Dry off with a clean cloth or paper towel. Spray rinse water from the inside outward, clearing away any remaining residue. After the coil cleaner has dripped off the coils, examine the coil surfaces for any areas that may need another application, and repeat this step as necessary. Let the Simple Green sit 10-15 minutes to penetrate heavier soils, and then hose it down again. Cover the condenser coils entirely with the cleaner. Spray the coils down with Simple Green All-Purpose Cleaner.Use a hose to spray out your AC unit, without spraying the disconnect or the electrical components inside the access panel. This helps prevent corrosion and increases airflow. Remove any broken aluminum fins (aluminum fins improve heat transfer) as well as leaves, dirt or dead insects that have gotten into the unit. If you can't proceed without doing this, contact a professional. If your air conditioner's fan assembly is at the top of the unit, be careful not to stretch or damage any wires. Remove the bolts that are attaching the lid to the rest of the condenser, avoiding the bolts that hold the fan to the lid. Turn off the AC at the thermostat and shut off power to the condensing unit.If your AC unit is still under warranty, check the warranty document to make sure self-cleaning doesn't void the warranty. These steps can also be used to clean compressor coils in the outside cabinet of your AC. Regular, bi-monthly coil cleaning with Simple Green All-Purpose Cleaner during warmer months will keep your AC unit in great working order for years to come. Knowing how to clean AC coils is a money-saving DIY skill, an easy way to maintain efficiency and save on energy costs. This can lead to service calls, component replacement, and the potential need to replace the entire system. Less efficiency means higher energy costs, and increased risk of system breakdowns resulting from overworked components. This buildup can force the fans and compressors to work harder, increasing the temperature of the unit and reducing cooling efficiency. These coils tend to be made of copper, and are generally surrounded by a set of aluminum fins for helping to improve heat transfer.Īir conditioner condenser coils capture heat from the air inside your home, and tend to collect dirt and debris easily when in regular use. The condenser coil is located on outdoor units (thus making it more susceptible to accumulating dirt), and is intended to release excess heat to the outside. The evaporator coil absorbs heat and humidity from your home, and is located on the interior portion of the appliance. There are two types of coils involved in the operation of your air conditioning system: evaporator and condenser coils, each serving a different function. Like any machine, basic cleaning and air conditioner maintenance is necessary for appliance longevity. But it's definitely not cool when the air conditioner stops working unexpectedly, leaving the entire household in a sweltering scenario. As air passes through these vents, it drops the temperature of the air before it blows out into the vehicle to cool the cabin.For comfort creatures, warmer weather and air conditioning have gone hand in hand since Willis Carrier invented the modern air conditioner in 1902. A blow motor pushes air from the cabin, or from outside, through vents in the evaporator core. The cold freon then chills the evaporator core as it circulates through. As freon is passing through the expansion valve or orifice tube, this is where the freon pressure and temperature drops right before going through the evaporator core. It will then pass through the expansion valve or orifice tube. The freon will pass through the receiver/dryer or accumulator where contaminants and moisture are removed. It loses heat as it flows through the condenser. When the compressor is turned on, it begins to compress the system’s refrigerant (freon), raising its temperature. A/C in vehicles works by removing heat and humidity from inside your car. A good A/C system is life saver in the sweltering months of summer.
