An AC unit is a closed system, in ideal conditions, freon should never be consumed. However, in practice, refrigerant loss occurs due to micro-cracks at joints, copper pipe corrosion or poor initial installation.

Freon Charging for AC Units - Diagnostics & Precise Refill

5 signs your AC is low on freon

Ice on outdoor unit pipes

A thin layer of ice or frost on the copper pipes of the outdoor unit.

AC blows warm instead of cold air

The difference between set and actual temperature is growing.

Compressor runs non-stop but doesn't cool

The inverter tries to compensate for the lack of refrigerant.

Hissing or crackling from indoor unit

Gas bubbles in the liquid line, a sign of insufficient freon.

Higher electricity bill than usual

The compressor has to work harder to compensate for the freon shortage.

Recognize any of these symptoms?

Call us for diagnostics. We identify the cause and recharge refrigerant the same day.

Freon charging procedure

1

Initial system diagnostics

Pressure and temperature measurement, visual inspection of joints and pipes.

2

Leak detection

Ultrasonic detector and soap solution for precise localization of leaks at joints.

3

System vacuuming

Complete system vacuuming to remove moisture and impurities.

4

Precise scale-based charging

Charging the exact amount of refrigerant gas per manufacturer specifications.

5

Testing and final check

Measuring temperatures and pressures during operation. Verifying everything is within spec.

Refrigerant types

R32 - Newer generation, lower GWP (675), higher energy efficiency

Newer generation refrigerant with lower GWP (675) and higher energy efficiency. Standard for new units.

R410A - Older standard, GWP 2,088, gradually being replaced by R32

Older standard with GWP 2,088. Gradually being replaced by R32 but still common in many systems.

R22 - Outdated, banned for new systems, available only for topping up existing ones

Outdated refrigerant, banned for new systems since 2015. Available only for topping up existing units.

What our clients say

“I called them because my AC wasn't cooling properly. They found it was low on freon, topped it up and cleaned everything in an hour. Night and day difference.”

AC service

“The AC was blowing warm air, and it turned out it was low on freon. The technician quickly found the leak, repaired it and refilled. Everything works like new.”

Frequently asked questions

In a properly functioning system, refrigerant lasts for years without needing a top-up. If your AC is losing refrigerant, it means there is a leak that needs to be found and repaired before refilling.
The cost depends on the gas type (R32, R410A, R22) and the amount needed. Contact us for an accurate estimate, leak diagnostics are included in the price.
Key signs: the AC blows lukewarm instead of cold air, ice forms on the indoor unit, the AC runs but doesn't cool enough, or you hear unusual sounds.
R32 is a newer generation with lower GWP (Global Warming Potential) and better energy efficiency. R410A is an older standard gradually being replaced by R32.
Only if there's a leak, the AC doesn't consume refrigerant on its own. If you notice weaker cooling, there may be a leak that needs to be found and repaired before refilling.

AC not cooling like before?

It may be low on freon. Call us for diagnostics and precise charging.
