HVAC Systems We Specialize In

Our team is trained and experienced across the full spectrum of commercial and industrial HVAC equipment. Below are the core system types we install, commission, repair, and maintain.

  1. Precision Air-Conditioning Units (PACU)

Designed for high-availability environments such as server rooms, data centers, and telecommunications facilities. Infinite Systems supplies and installs PACUs engineered for continuous duty cycles, tight temperature and humidity control, and N+1 redundancy configurations. Our engineers size units for IT heat loads, specify appropriate precision cooling models, and commission systems to comply with ASHRAE A1/A2 data center environmental standards.

  1. Chilled Water Systems

We design, install, and service complete chilled water HVAC systems — including chillers, cooling towers, air handling units (AHU), fan coil units (FCU), chilled water pumps, and piping networks. Ideal for large commercial buildings, malls, hospitals, and multi-tenant office towers requiring high-capacity centralized cooling. Our engineers optimize chiller plant configurations for efficiency, redundancy, and future load growth.

  1. VRV / VRF Multi-Split Systems

Variable Refrigerant Volume (VRV) and Variable Refrigerant Flow (VRF) systems deliver flexible, energy-efficient cooling and heating for mid-size commercial buildings, office fit-outs, and mixed-use developments. Infinite Systems provides full design, supply, installation, and commissioning services — with capability to integrate VRV/VRF into building management systems (BMS) for centralized control, scheduling, and monitoring.

  1. Variable Frequency Drives (VFD)

VFDs regulate motor speed on fans, pumps, compressors, and air handling units to match actual demand — typically delivering 20–50% energy savings on motor-driven HVAC loads. We supply, install, program, and maintain VFDs from leading brands, handling parameter configuration, panel integration, harmonic mitigation, and ongoing performance monitoring. VFD retrofits on existing HVAC motors are among the fastest-payback energy investments available to Philippine building owners.

  1. Industrial Fans & Blowers

Infinite Systems supplies and installs centrifugal fans, axial fans, inline fans, roof ventilators, and industrial blowers for ventilation, process cooling, fume exhaust, and air distribution. We handle industrial-scale installations in warehouses, manufacturing plants, commercial kitchens, multi-level car parks, and utility rooms — ensuring correct airflow sizing per ASHRAE and SMACNA standards, appropriate acoustic performance, and structural mounting.

  1. Mechanical Ventilation Systems

Proper ventilation is essential for indoor air quality, occupant health, fire safety, and regulatory compliance. Infinite Systems designs and installs mechanical ventilation systems for car parks, basements, toilets, kitchens, server rooms, clean rooms, and general office spaces. We comply with the Philippine Mechanical Engineering Code and ASHRAE 62.1 standards for fresh air rates and air change requirements per space type.

  1. Motor Control Systems

Motor control is the backbone of HVAC automation. We design and build Motor Control Centers (MCC), Direct-On-Line (DOL) starters, star-delta starters, soft starters, and VFD panels — governing chillers, pumps, fans, compressors, and AHU drives. Our electrical engineers ensure proper motor protection, interlocking logic, and integration with building management and SCADA systems.

  1. Air Handling Units (AHU) & Fan Coil Units (FCU)

Infinite Systems installs and maintains AHUs and FCUs for central and distributed HVAC systems. Services include coil cleaning, belt and bearing replacement, drain pan cleaning, filter changeout, damper actuator servicing, and full AHU refurbishment — restoring peak performance to aging systems without full replacement costs.

Frequently Asked Questions — HVAC Solutions Philippines

Q1: What HVAC systems does Infinite Systems install in the Philippines?

Infinite Systems installs Precision Air-Conditioning Units (PACU), Chilled Water Systems (chillers, AHU, FCU), VRV/VRF Multi-Split Systems, industrial fans and blowers, mechanical ventilation systems, and Motor Control Centers — across commercial, industrial, and institutional facilities nationwide.

Q2: Do you provide HVAC services outside Metro Manila?

Yes. Infinite Systems provides HVAC installation, maintenance, and repair services nationwide — including Cebu, Davao, Iloilo, Pampanga, Laguna, Cavite, and other key growth areas in the Philippines.

Q3: What is a Precision Air-Conditioning Unit (PACU) and when is it used?

A PACU is a specialized cooling system designed for environments requiring strict temperature and humidity control, such as server rooms, data centers, and telecommunications facilities. Unlike standard air-conditioners, PACUs operate continuously and deliver precise environmental conditions 24/7 to protect critical IT equipment.

Q4: What is the difference between VRV and VRF HVAC systems?

VRV (Variable Refrigerant Volume) is Daikin’s proprietary term; VRF (Variable Refrigerant Flow) is the generic industry term. Both refer to the same multi-split technology that varies refrigerant flow to multiple indoor units from one outdoor unit — offering flexible zoning, energy efficiency, and quiet operation. Infinite Systems installs and services both.

Q5: What is a VFD and how does it save energy in HVAC systems?

A Variable Frequency Drive (VFD) adjusts the speed of electric motors (fans, pumps, compressors) based on real-time demand. Instead of running at full speed constantly, VFD-controlled motors ramp up or down as needed — reducing energy consumption by 20–50% compared to fixed-speed systems, directly lowering your monthly electricity bill.

Q6: Do you offer preventive maintenance contracts for HVAC systems?

Yes. Infinite Systems offers structured preventive maintenance (PM) contracts for all HVAC system types. Our PM programs cover periodic inspections, coil and filter cleaning, lubrication, calibration, and parts replacement. Contracts are available on monthly, quarterly, semi-annual, or annual schedules tailored to your facility’s needs.

Q7: Can you retrofit an existing HVAC system with a VFD or VRV/VRF?

Yes. We provide system retrofit and upgrade services. We can install VFDs on existing motors to improve energy efficiency, or replace outdated systems with modern VRV/VRF multi-split systems — reducing energy consumption and improving comfort control without a complete building overhaul.

Q8: What is a Chilled Water System and is it right for my building?

A Chilled Water System uses a central chiller plant to produce chilled water distributed to AHUs and FCUs throughout a building. It is ideal for large commercial buildings, malls, hospitals, and hotels requiring high-capacity centralized cooling. Infinite Systems designs, installs, and maintains complete chilled water HVAC plants.

Q9: Do you handle  PRC-licensed engineer sign-offs for HVAC projects?

Yes. Infinite Systems employs PRC-licensed Mechanical Engineers who prepare engineering drawings, specifications, and documentation compliant with the Philippine Mechanical Engineering Code.

Q10: How do I know what size HVAC system my facility needs?

Proper sizing requires a heat load calculation based on floor area, occupancy, equipment loads, building orientation, and insulation. Infinite Systems conducts professional heat load assessments to determine correct system capacity — preventing under-sizing (inadequate cooling) and over-sizing (wasted energy and higher capital cost).
