Air Conditioner Question

[JusDreaming]

I am trying to figure out if something is wrong with our AC or is it just HOT in Florida. So my question is what should the air coming out of the unit be? I checked ours and it is 70 degrees. It is a "Cruiseair" unit.

A quick rule of thumb for domestic & commercial central air-conditions is that you should have a 15 to 20 degree delta T. The dischage temperature should be 15 - 20 degrees cooler than the return or supply air tempertature.

JusDreaming, I've done a lot of AC aboard in Florida and here are a couple of things that might improve efficiency: 1) Rate of water flow. I personally like the March pumps, but whatever you're using, make sure you're moving enough water. 2) Surface area for heat exchange.....If you have a film on the inside of your metal coils that the water flows through, you may be loosing a lot of heat exchange opportunity. I use a soft rubber snake that I made from a "surfboard leash". This board to ankle leash can be bought at any surf shop & you can ream it through your tubes without damage. 3) Dust/clean the fins on the air side of your heat exchange coils. These fins are increasing the surface area for efficiency and if they are coated with debris it's your loss 4) make sure the thermostat sensor is seated in the influent air draft. good luck, Aythya crew

well I connected the water hose,(shore water), to the AC inlet hose and the temp at the vent went down to suggested temps. So checked the pump and it was not getting enough water to it. So after checking the strainer, I back flushed the thru hull and voila!!! Thanks guys for the help!!!!!!!!
