My AC is blowing warm air — what is wrong?

The most common causes are low refrigerant from a small leak, a failed capacitor or fan, a blocked condenser coil or a faulty control board. A diagnostic visit will identify which it is.

Is it worth repairing an older unit?

If the unit is under about 10 years old and the repair is not a major compressor failure, repair is usually the better value. We will always give you an honest repair-versus-replace recommendation with costs.

Do you repair units you did not install?

Yes. We service and repair systems from any installer and any brand.

Why it pays off

What you actually get from doing this properly

Anyone can quote you a price. Here is the difference a proper air conditioning fix & repair makes once the van has driven away — in plain terms, from jobs we do across London every week.

Talk it through with an engineer

Cold air back the way it should be

Weak airflow and lukewarm output usually trace back to one or two faults. Once they are fixed properly, the room cools the way it did when the system was new.

Small problems caught early

A slight refrigerant leak or a tired fan bearing is cheap to sort now and expensive to ignore. We flag what is starting to wear so you can plan rather than react.

Straight answers on repair vs replace

If a repair is good value, we will do it. If the unit is on its last legs, we will tell you plainly and show you the numbers — the choice stays yours.
