A/C Problems

Air conditioners come in two by two by many models.. but for this post only one of the "2s" is important,,,, Ducted, and not ducted.

ALL not ducted fit in a 14" square hole.. that is the "Foot print" a 14" square hole. They are ALL the same, a 14" square hole.

Ducted ones the ducting unit may be different. So there you need to be careful, but non ducted, and i suspect that is what you have, all fit the same 14" square hole.. By the way so do Ducted units, but again the ducting unit fits INSIDE the hole, then there is a top part, and a bottom part.

I have a 1999 Newmar fifthwheel and the AC stopped blowing cold air. Had a mobile mechanic come and of course, wanted to replace it. Here in Las Vegas it is 100 degrees, so not much wiggle room. The problem is the unit they brought to install, was a different footprint. It was a Duo-Therm Brisk Air II. After a little research,I found that I need a Brisk Air I. I can not find one of them listed anywhere. Does anyone have any knowledge on this subject? Any thoughts will be appreciated.

Hot in LV.

ALL Brisk Airs have what you call a footprint. In 37 years as a Tech, I have never heard the term "footprint". The Brisk Air 2 is just an updated version on the Brisk Air 1 which was discontinued. What do you mean by Footprint? The Newmar Units are bolted from the TOP with Lag Bolts. That means they may have to drill the 4 mount holes in the Pan of the new Brisk Air 2. Is that what you mean by Footprint? Is this unit a HEAT PUMP also? The control kit is transferred from the old unit to the NEW unit, unless the new unit and OLD is a Heat Pump. If the units are Heat Pumps, you will have to install a new wall tstat and change the upper control board. The reason is, you have a 4 button wall tstat(unless it was changed to a 5 button after 2002). Doug
