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.By the way, it is a 15,000 btu ducted unit.Hot in LV.

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

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.

The air discharge is different- center on the Briskair II, side on the Briskair. Dometic does still stock the Briskair just for Newmar people, though they don't have lots of them.

Thanks for the replies. Chris, You nailed it. that is exactly what mine looks like. Hopefully tomorrow we will find someone that knows what you are talking about. I never ceases to amaze me how many service "professionals" have so little clue as to what is going on.

It will not. ONLY Penguins come with the control board, but those are 12 button boards. This link shows the 5 button and the galvanized control kit you need the galvanized box with the control board inside. The 2nd link is the control kit only. Doug

Thanks, I will keep my fingers crossed. It is supposed to be near 100 again on Thursday.

If they got the right one, it will, and they should have it right. On those units the electronics are in the upper unit.

Well, you will have to replace the upper control board with a 5 button control kit. The 5 button will NOT work on the 4 button control kit. Doug

That means you have purchased a tstat AND control module kit. If you only purchased the 5 or 12 button Tstat, it will NOT work with the 4 button control module. If you are replacing just a standard Brisk Air 2, then your original control kit and tstat will work. BUT, If it was me and you were my customer, I would indeed recommend replacing the 4 button system. You are way past the normal life expectancy of a 4 button. The only time a NEW model will not work with the old control system is if it is a Heat Pump. Doug

Why replace the tstat if it is working? Also, WHERE did you find a NEW 4 button? They have not been built in 16 years and have been out of stock for over 10 years. Doug
