important to clean the unit at least once a year. If you do not do this, your AC compressor may fail prematurely.

  • Clean the condenser coils:

You should also make sure to clean the condenser coils on a regular basis. This will ensure that no debris gets into them and clogs them up as well as keep them from rusting over time. You should use a brush that is made for cleaning coils so that you can get in between them without damaging anything else in there (like paint). Most companies recommend using an anti-rust solution before finishing up with water so that no rust can develop on any surfaces exposed during cleaning.*

Check the unit and clean it.

  • Check the filters. They need to be cleaned or replaced regularly to ensure the proper airflow through your system. If you don’t have access to a vacuum cleaner, use a soft brush to remove dust from the surfaces of each filter in addition to vacuuming it with an upholstery attachment.
  • Clean the drain line by removing any debris with a garden hose or cleaning solution and then let it dry completely before reinstalling it back into your unit.
  • Fan motors can become dirty over time which will reduce their lifespan significantly (the same goes for blower wheels). You should inspect these components periodically and replace them when necessary as well as check bearings on motors that are exposed outside of their housings (such as those in window units) because they will wear down quicker than ones that aren’t exposed at all times like those found inside split-systems – if there’s one thing we know about AC repairs: fans are very important!
  • Compressors can become clogged over time due to debris build-up inside them so make sure yours is running smoothly by checking its oil level every two weeks or so – if yours needs replacing, contact us today!

Remove the panels.

  • Unplug the unit before starting. This is important to avoid an electrical shock or damage to your AC unit.
  • Remove the panels, if you have a window AC, it will be easy for you to remove the panels by just lifting them up and pulling outwards. If there are screws holding them on then unscrew them with a screwdriver and remove them carefully so that they don’t fall off into your hands while doing this job!
  • Use a vacuum cleaner (if available) or soft brush/broom to remove debris from inside of these cabinets where dust has accumulated over time. It is very important not only because it looks bad but also because they can cause damage if they fall off while putting back together again in future years! If there are fans inside then make sure not too much water gets near those because electric systems might get wet down there which could cause serious problems later on when trying turning power back on again without damaging anything else around nearby like transformers etcetera… So try dry everything up quickly after cleaning with cloths before going ahead further into next step below:

Use a leaf blower to clean.

If you have a leaf blower, use it to blow out dust and debris from the coils. You will be able to see that the dirt is pushed out of your AC evaporator. The second step is to blow out any additional debris with the leaf blower before beginning a cleaning process.

The third step is to use a leaf blower to clean coils, condenser and drain line of your air conditioner unit by following these simple steps:

  • Shut off power at breaker box or disconnect electrical connections (if possible).
  • Move away from unit and turn on leaf blower high-power setting for several minutes so that air flow directs towards coil fins and fan blades before spraying with water from garden hose as shown in photos above; then turn off power at breaker box or reconnect electrical connections (if possible).

Replace the panel.

You can replace the evaporator panel with a new one, or you can replace it with a panel that is the same as your old one. You could also swap it out for a different color panel.

Replace the drain pan and drain line.

The drain pan and drain line are easy to replace. Check them first to make sure they aren’t damaged and that they aren’t leaking or clogged. If you find any damage, replace the pan or line with a new one from your local hardware store.

If your AC evaporator has an issue with its drain pan, check this area first for problems like water leaks or cracks in the metal that could cause major damage if left unattended for too long!

Cleaning the condensate pump or overflow switch.

The condensate pump, also known as the drain pan, is designed to remove excess water that accumulates in your AC evaporator coil. It pulls hot air over the coil and uses centrifugal force to move this excess water through a discharge hose into a drain pan. Over time, this discharge hose can become clogged with dirt and debris, preventing it from doing its job efficiently. If you find that your AC is not cooling properly or draining correctly when it’s turned off (or not draining at all), then there may be a problem with the condensate pump or overflow switch in your system.

To clean these parts:

  • Remove any hoses connected to your condensate pump assembly (if applicable).
  • Clean out any clogs inside of the discharge hose by blowing compressed air through it or pouring water down until clear again..
  • Replace worn hoses or damaged gaskets with new ones from an appliance store if needed.*If you need assistance installing new hoses back onto existing plumbing connections within our home’s central air conditioning system itself–a task which should only be attempted by experts working under guidance from qualified technicians–please contact us today!

An AC unit is an expensive yet essential appliance in your home, so keep it in great shape for longevity!

Cleaning your AC unit regularly will help keep it in great shape for longevity. You can clean your AC unit yourself, or hire a professional to do it for you. Here are some maintenance tips:

  • Clean the outside of your unit with a soft cloth and warm water, then dry it thoroughly before turning on the system.
  • Vacuum all vents and filters in addition to dusting them with an anti-static duster. This includes everything from air ducts to coils and fans! One way to keep track of these parts is by labeling them before cleaning them so that you know where they go when reassembling your system for maximum efficiency during use later down the line (which leads us nicely into…).


With these cleaning tips, we hope to encourage you to continue using your air conditioner in the summer. If your unit becomes too dirty, it will not be able to work properly and could cause damage if left untreated. We recommend that you follow all of these steps at least once every two months during the warmer months of year so that no one gets hot under the collar!

The information in this article can be used to keep your AC unit running efficiently and at peak performance. By following these tips, you can help ensure that your unit lasts for years to come!
