What Are The 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 

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

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

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

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 

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.

When to Book Aircon Servicing in Singapore

Living in Singapore’s steamy climate, your aircon is probably running non-stop, keeping your HDB flat, condo, or office cool. But all that hard work means dust, mould, and wear can sneak up, making aircon servicing Singapore a must to keep things chill. So, how often should you book HDB aircon servicing, and when’s the right time to call in the pros?

The following questions will help you decide:

• How often do you use your aircon unit?
• Is it for commercial use or residential use?
• Is the room/unit facing a leading road or a construction site?

Whether routine aircon maintenance or an urgent fix, Homees connects you with BCA-trained pros who know top aircon brands in Singapore. Here’s a list of tips to help you keep your aircon in tip-top shape:

Every 3–6 Months for Routine Care

Singapore’s humidity and dust (especially near roads or construction sites) clog up filters fast. Book aircon maintenance Singapore every 3 months if you’re blasting your unit daily (common for HDBs or commercial spaces) or every 6 months for lighter use. General servicing (SGD 35–150/unit) by pros like LK Brothers or Coolman keeps Panasonic or Mitsubishi Electric units humming and prevents pricey breakdowns.

When Cooling Sucks or Bills Spike

If your air conditioner blows warm air or your electricity bill is up 5–15%, it’s screaming for help. Clogged coils or low refrigerant might be the culprit. A chemical washing Singapore (SGD 80–250/unit) or gas top-up (SGD 50–200) restores efficiency, saving you cash on energy costs.

Weird Noises, Smells, or Leaks

Hearing rattles, smelling musty odours, or spotting water drips? That’s your aircon begging for aircon repair in Singapore. Mould, loose parts, or clogged drains are often to blame. A quick servicing session (SGD 35–150/unit) by Harvey Norman pros can fix it before it turns into a sweaty nightmare.

Before the Heat Hits Hard

Singapore’s scorching March–June period puts aircons to the test. Get affordable aircon servicing Singapore before summer to ensure your Samsung or Daikin unit handles the heat like a champ. Book early to avoid the rush—SGD 35–150/unit does the trick.

For Allergy Sufferers

If allergies are a thing in your household, service units with fancy filters (like Panasonic’s nanoe™ or Mitsubishi Electric’s) every 3–6 months. A chemical wash (SGD 80–250/unit) via Courts clears out mould and bacteria, keeping the air fresh and your family breathing easily.

Why Regular Aircon Servicing in Singapore is Essential

If you’re in Singapore, your aircon is your go-to solution for battling that sticky humidity in your HDB flat, condo, or office. But without regular TLC, dust, mould, and wear can turn your cooling buddy into a pricey, wheezy mess. It usually comes with funky smells or even a total breakdown. That’s where aircon servicing in Singapore comes in. Pros like Gain City, LK Brothers, or SoCool can keep your unit purring, save you cash, and make sure you’re breathing clean air. Here’s the lowdown on why HDB aircon servicing is a game-changer in 2025:

Saves Money, Keeps It Cool

Dust and debris clog up filters and coils, slashing airflow by 5–20%. Over time, this reduces your unit’s efficiency, increasing your electricity bill by 10–15%. Routine aircon maintenance (SGD 35–150/unit) cleans everything up, so your unit cools like a champ without burning a hole in your wallet.

Makes Your Aircon Last Longer

Singapore’s grime puts a strain on compressors and fans, which can crap out in 5–10 years if ignored. Regular servicing, including fixes for pesky water leaks, stops wear and tear in its tracks. That means your aircon could keep chilling for up to 15 years, saving you from shelling out for repairs (SGD 50–450).

Cleaner Air, Happier Lungs

Humidity here is a mould and bacteria party, making your aircon smell like old socks and triggering allergies. Chemical washing Singapore pros offer (SGD 80–250/unit) blasts away those nasties, leaving you with fresh, healthy air – perfect for kids or anyone with allergies.

Stops Breakdowns Before They Start

Ever had your aircon leak, make weird noises, or just quit? That’s what happens when drains clog or refrigerant runs low. HDB aircon servicing catches these issues early, sparing you the hassle and cost of emergency fixes.

Keeps HDB Happy

HDB rules say you need BCA-trained techs to service your unit, keeping the building’s exterior looking sharp and meeting safety standards. No stress, no fines—just a cool home.

Some servicing deals even toss in extras like discounts on repairs, free transport, or window solar films to block heat and UV rays, making your aircon even more efficient. Book aircon maintenance Singapore pros through Homees and keep your space cool, clean, and budget-friendly!

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?

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. 

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). 

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.
