All-season parking climate control means a single fleet specification that handles -30°C overnight cold to +48°C summer heat without engine idling at any point in the year. The architecture combines a battery parking AC (cooling) with a diesel night heater (warming) sharing the same chassis but separate energy paths.

Why a single 'all-season' spec matters for fleets

Standardising one combined system across the fleet simplifies purchasing, training, spare-parts and driver experience. Mixed-spec fleets (some with AC, some with heater) create operational friction and driver dissatisfaction.

Architecture — separate energy paths

Cooling path: 280 Ah LiFePO4 auxiliary battery → DC fuse panel → parking AC. Heating path: main fuel tank pickup → diesel heater → cabin warm air outlet. Two independent thermostats, one combined HMI panel optional.

Recommended model bundles

Class-7/8 sleeper: VS02 PRO 24V parking AC + 5 kW diesel heater. Class-3/5 box truck: ZH 1000 12V or VC 1000 24V + 2 kW heater. RV / motorhome: VS02 PRO 24V + 2 kW heater + shore-power inverter charger.

Total install time and cost

Combined system: 8–10 hours single-day install at a qualified upfitter. Hardware $2,800–$3,800 + labor $700–$1,000 = $3,500–$4,800 turnkey per vehicle.

Operating cost — annual

Summer cooling: $0 marginal energy cost (battery recharged during driving). Winter heating: $150–$400 diesel per truck per winter. Total: vastly less than the $1,500–$3,000/year displaced engine idling.

Fleet rollout

Vethy supports 25-unit minimum fleet specifications with bundled pricing, common spares, and OEM-style technical support. Email sales@vethy.com or call +86-532-87729918 for combined heating + cooling kits, solar/shore-power packages and CIF pricing within 24 hours.

Frequently asked questions

Can one HMI control both heating and cooling?

Optional combined HMI is available for fleet orders. Standard kit ships with two independent controllers.

Will the heater drain the parking AC battery?

No — heater runs on its own small 12V battery or starting battery with LVD; AC has its own auxiliary bank.

Do I need shore power if I have an all-season system?

Not strictly required. Shore power accelerates AC battery recharge but the alternator handles recharge during normal driving.

How long does the install take?

Single-day at a qualified shop. Combined kit is plug-and-play with chassis-specific brackets.

Is 'all-season' marketing or real?

Real — Vethy customers in Scandinavia, Canada, Middle East and Australia all run the same combined platform year-round.

Does Vethy offer fleet-wide standardisation support?

Yes — engineering review of your existing fleet and a single recommended spec across mixed chassis. Email sales@vethy.com or call +86-532-87729918 for combined heating + cooling kits, solar/shore-power packages and CIF pricing within 24 hours.
