Understanding AC Servicing and Potential Scams

As summer approaches, many homeowners are gearing up to service their air conditioning units, coolers, and fans that have been idle for several months. It's common to call in technicians for air conditioner maintenance to ensure everything is clean and functioning well. However, during these servicing sessions, technicians often claim, "Sir, the AC is leaking gas; it needs a refill." This statement can sometimes be a tactic for scamming unsuspecting customers.

Many individuals are unaware of the correct gas pressure levels for their air conditioning units, making it challenging to verify if a gas leak is genuine or if the technician is simply trying to sell a refill. This is how scams related to AC gas leaks can occur.

Identifying AC Gas Leak Scams

When a technician services your air conditioner at home, they may inform you of a gas leak that requires refilling. While this could be a legitimate issue, there are instances where technicians might mislead you into believing there is a leak when there isn't one. To protect yourself, it's crucial to understand the appropriate gas pressure levels for your air conditioning unit.

Experts in air conditioning installation indicate that the standard pressure levels for a 1.5-ton air conditioner are as follows:

Refrigerant Running Pressure (PSI) Close Pressure (PSI)
R32 130–140 240–280
R410 130–140 240–280
R22 60–65 Around 150

Measuring AC Pressure: A Step-by-Step Guide

How to Measure Pressure?

Before the technician begins servicing your AC, turn it on and request that they check the gas pressure while the unit is operational. Compare this reading to the "Running Pressure" values listed in the table above.
Afterward, switch off the AC and take another pressure reading, comparing it to the "Close Pressure" values.
If both readings are within the expected ranges, there is likely no need for a gas refill.
Being informed about the running and closing pressure of your AC can significantly help in avoiding scams related to gas leaks.
