Electrician Charges In Singapore | How To Avoid Overpaying

Handyman services

If you’re living in an HDB flat, condo, or landed property, you’ve needed electrical help at some point. Whether it’s faulty wiring, installing a new ceiling fan, or upgrading your lighting, hiring a licensed electrician in Singapore is essential.

But how much does it cost? And what exactly are you paying for? Let’s break it down.

1. Electrician Services in Singapore

Electricians are skilled professionals who handle everything from basic installations to complex rewiring jobs. Here’s a quick list of standard services:

  • Power socket installation and replacement
  • Light fixture installation
  • Ceiling fan setup
  • Switch and circuit breaker repair
  • Rewiring of old flats
  • Troubleshooting power failures
  • Installation of water heater or appliances
  • Electrical inspection for home renovation

Each job requires technical know-how and compliance with Singapore’s building and safety codes.

2. Average Cost of Electrician Services in Singapore

Electrician charges depend on the complexity of the job, materials used, and property type (HDB, condo, or landed).

Here’s a rough guide:

ServiceEstimated Cost (SGD)
Replace power socket $50–$90
Install ceiling fan $80–$150
Troubleshoot power trip$60–$120
Replace light fixture $40–$100
Switch installation$40–$80
Complete HDB rewiring (3-room)$2,500–$4,000
Full condo rewiring$3,000–$5,500

Note: Prices may vary depending on time of day (after-hours/emergency), material quality, and additional labour required.

3. Why Do Electricians Cost So Much?

Some homeowners are surprised by the cost of hiring an electrician. But here’s what you’re paying for:

  • Expertise & Certification: Only certified electricians are allowed to do electrical work in Singapore. They must be trained, tested, and licensed by EMA.
  • Safety & Compliance: Faulty installations can be dangerous. You’re paying for peace of mind.
  • Tools & Equipment: Quality tools and materials don’t come cheap.
  • Insurance & Warranty: Many reliable electricians offer warranties on their work and are insured in case of mishaps.

4. HDB vs Condo vs Landed Homes

Ever wondered if the cost between a HDB and Condo differ? Well, yes. Here’s why:

  • HDB Flats usually have standardised layouts, making jobs quicker.
  • Condos may require coordination with MCST or management before works can begin.
  • Landed Properties are larger and may involve more complex rewiring.

The more complicated the job, the higher the cost.

5. Emergency or After-Hours Electrician? Expect to Pay More

If your power trips in the middle of the night or you experience a blackout on a Sunday, you’ll need emergency services.

Emergency electrician callouts often cost 1.5 to 2 times more than regular appointments. This covers transport, overtime, and availability.

6. How to Know If You’re Being Overcharged

Here are a few ways to make sure you’re paying a fair price:

  • Get at least three quotes from different electricians.
  • Check their license and experience.
  • Look at Google reviews or testimonials.
  • Ask if the price includes materials, labour, and transport.

Transparent pricing is key. Watch out for hidden fees, such as “last-minute charges” or vague material costs.

7. Should You DIY or Always Call a Pro?

It’s tempting to install a new light switch yourself, but in Singapore, doing unauthorised electrical work is illegal and unsafe.

Only licensed electricians are permitted to undertake most electrical work, particularly tasks involving power sockets or circuit breakers.

For small tasks, such as changing a light bulb, go ahead. For anything else, call a pro.

8. Tips to Save Money on Electrical Work

  • Bundle services: Need to install multiple lights or switches? Get them done together for better rates.
  • Off-peak hours: Schedule work during weekdays instead of weekends or holidays.
  • Use your materials: If you have already bought a ceiling fan, pay for labour.

9. Finding a Reliable Electrician in Singapore

You can find reputable electricians via:

  • Online home services platforms (like StringsSG)
  • Neighbourhood contractors
  • Referrals from friends and family

Always choose someone licensed by EMA. If they can’t produce their license number, that’s a red flag.

