1. If I use the Electric AC System, does my batteries will run out?

Your truck will never run out of battery due to the A/C system. The A/C system can sensor the voltage of your battery, when the systems sensors that your battery is low (around 11.4V) it will turn off in automatic.

2. If I want the Electric AC System, do I have to get extra batteries?

The A/C works with the primary batteries of the truck (AGM batteries or deep cycle), it doesn’t need a diesel motor to work (as an APU), doesn’t need extra batteries.


3. Does the Electric AC System is connected with the motor or computer of the Truck?

Doesn’t need to be connected to the truck´s computer system, motor system, doesn’t mess with the alternator (we don’t need to replace it for a bigger one), it is totally autonomous and this makes it easier to install, uninstall and move it from one truck to another.


4. How much time does the Equipment can run?  
It runs for 10 hours long every time your batteries are charged. Charging time batteries is around 5 hours.

5. In How much time does my equipment can be install in my truck?
Installation time is around 2.5 hours 


6 .Does my Electric AC System has warranty? 

2-year factory defect warranty.


7 .What kind of Maintenance do I have to do to my AC System?

Maintenance is minimal: with a pressure air gun you have to remove dust from the condenser and evaporator, and clean or wash the evaporator washable filter every month.  Also you have to change the fan condenser (cost of the fan $86.00 USD) and blower (cost of the blower $123.00 USD) every year.
