We are ALV Aircon, so we have a point of view. This checklist works for any company you are considering, including us. Use it to compare two or three providers before you book.
Quick answer: How to Choose an Aircon Servicing Company in Singapore?
Choose a company that is easy to trace, shows its price per unit, gives a written quote, explains any extra work before doing it, has recent and specific reviews, and tests cooling and drainage after the service. Be careful with any provider that adds chemical wash or gas top up without showing you why.
What should a good aircon servicing company have?
Here are the 10 checks in one glance. Details for each follow below.
- A traceable business with a real address and phone number
- A clear price per unit, with the inclusions listed
- No hidden charges
- Honest recommendations, not automatic upselling
- Recent, specific reviews
- Technicians who know your brand and system type
- A written quote and a clear warranty or follow up policy
- A service process you can describe step by step
- Reasonable availability and a follow up plan
- A service model that fits your home or business
Check 1: Is the business easy to trace?
Look up the company name on the business profile search of ACRA, Singapore’s business registry. Then confirm three things: a physical address, a working phone or WhatsApp number, and a Google Business Profile with real job photos and reviews.
A company that exists only as a mobile number and a social media page is harder to reach if something goes wrong after the visit. For reference, ALV Aircon operates from 451 Jurong West Street 42, Singapore 640451, and can be reached at (+65) 6468 9737.
Check 2: Is the price clear and per unit?
Ask whether the quote is per unit or per visit, and what it includes. A fair quote tells you the number of units, the service type and the total cost before the technician arrives.
Final cost depends on unit count, system type, the condition of the aircon and access to the unit. A company that cannot explain what moves the price is a company to question.
Check 3: Are there hidden charges?
A low headline price is not wrong by itself. The risk is what gets added after the technician starts. Ask about these before you agree:
- Extra charges for chemical wash, drain clearing or hard to reach units
- Gas top up charges
- Parts and repair work found during the visit
- Transport or after hours fees
Ask for the total in writing, including anything that could be added later.
Check 4: Does the company push upsells?
This is the most common complaint about aircon servicing, so learn the basic differences:
- General servicing is routine cleaning, drainage checks and operating checks for a unit that is working normally.
- Chemical wash is a deeper clean for heavy dirt, odour, mould like buildup or weak cooling that routine cleaning does not fix. It should be based on the condition of the unit, not a calendar date.
- Chemical overhaul is a more extensive job that involves dismantling the unit. It needs an inspection and a quote first.
- Gas top up is for a confirmed refrigerant issue. Refrigerant runs in a sealed system and is not used up in normal operation, so genuinely low gas usually points to a leak that should be investigated, not simply refilled.
A good technician explains why a service is needed and shows you the dirt, the drain blockage or the fault before charging for more. If a company automatically adds chemical wash or gas to every visit, treat that as a warning sign.
Check 5: Are the reviews recent and specific?
Read the reviews the way you would read them for a restaurant. Look for these:
- Reviews spread over many months, not 20 posted in one week
- Details such as the unit type, the area and what was done
- Owner replies, especially to critical reviews
- Real names and real profile photos where possible
Read the 3 star and 4 star reviews first. They usually describe real friction, such as lateness or unclear pricing.
Check 6: Do the technicians know your brand and system?
Ask directly whether the company services your brand and your system type. ALV services major brands including Daikin, Mitsubishi Electric, Mitsubishi Heavy Industries, Panasonic, LG, Midea, Toshiba, Fujitsu, Hitachi and Samsung, across split, window, casement, ceiling cassette and ducted systems.
Also ask which refrigerant your system uses. Older units may use R22, while newer ones commonly use R410A or R32. A technician who handles them correctly will match the process to your unit.
Check 7: Is the quote and warranty in writing?
The Consumers Association of Singapore (CASE) advises consumers to keep communication with vendors in writing, not just verbal, so there is a record if a dispute arises. Your written quote or booking confirmation should show:
- The number of units and the service type
- The price and any possible extra charges
- The appointment date and time
- Any warranty or free recheck period after the visit
If you cannot resolve a dispute with the company, you can approach CASE for assistance or file a claim at the Small Claims Tribunals.
Check 8: Can the company explain its process?