10. Final Thoughts

Paying for a reputable electrician ensures safety, high-quality work, and fewer future problems. Think of it as an investment in your home.

Cutting corners with cheap or unlicensed electricians may lead to more expensive repairs, or worse, safety hazards.

Risk Of Cheap Aircon Servicing In Singapore | 7 Check Points

technician inspecting aircon before service

In Singapore, properly working aircon isn’t just a luxury; it’s a necessity. Whether you stay in an HDB flat, condo, or landed home, aircon units run almost daily to beat the island’s tropical heat. That means regular servicing is key to keeping your units in top shape.

But with so many companies offering cheap aircon servicing, it’s easy to get tempted by $18 or $20 promotions. Are these deals worth it, or could they cost you more in the long run?

Here are the top 7 ways to check if cheap aircon servicing is worth your money, and how to ensure you don’t fall for cut-price deals that compromise quality.

1. Understand What the Servicing Includes

Cheap prices often mean a stripped-down service. Before booking, always ask for clear details about what’s included.

A proper aircon servicing should cover:

  • Cleaning air filters and front panel
  • Flushing drainage pipes to prevent leaks
  • Checking cooling performance
  • Inspecting refrigerant levels
  • Basic inspection of fan coils and blower

If the cheap package only mentions filter cleaning, it’s probably not enough to keep your aircon running efficiently, especially with Singapore’s constant humidity.

2. Check the Company’s Reviews

Always Google the company or check platforms like Facebook, Carousell, or even forums like HardwareZone.

Look out for:

  • Consistent positive reviews from real Singapore customers
  • Mentions of punctuality and professionalism
  • Photos showing the servicing process
  • Caution if you see multiple complaints about rushed jobs or hidden charges

A company with a strong reputation is less likely to cut corners, even if they offer affordable rates.

3. Are the Technicians Certified?

Singapore has no strict licensing requirement for basic aircon servicing, but reputable companies often employ technicians certified by:

  • National Environment Agency (NEA)
  • Building and Construction Authority (BCA)
  • Brand certifications (Daikin, Mitsubishi, etc.)

Qualified technicians know how to service different aircon models safely, ensuring better results. If a company can’t tell you their technicians’ qualifications, that’s a red flag.

4. Beware of Hidden Charges

Low upfront prices often come with sneaky upselling tactics. Some common scenarios:

  • They quote $20 for servicing, then recommend a costly chemical wash without a clear explanation
  • They add “transport” or “inspection” fees after arriving
  • They push for gas top-ups even if unnecessary

Always request a clear, itemised price breakdown before confirming the appointment. Legitimate companies will be upfront about all costs.

5. Service Warranty Provided?

Professional aircon companies usually provide a short service warranty — ranging from 30 to 90 days — covering artistry and immediate issues like minor leaks or unusual noises.

No warranty? That’s a sign the company isn’t confident in the quality of its work.

6. How Long Does the Job Take?

A rushed job often means poor service. For standard aircon servicing, technicians typically spend:

⏱️ 15 to 20 minutes per unit for proper cleaning

⏱️ Longer if they check the refrigerant, drainage pipes, and test the cooling system

If your technician finishes in under 10 minutes per unit and doesn’t test the aircon after, chances are they skipped essential steps.

7. Are You Getting a Service Report?

After servicing, reliable companies provide a summary of:

  • What was cleaned
  • Cooling performance after servicing
  • Any issues found and suggested repairs

If the technician packs up and leaves without explanation, you probably didn’t get proper servicing, no matter how low the price.

The Risks of Low-Quality Aircon Servicing

Going for the cheapest option without proper checks may lead to:

  • Reduced cooling efficiency
  • Higher electricity bills
  • Persistent water leaks
  • Unpleasant smells or poor air quality
  • Aircon breakdowns requiring costly repairs

In the long run, a $20 deal can easily turn into a $200 problem.

