To accurately measure aircon superheat, you’ll need the equipment, a pressure gauge, a thermometer or thermocouple to measure suction line temperature, and a refrigerant pressure-temperature (P-T)…

A professional aircon technician needs a diverse range of tools and equipment for efficient and safe repairs. Essential tools include a multimeter, refrigerant gauges, vacuum pump, leak…

A Delta T report, which measures the temperature difference between two points (like supply and return air in HVAC), is important after charging a system…

A Delta T report is important after installing a new air conditioner because it helps assess the system’s efficiency and identify potential problems. Delta T, the…

Highlights of Aircon Overcharged Refrigerant 1. AC Not Cooling Properly 2. AC Shuts Off Very Quickly 3. High Energy Bills After Recent Service If your…

The compressor is one of the most important components in a residential air conditioning system. It bears the responsibility of raising the pressure of the…

Overcharging an AC system, meaning adding too much refrigerant, can lead to compressor failure. The excess refrigerant creates high pressure, potentially damaging the compressor’s internal components…

Charging a refrigerant system using a scale refers to a method of accurately determining and adding the correct amount of refrigerant to an HVAC system, often…

Charging an aircon without a scale can lead to several issues, including compressor damage, reduced system efficiency, and potential leaks. Undercharging can cause insufficient cooling and damage…

Charging an air conditioner using vapour pressure readings is a complex process that requires specialised knowledge and tools. It involves carefully monitoring pressures on both the high…
