Air Conditioning works by interchanging heat from inside a building to the outside air. To do this a good deal of very basic refrigeration principles need to take place. One of the most critical pieces that make this take place is the condenser coil. This is commonly the aluminum coil the surrounds the air conditioning compressor.
What happens inside this outdoor unit is a very basic state alter of the refrigerant inside the air conditioning unit. The refrigerant that changes from a liquid to a gas inside the indoor coil moves to the outside where the compressor compresses the gas beneath high pressure. When this happens the gas likewise becomes very hot. The hot gas then leaves the compressor to commence traveling through the galore feet of tubing in the condenser coil. As the gas cools it changes back to a liquid form going back indoors to start out the cycle all over again.
Big difficultnesses begin when the condenser coil becomes so blocked up with dirt that the hot gas in the condenser coil does not cool sufficient to modify the hot gas back to a liquid form. If this happens the cooling routine does not take place and then air conditioner runs but is not cooling. The compressor starts to get very hot and the extreme result will be the death of a compressor. For these reasons the condenser coil must be held clean and free of debris at all times when the air conditioner is running. Cleaning the coil is a reasonably simple process, Here are a few guidelines to follow when doing this.
To clean the coil a few simple tools are needed. A garden hose with a nozzle, wrenches to remove the condenser fan, a garden sprayer for applying the cleaning solution. The firstborn thing is to disconnect the power to the outdoor unit. There must be a disconnect switch of a heap of type near the condenser. Then remove the fan from the condenser unit. Usually this will be the top of the unit. The fan may normally be laid apart conservatively without disconnecting the wires to the motor. Carefully wet down the coil with the garden hose. If you have very high pressure water where you live be careful that the water pressure does not bend over the fins on the coil. These are very thin and fragile. If they get bent over the air will not be capable to freely flow through them. Using the cleaning solution from the garden sprayer, coat he inside and the outside of the coil. Let the solution work on the dirt build up before washing it off. If you use a foaming type coil cleaner then let the foam cook the dirt out of the coil. Then use the garden hose to wash the dirt out of the coil. I oftentimes work from the inside spraying out through the coil. This is the reverse of the ordinary air flow and it washes the dirt out easier. Rinse the coil with water till it is clean with no more dirt or cleaner coming out. Replace the fan and commence the unit back up.
The cleaning solution for the condenser coil may be any good household cleaner. Many automotive type radiator cleaners will work well. For very dirty condensers it would be good to buy a foaming coil cleaner made quintessentially for cleaning condenser coils. A local plumbing and heating supply house will have to stock coil cleaning solutions. Most of these solutions are very strong chemicals. Be sure to wear gloves and eye shelter when working with them.
By keeping your air conditioning condenser coil clean, you will aid to have your air conditioner running at the best efficacy possible. A clean condenser coil is one of the easiest ways to save electric while running your central air conditioning system. A clean coil will concede your compressor to run cooler and help it to last longer. Your condenser coil will have to be exhaustively cleaned at least once a year. If in you live in very dirty areas like along a dirt road you may need to clean the condenser coil more often. Also do not do things that would clog up the coil. Blowing grass clippings into the condenser coil is one mutual thing that happens. Keep shrubbery from growing into and around the condenser coil. This stops the air flow to the coil. Large flowers planted too close to the coil may do the same thing.
As you may see there are galore things that may cause your air conditioner to work harder and cost you more money. By taking a the time to look over things and give it a cleaning you may save a lot of money.

What a deal
I spent quite a bit of time researching A/C before purchasing. We live in Oregon and it doesn’t get too hot but there’s a month or two in the summer where the heat and humidity get oppressive in the house. I wanted an inexpensive, small, window A/C to increase the comfort. I wanted something small enough that I can store it the other 10 months.
So, after much research I ordered this model. I was going to get the 6K BTU model with the electronic controls but I figured I would get something super cheap and if it didn’t work I could use it as a single room cooler. Shipped free which makes this a pretty good deal. Arrived in about a week.
Installation was easy, following the instructions in the manual. I did have to install and remove the A/C about 3 times to get all the sealing right. In the box there’s a lot of different thicknesses of foam and foam tape. There is no specific instructions about what to do with this, except the stuff for the top gap of the upper sash. So, I experimented with various combos to get a good seal. We have recent vinyl windows with screens but no storms so the unit basically dropped right in. However, there are some gaps around the bottom in this configuration. I stuffed these with the thickest foam that came with the unit. This did the trick but didn’t look too great. Luckly I ordered extra foam tape as another reviewer recommended, and I used small pieces of that to caulk around it inside and outside, leaving the big foam inside. It actually looks pretty neat and professional. $4 well spent 😉
Anyway, the unit is installed in our main living room. We are in a 1940’s box bungalow so this room is about half of the width and length of the house. The bedrooms and kitchen connect to it. With it on HI cool/Max(7) the entire house has been very cold and huge amounts of water have been pulled out. We will see how it performs in the upcoming week of 95+ temps. We keep a few $10 box fans around to circulate air so I can move the cold air around.
One thing is that I have heard mentioned on a few other models is that the fan catches water in the pan and spits it around. This is a feature and not a bug ;). The unit is designed to pitch backward slightly when properly mounted. Moisture removed from the room collects at the bottom. The fan blade is coated in rubber and it’s designed to suck water up and spray it on the evaporator coils. This facilitates some precooling of the outside air. It drastically increases efficiency. I would not drill drain holes, as other people have mentioned.
$100, and my house is cold AND quiet. You can’t say much more. If it’s not enough for the hottest day I might get one more and move them to the bedrooms. It’s very quiet on low but I like white noise.. I hope it lasts, even if it doesn’t I’d gladly pay another $100 in 2 years.

Rises Above Expactations
By A. Mast
I got it hoping it would keep my apartment cool-ER. I expected it to keep it comfortable, not cold. I also had a bit of a problem with size. The only window that opens in my house is a vertical sliding window, which Air Conditioners I can afford, aren’t made for.
Once I received it, I started to assemble and install. Originally I was going to leave the extensions off, since my window was only 18 inches wide, but after I got it and thought about it more, I realized they could still help keep it supported. So I put them on. They are about an inch inside the window, to help it from falling out. Also, I originally hoped to buy some wood and put that above it, but once I saw how sturdy it was with just the extensions, I put cardboard above it and plastic taped around the edges with duct tape. Very red neck, I know. It’s sealed with the help of some other bits that came with it to help seal it.
I installed it a little over 12 hours ago and my home is cold. I live in a house above a garage. Just a large living room, average bathroom and small bedroom. It’s 621 SQ Feet.(assuming I did the math correctly. 23 x 27 feet.) This is total, but there are 3 separate rooms here. (Also, I have a low ceiling, only 6.5 Feet.) I placed it in my only opening window in the living room and it keeps the bathroom cold which is closest, and my bedroom pretty cold too, which is farthest. A lot larger than advertised for. I didn’t care, I needed a little cooler than I had. Before, it was hotter inside than it was outside. I have it on high, but will consider turning it down, which I never thought I would do. I like the cold. It’s THAT cold.
For $110, I got an amazing air conditioner that perform WAY better than expected/advertised and it got here exceptionally fast too. It arrived 4 days after I ordered it with standard shipping and handling. I am a very happy costumer.

Better than expected!
By Cassie Monteverde
I bought this a/c mainly because of the price. It has completely exceeded my expectations. It is cooling three rooms in the downstairs of our house (about 600 sq ft). And I have yet to change it over to “high cool”. It’s also quieter than I expected. Well worth it’s low price!
