Service FAQs

Do you offer design and expansion support (load calculation, zoning, BMS)?

Yes. We provide heat-load surveys, indoor unit selection, diversity planning, branch/selector box placement, pipe routing, and basic BMS coordination. For expansions, we validate outdoor capacity, pipe lengths, and addressing before proposing add-ons.

How do you ensure oil return on long vertical risers and long pipe runs?

We follow brand guidelines for pipe sizing, velocity, and oil traps on vertical lifts, maintain minimum connected load, and verify superheat/subcooling during commissioning. Periodic health checks under AMC confirm stable oil return and compressor safety.

Can you retrofit from older R22 systems to VRF?

Yes—after a site survey. We check electrical capacity, heat-load, and existing piping runs. Because R22 mineral oil is incompatible with R410A/R32, we typically do not reuse old line sets; we recommend new copper, fresh insulation, nitrogen-purged brazing, deep evacuation, and brand-specified charging.

How quickly can you start a large repair?

After diagnosis and approval, we schedule parts procurement and a repair window; emergency options are available in select cities.

Do you provide site health reports?

Yes—AMC and corporate clients receive periodic health reports and recommendations.

Do you support BMS integration checks?

We perform basic checks and coordination with your BMS vendor where applicable.

My ceilings lack service access panels—can you still maintain cassettes?

Regular access is essential. We can coordinate access panel creation with your interiors team as an add-on.

Can you expand my existing VRF with additional indoor units?

Subject to outdoor module capacity, piping design, and brand guidelines. We survey and propose options.

How often should a VRF system be serviced?

Quarterly for high-use commercial environments; at least every six months for lower-use spaces.

Do you offer after-hours or Sunday service for commercial sites?

Yes—available in many cities with a small surcharge depending on access and building rules.

Do you service branch selector boxes and EEVs?

Yes—cleaning, checks, and replacements where needed; quotes depend on access and model.

Can you locate small refrigerant leaks?

We use appropriate methods for the system and conditions, then repair and re-test before charging.

Will you vacuum to microns before charging?

Always. Moisture and non-condensables damage compressors and valves; deep evacuation is mandatory.

Can you fix recurrent communication errors between indoor units and outdoor modules?

We check polarity, addressing, cable health, controller settings, and PCB status, then rectify the root cause.

Do you handle multi-brand VRF systems?

Yes. We work across leading brands; specific parts availability may vary by city and model.
