Hire The 11 Best Aircon Servicing Companies In Singapore In 2025

Singapore’s humid and tropical climate creates a heavy reliance on air conditioners. With such heavy usage and reliance, aircons need to be serviced regularly to ensure efficient cooling and prevent expensive breakdowns. Regular aircon servicing in Singapore is essential for efficiency, cost savings, better air quality, and preventing major breakdowns. In this article, we cover the top aircon servicing companies in Singapore in 2025, their prices and reviews, and the importance of choosing a professional aircon servicing company in Singapore. We will also discuss some of the common aircon problems that require servicing, go over aircon maintenance tips, and answer common queries regarding aircon servicing.

When Do You Need Aircon Maintenance?

Due to Singapore’s warm climate, most people use their air conditioning units daily. Given this high frequency of usage, it is safe to say that air conditioning servicing should be carried out at least 2-4 times a year.

Several factors affect how often you should service your aircon in Singapore. These factors include:

• How often do you use your aircon unit? Is it daily?
• Is it for commercial use or residential use? Commercial aircon tend to be used at a higher rate and may need servicing more frequently than residential ones.
• Is the room/unit facing a leading road or a construction site? If so, you may want to consider that the air conditioning unit will endure a significant dirt intake.

Consider the factors above and decide how frequently your aircon needs servicing. The recommended number is four times a year (once per quarter), and the bare minimum is two.

 

When Should You Engage Aircon Servicing in Singapore?

Aircon servicing in Singapore is quintessential for maintaining every HDB, condo, or office. While it maintains cooling systems’ efficiency, it ensures owners save energy and breathe clean air in the ever-humid climate. 

Typically, there is no best in the field, as every company has its own niche of expertise. Moreover, you should not assume a professional is better just because they work with a particular aircon brand. What’s most important is knowing when to service your unit and avoid costly issues. Below are five triggers for hiring BCA-trained pros for aircon servicing Singapore in 2025, with tips to maximise unit performance:

• Routine Maintenance (Every 3–6 Months): Service HDB units quarterly for heavy use or biannually for light use to prevent dust buildup (SGD 35–150/unit). According to aircon brand experts, Panasonic and Mitsubishi Electric units benefit from regular checks.

• Poor Cooling or High Bills: Warm air or 5–15% bill spikes signal clogs or low refrigerant. A chemical wash (SGD 80–250/unit) or gas top-up (SGD 50–200) by Coolman restores efficiency.

• Noises, Odours, or Leaks: Rattling, musty smells, or water leaks indicate mould or loose parts. Servicing (SGD 35–150/unit) by LK Brothers fixes HDB units fast, per top aircon brands in Singapore.

• Before Peak Seasons: Service before summer (March–June) to handle Singapore’s heat, ensuring Samsung or other units perform optimally. Book early with Harvey Norman pros (SGD 35–150/unit).

• Anti-Allergen Needs: For allergies, service units with Panasonic’s nanoe™ or Mitsubishi Electric’s filters via Courts (SGD 80–250/unit) to remove mould and bacteria.

Types of Aircon Servicing in Singapore for 2025

Undoubtedly, regular aircon servicing is the only way to keep your HDB, condo, or office cool in Singapore’s forever-humid climate. Luckily, top providers like Gain City, SoCool, and LK Brothers offer tailored services to maintain performance and air quality. Below are some of the most common types of aircon servicing with 2025 price estimates:

General Aircon Servicing (SGD 35–150/unit)

General aircon servicing is the most common type of aircon service, typically offered by all BCA-compliant pros. It encompasses a standard cleaning of the filters, fan coils, drain pipes, panels, and checking for minor issues. Still, it’s a must-have if you want to boost and maintain an optimal efficiency of your unit. 

Typically, pros recommend scheduling such a check-up every 3-4 months for HDB daily use or 6 months for lighter use. Many companies offer package check-ups with discounts lower bills and guaranteed dust and allergen-free air.

Aircon Chemical Wash (SGD 80–250/unit)

Unlike general aircon servicing, aircon chemical wash involves a much thorough, deeper cleaning. This procedure is typically suitable for neglected units or ones with performance problems left unresolved by general servicing. 

In most cases, professional aircon companies in Singapore dismantle the units in question and deep clean the coils, blowers, and pipes. They use special chemical solutions that dissolve heavy dirt, odours, and mould. If you haven’t serviced your unit in a while or it underperforms, companies like SoCool and Coolman can restore its old-time performance.

Aircon Chemical Overhaul (SGD 150–450/unit)

If you’ve used your central or split HDB aircon for more than five years, then it most likely requires more than a simple cleaning. An aircon chemical overhaul goes even deeper than chemical washes, as it tackles heavily clogged and even malfunctioning units (e.g. leaks, noises). 

Despite its considerably higher price, this service helps address more complex issues and extend the life of older units. Vetted professionals like LK Brothers offer overhauls at reasonable prices, which can bring your old split system back to life.

