OCCUPANCY SENSORS
What is an Occupancy Sensor?
An occupancy sensor in an HVAC system is a device that identifies the presence of individuals in a room. This allows the HVAC system to modify heating or cooling based on whether the space is occupied. Essentially, it activates the system when people are present and deactivates it when they leave, leading to energy savings.
These sensors utilize technologies such as infrared or ultrasonic waves to detect body heat or movement, thereby prompting the HVAC system to turn on or adjust settings upon someone entering a room. By operating the HVAC system only when necessary, occupancy sensors play a significant role in conserving energy in buildings.
Common Types of Occupancy Sensors Used in the HVAC Industry:
- Passive Infrared (PIR) Sensors: The most widely used type, which detects variations in infrared radiation emitted by people.
- Ultrasonic Sensors: These emit sound waves and detect reflections to sense movement, even through obstacles.
- Dual-Technology Sensors: These combine both PIR and ultrasonic capabilities for enhanced accuracy.

What services do you provide?▼
We offer end-to-end HVAC services, including system design, installation, turnkey project execution, chiller and VRV/VRF system solutions, ducting, fabrication, automation, electrical works, and industrial refrigeration. Whether it’s a small requirement or a large-scale project, we deliver reliable, energy-efficient, and cost-effective solutions.
Do you provide customized HVAC solutions?▼
Yes. Every client has different needs, and we specialize in offering tailored services—ranging from inspection and preventive maintenance to upgrades like insulation replacement, motor servicing, and specialized fabrication. Our customized approach ensures you get solutions that truly fit your operations.
What common AC problems do you address?▼
We handle issues like water leakage (caused by clogged drains or trays), poor airflow (due to dirty filters or fan faults), and cooling failures (caused by refrigerant leaks, outdoor unit problems, or electrical issues). Our expert technicians ensure quick, lasting fixes for all major and minor problems.
How can I reduce AC energy consumption?▼
We recommend regular servicing, using the timer function, keeping rooms sealed, and setting the temperature to 24 °C for maximum efficiency. Upgrading to inverter ACs with higher star ratings is also an effective long-term solution for reducing energy bills.
What is the lifespan of an AC system?▼
On average, centralized HVAC systems last 10–15 years, while room or split AC units run efficiently for 3–6 years under normal daily usage. With regular servicing and proper care, their lifespan can be extended.
How do you ensure quality in your HVAC projects?▼
Every project we undertake goes through strict quality checks at every stage—right from design to installation and maintenance. We use trusted brands, follow industry standards, and our team of skilled engineers ensures that the systems are safe, reliable, and long-lasting.
Do you provide consultation before starting a project?▼
Yes. We believe every client has unique requirements, so we offer detailed consultation and site inspections before starting any project. This helps us understand your needs better and design a solution that balances performance, cost-efficiency, and sustainability.
Can businesses upgrade their existing HVAC systems with you?▼
Absolutely. We specialize in retrofitting and upgrading older HVAC systems with the latest technology. Whether it’s energy-efficient chillers, modern ducting, or smart automation, we help businesses transition to advanced systems without disrupting ongoing operations.
