Top Signs Your Air Conditioning Needs Repair: Hampshire Homeowners’ Checklist
Warm Air Instead of Cool Air
If your system is blowing warm air when it should be cooling, it’s a sign something’s not right. The issue could be as simple as a blocked filter restricting airflow or as serious as a refrigerant leak.
In Portsmouth, we recently repaired a system in a home office where low refrigerant levels were causing warm airflow. A quick repair and recharge restored full cooling — and prevented damage to the compressor.
Weak or Uneven Airflow
Your air conditioning should deliver a steady, consistent flow of air. If you notice weak airflow from the vents, or if some rooms are cooling while others stay warm, it could be a sign of:
- Blocked ducts or filters
- A failing blower motor
- Damaged or leaky ductwork
Catching airflow problems early can save you from higher energy bills and more serious repairs down the line.
Strange Noises You Haven’t Heard Before
Air conditioning systems should run quietly, especially modern models. Unusual noises — like grinding, banging, or squealing — often indicate a mechanical problem. For example:
- Grinding could mean worn motor bearings.
- Banging may signal loose or broken components.
- Squealing might point to belt or fan issues.
A homeowner in Winchester contacted us after hearing a loud clattering from their outdoor unit. We found a loose fan blade that, if left unchecked, could have caused major damage.
Unpleasant Smells Coming from the Unit
Your AC should never produce a bad odour. Musty smells can indicate mould or mildew growth inside the system — often due to excess moisture or blocked drainage. Burning smells may point to an electrical problem that needs immediate attention.
In one case in Basingstoke, a musty smell turned out to be mould build-up inside the evaporator coil housing. A professional clean not only removed the smell but also improved air quality throughout the home.
Leaks or Moisture Around the Unit
While some condensation is normal, pooling water or refrigerant leaks are not. Moisture can cause damage to your home, while refrigerant leaks can impact both efficiency and safety.
If you spot water or oily residue near your unit, it’s important to call a qualified engineer right away. We’ve helped Hampshire homeowners catch leaks early and prevent costly water damage to floors and walls.
Higher Energy Bills Without Increased Use
If your electricity bill has suddenly spiked but your AC usage hasn’t changed, your system may be working harder than it should. This could be due to clogged filters, worn parts, or refrigerant issues reducing efficiency.
Regular servicing can catch these problems before they lead to both higher running costs and expensive repairs.
Why Acting Early Matters
Delaying repairs can turn a small issue into a major breakdown — and in many cases, damage other parts of your system. A simple refrigerant top-up today could prevent the need for a full compressor replacement tomorrow.