Ask what happens during a normal visit. For a standard general service, a good answer covers:
- Air filter cleaning
- Fan coil unit cleaning
- Cooling coil and blower check
- Drain pan and condensate drainage check
- Cooling and airflow check
- Electrical and system condition check
- Refrigerant and cooling performance check
- A final test run
Time matters too. ALV lists about 30 to 45 minutes per standard unit for general servicing and about 1 to 1.5 hours per unit for a chemical wash. If a company promises to finish a whole unit in a few minutes, ask what is being skipped.
Check 9: What about availability and follow up?
Ask how quickly you can get an appointment and who you contact if the problem comes back. ALV offers same day and next day options, subject to booking time, location and technician availability.
Also ask what happens if water leaks or a smell returns shortly after servicing. If that has already happened to you, read our guide on why your aircon still smells or leaks after servicing.
Check 10: Does the service fit your property?
A 3 room HDB flat, a condo with four units and an office with a full floor of aircons have different needs. Ask about multi unit pricing for homes, and about a scheduled plan for businesses. ALV offers monthly, quarterly, bi annual and annual maintenance plans for residential and commercial properties.
10 questions to ask before you book
Copy these into a WhatsApp message:
- Is your price per unit or per visit?
- What exactly does the price include?
- What could be charged on top of this?
- Can I get the quote in writing?
- How long will each unit take?
- Will you explain any recommended extra work before doing it?
- Do you service my brand and system type?
- What is your policy if the same problem returns after servicing?
- How soon can you come?
- Can I see recent job photos or reviews from customers in my type of property?
Score each company out of 20
Give each of the 10 checks a score of 0 (fails), 1 (partly) or 2 (clearly yes). Add the totals:
- 16 to 20: Strong choice. Book with confidence.
- 11 to 15: Ask more questions before you commit.
- 10 or below: Look at another provider.
How much does aircon servicing cost in Singapore?
Prices vary by company, so use published starting prices as a benchmark. ALV Aircon’s current starting prices are:
- General servicing: from $30 per unit
- Diagnostic visit: from $60
- Chemical wash: from $100 per unit
- Gas top up: from $80
- Chemical overhaul: quote after inspection
Final cost can vary with unit count, system type, condition, access and any additional work. For a detailed breakdown, see our aircon servicing cost guide.
How often should you service your aircon?
Singapore’s National Environment Agency (NEA) advises servicing air conditioners regularly and getting them inspected annually, and cleaning or replacing the filter once a month. For normal home use, ALV recommends around every three months. Units that run for long hours may need servicing every one to two months, and offices benefit from a planned schedule.
Common mistakes to avoid
- Choosing only on the lowest price
- Booking a chemical wash because a date has arrived, not because the unit needs it
- Accepting verbal quotes with no written record
- Ignoring a small leak until it damages the ceiling or floor
- Hiring a company with no address, no reviews and no way to follow up
How ALV Aircon approaches this
Our approach is simple. We confirm the service and appointment before the visit, inspect the unit, clean and service it, test cooling and drainage, and explain any findings before additional work. If routine servicing is enough, we do not turn the visit into a chemical wash or a repair. We service HDB flats, condominiums, landed homes, offices and retail spaces across Singapore.
If you want a clear price and a straight answer about what your aircon needs, you can book aircon servicing in Singapore with ALV, or message us on WhatsApp with your location, number of units and the problem you are seeing.
Frequently asked questions
How much is aircon servicing in Singapore?
Prices vary by company, unit count and condition. ALV Aircon lists general servicing from $30 per unit, and the final cost depends on the system type, access and any additional work required.
How do I know if an aircon servicing company is trustworthy?
Check that the business is registered, has a real address and phone number, shows recent and specific reviews, gives written quotes and explains extra work before doing it.
Is a chemical wash needed every time I service my aircon?
No. General servicing handles routine cleaning. A chemical wash is for heavy dirt, odour, mould like buildup or weak cooling that routine cleaning does not fix, and should be based on the unit’s condition.
Does a weak aircon always need a gas top up?
No. Weak cooling can come from dirty filters, blocked airflow, drainage issues, component faults or refrigerant problems. The cause should be diagnosed before any gas is added.
How often should I service my aircon in Singapore?
NEA advises regular servicing and an annual inspection. ALV recommends around every three months for normal home use, and more often for units that run for long hours daily.
Can I get same day aircon servicing?
ALV offers same day and next day appointments, subject to booking time, location and technician availability. Send your postal code and preferred timing to check.
What can I do if I have a dispute with a servicing company?
Keep your written quote and messages. You can approach the Consumers Association of Singapore (CASE) for assistance, or file a claim at the Small Claims Tribunals.
