Common Air Conditioning Problems (And What They Cost to Fix)

1. AC Not Turning On

Common causes: Tripped circuit breaker, blown fuse, faulty isolator switch, dead remote batteries, or a failed circuit board.

For a detailed breakdown of AC repair vs replacement costs, see our guide on split system installation costs in Brisbane.

What we do: We check the electrical supply first — circuit breaker, isolator switch, and power point. If the supply is fine, we check the indoor and outdoor units for electrical faults. Most of the time, it’s a tripped breaker or a faulty isolator. Learn more about resetting circuit breakers safely.

Typical cost: $150–$250

2. AC Not Cooling Properly

Common causes: Dirty filters, low refrigerant (gas leak), dirty outdoor coils, blocked airflow, or the unit is too small for the room. Read our detailed guide on why your AC is running but not cooling.

What we do: We check the filters first — dirty filters are the #1 cause of poor cooling. If filters are clean, we check the outdoor coils and refrigerant levels. If there’s a refrigerant leak, we find the leak, repair it, and regas the system.

Typical cost: $150–$400 (more if there’s a refrigerant leak)

3. AC Leaking Water Indoors

Common causes: Blocked drain pipe, dirty indoor unit (causing ice buildup), incorrect installation angle, or a cracked drain tray.

What we do: We clear the blocked drain pipe and flush the system. If the indoor unit is dirty, we clean it thoroughly. If the drain tray is cracked, we replace it.

Typical cost: $150–$350

4. AC Making Strange Noises

Common causes: Loose fan blades, worn fan motor bearings, rattling panels, or a failing compressor.

What we do: We identify the source of the noise. If it’s a loose panel, we tighten it. If it’s the fan motor, we replace the bearings or the motor. If it’s the compressor, we assess whether repair or replacement is more cost-effective.

Typical cost: $150–$350 (compressor issues cost more)

5. AC Smelling Bad

Common causes: Mould and mildew buildup in the indoor unit, dirty filters, or a blocked drain pipe causing stagnant water.

What we do: We deep-clean the indoor unit, clean or replace the filters, and clear the drain pipe. We also check for mould in the ductwork (for ducted systems).

Typical cost: $150–$300

6. Refrigerant Leak (Needs Regas)

Common causes: Corroded copper pipes, loose fittings, vibration damage, or manufacturing defects.

What we do: We find the leak using specialised equipment, repair it, then vacuum and regas the system with the correct type and amount of refrigerant. We can’t just top up the gas — we need to fix the leak first.

Typical cost: $250–$500

Pro tip: If your AC needs regassing more than once every few years, there’s a persistent leak. It might be more cost-effective to replace the unit. Check the ARCtick website for more information on refrigerant handling regulations.

7. Compressor Failure

Common causes: Age (15+ years), lack of maintenance, electrical faults, or refrigerant issues.

What we do: We assess whether the compressor can be repaired or needs replacing. Compressor replacement is expensive — often $800–$1,500 including parts and labour. If the unit is old, we’ll usually recommend replacement instead.

Typical cost: $500–$1,500

8. Fan Motor Replacement

Common causes: Age, worn bearings, electrical faults, or water damage.

What we do: We replace the faulty fan motor with a new one. We test the system afterwards to make sure everything is working correctly.

Typical cost: $250–$500

9. Circuit Board (PCB) Failure

Common causes: Power surges, age, moisture damage, or component failure.

What we do: We replace the faulty circuit board. For older units, PCBs can be hard to source — we’ll let you know if this is an issue.

Typical cost: $300–$600

Emergency vs. Non-Emergency AC Repairs: What’s the Cost Difference?

Not all AC problems need immediate attention. Here’s how to prioritise and what you’ll pay:

Emergency Repairs (Same-Day Service)

When to call immediately:

• Burning smell or smoke — electrical fault, fire risk
• Water leaking onto electrical components — short circuit risk
• Loud banging or grinding noises — compressor or motor failure imminent
• AC stops working in extreme heat — health risk for elderly or infants
• Gas smell (rare, but serious) — refrigerant leak in enclosed space

Emergency pricing:

• Same-day service: $150/hour (no extra charge if booked before 2pm)
• After-hours (6pm–8am): $180/hour (1.5x rate)
• Weekend/public holiday: $180/hour
• No call-out fee — even for emergency calls

Non-Emergency Repairs (Schedule Within a Week)

When you can wait:

• AC running but not cooling well — still working, just inefficient
• Minor water leak — small drip, not flooding
• Slight increase in energy bills — efficiency drop, not broken
• Unusual but quiet noises — rattling, clicking (not grinding)
• Bad smell when first turned on — mould buildup, needs cleaning

Standard pricing:

• Booked within 48 hours: $150/hour
• Scheduled next week: $150/hour (same rate, no rush fee)
• Off-peak season (winter): Sometimes 10% discount on labour

Pro tip: If it’s not an emergency, book for mid-week (Tuesday–Thursday). We’re less busy and can often fit you in faster.

