That skylight will save your light bill. These things are dark inside on a cloudy day.

Planning to shoot an unboxing video and then do a review and installation video. The skid has two 1 ton pioneer heat pumps.

I'm sure in the summer it will hurt my cooling bill, but will help keep warm in the winter!

Cut blocks of foam that fit snugly when you need the insulation, and when you don't you can stow them somewhere.

Do you get that much greenhouse effect during the winter?

Were you asked or did you ask?
i see the line sets. Did they come with the wiring from indoor to outdoor at your specified length and/were you ever asked?
If not then your longest run could be short on wiring and refrigerant?
Just an observation?
I am looking at the same brand multi zone with two 12,000 btu units.?
Have fun

unless your linesets are pre-charged you will likely need to add refrigerant to the 33' unit.. the book will tell you how much refrigerant the units contain (for how much line). mine were only charged for 15' linesets.. and my linesets were not pre-charged so after install, before you open the king valves you need to Vac down the system.. irts especially important with R410A to do a good Vac down.. any air / moisture in a 410A system reduces efficiency rather dramatically. the heat pump units contain an accumulator so a LITTLE over charge wont hurt, but running under-charge will kill efficiency esp on the heating cycle.. not as noticeable on cooling as the way these units are designed less refrigerant is needed for cooling.

my former career was HVAC and systems design so I still keep a good arsenal of tools and did it myself.. in my casse I custom length'd my linesets to fit best since i have the flare tools and all..

those flare fittings.. be sure both sides are nice and clean. i coated each side of my flare with refrigeration oil before i mounted them. my mini splits in my house have been running since 2009, last leak I had was in '10 when I had a pipe crack inside one outdoor unit.

these are fantastic units when you put them together right and will give you lots of trouble-free service..

Might be cheaper to stop in an RV shop after install and pay them to check your work and vacuum and charge them?
Might not be?
I work on the commercial side of a residential service company and I see what they charge??
And I was thinking of getting into mobile Rv repair a while back and found that my local RV dealer/repair center was 15% cheaper for HVAC work.
And it might be my area?

Years ago I got a great deal on a "Dealer Fit" AC option kit for my Landrover Discovery.

I fitted it and the local AC shop charged the system for me. They had already given me a few ounces of the Unicorn Blood lubricant for the o-rings.

The price was very reasonable, but things may have changed and it was in another country.

In Orlando tonight. Picking up my wrecked trailer in the morning. Nervous about whatever the pictures may not have shown and road worthiness.

Well, on the positive side- it's already wrecked.

main thing is whether the shop you go to has the tools for R410A.. a car shop will be used to working on R134a. and mayhe 1234y stuff (newest).. do RV roof top A/C's use 410A? the ones I worked on were 134a (standard dometic).. but maybe some are 410A where a shop would have the tools? R410A is an HFC but runs at MUCH higher pressures than R134a. your regular gauges and hoses for 134a are not fit for 410A pressures. to charge most mini split A/C, you also need a hose adapter for the suction side..
