Chassis Air Conditioning (Dash A/C) Service in Arcadia, CA
Dash air is what keeps the driver comfortable on a 100-degree run through the Inland Empire, and it's usually the first thing to quit at exactly the wrong time. Long refrigerant lines and a big cab make motorhome chassis A/C harder than car A/C — which is why plenty of general shops send these jobs to us.

Symptoms we hear most
- Air blows but never gets cold, or only cools at highway speed
- Cold at first, then warm after twenty minutes
- Weak airflow or a blower that works only on high
- Squeal or clunk from the compressor when A/C is switched on
- Musty smell from the vents
How we diagnose and repair it at the shop
- 1
Measure before adding refrigerant
We read high and low side pressures and vent temperatures. Topping off a leaking system just wastes your money and vents refrigerant.
- 2
Find the leak
Dye and electronic leak detection across the long line runs, condenser, evaporator, and fittings that motorhomes are notorious for.
- 3
Repair, evacuate, recharge
We repair the fault, pull a deep vacuum to remove moisture, and recharge by weight — then verify vent temperature on a road test in real traffic.
Why VJ's for this repair
We handle both the dash A/C and the rooftop units, so if your coach is hot up front and in the back, one visit fixes both instead of two shops pointing at each other.
