If your air conditioning is running but not cooling properly, a low refrigerant level is often the cause — and “regassing” is the fix. Here’s what it actually involves and what it typically costs.
What Does "Regassing" Actually Mean?
Air conditioning systems use refrigerant gas to move heat out of a room. Over time, or due to a small leak, refrigerant levels can drop — reducing cooling performance even though the system still switches on and runs normally. Regassing means topping up (or fully recharging) that refrigerant to restore proper performance.
Signs You Might Need a Regas
- The system runs but barely cools the room
- Cooling has gradually gotten weaker over months or years
- Ice forming on the indoor or outdoor unit
- Longer run times to reach the same temperature as before
What Typically Affects the Cost
Price depends on the refrigerant type your system uses, how much needs adding, and whether a leak needs finding and repairing first — topping up a system with a genuine slow leak without fixing the leak itself is only a temporary fix, so a proper diagnosis matters more than just adding gas.
Why a Proper Diagnosis Matters First
Regassing a system with an underlying leak just means you’ll be back in the same position within months. Our engineers check for leaks as standard before recommending a regas, so you’re paying for a lasting fix, not a temporary top-up.
