5 Signs Your Air Conditioning Needs a Service

As the warmer months roll in across Teesside, your air conditioning system becomes a vital part of keeping your home comfortable. But just like your boiler or car, your AC needs regular attention to stay in top condition.

If your system isn’t performing like it used to, it might be time for a service. Here are five clear signs your air conditioning needs professional attention.

1. It’s Not Cooling Like It Used To

If you’ve noticed that your air conditioner is blowing warm or slightly cool air but not enough to keep the room comfortable, it’s a clear sign something’s off.

Common causes include:

• Low refrigerant levels
• Blocked filters
• Dirty coils
• Faulty thermostats

A service can pinpoint and fix the issue before it gets worse – or more expensive.

2. Strange Noises or Vibrations

Modern air conditioning systems should run quietly. If you’re hearing:

• Rattling
• Humming
• Grinding
• Banging

…it could mean loose components, a worn fan motor, or debris in the unit. Left unchecked, these small issues can lead to major repairs.

3. Bad Smells Coming from the Unit

Musty, damp, or even burning smells from your AC system are never normal.

These odours could signal:

• Mould or bacteria build-up in the filters or ducts
• Burnt-out wiring

A full clean and inspection during a service can eliminate smells and protect your indoor air quality.

4. Higher Energy Bills Than Usual

If your electricity bills are creeping up even though you’re not using your AC more than usual, inefficiency may be the culprit. A dirty or poorly maintained system has to work harder to cool your home.

Regular servicing can:

• Improve performance
• Reduce strain on the system
• Help lower running costs

5. It’s Been Over a Year Since Your Last Service

Even if everything seems fine on the surface, air conditioning systems should be serviced at least once a year, especially before summer kicks in. Think of it as a health check for your system.

Servicing helps:

• Spot issues early
• Maintain manufacturer warranties
• Extend the life of your unit
