Questions:
I have never taken apart an ac unit so some of these Questions might silly to ask. But please answer them.
1. I only see two screw, I am sure others are hiding underneath the mask. What side do I need to take it apart? Also silly question, my furnace is gas. Can I not enter Ac unit from the furnace that is located on left side of the ac unit if you can see from my picture above.

Can't see enough to tell you how many screws, or their location.

2. What tune-up does the furnace needs and how often.

Safety check(switches, limits), and combustion check.

3. Do I need to turn off any switches for gas furnace and Ac unit main switches? Example if I am working on ac only do I need to turn off the gas furnace.

Just the service switch for the furnace when you are working on the indoor oil only.

4. Coil once the cover is lifted what I need to spray and what not to spray. Assuming cooper is in side. Picture will help me. Of course I do not want to take the aluminum bag off the cover, right? It will lift with the cover.

The fin area. Really should spray the under side whee the air enters.

5. I bought a small air compressor, spray for coil and the mask stuff already. Anything else I need.

High pressure air blown at an angle, will bend the aluminum fins over, and do more harm then good.

6. If I do not want to create a T on primary drain and just get a switch for secondary drain. But do maintenance once a year or every two year until unit needs to be replace. Will that be ok.

Probably.

7. Of course you mentioned that as power full as a compressor can be. I can blow it form my master bathroom primary drainage pipe end and it will still be on. The dirt will just sit in the ac unit?

Yep, and just flow back down the drain line.

8. When will this unit need to be replace its a 2002 installation.

When either it dies, or you decide you want to upgrade.

9. I need instruction of where do I find wiring for switch and hoe to wire them.

In blower compartment. The yellow ire to the outdoor unit.

10. Any picture or illustration will help.

Pics of plenum from further back.

11. What do local companies do when they come to do tune-up?

Don't know what companies in your area do.

12. Do I need to clean out door ac unit? How? Its loosing paint on top a little, can I use wood paint on it? Going to re paint form external part of my home this summer.
Outdoor coil should be cleaned every year.

air conditioner Primary and secondary drain


Sorry for all the questions. I did some more research and wanted to make sure I learn everything before taking things apart. I only bought the small compressor so I can clean out the drainage at both ends, from inside the box near the coil where the primary drain starts and from my master bathroom where the pvc pipe ends around 7-12 feet long, i think. I got this http://www.homedepot.com/p/HDX-2-Gal...5#.UdXDZ_nbMzs. will this work at 100psi max or do i need to exchange for a better one.



1. which side do I take apart. the cover?

2. what is the third pipe that looks like an "L" shape, whats its purpose?




above pic shows my furence on left size As my coil on right side. where is the blower located and the yellow wires to attach float switch. And how to properly wire them without getting electrocuted. If the wires are inside the mastik coil unit. I rather get it done when I take that apart and re-mastik it.

also HD website only show these float switches, My pan is metal and they look like are ones for PVC pipes.http://www.homedepot.com/webapp/cata...gry=Search+All

if you guys need better pictures please let me know.

Third pipe is the coil's drain pan over flow pipe, that is caped off.

Those are sump pump switches. You need a drain pan float switch.

Blower is in the furnace on its left side.

Don't know which side will give yo best access to coil.

You could get a PVC cutter. Cut the PVC at the half way point between the el and coil, suck out the dirt with a shop vac. And then use a piece of 1" ID vinyl hose to couple the pipe together, along with 2 hose clamps.

Look, if your A/C has been working since 2002 why not just unscrew the fitting under the sink and see if there's a bunch of gunk blocking it there.

Then if is clean it out and see if the primary starts draining again before you start cutting and blowing and ruining your drain system.

Then if it starts working you can relax and really take your time and finish the drain system at your leisure with the right parts and time.
