Freon refill cost guide

Is your air conditioner not cooling properly? It might be low on Freon. Find out the Freon refill cost and when you might need it.

If you’re relying on your air conditioner when the temperatures hit the 30s, it can be very frustrating to find it throwing out warm air. One of the reasons why it’s doing this could be that it’s low on Freon. To get it back to cooling optimally, you may need to refill (or re-gas) it. But, what does Freon refill cost?

Freon recharge costs can vary depending on how much your A/C unit needs to be refilled and the type of gas it needs. Also, they will also depend on the size of your air conditioning unit.

Here’s a summary of what your air conditioner Freon refill cost might be.

Depending on the size of your air conditioning unit, you can expect to pay around £75 – £450 for your air conditioner Freon refill cost. However, the price may go up or down based on which gas you’re using and how much you need.

For example, if you have a 2.5 ton A/C unit that only needs a top-up as part of your aircon service to keep it running optimally, you might spend £95 for R410A.

However, for the same sized unit, if you have a major leak, you could be spending £700 – £1,100. At this point, it may be cheaper to replace the unit.

Also, as we mentioned, your Freon recharge cost might vary based on what type it is – R22, R32, or R410A. R22 is not used widely as it damages the ozone layer. However, it’s still found in older systems. R32 and R410A are more popular, as they don’t affect the ozone layer as much.

So, R22 Freon refill cost per unit could be in the range of £150 – £450. On the other hand, R410A would cost you around £75 – £240.

There are a few signs that could tell you it’s time to re-gas your aircon.

  • Your A/C is taking longer to heat up the room
  • It is throwing warm air instead of cold
  • The electricity bills are higher as the unit becomes inefficient
  • The refrigerant coils are starting to freeze

If you’re experiencing one or more of these, it might be time to look up A/C Freon refill costs!