DIY vs. Professional AC Repairs: What Can You Safely Do Yourself?

Some AC maintenance tasks are safe for homeowners. Others require a licensed technician. Here’s the breakdown:

Safe DIY Tasks (No Licence Required)

• Cleaning filters — rinse with water, let dry, reinstall. Cost: $0. Time: 10 minutes.
• Wiping down indoor unit — damp cloth on exterior and vents. Cost: $0. Time: 15 minutes.
• Clearing debris from outdoor unit — remove leaves, dirt, plants. Cost: $0. Time: 20 minutes.
• Checking circuit breaker — reset if tripped. Cost: $0. Time: 2 minutes. Learn how in our circuit breaker reset guide.
• Replacing remote batteries — obvious but often overlooked. Cost: $5. Time: 1 minute.

Tasks That Require a Licensed Technician

• Refrigerant handling — illegal without ARCtick licence. Cost: $250–$500.
• Electrical repairs — circuit boards, wiring, isolator switches. Cost: $150–$600.
• Compressor replacement — requires refrigerant handling. Cost: $500–$1,500.
• Fan motor replacement — electrical work. Cost: $250–$500.
• Drain pipe repairs — if it involves disassembling the indoor unit. Cost: $150–$350.
• Gas leak detection and repair — specialised equipment required. Cost: $250–$500.

Why it matters: DIY electrical or refrigerant work is illegal in Queensland, voids your warranty, and can be dangerous. We’ve seen homeowners cause $2,000+ in damage trying to save $150 on a repair.

When in doubt, call us. We’ll tell you over the phone if it’s something you can handle yourself.

Warranty Considerations: What’s Covered and What Voids It?

Most air conditioners come with a manufacturer’s warranty. Here’s what you need to know:

Standard Warranty Coverage

• Compressor: 5–10 years (most brands)
• Parts: 1–5 years
• Labour: 1 year (sometimes 2)

What’s Typically Covered

• Manufacturing defects
• Compressor failure (within warranty period)
• Electrical component failures

What Voids Your Warranty

• No proof of regular servicing — most brands require annual servicing by a licensed tech
• DIY repairs — especially electrical or refrigerant work
• Using unlicensed technicians — always ask for their ARCtick and electrical licence numbers
• Ignoring obvious problems — if you keep running a unit that’s making strange noises, you void the warranty
• Incorrect installation — if the original install wasn’t by a licensed tech, the warranty is void from day one

Pro tip: Keep all your service receipts. If you need to claim a warranty, the first thing they’ll ask for is proof of regular maintenance.

Seasonal Pricing Variations: When to Book AC Repairs in Brisbane

AC repair demand in Brisbane follows the weather. Here’s how it affects pricing and availability:

Peak Season (October–March)

• Highest demand: December–February (summer)
• Wait times: 2–5 days for non-emergency repairs
• Pricing: Standard rates, no discounts
• Tip: Book early in the morning for same-day service

Shoulder Season (April, September)

• Moderate demand: Still warm but not peak
• Wait times: 1–3 days
• Pricing: Standard rates
• Tip: Good time for preventative servicing

Off-Peak Season (May–August)

• Lowest demand: Winter (even though we still use AC for heating)
• Wait times: Same-day or next-day
• Pricing: Sometimes 10% discount on labour (ask when booking)
• Tip: Best time for major repairs or replacements

Pro tip: If your AC needs a major repair (compressor, PCB) and it’s not urgent, wait for winter. You’ll get faster service and possibly a discount.

