Question Heat pump:deep cleaning of A frame

This should be generic to most heat pumps. Does anyone have instructions on how to "deep clean" the A frame in the in house portion of a heat pump. My drips during A/C use and I have been told getting all the gunk out of the A frame will resolve this problem. Someone mention an "acid" cleaning but I just need to know what product to use and how to do the job. Thanks.

Stay off the acid....

Use something milder like any household degreaser. The very best way to attack it would be to spray it from underneath, let it set a few minutes and take a wet vac to it. If it's still rather clogged up bring in the water hose with a sprayer and attack it from the top back down through the coil with quick bursts, stopping every little bit to wet vac the water off the floor. Some dirty coils can be saved for a spell, some are too far gone. No dirty coil will ever be 100% again. The next step is to pull the blower assembly and clean it, too.

Hello: cebrun Welcome to the Do It Yourself Web Site.

I also suggest avoiding any acid or acidy chemical for cleaning coils. Any residues left behind will or may cause pitting. Best cleaning agent would be soapy water solution.

The dust is not held onto the coils by oil or grease. All accumulated dust should come off without the use of harsh chemicals. Use a garden sprayer to apply the soapy water solution and rinse throughly. More than one application and rinse might be needed one the coils.

DO NOT spray soapy water solution into blower, onto the blower motor, on or near any electrical parts or componets. Damage and or shorts, etc. will occur. Allow ample time to dry.

Be sure the electrical power is turned off to the entire unit or it is unpluged from the power source before starting the task. Reseal around entire unit when done. Replace air filter and oil motor, if oil caps present and oil fan blower cage bearing, if any oil caps are present.

See if you cant use a shop vac on the in -side or bottom of the coil first when it is dry. There also is whats called a fin comb get one and use it there . Then from the top side there is a nonacid base coil cleaner for there ,wash the coil down from the top side. After this spray down with a 50/50 mix water and clorox. Then wash out or suck out the drain tray. Also make sure the drain trap is clean if you have one there.
