A/C winter preperation

[amannamedtruth]

Yea, I know, some of you will tell me to just to use cold, dry, winter air, but I'd rather keep everything sealed...

A/C units can freeze up below certain temperatures, unless you have a short cycle set up, but even then, you may end up with condenser sludging up, and your unit will still be inefficient.

So here's a couple key things I've done over the past week or so to retrofit my IdealAir 24,000 btu for cool ambient temperatures.

Disclosure, I am not an HVAC tech.

#1: Head pressure control unit; regulates your fan motor to control the temperature, and thus, head pressure. Also prevents freezing up. Slows your fan during low ambient temperatures to help keep things warmer outside. This will also help with overall efficiency.

#2: Crank Case Heater; Basically keeps your condenser warm to keep refrigerant and oil from separating too much, thus allowing your condenser motor to run smooth, especially after starting up after more than a few minutes of being off. You should probably have one of these anyway, just to prolong the life of your condenser.

Please feel free to add, if you feel inclined, especially if you are an HVAC tech.

Hooray for winter!

id get a hepa filter .. and make urself a box and using ducting create a cold air intake.. that is filtered so it will be just as good as the AC sept ur going to save a ton of energy.. u could air cool ur lights and exhaust that seperate as a closed exhuast getting rid of the heat..

honestly i dont understand people that would rather use a air conditioner.. then nice fresh air..

just like i dont understand y people would waste the heat that ur lights put off during the winter to heat ur house. just use a lung room that filters air and freshens it with a ozone and air fresheners.

Maybe some people don't like to waste CO2...or worry about buying a climate controller to run a few more gadgets...

Yes, this is a given...

Like I said, lets keep this to winterizing A/C and not how to eliminate it, for those that would rather use it. Ever wonder why IT people don't use cool winter air to cool their server towers?

Consistent, controlled environments grow the best herb.

I will be using fresh air to cool. I can save the $$ on my PGE. It adds up..Finding the right spot to install the in line Is the hard part. I should have done this when it was nice out. I need to go under the house find the room install a 6" flange..It needs to be in a location that is out of the way in one of the corners preferably. I can always put a 90 on it to change the direction of the air..I do hate cutting holes in my house. What ever I do it has to be something I can undo(repair) as if there was nothing there. The carpet will not be cut. I will just bend that corner and staple it down..


They have heating cables you can use to keep that area warm.. You onlu need to heat it up just above freezing. I would set it to 40f.. Just put this close to the pipes/condesor inside the unit. This will work..
