Every VRF Brand, Serviced to Its Design Capacity
One outdoor unit, dozens of indoor units, and an entire building depending on both. Airam services LG Multi V, Mitsubishi Electric City Multi, Toshiba and Samsung DVM systems across Chennai — per-IDU cleaning, ODU health audits and capacity balancing that keeps every zone at its design temperature. Site-visit quotes in writing, GST invoices, up to 90-day warranty on repairs.

Signs you need this service
Uneven cooling between zones
Cabins on one floor freeze while the far wing sits at 30°C — a sign refrigerant distribution has drifted from design and needs rebalancing.
ODU tripping at peak heat
Outdoor modules cutting out during 40°C afternoons usually mean a choked condenser coil or a compressor stage working beyond its limits.
Error codes on multiple IDUs
Several indoor units flashing faults at once points to a communication bus or refrigerant circuit problem, not one failed unit.
Electricity bills creeping up
A VRF running out of balance draws more power every month as compressors overwork to cover starved zones.
Corrosion on coastal ODUs
Sea air near the coast eats condenser fins first — white or green deposits on the coil mean treatment is overdue.
Water stains under ceilings
Blocked condensate drains in cassette and ductable IDUs stain false ceilings before they short anything, and monsoon damp accelerates both.

Why it’s worth doing properly
Fluent in four VRF platforms
LG Multi V, Mitsubishi Electric City Multi, Toshiba and Samsung DVM each run their own controls, fault logic and service procedures. Our technicians work across all of them, so a mixed-brand building needs one vendor, not four.
Capacity balancing, not just cleaning
We measure what each zone actually receives against what the system was designed to deliver, then correct settings, valves or piping until the numbers match. Clean coils alone never fix a starved wing.
Built on service-floor experience
Our founder spent years on service calls in his father's AC business before starting Airam. That discipline shows in how VRF jobs are documented — readings logged, quotes in writing, nothing verbal.
Chennai-proofed maintenance
Coastal salt air corrodes ODU coils and voltage fluctuations stress inverter boards, so we check for both on every visit. Anti-corrosive treatment is recommended where the audit shows fin damage, not by default.
How the visit goes
Book a site visit
Tell us the brand, IDU count and floor layout, and we schedule an engineer — same-day slots when available.
Audit every unit
We inspect each IDU and ODU, log refrigerant readings and error histories, and map cooling delivery zone by zone.
Quote, then work
You get a written, itemised quote; on approval we service, repair and rebalance with per-unit sign-off.
Report and warranty
You receive a system health report, a digital GST invoice and up to 90 days of warranty on repair work.