How Much Should Aircon Servicing Cost in Singapore?

As of 2025, here are the average market rates:

Service TypeEstimated Price (Per Unit)
General Servicing $25 – $40
Chemical Wash$70 – $120
Chemical Overhaul$140 – $170
Gas Top-up$80 – $150

Many companies offer discounts for multiple units, which is common for HDBs and condos with 3 to 5 aircon units.

When Is It Okay to Go Cheap?

If:

  • You only need very basic filter cleaning
  • You’ve done recent deep cleaning (chemical wash)
  • The company is reputable and transparent about pricing

A cheaper servicing package can be worth it for quick maintenance, but if your aircon is leaking, noisy, smells bad, or isn’t cold, basic servicing won’t fix the problem. You’ll still need more thorough work.

Final Thoughts

In Singapore, aircon servicing is crucial for comfort and efficiency. Cheap aircon servicing can be worth it if:

  • It comes from a reliable company
  • The service is clearly defined
  • You only need light, routine maintenance

But don’t blindly go for the lowest price. Check reviews, ask questions, and look for signs of professionalism.

Remember, a slightly higher price upfront often saves you from costly repairs, higher electricity bills, or an unexpected aircon breakdown later.

Regular Aircon Servicing Is Important For Every Home

aircon is noisy

In Singapore’s hot and humid climate, having a working aircon isn’t a luxury, it’s a necessity. Whether you live in an HDB flat, a condo, or a landed property, chances are your aircon is working overtime to keep you cool. But many homeowners overlook one crucial thing: regular aircon servicing.

Think of your aircon like your car. You wouldn’t drive it endlessly without servicing it, right? The same logic applies. Regular aircon servicing keeps your unit running efficiently, helps you save money, improves indoor air quality, and prevents costly breakdowns.

Here’s everything you need to know about why aircon servicing in Singapore is so important, how to monitor your aircon for problems, and when to call the experts.

Why Aircon Servicing Is So Important for Singapore Homes

1. Saves You Money in the Long Run

A well-maintained aircon doesn’t have to work as hard to cool your space. This means lower electricity bills, which is especially helpful with Singapore’s rising energy costs. If your aircon is clogged with dust or its components are worn out, it draws more power to produce the same amount of cooling, which shows up in your monthly bill.

2. Keeps Your Aircon Running Efficiently

Regular aircon cleaning ensures filters, coils, and other components are cleaned and functioning well. When everything works as it should, your aircon cools your home faster and more efficiently, even during the peak afternoon heat.

3. Prevents Unexpected Breakdowns

A breakdown during Singapore’s sweltering months is every homeowner’s nightmare. Routine servicing helps catch small issues like refrigerant leaks, clogged filters, or worn-out parts before they snowball into bigger, more expensive problems.

4. Improves Indoor Air Quality

Dirty air filters and components can harbour dust, bacteria, and mold (not ideal for your family’s health). This is especially important in Singapore, where many homes are closed up with little natural ventilation. Regular servicing helps your aircon circulate clean, fresh air.

5. Prolongs the Lifespan of Your Aircon

Aircons aren’t cheap, and replacing them is a significant expense. Regular servicing ensures your unit lasts as long as possible, giving you better value for your investment.

How to Monitor Your Aircon for Potential Problems

Even with regular professional servicing, keeping an eye (and ear) on your aircon is good. Here are common warning signs to look out for:

1. Weak Cooling

If your aircon doesn’t cool your space as effectively as it used to, it could indicate clogged filters, low refrigerant levels, or a mechanical fault.

2. Strange Noises

Unusual sounds like banging, hissing, or grinding are red flags. These noises could point to loose parts, debris build-up, or refrigerant leaks that require professional attention.

3. Water Leaks

If you notice water pooling below your aircon or dripping from the unit, there may be a blocked drainpipe or a full drainage tray.