Aircon Gas Top-Up (SGD 50–200)

Aircon gas top-up services are common for Singapore’s humid climate. Since most cooling systems work nonstop, they often suffer from extensive wear and tear. The constant strain on the system unit often results in refrigerant leaks, which reduce the cooling efficiency. 

Fortunately, calling a vetted air conditioning servicing company can address the warm air and cycling issues. The procedure takes 30-60 minutes and involves a leak check-up and gas top-up. However, keep in mind that HDBs with false ceilings may require more time and potentially increase the service cost.

Aircon Maintenance Contracts (SGD 100–600/year)

Many Singapore aircon service providers offer general cooling system service package deals. Typically, they involve scheduling check-ups from vetted pros for a set period (e.g. quarterly or bi-annual). While it may cost more upfront, scheduled maintenance dramatically lowers the total cost of taking care of multiple units. For example, some companies like DW Aircon and Coolman may waive transport fees. Best of all, an aircon maintenance contract guarantees priority repairs and emergency support, which will ensure your HDB aircon is in optimal condition.

Why Is Aircon Servicing Important in Singapore for 2025?

Regular aircon servicing is a must-have in Singapore’s climate, where dust, mould, and humidity constantly strain cooling systems. Failing to keep your HDB, condo, or office units clean often leads to increased bills, health harm and risk of aircon breakdowns. Professional servicing by companies like Gain City or LK Brothers prevents these issues, saving costs and ensuring comfort. Here’s a full breakdown on the importance of keeping your aircon well-maintained in 2025:

• Prevents Efficiency Loss: Dust and mould clog filters and coils, cutting airflow by 5–20% and raising bills by 10–15%. General servicing cleans components, restoring HDB unit efficiency and saving energy. 
• Protects Components: Pollutants strain compressors and fans, risking wear or failure over 5–10 years. Servicing (SGD 35–150/unit) by SoCool prevents costly repairs (SGD 50–450), extending unit life to 15 years.
• Improves Air Quality: Mould and bacteria in HDB units cause odours and allergies, which are often amplified by humidity. Chemical washing (SGD 80–250/unit) by Coolman removes contaminants, ensuring clean air.
• Avoids Breakdowns: Unserviced units face aircon leakages, noises, or shutdowns due to clogged drains or low refrigerant, which often require complex solutions by experts like Gain City.
• Meets HDB Guidelines: HDB requires BCA-trained technicians to maintain the external wall face and comply with the general building guidelines. 

Hiring a vetted air conditioning company can help you install window solar films. These films protect your unit by absorbing heat and harmful UV rays and significantly improve its efficiency.

Benefits of Aircon Servicing

The benefits of regular aircon servicing are numerous, including:

• Water leaking rectification (by vacuuming) during the contract period
• Minimise the aircon system breakdown
• Preventive measures against possible wear and tear, as well as subsequent problems
• Cost savings, such as waiver of transportation charges throughout the contract period
• Cost savings in terms of aircon efficiency and durability
• Saving on total maintenance cost (for chemical overhaul)
• Healthier, cleaner air quality
• Improve cooling efficiency
• Entitlement to a discount for ad-hoc repair work (for some companies)

Eventually, these lead to the most crucial benefit: prolonging the air-conditioners’ lifespan and saving you more money. 

HDB Guidelines Regarding Aircon Servicing

If you are looking for aircon servicing in Singapore, read up on the guidelines set by HDB. Some of the essential pointers include:

• You must maintain the external wall face free from stains at all times, at your own expense
• perform regular maintenance on your aircon to avoid causing any inconvenience or nuisance to your neighbours
• You should address any problem when it arises. If this criterion is not met, HDB will ask you to stop using or to remove the aircon

Common Aircon Issues Requiring Servicing in Singapore for 2025

Regardless of their brand, efficiency level, or durability, air conditioners are extremely susceptible to wear and tear in Singapore’s humid climate. The most visible result of such negligence and lack of regular servicing is bill spikes and disrupted HDB, condo, or office cooling. However, unserviced air conditioners can cause many health issues like allergies, asthma, and other respiratory conditions. 

Below are five common issues, their causes, and how professional servicing fixes them, with 2025 costs. 

• Increased Power Consumption: Dirty filters block airflow, forcing HDB aircons to overwork, raising electricity bills by 5–15%. Dust and allergens from Singapore’s humidity clog filters fast, straining compressors. General servicing by DW Aircon cleans filters and restores efficiency, saving up to 20% on energy costs.

• Component Wear: Dust and clogs stress compressors or fans, causing wear or failure over the years, especially in heavily used HDB units. This increases repair costs, often requiring a complete overhaul. On the contrary, general servicing by companies like SoCool prevents damage, extending unit life to 5–15 years.

