How long did it take to install the mod system?Regardless, I'm committed and love the system so far. We did have one day at end of winter here in Charlotte that was very cold and wet (feb-mar). My windows fogged up quite a lot, but I was able to blast them clear with defrost heat from the MoD system (which blows very strong) in about 2 minutes. I'm just sharing my experience so far, not trying to debate anyone's experience or theories. I'll report out on findings this winter when get up in altitude for some winter, snow trips.

Anyone using the ministry defender heat/hvac kit
Looking for feedback on the ministry defender heat/ ac combo unit. Kit is complete and includes all hoses and fittings? Are you happy with the quality and the output of the ac temperature?
I’ve been using a webasto diesel heater these past winters, but may remove that system in favor of this ministry kit. Feedback welcome….:thanks, Jim

Their YouTube Video shows them not using the electric fan. They kept the stock radiator fan.
Has the vendor provided any solutions ?At this exact moment, I’m not impressed with my MoD unit at all.
Just had it vacuumed and recharged.
It takes 10 degrees farenheit off the input/ambient temperature (91 degrees at the footwell becomes 81 degrees at the vent).
I’ve double and triple checked that there is no coolant leaking through the system too.
And now the condenser fan remains on for at least 10 minutes after I shut the truck off.
Not super thrilled with it.
Good update. Enjoy!This morning I removed the heater lines from the unit, and it’s blowing as cold as I would expect now. The poorer performance was definitely related to a faulty one-way valve.
Ambient temp of 71 degrees and the temp at the vent got to 49.6 degrees… so taking about 20 degrees off (which I am happy with).
My observation though is that you have to be travelling at speed to get this temp. If you are just sat idling (with the condenser fan running), it will only take 10ish degrees off ambient.
If it is 90 degrees out I’ll expect 70 degree output at the vent… if it’s 110 degrees out, I’ll take Range Rover Classic😉
I’m happy with it again. I could make the cabin a lot easier for it to cool by tinting the glass and adding some insulation and a headliner… but I’ll leave those to the next owner.

It can make a difference to a pet who is riding shot gun with the top up!!Is there even any point in me looking into AC in the distant future when I have a soft top in Florida???
What was the wiring challenge?I have had mine installed for 8 months now.
support is excellent, Wiring it up was a challenge.
we are driving 30 year old trucks not designed to be comfy. MOD hvac is a great improvement, but it’s
not modern day cold and heat.
I agree with Ozzie’s post.