Cost Breakdown by AC Type: Split System vs. Ducted vs. Multi-Head

Repair costs vary by system type. Here’s what to expect:

Split System Repairs

• Most common: Single indoor + outdoor unit
• Typical repair cost: $150–$600
• Pros: Simpler system, cheaper to repair, parts widely available
• Cons: One unit controls one room

Ducted System Repairs

• More complex: Central unit + ductwork + multiple vents
• Typical repair cost: $200–$800
• Pros: Whole-house cooling, hidden system
• Cons: More expensive to repair, ductwork issues add cost
• Common issues: Leaky ducts, zone control failures, central unit problems

Multi-Head Split System Repairs

• Multiple indoor units: One outdoor unit powers 2–5 indoor units
• Typical repair cost: $150–$700
• Pros: Zoned cooling, more efficient than multiple split systems
• Cons: If outdoor unit fails, all indoor units stop working
• Common issues: Refrigerant leaks in connecting pipes, communication errors between units

Which system do you have? Check your indoor unit. If there’s only one, it’s a split system. If you have vents in multiple rooms connected to ducts, it’s ducted. If you have multiple indoor units but only one outdoor unit, it’s multi-head.

Hidden Costs to Watch For: What’s Not Included in the Quote

Some AC repair quotes don’t include everything. Here’s what to ask about:

Diagnostic Fees

• Some companies charge: $80–$150 just to diagnose the problem
• Amplus Electrical & Air: No separate diagnostic fee — diagnosis is included in the repair cost

Travel Fees

• Some companies charge: $50–$100 for travel, especially to outer suburbs
• Amplus Electrical & Air: No call-out fee — we don’t charge for travel

After-Hours Charges

• Standard after-hours: 1.5x–2x the normal rate
• Amplus Electrical & Air: $180/hour after-hours (1.5x), no extra call-out fee

Parts Markup

• Some companies: Mark up parts by 50–100%
• Amplus Electrical & Air: Standard industry markup (20–30%), transparent pricing

Permits or Compliance Fees

• Rare for repairs: Usually only needed for new installations
• Exception: If your repair involves electrical work that requires a compliance certificate

Pro tip: Always ask for a detailed quote that breaks down labour, parts, and any additional fees. If a company is vague about pricing, get a second opinion.

Brisbane-Specific AC Problems: What Our Climate Does to Your System

Brisbane’s subtropical climate is tough on air conditioners. Here are the most common local issues:

1. Humidity and Mould Growth

The problem: Brisbane’s humidity (often 70–80% in summer) causes mould and mildew to grow rapidly in indoor units and drain pipes.

The fix: Regular cleaning (every 3 months) and anti-mould treatments. Cost: $150–$300.

2. Salt Air Corrosion (Bayside Suburbs)

The problem: If you live near the coast (Cleveland, Victoria Point, Wynnum), salt air corrodes outdoor units faster.

The fix: Rinse outdoor unit with fresh water every 3 months. Consider a marine-grade coating for new installations. Cost: $200–$400 for coating.

3. Storm Damage and Power Surges

The problem: Brisbane’s summer storms cause power surges that fry circuit boards and electrical components.

The fix: Install a surge protector ($150–$300). If damage occurs, replace the circuit board ($300–$600).

4. Extreme Heat and Overworking

The problem: When it’s 35°C+ outside, AC units work harder and overheat. This causes compressor stress and premature failure.

The fix: Regular servicing to ensure the unit is running efficiently. Don’t set the temperature too low (24–26°C is fine). Cost: $150–$250 for servicing.

5. Dust and Pollen (Spring)

The problem: Brisbane’s spring (September–November) brings high pollen and dust levels, which clog filters and coils.

The fix: Clean filters every 2–4 weeks during spring. Cost: $0 (DIY) or $150–$250 for professional cleaning.

Local insight: If you live in the Redlands or Bayside, your AC faces salt air, humidity, and storms. Regular maintenance isn’t optional — it’s essential. We see 30% more repairs in coastal suburbs compared to inland areas.

Repair vs. Replace: When Is It Time for a New AC?

Here’s a simple guide to help you decide. If you’re considering replacement, compare your options in our split system vs ducted air conditioning guide.

Repair When:

• The unit is less than 10 years old
• The repair cost is less than 50% of a new unit
• It’s a simple fix (filters, drain pipe, isolator switch)
• The unit is still energy efficient (star rating of 4+)

Replace When:

• The unit is more than 15 years old
• The repair cost is more than 50% of a new unit
• It needs a compressor replacement
• It’s using R22 refrigerant (being phased out, expensive to regas)
• It’s costing more than $400/year in repairs
• It’s not energy efficient (star rating below 3)

Real Examples: AC Repairs We’ve Done in the Redlands

Example 1: AC Not Cooling in Capalaba

The problem: Customer’s 5-year-old split system was running but not cooling properly. The room temperature stayed at 28°C even when set to 22°C.

