I have the same problem. You turn it on and the air speed is very low. Increasing the fan speed on the remote doesn't have any effect except when it's on boost, in which case it blasts out. Either too much or too little. Is it a remote problem?

I dont have a solution, but I have a similar problem with a Bonaire evap rooftop cooler which only started after a tech came to look at the unit when it stopped operating properly last summer. He said it uses less water now, but the issue is that it doesnt cool any where near as effectively with the fan speed so low. I am located in Melb Australia, and wonder if you are in the same area. I am going to call service AGAIN & get the minimum fan speed returned to what it was previously. I wonder if my original unit is too small for the house - but nevertheless, it used to work beautifully and now is a very poor example of evap cooling. The service guy said the base fan speed could be altered from the controller, but we dont know how to get into the setup menu.

High low fan motor

Your main concern is the temperature difference across the indoor coil for both heating and cooling. When you turn your thermostat from auto to on, you are on high speed.

If you have long duct runs and little return air registers then high speed
would help cool the house better. However in the heating mode, you
could lose up to 10degrees by having the high speed setting.

What they installed is sized for your house and the speeds should not have to be changed unless the ductwork is not sized right for the house.
Cooling should be High-Black wire.
Heating should be Low-Red Wire.

400cfm equals a ton of cooling= 1200 sq. foot, For cooling you need
High speed. For heating it is whatever the temperature rise across the
coil is, which is located on the furnace/air handler.

The air conditioner use to drip water - it no longer does drip water and continues to freeze over. what could be wrong

It could either be low on refrigerant, a possible dirty coil, or an air flow problem. Rare cases I've seen dirty condensers cause freeze ups.

Fan is not blowing air at its full speed

Check filer. Possible stopped up evap coil. You possibly clean this yourself. Use a stool bruch to clean coils. Does not bend fins. If this does not work call service tech to chemically clean coil.

The indoor blower motor is sometimes a 3 speed motor.The heat usually works on low or medium speed.But the a/c is usually on high speed,this gives greater air flow across the evaporator coil to give you better cooling,also better air flow at ducts.These speeds are usually wired through a relay in the inside unit (air handler).They can be changed.If you go to thermostat and put the fan switch to "on" the blower should operate on "high" speed.With the fan switch set to "auto"the operation will determine the fan speed.Hope this helps.

Air in my condo in not evenly disributed

I would look at having the ducts checked. Alot of them are "Flex" ducts and they collapse over time. Look for poor installation too. Sagging, hard bends and such. There could be the possibility that a duct may have come loose and some or none of the air is making it to the desired space.
I would also look at installing damper doors in the ducts. This allows for you to restrict air flow to one area which would help force are to the desired area.
I have heard of people installing in-line booster fans but I've never heard of anyone saying they work. Don't reccommend that.
Speeding up the fan will change the temp of the air to the space. Don't reccommend that either unless it has been installed at the wrong speed from day one. Outside shot but worth checking.

Good Luck and let me know how it works out.

My cooler is blowing very slow can hardly feel the air

it could be any of three things.

1. its a variable speed motor and will not blow hard unless you have an extreme cooling need (5 degrees or more away from set point)

2. You have collapsed duct work.

3. Dirty evaporator coil, or filters preventing proper air flow

Vulcan-Bonaire : summer breeze

This unit is a cooling unit only. I don't know what switch you are looking at but I don't think it's for the evap. cooler(swamp cooler). I am in the Phoenix, Arizona area and it's very common to have a evap. cooler and a seperate heat/cool system as on the hottest days the evap. cooler doesn't cool enough. I hope this helps. Please give me a positive rating. Thank you.
