Question:
I have seen people put a fan in the window pointing towards the outside with the idea it pulls the hot air out.

Quite frankly if you try this you will get minimal results.
You would be better off opening all the windows and doors in the house and blowing the fan onto you.
Buy an air conditioner if you really want some relief. It is better to be able to cool down 1 room and be comfortable than playing with fans and windows etc.

Question:
OK…..we live in AZ and it has been about 112-114 for the past week so the a/c has been running a lot to keep the house at 80. On Friday, I was sitting on the couch watching a movie with the kids and it was a comfortable 80 degrees in the house. By the time the movie was over it was up to 86 degrees. My husband looked at the a/c and said it was frozen so we waited for it to defrost and started the a/c again last night and it got down to 85 degrees and now this morning it’s back up to 87 and the coils are frozen again. Any ideas/advice/suggestions to prevent this from happening?

Some of the time it lightly blows cold air (but not enough to cool it down any in the house) and others times no air at all.

One of two reasons why this is probably happening.
First, the airflow across the indoor coil is low. Due to either the filter or coil being blocked, cleaning these will fix that problem. Or the indoor fan or motor is not working properly.
Secondly, you may have a freon leak in the machine. If so then there is nothing you can do to fix it, you will need specialist help.
As suggested above, in some machines, mainly the window type, if they are run continuously over extended periods of time (I mean hours and hours) without cycling off then you may get ice forming on the indoor coil. This is also an indication that the machine is undersized and overworked.
Hope this helps.

Question: Can you duct a standard swamp cooler into an existing homes ductwork?

Reply: Cannot use a central refrigerated air conditioning system ductwork with an evaporative sytems ductwork for a couple of reasons.
1/ The evap (swamp cooler) ducting has a larger circumference as it needs much higher airflows to give the evaporative effect which also usually serves many rooms in the home all at once.
2/ Zoning of a refrigerated system (motorized dampers) are not suitable equipment for evap systems.

Replace the ductwork. And do it properly, get the sizing of the duct determined correctly for the length of the duct runs to the rooms. Balancing of the airflow is important or the outlet closest to the evap cooler will blow off your toupee

Question:

How can I ensure that the entire house gets cooled down and not just a few rooms?
I live in Florida, so central AC is a must! My home is approximately 1300 square feet.
I have central air conditioning but the two farthest rooms in the house are usually warm while the rest of the house is cool. What can I do to ensure that all rooms are cooled evenly? Sounds like your system is a free flow supplying air to all rooms at once.

To fix this a technician would have to go into your ceiling and adjust fixed dampers in the ductwork. By getting the correct airflow balance the air should be able to reach the extremity of those rooms.
If the air is still not able to reach rooms you may have a system that does not have enough capacity to adequately supply those rooms. Believe it or not it is a tricky job to balance the air correctly requiring specialist measuring equipment.
Another consideration is the thermostatic control. It is nearly impossible to cool extremity rooms if these have a high heat load in comparison to the rest of the home, the thermostat cannot know what the temperature is in those rooms and even if it did the system would then freeze the rest of the home in a vain attempt to cool the extremity rooms.
Not as easy as it first sounds is it?
Best to get the experts in to have a look. And be selective as to who you choose, this type of job requires high technical experience from a reputable company…don’t scrimp out trying to save a few dollars.
Good Luck