4. Bad Odours

A musty or foul smell coming from your aircon is a tell-tale sign of mold or bacteria growing inside the system — not something you want circulating in your home.

5. Higher Electricity Bills

A sudden spike in your utility bill, without any increase in usage, often signals your aircon is working inefficiently. Which means, it’s only time to book that servicing appointment!

aircon tech

How Often Should You Service Your Aircon in Singapore?

The frequency depends on how often you use your aircon and where you live:

UsageRecommended Servicing
Light Use (e.g., 1-2 times a week)Every 6 months
Moderate Use (e.g., daily, nights only) Every 3-4 months
Heavy Use (e.g., daily, day & night)Every 2-3 months
Commercial or Office AirconsMonthly or based on technician advice

Most households benefit from servicing HDB flats or condo units every 3-4 months, especially if the aircon runs nightly. If you have multiple units or live in a landed property, coordinate servicing for all units to optimise efficiency.

When to Call a Professional Aircon Technician

While basic maintenance like cleaning filters can be done yourself, certain tasks require an expert’s touch:

  • Strange noises or smells from the unit.
  • Persistent water leaks.
  • Weak or no cooling despite correct settings.
  • Regular servicing is overdue.
  • You suspect a refrigerant leak.

Tip: Avoid DIY repairs for complex aircon problems. Tampering with electrical components or refrigerant can be dangerous and may void your warranty.

What Happens During a Professional Aircon Servicing?

A typical servicing session includes:

✔️ Cleaning of air filters, front panel, and cover.

✔️ Vacuuming of drainage system to prevent leaks.

✔️ Checking fan motor, blower, and electrical connections.

✔️ Inspecting refrigerant levels and cooling performance.

✔️ Testing the aircon to ensure everything runs smoothly.

Consider a chemical wash or overhaul for more thorough maintenance, especially for older or heavily-used units.

Final Thoughts

Your aircon works hard to keep your home cool and comfortable, so it deserves some TLC in return. Regular servicing keeps your cooling system running efficiently, protects your family’s health, reduces electricity costs, and prevents inconvenient breakdowns.

Living in Singapore’s tropical climate means your aircon is likely running daily. Don’t wait until there’s a problem… book regular servicing and enjoy peace of mind all year round!

Which Is The Best Electricity And Gas Plans For Your Home?

image of gas

Managing household utilities in Singapore has become more flexible in recent years, thanks to the Open Electricity Market (OEM) and various gas providers offering customised plans. Whether living in an HDB flat, a condominium, or a landed property, selecting the right electricity and gas plan can help reduce your monthly utility bills while ensuring a reliable supply of essential services.

With so many options on the market, feeling overwhelmed is natural. In this guide, we explain how electricity and gas plans work in Singapore and share practical tips to help you choose the best plan for your home.

Before 2018, Singapore households had no choice but to buy electricity from SP Group, the national utility provider. However, with the introduction of the Open Electricity Market (OEM), residents can now choose from several electricity retailers offering different rates and packages.

Types of Electricity Price Plans

There are two main types of electricity plans available for households:

1. Fixed Price Plan

This plan offers a constant rate for electricity (per kWh) throughout the contract period, regardless of market fluctuations.

Who Should Consider This:

  • Those who prefer certainty in their monthly bills.
  • Homeowners who dislike dealing with price fluctuations.
  • Households with consistent electricity usage.

2. Discount Off Regulated Tariff (DOT) Plan

This plan provides a fixed percentage discount off the regulated tariff set by SP Group. The tariff may fluctuate every quarter, but you enjoy guaranteed savings at that rate.

Who Should Consider This:

  • Residents comfortable with variable bills.
  • Those who prefer following SP’s tariff trends but want to pay less.

