I use a good medium bristle wire brush with smaller brisstles. gently scrape the surface of the intake side of the coil. clear a section about 6 inches square, then put a drop light on the other side of you can see light clearly through the area you cleaned then you can get by with what we call surface cleaning. continue to clean and vac with shop vac and brush, gently .do not crush or mash fins. dont get cut they are sharp. the only coil cleaner i would use is evap power self rinsing cleaner that has no alkalie or acid to eat up the coil. it disolves the algae on contact and rinses with drain condensate. after a good brush and vac you can gently use a water hose on med spray to flush thriugh the coil .put down towels, use a shop vac and **** out drain with a vac as you do it.unless you are impacted with lots of crud you can usually clean in place. if they are to bad call a servvice company and have them pump it down and pressure wash and sanitize it. with proper filtration a coil should never need cleaning, ever. get a price on an aprilair filter installed if you pay a pro to clean coil. filters last a year and no part to replace. filtration down to 3 microns and filters last a year at 42 bucks a piece. at least consider going to p[leated filters if you dont upgrade to a pro filter system. good luck, wear old clothes ,you are going to get dirty, but that is the joy of home ownership.

Hi. I have an Intertherm air handler and central air unit in my mobile home - Model # (E2EB-012HB) air handler, and a (03QA- 036U- B) A Coil.Simply put, When the cooling unit it running, it cools very...

The A coil (Evaporator) is dirty and needs cleaned by a professional. Dirt has clogged the fins in the coil and is blocking most of the airflow through the coil so the air has to go around the coil picking up the water as it does and sending it everywhere.

Has a service tech remove and clean your coil and reinstall it and your problem will be solved.

My Nordyne air handler has frozen up: Model #B3VM-048 K-B. What can cause this to happen?

Hi, there are a couple of things that will cause your air handler to ice up, some you may be able to take care of your self, and the last you will need to call out a service tech. First of all, you must have a clean filter at all times. 2nd, if the indoor coil has gotten dirty, this will cause decreased air flow across this coil and it will ice up very bad. Cleaning or I should say, getting to this coil to clean can be a job. You will have to bend the sheet metal panels, remove some screws, and work around the freon lines to get back to it enough to remove the sheet of dirt that is covering the coil. It will peel off like a sheet. When they get this way over the years, they will block the return air back through the coil, and it will ice up.Once it is cleaned, you may have to buy a roll of aluminum tape to seal the areas that didn't go back together very good. If your blower motor is not moving air very good, like it is ready to go out, moving slow, or making noise, this will do the same. The last thing that will cause this, is the unit has a small freon leak. If your air handler is gas, you can turn on the heat to melt the ice off faster, if not, turn just the fan on to melt the ice away. Once its gone and you have good air flow, turn the a/c back on and go to the outdoor unit. Place your hand above the fan guard to see if the air is good and warm to hot. Find the large copper line below and grab hold to make sure it is good and cold and is starting to condensate. The smaller line, discharge should be good and warm to hot. This will tell you the freon level is real close to being full, so your problem will more then likely be a dirty, plugged indoor coil. More then likely, this is your problem and would be something you could do your self to save you $$$$. I hope I have helped you on this and given you some direction to go on. I have done this for many years, and know the signs very well. Please don't forget to rate me as I know you will be kind. Please keep me posted on the outcome.

I need piture of my a/c coil to find access panal location to clean evap coil.

It really depends on what system you have, i.e. model number and manufacturer. Most of the time though, you will have the furnace sitting on top of the coil, or the coil sitting on top of the furnace, depending on if you have an upflow or downflow system. Sometimes you will have a horizontal unit that lays on it's side, either way, the coil is the smaller box that is separated from the furnace and has copper running into it. If you have a air handler, then the coil and furnace are built inside the same cabinet. On pretty much all these systems, after you take off the front panels, you will either see the coil, (upflow, downflow, horizontal), or see the panels that cover the coil, (air handler). Cleaning them can be tricky sometimes, and if you have a downflow, you will be able to clean the top of the coil, unfortunately on a upflow, you have to remove a piece of metal that holds the coil together to access underneath it. The best way to clean these for a d.i.y., is a small brass or metal brush, brushing with the fins on the coil and not side to side. Make sure the system is off, otherwise you will get a face full of nasty stuff. On another note, if you happen to be talking about cleaning the coils on the outside unit, you don't have to remove anything, just get a water hose with a sprayer and start at the top of the unit and work your way down, being careful not to use to much pressure that you could damage the fins. People don't realize how much money and problems they could save by doing this. Considering I don't have a lot of information on your equipment, I hope I pointed you in the right direction. Good luck!

My split system gets cold for 1/2 hour then blows hot air, and then it will only blow hot air

1. Check to make sure everything in the condensing unit (outside unit) is running....compressor, fan motor. If you do not have electrical experience, contact a qualified service technician.
2. Check to see if the condensing coil is clean. In many cases this can be cleaned using a garden hose.
3. Check to see if there is any ice or visibly frozen areas. If so, ensure your air filter and your evaporator coil (coil in the air handler) are clean. Ensure your return grille and supply vents are open and not blocked.

Hope this helps. Good Luck! :-)

Air Conditioner (RUUD model: UBHC-14J06NFD) is leaking water from bottom. It is causing a major puddle in Air Intake area.

The condensate drain line/pan is clogged causing the condensation to overflow the pan.

The easy way to fix that is attatch a powerfull wet/dry shop vac to the end of the drain line and such out whatever is causiing the clog. Also take off the panel to the evaporator coil and clean out the pan with the shop vac.

To double check that the clog has been removed, pour a gallon or two of water into the pan and ensure that it is draining properly.
