How to Check Your Home AC Coolant Level?

You don’t need to be an f-gas certified service engineer to be able to check the refrigerant level in your system. Do it in 20 minutes or less with us!

Here Are 5 Steps to it With EASE

1. Determine The Refrigerant Type First-

Check the type plate on your installation. It contains information such as installation number, global warming potential, number of circuits, and refrigerant type.

2. Take The Pressure Reading-

Almost every system is equipped with pressure gauges, showing the suction and discharge pressure. Suction pressure is low pressure, and discharge pressure is high pressure.

If your system has no gauges, you can find the suction and discharge pressure in the documentation.
In such cases, careful discretion is advised. We recommend getting it done by certified personnel. Schedule AC repair service in Murrietta, CA today.

3. Know The Condensation or Evaporation Temperature-

The coolant has different condensation and evaporation temperatures at varying pressures. A refrigerant slider determines these temperatures.

Set the slide on ‘dew’ mode to know the evaporation temperature and type in the low pressure.

Set the slide on ‘bubble’ mode to calculate the condensate temperature. Type in the high pressure. The second box will show the corresponding evaporation temperature. Write down these temperatures.

4. Measure The Temperature on Your Installation-

With the help of a digital thermometer, measure the temperatures on the installation. Superheating can be measured on the suction pipe just before the compressor inlet. Subcooling is measured right before the expansion valve.

5. Calculate Superheating And Subcooling Temperature-

After having all the data required to calculate the subcooling and superheating, we can calculate the following.

Superheating= temp. suction pipe- evaporation temperature
Subcooling= condensation temp- temp. discharge pipe

If the temperatures range within the 10k-5k range, the system operates with the right amount of coolant. If it isn’t, we do not recommend doing it yourself.

Condition of Your System

Subcooling and superheating are two important terms in cooling techniques. All mediums evaporate or condensate at a given temperature. To ensure that everything is evaporated in a cooling circuit, the temperature is set slightly higher, such as 110 degrees centigrade. But water at sea level condensates or evaporates at 100 degrees centigrade. This temperature difference of 10K is called superheating.

In condensation, set the temperature to a lower 95 degrees centigrade.
The temperature difference for superheating and subcooling must be around 10K and 5K, respectively. Too much superheating and too little subcooling suggest insufficient refrigerant in the system and vice versa. Too much subcooling and little superheating indicate too much refrigerant in the system.