Top Electricity Retailers in Singapore (2025)

Here’s a quick look at some of the most popular electricity retailers serving Singaporean households:

RetailerPlan Highlights
GenecoCompetitive fixed price, DOT plans, and eco-friendly options
Keppel ElectricReliable service with stable fixed prices
Senoko EnergyAttractive rebates and flexible payment options
Tuas PowerBudget-friendly rates regular promotions
Sembcorp PowerOffers both fixed and discounted tariff plans

Note: Plans and rates are subject to change. Always check the latest offerings before committing.

Things to Consider When Choosing an Electricity Plan

1. Contract Duration

Most plans come with 12, 24, or 36-month contracts. Shorter contracts offer more flexibility, while more extended contracts may provide better rates.

2. Early Termination Fees

Exiting a contract before it ends usually incurs penalties. Read the terms carefully before signing.

3. Rebates and Promotions

Retailers often run promotions, offering bill rebates, free months, or vouchers. Factor these into your decision, but prioritise the long-term cost.

4. Green Energy Options

If you’re environmentally conscious, some retailers offer carbon-neutral or solar energy plans for a greener home.

For most HDB and condo residents, town gas is the preferred and most convenient option. LPG remains popular in landed homes, especially where piped gas is unavailable.

How to Manage and Save on Gas Bills

  • Use energy-efficient appliances with a 3-tick or 4-tick rating.
  • Check for gas leaks regularly and ensure proper maintenance.
  • Don’t leave gas stoves running unattended.
  • For LPG users, buy from authorised suppliers to ensure safety and fair pricing.

Which Plan Combination Is Best for Your Home?

Choosing the best electricity and gas plan depends on your lifestyle, property type, and consumption patterns.

For HDB Residents

  • Consider a fixed-price electricity plan for stability.
  • Stick with City Energy’s piped gas for hassle-free supply.
  • Opt for LED lights and inverter aircon units to save energy.

For Condo Owners

  • Check if your condo has a centralised energy management system.
  • If eligible, compare OEM retailers for electricity savings.
  • Use piped gas if available; otherwise, LPG may be required.

For Landed Property Owners

  • You likely use LPG for gas supply.
  • Consider larger capacity, energy-efficient appliances to manage overall consumption.
  • Electricity retailers often offer bulk discounts for high-usage households.

Final Tips Before You Sign Up

  • Compare retailers regularly using platforms like OEM’s Compare Tool.
  • Watch out for hidden fees or administrative charges.
  • Read reviews to ensure the retailer provides good customer support.
  • For gas services, always engage licensed gas service workers for installation and maintenance.

Final Thoughts

With the variety of electricity and gas plans now available in Singapore, homeowners have more power to manage their utility bills. Whether you live in an HDB flat, a condo, or a landed house, choosing the right plan can lead to significant cost savings in the long run.

By understanding your household’s energy needs and comparing available options, you can enjoy peace of mind knowing you’re getting the best value without compromising comfort or safety.

7 Expert Tips To Prevent Your Aircon From Overheating

aircon chemical was by a professional technician

In Singapore’s sweltering heat, your aircon is more than just a luxury; it’s a daily essential. But constant use and poor maintenance can cause your aircon to overheat. When that happens, it can result in poor cooling performance, higher energy bills, expensive repairs, or a complete system breakdown.

If you want to keep your home cool and your aircon running efficiently, prevention is key. In this guide, we share with you the top seven practical tips to help prevent your aircon from overheating and ensure it performs at its best for years.

1. Clean or Replace Air Filters Regularly

Clogged air filters are one of the most common causes of aircon overheating. In Singapore’s humid climate, dust and dirt build up quickly. When the filters are blocked, airflow is restricted, forcing the aircon to work harder to circulate cool air.

Check your air filters at least once a month. If they appear dirty, clean them under running water and let them dry completely before reinstalling. Consider replacing filters every few months for homes with pets, smokers, or frequent aircon use.

2. Keep the Outdoor Unit Clean and Unobstructed

Your aircon’s outdoor condenser unit is crucial in releasing heat from the system. If the condenser coils are covered with dust, leaves, or other debris, heat cannot escape efficiently, causing your aircon to overheat.

