Recommendations for new AC

[Chief_Bob]

I have a 14 year old Duo-Therm AC, 15K, ducted, that is getting tired. I had the sealed system tapped and filled to specs but it still doesn't cool as well as it once did.

I want to replace it with another 15K unit and I solicit your recommendations or "stay away from" advice. Thanks

You should run all AC's on high speed fan. Low speed fan will cause them to ice up. Low speed is for heating/furnace operation only.

Lol...if you are having icing issues, yes, running on high will help.

Maybe you don't have auto, but the reason for the auto setting, is to let it decide, it will go to high speed fan when it needs to, if not it stays on low. It may start out on high, when set to auto, if set temp is 6 degrees lower than actual inside temp. Mine catches up fairly fast, and then pauses, sets itself on low speed.

If you have auto setting, you can do yourself a favor, by reading your manual, to better understand.

One last tip...with fan on auto, while using the furnace, the AC fan does not run, only the furnace fan runs.

I've been following this as we are wanting to replace our AC as well. Current unit is a ducted Duo Therm mod: 57915.541.

Looks like the Brisk Air II would fit, and PPL.com has the unit on sale for $466.00 unit 6/8/18. But since I know nothing about this kind of stuff I do have a couple of questions.


1. Assuming that this will work as a replacement, do I need to purchase the inside air distribution box, or does it come with the unit?


2. Will my current thermostat work or would it need to be replaced?

although the ceiling cover panel is different.

Try also http://manuals.dometic.com/download.php?file=1973. It cross references to SK 9105304464. This was a match to the features of my unit.

Good luck.

I’ll send you the link when I get home but I googled brisk air installation instructions

Bob -- can you tell me where you found the directions?
I have a Brisk Air 2 13.5 sitting in its box (since February) and I am hoping to install it some time in June.

The compressor noise is barely audible. The blower on high is kind of loud but it blows a lot harder than the old unit. Not so loud to be an issue. Once it cools down I'll change it to low speed.

Lots of difference in location. Yes, in extreme heat/high humidity, it is good to keep air moving. In some cases, running fan on high will prevent freeze ups. In my area, Iv'e never had a freeze up, or had a time when my 15K Dometic would not easily keep up with cooling.

I had to use the new LCD thermostat but I prefer to have the fan run all the time. I think it helps to circulate air all the time, kind of like a ceiling fan.

I have had excellent luck with my Atwood Air Command 15,000btu unit that was purchased and installed a couple of years ago. Cools and heats very well and is quite a bit quieter than the Dometic Duo Therm unit that finally gave up the ghost after about 12 years.

My experience with the Atwood heat pump has been dismal .....It only runs for 2 minutes then shuts off and Atwood claims it is designed to work that way with the out side temps in the 50's the pump will not raise the temp inside to 70 degrees because it will not run long enough....I regret ever buying it....

I don’t use auto. It shuts the fan off.

I want moving air over the coils to help dry them to help prevent mildew so leave it on low.

[MFL]

Good to hear it's not too loud. Doesn't your new one have the auto fan setting? Mine comes on high, if setting is about 6 degrees lower than ambient temp, and changes to low when approaching set temp.

Maybe you'd have to change the thermostat to newer style with auto setting on fan.

Thanks. I ended up getting the Brisk Air II. I checked the box and the ceiling panel and no installation instructions. I'm about to search the web for them.

Our Rear/Main ducted Brisk Air is quieter than the OEM AC. We added a Mach low profile direct vent to the Bedroom and its VERY loud. Wish I had a Brisk Air there too. Both of my ACs were "retrofitted/installed" by myself in June 2013.
