FAQ

BTU stands for British Thermal Unit. It is a unit of heat; it is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. In HVAC, it measures how much heat an air conditioner can remove from a room per hour.

EER stands for Energy Efficiency Ratio. It is a measure of how efficiently a cooling system operates. It is calculated by dividing the cooling capacity (in BTUs per hour) by the power input (in watts) at a single set temperature. A higher EER means a more efficient air conditioner.

The Star Rating is a system initiated by the Bureau of Energy Efficiency (BEE) in India. It rates the energy efficiency of an appliance, like an air conditioner, from 1 to 5 stars. More stars mean higher energy efficiency, which translates to lower electricity bills.

The primary advantage of a star-rated AC, especially one with a high star rating (like 4 or 5 stars), is significantly lower power consumption. This leads to reduced electricity bills and a smaller carbon footprint, making it both cost-effective and environmentally friendly.

For optimal comfort and energy efficiency, it is recommended to set your air conditioner's thermostat to 24°C to 26°C. Every degree you lower the temperature below this can significantly increase your energy consumption.

The maximum permissible distance varies by manufacturer and model, but a typical range is around 15 to 25 meters (50-80 feet). Exceeding this distance can lead to a drop in cooling performance and efficiency as the compressor has to work harder.

Variable Refrigerant Flow (VRF) systems are sophisticated, large-scale HVAC systems. They use a single outdoor condensing unit connected to multiple indoor units, each capable of individual temperature control. The system varies the refrigerant flow to each indoor unit based on demand, making it extremely energy-efficient for large buildings with diverse heating and cooling needs.
