So, you pick. More of a push on the AC to save a few bucks on the bill (shortening the life of the unit) or lengthening the life and overall production of your unit while paying a bit more.

You never want to shut off an AC unit in the summer. Even if we get one of those rare 82 degree days, if you decide to shut it down and open your windows for only one day, the moisture you will let in will permeate your walls, carpet, furniture etc, and can take 3-5 days to get back out of your house once you turn your AC back on.

At my first house the AC unit was located on the west side. Totally unshaded and during the afternoon/evening the unit was blistering hot because of the sun.
I built a large three sided well ventilated wooden cover to shade it and it made a difference in how quickly it could cool down the house. When I built this house I designed it so the unit would sit on the east side out of sun during the peak cooling times of the day. |

Another thing it can do is not move enough air across the indoor coil, the evaperator coil, which will make your system not cool properly and can send liquid back to the compressor in your outdoor unit causing it to slug and burn it out prematurely as well.

So, if I turn the breaker off right by the outdoor A/C unit and remove the grate from the top I can blast the coil with water from the inside? Do I need to protect/avoid anything from the water as I do this?

Bugeater, You are fixing to find out that you are going to be a very popular man. Especially in the worst of conditions since that is generally when a capacitor or a compressor or something else fails.
Your friends and family will be calling you and expecting it done for nothing or for a favor later or calling in a favor.

What type of epa card did you get? I have been doing this stuff for 7 years. Been to a lot of classes. And to a lot of seminars by various equipment manufacture.

[QUOTE=Bugeater;7765718]Hey CP peeps, I'm willing to bet some of you have noticed it's freaking hot outside. And since I've spent the last year going to school for HVAC, I thought I'd share some things I've learned about air conditioning systems. If you don't think yours is operating properly, here are some simple things you can check out on your own.
First off, check your outside unit. On it you will find two copper tubes coming from the house and into the unit. Touch them both. QUOTE] Way too hot to go outside. Next. |

On most units the electrical components (contactor, capacitor) are in an isolated area and aren't an issue. You definitely want to avoid hitting those. The compressor and condenser fan motor are both sealed and can withstand some water on them.

Blast might be a strong word here. And be careful going across the "grain" or the coil. You don't want to fold over the fins. The fins are what allow the air to take the temperature off of the refrigerant.

I have a universal license. What's funny is you really don't need to know a whole lot to get it, you just need to be able to memorize a bunch of stuff. I've already run into several people who have them and really have no clue how to properly charge a unit. |

I have found a lot of people that want to use the "flash" technique to charge R-22 systems. I just have to laugh at them knowing they don't know what they are doing and charging someone for them to feel the suction line.
