Your air conditioner may not give cool air as it should, and it happens if you missed a spring checkup. Accumulation of dirt and debris, low coolant level, a dirty fan filter will reduce your AC condenser’s performance and wear it out more easily. You can easily do most of the AC cleaning activities and save extra dollars. But keep in mind to ask a pro to check the coolant level of your AC. In this article, I will tell you how to clean the air conditioner condenser. All the steps are easy and straightforward, and will only take a few hours.
Cleaning Your Air Conditioner Condenser
Cleaning the AC condenser is easy, and here are the steps on how to clean the air conditioner condenser properly.
- Shut Off The Power. Because of the risks of working with the air-conditioner’s electricity, it is important to switch off the power to the machine entirely. Look for an external shut-off box near the machine on the exterior condenser/compressor. You should switch the electricity off at the breaker box indoors too.
- Remove The Debris. You can remove the exterior fan cage of the condenser/compressor. Adjust the fasteners using a screwdriver or wrench and raise the frame or fan grill out from the machine’s top. It’s best to clean the dust and other particles from the interior by hand, or with a wet/dry cleaner.
- Clean and Straighten The Fins. To clear all exterior dirt, remove the protective covers, and use the brush attachment on a strong shop vacuum. Spray through the fins to eliminate any dirt or debris from within them, using a gentle flow from a garden hose. Do not use a power washer, as it can hurt the fins. You can use a common fin washing spray if the fins are especially dirty. Because any change in airflow through the fins will reduce performance, use a butter knife or widely viable fin-straightening tool to safely straighten bent fins.
- Clean The Area Around The Unit. When the cleaning is complete, replace the fan cage. Brush the dirt and debris outside the condenser and cut down branches and foliage at least 2 feet in all directions to increase airflow around the machine. When the condenser is not in use during winter months, it’s essential to cover the top of the machine with a sheet of wood or plastic to avoid debris coming in. Don’t fully cover the sides of the system because moisture will build up inside and cause corrosion. A fully covered device often allows vermin to make nests inside. When the device is running, remove any cover.
- Clean The Evaporator Coil. Now, it is time to step inside. Locate the evaporator coil door on the internal blower/furnace unit. You may need to remove any foil duct tape and a couple of screws or bolts. Use a soft brush to dust off the coil, then spray the cylinder with a no-rinse coil cleaner, which is commercially accessible. The spray fumes up and then drips into the drain pan. Flush the drain pan with soap, warm water, and some bleach. Then pour down to the drain a cup of 50% bleach/ water. Position a widely viable drain pan sheet into the pan to keep the drain clean for the longer term. That will prevent future growth of algae.
- Clean The Plugged Evaporator Drain. Algae and mold will build up over time and possibly block the drain, so it would need to be unplugged if the drain is either not running or running very slowly. A damaged drain can cause flooding into the floor or cause the device to stop cooling. Next, locate the line of the drain where the cage of the evaporator coil exits. Typically the discharge is a one-inch PVC and continues to the edge where it drains. Avoid destroying the filter by safely removing the paper filter from the wet/dry cleaner. Keep the wet/dry vacuum hose right to the end of the piping system. You can either use duct tape or keep a rag around the gap. Switch the machine on for 2-3 minutes and then shut it off. It will remove the drain of any biological matter.
- Clean The Blower Filter. The filter should be adjusted at least twice a year in your HVAC system-once just before the warming season starts and just before the cold months begins. Find the filter housing on the furnace / AC within the device where the huge fresh air return duct enters. You will need a screwdriver to twist the latch into the filter enclosure to open the lock. Remove the existing filter and add the new filter, comparing the arrows on the filter’s airflow path to the device’s markers. Lock the door and latch it.
What Is AC Condenser
Knowing what an AC condenser is will give you some ideas on how to clean the air conditioner condenser.
An AC condenser comes with a compressor, cooling fins, and a fan. The fan draws air through the wings and absorbs a unique refrigerant; then, the compressor pushes through a copper tube into the house to the evaporator. The coolant chills the transformer’s fins and tubes. The warm air by the blower runs through the exhaust system and release through ducts.
The refrigerant dehumidifies the air as it starts to cool, and the accumulated condensation flows through a tube down into a floor drain. Whether you have a boiler, a heat pump, or the blower unit, the ducting device differs considerably. It may be in the cellar, garage, boiler room, or attic.
While these measures will help keep your AC system in top condition, be mindful that there are services that only a qualified HVAC technician can perform. This simple tutorial on how to clean air conditioner condenser is only a guide to cleaning your AC unit. Know more about cleaning appliances.
