Fuel Control
Idle reduction turns overnight rest into controlled electrical usage instead of main-engine runtime.
Phoenix's Preferred EXOair Electronic APU Installer
Electronic APU installs for Class 8 sleeper cabs and long-haul fleets that are done wasting money on idle hours. We install for uptime, comfort, and practical ROI across Phoenix Metro.

What an Electronic APU Does
An electronic APU (eAPU) gives parked sleeper trucks climate control and accessory power without running the main diesel engine through rest periods. For long-haul operations, that means fewer idle hours, less fuel burn, and better driver comfort at night.
EXOair systems are marketed as battery-based cab comfort solutions with battery protection logic and startup safeguards. For fleets, the key is practical usage: less idle dependency, clearer fuel visibility, and easier planning for anti-idle routes.
Typical eAPU outcomes
- Lower overnight idling and avoidable fuel spend
- Reduced main-engine idle wear and maintenance pressure
- Improved driver cab comfort during mandated rest
- Stronger anti-idle compliance posture for CA/metro routes
Why Owner-Operators Choose EXOair
Driver Comfort
Cab cooling and accessory power on parked breaks support retention and better rest quality.
No-Shop Downtime
Install planning is built around fleet operations so trucks get upgraded and return to route quickly.
Fleet ROI (real numbers)
Idle-cost math should be simple and transparent. Start with this framework:
Annual idle fuel cost = diesel price per gallon × gallons burned per idle hour × idle hours per truck per year × number of trucks
| Scenario | Assumptions | Annual fuel burn cost |
|---|---|---|
| Single truck | $4.00/gal × 0.8 gal/hr × 1,500 idle hrs | $4,800/year |
| 10-truck fleet | $4.00/gal × 0.8 gal/hr × 1,500 idle hrs × 10 | $48,000/year |
| High-idle operation | $4.50/gal × 0.9 gal/hr × 1,800 idle hrs | $7,290 per truck/year |
Fuel is only part of the picture. When fleets also account for idle-hour engine wear and maintenance drag, total idle-related impact commonly lands in the mid-to-high four figures per truck. For a deeper breakdown, read our Phoenix EXOair installer guide.
Our Install Process
1) Intake and power profile
We verify truck configuration, idle pattern, and accessory demand before selecting install layout.
2) Mounting and wiring
Our techs mount hardware cleanly, route wiring safely, and protect service access points.
3) Battery and charge validation
We validate charging behavior and startup reserve so drivers can trust next-morning starts.
4) Runtime and handoff
Final checks, controls walkthrough, and operating guidance for owner-operators and dispatch teams.

- Direct phone access to real diesel technicians and dispatch
FAQ
Frequently Asked Questions
How much fuel can an electronic APU save?
How much fuel can an electronic APU save?
Typical savings depend on idle hours and fuel price. Many long-haul operations see meaningful annual fuel reduction by replacing overnight idling with battery-powered cab cooling and hotel loads.
Does EXOair replace all truck idling in every condition?
Does EXOair replace all truck idling in every condition?
No system eliminates every minute of idling in every climate and duty cycle. EXOair is designed to reduce idle dependence for parked comfort and accessory power, especially during routine rest periods.
Can EXOair help with California anti-idle exposure?
Can EXOair help with California anti-idle exposure?
Yes. Lower main-engine idle time can support compliance planning for California routes where heavy-duty idling limits are strict, including the five-minute baseline rule under CARB truck idling requirements.
What about Arizona anti-idling rules?
What about Arizona anti-idling rules?
For Phoenix-area operations, Maricopa County Ordinance P-21 applies a five-minute heavy-diesel idling limit in most circumstances. We can help you plan installs around your route and yard patterns.
How long does an EXOair install take?
How long does an EXOair install take?
Install timing varies by truck setup and electrical condition. Most jobs are completed with a structured intake, mounting, wiring, charging validation, and runtime testing before release.
Do you install for owner-operators and fleets?
Do you install for owner-operators and fleets?
Yes. We support single-truck owner-operators, multi-unit fleets, and phased rollout plans for larger operations.
