A DC split AC system that's running well is easy to ignore. One that's been ignored for a few seasons starts to show it — reduced cooling output, longer run times to reach temperature, coils that are working harder than they should. Annual service keeps it running the way it did on day one.
Voltara Systems provides DC air conditioning inspections and tune-ups for vans, RVs, and specialty vehicles in Long Beach, CA.
Indoor coil condition and airflow. Outdoor condenser coil cleaned if needed. Dirty coils are the most common cause of reduced performance.
System operating pressures checked against spec. If charge is low, we diagnose the leak — we don't just top it off and call it done.
Electrical connections at the unit and battery supply. DC wiring condition, fuse integrity, and voltage at load — all checked before sign-off.
Once per year is the minimum. Before summer is the obvious time — you want to know the system is ready before the first heat wave. If you're using the vehicle year-round, twice yearly keeps everything ahead of problems.
Filter condition is checked and replaced if needed. Full cooling performance test before we sign off. You leave knowing exactly what state the system is in.

The clearest signs: it takes longer to cool the space than it used to, it cycles on and off more frequently, it produces less airflow, or it trips the fuse under load. Any of these warrants a look before the next heat wave.
Not normally — a properly installed closed system doesn't consume refrigerant. If the charge is low, it means there's a leak somewhere, and that needs to be diagnosed and repaired, not just topped off.
Yes. We'll inspect what's there, assess the installation quality, and handle whatever it needs — whether that's a simple tune-up or correcting an installation issue from the original build.
