Does preventive maintenance keep the manufacturer warranty valid?

Yes. All major brands (Daikin, Mitsubishi Electric, LG, Carrier) require documented preventive maintenance by a certified technician as a condition of their warranty. We provide a signed technical report after each visit that you can present to the manufacturer if needed. Without periodic maintenance, a warranty claim for compressor failure — typically the most expensive repair — may be denied.

How often does a VRF system need maintenance in Chile?

For commercial VRF systems in Chile, we recommend a minimum of two visits per year: one before the summer cooling season (October–November) and one before the winter heating season (April–May). Systems in high-use environments (24/7 operations, dusty areas, coastal locations with salt air) benefit from quarterly visits. Heavy-duty environments like data centers or hospitals require monthly inspection.

Do you service brands you did not install?

Yes. We service all major brands: Daikin, Mitsubishi Electric, LG, Samsung, Carrier, Lennox, York, and Midea. For systems under manufacturer warranty that we did not install, we can provide maintenance aligned with the manufacturer's requirements so your warranty remains valid. We have access to brand-specific diagnostic tools and service manuals.

What is included in the technical report after each visit?

Each visit produces a signed technical report with: date and equipment list inspected, measurements taken (refrigerant pressures, compressor amperage, air temperature delta), anomalies found and their severity, work performed, consumables replaced, and recommendations for the next visit. The report is delivered digitally (PDF) and can be sent to your facilities or property management team.

Can you cover multiple locations across Chile?

Yes. We cover all regions of Chile. For clients with multiple locations (retail chains, hotel groups, clinic networks), we coordinate maintenance schedules centrally and deliver a consolidated report per location. This simplifies facilities management and ensures all sites are covered under a single contract.

What is the response time for an emergency repair under a maintenance contract?

Response times depend on the plan and equipment criticality. For critical equipment (server room cooling, operating room HVAC, refrigerated cold rooms), we can structure a custom SLA with a prioritized on-site response. Response commitments are agreed with each client individually as part of the maintenance contract.
