I have a central A/C unit that needs cleaning (not the duct work). Can this be done by a homeowner or is this really a job for a pro A/C service? I'm really tired of calling places that provide sub-standard service and in the end I end up doing things myself.
I have a 3 ton American Standard.
Hello TC,
I have a centra A/C also and I have cleaned my own all the time. We live near poplar trees and every year they throw fuzz that collects around the cooling fins. I take my power vacum to it every year. Before I begin I flipp off the breaker that feeds it. I have a 3 ton Carrier unit.. Jimi
You can do considerable damage if you are not careful & don't know what can happen First, always cut all power off to the unit.
Never use detergents on coils & fins as there are oils etc., that will leave an insulating film on them. We use special coil cleaners, and some of those are powerful & dangerous to use.
Keep the water stream straight with the fins or it might bend them.
My advice: Call a HVAC contractor to service the entire system. - udarrell
You should be able to clean it yourself. That and the inside of the air handler too.
Sure. I remove the top fan assembly and use a pressure washer to blow the mung out of the fins.
Now, my fins don't bend. Be careful.
DON"T use a power washer.
This is me, I plan on cleaning my own this year too. I figure a good foaming cleaner will get into the tiny fins. Then I'll hose it down. Remembering to always to follow manufactures instructions.

Sounds like you already made your own decision. Have at it!
Just remebmer that cleaning is only one of the many things a HVAC guy (should) do during the spring clean and check.