What we found: The filters were completely blocked with dust and the outdoor coils were clogged with dirt and leaves. The unit was working hard but couldn’t exchange heat properly.

The fix: We deep-cleaned the filters and outdoor coils. We also checked the refrigerant levels — they were fine.

The cost:

• Labour: 1.5 hours @ $150/hour = $225
• Total: $225

Example 2: AC Leaking Water in Cleveland

The problem: Customer’s split system was leaking water onto the floor from the indoor unit.

What we found: The drain pipe was blocked with mould and algae. Water was backing up in the drain tray and overflowing into the room.

The fix: We cleared the blocked drain pipe, flushed the system with an anti-mould treatment, and checked the drain tray for cracks.

The cost:

• Labour: 1 hour @ $150/hour = $150
• Anti-mould treatment: $35
• Total: $185

Example 3: Refrigerant Leak in Alexandra Hills

The problem: Customer’s 8-year-old split system was slowly losing cooling power. They’d had it regassed 6 months ago but the problem came back.

What we found: A small corroded spot on the outdoor coil was causing a slow refrigerant leak.

The fix: We repaired the corroded spot, vacuumed the system, and regassed it with the correct amount of refrigerant. We pressure-tested the system to confirm the leak was fixed.

The cost:

• Labour: 2.5 hours @ $150/hour = $375
• Refrigerant: $120
• Total: $495

Example 4: AC Not Turning On in Thornlands

The problem: Customer pressed the power button on their remote and nothing happened. No lights, no sound, nothing.

What we found: The isolator switch next to the outdoor unit had failed. It wasn’t passing power to the unit.

The fix: We replaced the faulty isolator switch and tested the system.

The cost:

• Labour: 45 minutes @ $150/hour = $113
• New isolator switch: $65
• Total: $178

Example 5: Compressor Failure in Victoria Point

The problem: Customer’s 16-year-old split system was making a loud buzzing sound and not cooling. The outdoor unit was vibrating excessively.

What we found: The compressor had failed. It was drawing excessive current and making abnormal noises.

The assessment: A new compressor would cost $900–$1,200. The unit was 16 years old and using R22 refrigerant (expensive and being phased out). We recommended replacement instead of repair.

The outcome: Customer replaced the old unit with a new 5kW inverter split system for $2,800. The new unit is quieter, more efficient, and comes with a 5-year warranty.

How to Prevent Expensive AC Repairs

Most air conditioning problems can be prevented with regular maintenance:

1. Clean Filters Every 1–3 Months

Dirty filters are the #1 cause of AC problems. They restrict airflow, reduce efficiency, and can cause the unit to freeze up. Clean your filters every 1–3 months during summer.

2. Service Your AC Every 1–2 Years

A professional service includes cleaning the coils, checking refrigerant levels, inspecting electrical connections, and testing the system. Cost: $150–$250. This prevents most expensive repairs.

3. Keep the Outdoor Unit Clear

Make sure the outdoor unit has at least 30cm of clear space around it. Remove leaves, dirt, and debris regularly. Don’t let plants grow over the unit. For more efficiency tips, check out our guide on split system running costs in Brisbane.

4. Don’t Set the Temperature Too Low

Setting your AC to 18°C when it’s 35°C outside makes the unit work harder than necessary. Set it to 24–26°C for comfort and efficiency.

5. Use a Programmable Timer

Set your AC to turn on 30 minutes before you get home and turn off when you leave. This reduces wear and tear and saves on energy bills.

6. Address Small Problems Immediately

A $150 repair today can prevent a $600 repair next month. If your AC is making a strange noise, leaking slightly, or not cooling as well as it should, don’t ignore it. Small problems become big problems quickly in Brisbane’s climate.

7. Consider a Maintenance Plan

Some companies offer annual maintenance plans for $200–$400/year. These include 1–2 services per year, priority booking, and discounts on repairs. For most homeowners, paying per service ($150–$250 each) is cheaper than a maintenance plan. But if you want the peace of mind, it’s an option.