• Dirty Condenser Coil: Outdoor coil buildup, worsened by Singapore’s dust, cuts heat transfer by 10–20%, reducing cooling and risking overheating. Chemical washing clears residue, ensuring HDB units cool effectively. Scheduling annual check-ups will add peace of mind and minimise the risk of breakdowns.

• Poor Air Quality: Mould and bacteria in filters thrive in humid HDB flats, causing odours and triggering allergies or asthma. Chemical washing removes mould, improving air quality and preventing health issues.

• Unusual Noises or Smells: Rattling (loose screws, debris) or musty odors (mold, clogs) signal faults in HDB air conditioners. A one-time aircon servicing by Homees’ vetted pros fixes loose parts and cleans drains, restoring quiet, fresh operation.

 Ad-hoc Aircon Servicing/Maintenance Price (One-Time)

The price depends on the number of units cleaned and how deep the aircon cleaning maintenance is. Aircon cleaning services can be engaged on a one-time cleaning or a scheduled, contracted maintenance basis.

In general, prices of servicing in Singapore range between:

• Type of aircon: The more powerful the aircon, the more costly it will be to service. Aircon servicing usually goes by the number of coils, hence it may affect your cost.
• Odd hours: Should the servicing be an emergency and require an urgent service, aircon contractors will usually charge you extra for that.

Servicing Basics

Understand when and why to service your aircon.

How often should I service my aircon unit?

What are the signs that my aircon needs servicing?

Poor cooling, unusual noises, water leaks, foul smells, or high electricity bills are a few of the signs that your air conditioner needs servicing. These typically signal issues like clogged filters or low refrigerant, which require a check-up from reputable companies for professional HDB-compliant servicing to restore performance.

What happens if I don’t service my aircon regularly?

Skipping regular aircon servicing in Singapore reduces cooling efficiency, raises energy costs, and causes leaks or breakdowns. Over time, costly repairs or unit replacement may be needed. Schedule quarterly checks with Homees’ pros to keep HDB or condo units in top shape.

How much does aircon servicing cost in Singapore?

In 2025, aircon servicing in Singapore will cost SGD 35–150/unit for general cleaning, SGD 80–250/unit for chemical washing, and SGD 150–450/unit for overhauls. Costs vary by unit and service type.

Aircon Servicing Processes

Learn what aircon servicing in Singapore involves and what the professional requirements are.

What is included in general aircon servicing?

General aircon servicing in Singapore includes cleaning filters, fan coils, drain pipes, and panels, plus checking refrigerant and system performance. Technicians ensure HDB-compliant efficiency. Book pros like DW Aircon via Homees for thorough maintenance that prevents leaks.

Can I service my aircon myself in Singapore?

You can clean filters and wipe exteriors for basic aircon maintenance in Singapore, but professional servicing is best for deep cleaning and inspections. Experts like LK Brothers use specialised tools for HDB units. Hire pros via Homees to avoid issues.

Should I consider chemical cleaning if my aircon has no issues?

Chemical cleaning is needed for reduced cooling, leaks, or mould in Singapore aircons, even without obvious issues. If regular servicing maintains performance, it’s optional. Pros like Coolman offer chemical washes (SGD 80–250). Check with Homees’ directory for HDB needs.

How long does an aircon servicing session take in Singapore?

A standard aircon servicing session in Singapore takes 30–60 minutes per unit. Chemical washes or overhauls (SGD 150–450) may take 1–2 hours. To minimise downtime, schedule efficient HDB servicing with Gain City via Homees.

Aircon Troubleshooting and Repairs

Address common aircon issues and repair needs.

How do I know if my aircon needs a gas top-up?

Signs your Singapore aircon needs a gas top-up include warm air, poor cooling, or frequent cycling. Low refrigerant reduces HDB unit efficiency. Technicians like SoCool can inspect and top up gas (SGD 50–200). Book a check via Homees.

What should I do if my aircon still isn’t cooling after servicing?

If your Singapore aircon isn’t cooling post-servicing, issues like refrigerant leaks or faulty compressors may persist. Contact pros via Homees for a detailed HDB-compliant inspection and schedule repairs to restore and upkeep your cooling system.

What are some common aircon problems and how to repair them?

Common Singapore aircon issues include no power (check fuses), frozen units (clean filters), warm air (top up refrigerant), leaks (unclog drains), or cycling (fix thermostats). Hire HDB pros like Coolman via Homees for repairs.

How long will the aircon gas last after topping up?

High-quality aircon gas in Singapore lasts up to 10 years with regular maintenance. Neglect shortens lifespan, requiring frequent top-ups (SGD 50–200). Schedule quarterly servicing with companies like LK Brothers via Homees to maintain HDB unit efficiency.

When should I repair or replace my aircon in Singapore?

Repair your Singapore aircon if it is under warranty or repair costs are low (<50% unit value). Replace it if efficiency drops significantly, saving on bills. Consult Homees’ pros for HDB-compliant assessments and cost-effective solutions.
