What is the most common problem with an air conditioner?

Most breakdowns are caused by a handful of common issues. If you notice any of these signs, it’s time to call in an expert:

1. Water Leaking Indoors

Usually caused by a blocked condensate drain pipe or a failing condensation pump. We flush the system and replace faulty pumps.

2. Not Cooling or Heating

Often a sign of low refrigerant gas (which means there is a leak) or a faulty compressor. This requires an F-Gas engineer to test the system.

3. Bad Smells

A musty or damp smell indicates bacteria and mould build-up on the indoor coil. A deep chemical clean will resolve this safely.

4. Flashing Lights / Errors

Modern units have self-diagnostic boards. A flashing light usually means a sensor failure or a communication error between indoor and outdoor units.

Before you call us: What is the 3-minute rule for aircon?

If you just turned your air conditioner off, you must wait at least 3 minutes before turning it back on. This is a built-in safety feature to protect the compressor from damage due to high pressure. If your unit doesn't blow cold air immediately after turning it on, wait 3 minutes. If it still doesn't work, contact us for a professional repair!

Is it worth it to repair an air conditioner?

If your unit is relatively new and the repair cost is reasonable, a repair makes financial sense. However, if your system breaks down constantly, upgrading might be a better investment. We offer energy-efficient replacements on our air conditioning installation Cardiff page.

If you install a new system with us, you receive a 5 to 10-year parts warranty. Please note: this long-term warranty is strictly subject to annual servicing.

Frequently asked questions

How much would it cost to fix an aircon?

The cost depends entirely on the fault. Simple issues like a blocked drain might only cost our standard call-out fee. Major repairs like replacing a compressor will cost more. We always diagnose the issue first and give you a fixed quote before starting major work.

Why is my air conditioner blowing warm air?

This is typically caused by low refrigerant levels (indicating a leak), a heavily clogged air filter restricting airflow, or a failing outdoor compressor. Our local engineers can quickly identify the exact cause and resolve it on-site.

How long does an air conditioning repair usually take?

Most standard repairs, such as clearing blockages or fixing minor leaks, are completed within 1 to 2 hours. If a specific manufacturer part needs to be ordered, we will secure your system and return promptly to finish the job.

My portable air conditioning unit broke, do you repair these?

No, we specialise strictly in fixed, built-in "split system" air conditioning units for buildings. We do not repair portable air conditioning unit Cardiff requests, as these are generally cheaper to replace than to repair.