It’s crucial to,

  • Inspect the outdoor unit regularly.
  • Clear away leaves, dust, and any debris.
  • Maintain at least one metre of clearance around the unit for proper ventilation.

In Singapore’s high-rise apartments, where space is tight, ensure balcony plants, laundry racks, or furniture don’t block the airflow.

3. Schedule Regular Professional Servicing

Even with DIY cleaning, there are areas of your aircon you can’t easily access. Over time, dirt builds up inside components like the evaporator coils and fan motor, contributing to overheating.

Book professional aircon servicing at least once every 6 months. During servicing, the technician will clean internal components, check for signs of wear, and ensure your aircon is running optimally.

4. Consider a Chemical Wash for Deep Cleaning

If regular servicing isn’t enough, a chemical wash can help remove stubborn dirt, bacteria, and mold that build up deep inside your aircon.

When the system is clogged, airflow is restricted, forcing the motor and compressor to work harder, leading it to overheat.

Arrange for a chemical wash every 12 to 18 months, especially for older units or those not serviced regularly. It’s a deep cleaning process where components are dismantled and thoroughly cleaned with specialised solutions to restore cooling efficiency.

5. Maintain Proper Ventilation Around Your Aircon

Indoor and outdoor units need adequate ventilation for your aircon to cool efficiently. Poor ventilation can trap heat inside the system, causing it to overheat.

These could help:

  • Keep curtains or blinds closed during peak sunlight to reduce the room’s heat load.
  • Ensure the aircon’s vents and grilles are not blocked by furniture or large objects.
  • Avoid placing the outdoor unit in a confined or poorly ventilated space.

Good ventilation means your aircon doesn’t have to work overtime to keep your space cool.

6. Monitor for Early Warning Signs

Overheating rarely happens suddenly. Your aircon often gives warning signs before serious damage occurs. The key is to recognise these signs early and act before it worsens.

Look out for these overheating indicators:

✔️ Warm air blowing from the vents.

✔️ Frequent system shutdowns.

✔️ The outdoor unit feels excessively hot.

✔️ A buzzing or humming sound from the compressor.

✔️ Unusual spikes in your electricity bill.

If you notice any of these, switch off your aircon immediately and call a professional for inspection.

7. Don’t Overwork Your Aircon

Running your aircon non-stop or setting the temperature to the lowest possible setting may seem like a good way to beat the heat—but it puts immense strain on the system. This constant strain leads to overheating, higher energy consumption, and faster wear and tear.

You can,

  • Set your aircon to an energy-efficient temperature of around 24-25°C.
  • Use a fan alongside your aircon to help circulate cool air.
  • Turn off your aircon when you leave the room.
  • Give the system short breaks throughout the day to prevent overuse.

If your aircon is too small for your space, it will sometimes struggle to cool effectively, leading to overheating. Speak to a technician to ensure your aircon is correctly sized for your room.

Bonus Tip: Upgrade When Necessary

Older aircon units overheat more frequently due to worn-out components and outdated technology. Consider an upgrade if your aircon is over 10 years old and constantly overheating despite maintenance.

Modern aircons are designed to be more energy-efficient, quieter, and better equipped to handle Singapore’s tropical climate without overworking.

Final Thoughts

Preventing aircon overheating isn’t just about keeping your home cool, it also saves you money, extends the lifespan of your system, and prevents unnecessary breakdowns.

By following these seven tips — cleaning filters, maintaining the outdoor unit, scheduling regular servicing, opting for chemical washes, ensuring proper ventilation, spotting warning signs, and avoiding overuse — you can enjoy efficient, reliable cooling all year round.

If your aircon still shows signs of overheating despite your efforts, don’t delay. Call a trusted aircon technician in Singapore to diagnose the issue and get your cooling system back on track.
