The force of the vacuum will pull out debris from the coils, making the next few steps easier. An air conditioning unit is a life-saver on hot summer days. When you’re sweating and miserable, the last thing you need is for your AC unit to malfunction. But if you’ve not cleaned it recently, this can easily happen. Coil brushes are made in the right size and with soft enough bristles for evaporator and condenser coil fins.
When to Clean Air Conditioner Coils
The evaporator coils must be fully dry before restarting the air conditioner. Only use cleaning products and a soft cloth if your evaporator coils are very dirty. If your brush and compressed air don’t do the trick, this will remove the stubborn grime from the coils.

A filthy coil can cause your air conditioner to stop working altogether. This can happen when condensation develops on the dust and freezes when the air conditioner runs. Thus, one advantage of keeping coils clean is that your property will cool faster when the coils are clean.
How to Clean AC Coils: Step by Step Guide
Your system is built to operate on cycles according to the thermostat setting. When dirty coils reduce the system's efficiency, it works harder to cool the air, and the cycles become longer. This phenomenon results in a drain on your electricity, resulting in higher costs. Secondly, the evaporator coils in your AC may freeze due to a buildup of dirt and grime.
An A-frame or pyramid-shaped arrangement of copper coils makes up an HVAC evaporator coil for a centralized AC system. If you want to use a DIY solution, water and dish soap is best. Check your manufacturer instructions to make sure that it’s okay to hose down the unit. Because these units live outside, they’re usually waterproof and fine to wash with water. We recommend using a foaming cleanser such as the HVAC Guys Foam Blaster, because the foaming action will lift the dirt from the coils and flush it out. If your house hasn’t been professionally air sealed, then at least some of your cooling issues are actually because of heat gain from air leaks.
What Do I Need to Clean Indoor AC Evaporator Coils?
The hot refrigerant from the evaporator coils passes through the condenser coils, which release the heat into the air outside. Cleaning the evaporator coils is a modified version of cleaning the condenser coils. Since evaporator coils are indoors, it's not possible to hose them down with a garden hose. Instead, use a spray bottle to control the water discharge.
You and your family can rest easy from breathing in all of that trash. Locate the drip opening and wipe it out, being careful not to press any debris down into the hole. Make any adjustments according to a refrigerator thermometer.

The optimum setting for your fridge is between 38 and 42 degrees F; the freezer, between 0 and 10 degrees. Dealers can answer questions, help you find the right products for your home, and repair your system. So, spray the mixture on the coils and let it remain for a few moments to dislodge the grime. Thereafter, reapply as needed after wiping away any unsettled material with a gentle cloth. There are coil cleansers available on the market that do not need to be rinsed such as the Evap foam from Nu-Calgon and the Foam Blaster from HVAC Guys. Don’t be alarmed if you end up using an entire can to clean your coils.
Don’t block them or let crumbs or twist ties get sucked in around the evaporator fan or clog the drain tube. To help save energy, keep your freezer about three-quarters full to retain cold air. But don’t pack it any fuller because the air needs to circulate.
The foaming lifts off all the unreachable dirt and grime embedded in between the fins. Let the cleaner soak for 5 to 10 minutes, according to the instructions on the can. Here, the refrigerator unit in your go-to seasonal appliance absorbs heat to make the air cooler. As air passes over the cool refrigerant, it wicks the heat out in a process that’s essentially the reverse of how your forced air furnace operates. A regularly maintained system will work more effectively and more efficiently than one that is not regularly maintained.
This is done by placing the air nose near the bottom edge of the debris for any remaining stubborn particles. An HVAC unit’s longevity is extended by proper maintenance and regular cleaning, which reduces the chance of constituent damage. HVAC systems that are maintained regularly and undergo annual inspections survive longer.
That’ll show you how good a job you’ve done cleaning your coils. You might find it on the opposite wall from your electric service panel. The evaporator coil is key to removing those nuisances from the air in your home. A dirty coil greatly restricts airflow and causes issues with heat and humidity. Those are the basic steps to give you an idea of whether you want to tackle the job or call a local heating and cooling company to do it.
