Finding a reliable technician for a home split unit in Colombo is harder than it should be. Most search results are car AC workshops, and most of the companies listed in directories work on commercial systems rather than visiting houses.
This guide compares four house AC repair companies in Colombo that take domestic call-outs, with what each one specialises in and the suburbs they cover.
What the guide covers:
- Four companies that service residential split units across Colombo and the suburbs
- The criteria used to pick them, stated openly so you can disagree with them
- Which areas each one covers, from Nugegoda and Maharagama through to Dehiwala and Battaramulla
- A checklist for judging any AC technician before you let them start work
- What to ask on the phone, and the answers that should make you call someone else
Disclosure: this guide is published by Orient Air Conditioning, one of the four companies listed. The criteria are stated in full below, and the other three are included on their merits, not as filler. Judge the list against the criteria rather than taking the order as a ranking.
How this list was put together
Five criteria, applied to every company before it went on the list.
- Takes domestic call-outs. The company visits houses and works on wall mounted split units, rather than only handling offices, hotels and commercial chillers. This rules out most of the firms in Sri Lankan directories.
- Established in the Colombo area. A physical address in Colombo or the surrounding suburbs, not a mobile number alone.
- Does repair, not just installation. Plenty of businesses sell and fit units. Fewer will diagnose a fault on a unit they did not supply.
- Reachable and responsive. A working line, and someone who answers it within a day.
- Transparent about the job. Gives a diagnosis and a price before the work starts.
What the list deliberately does not do:
- No star ratings or scores. Review counts for small Sri Lankan service businesses are thin and easily gamed, so a number here would imply a precision nobody has.
- No ranking order. These are four different businesses suited to different jobs, not first through fourth place.
- No invented detail. Everything stated about the other three companies is verifiable. Where something could not be confirmed, the guide says nothing rather than guessing.
That last point is worth more than it sounds. Most Sri Lankan “top 10” pages list companies that do not exist, with phone numbers that do not connect. If a detail is on this page, it was checked.
The four at a glance
| Company | Based in | Best for | Areas covered |
| Orient Air Conditioning | Nugegoda | Home, office and commercial AC, with a dedicated house AC arm | Nugegoda, Maharagama, Pannipitiya, Kottawa, Boralesgamuwa, Dehiwala, Kohuwala, Rajagiriya, Battaramulla |
| Prestair Ref Engineers | Pannipitiya | Repairing units other firms installed, with a written quote first | Colombo and major cities, islandwide for installation |
| Quick Air Conditioning | Colombo 14 | Gas and leak work, with proper leak detection and pressure testing | Colombo and Western Province, islandwide for emergencies |
| St. Anthony’s Service | Colombo 10 | Longevity, trading since 1942, and fault-led diagnosis | Colombo, wider Sri Lanka for urgent jobs |
The four are not interchangeable. They differ in range, in the suburbs they reach and in whether they will diagnose a unit they did not supply, which is the point of comparing them rather than ranking them.
All four are real companies with published addresses and working contact numbers. What each is best for comes from what the company itself states about its own work, not from a score anyone has assigned.
1. Orient Air Conditioning
Based in Nugegoda. Home, office and commercial air conditioning.
Orient Air Conditioning covers three distinct service lines from its Nugegoda base: house AC repair, office AC repair, and commercial and industrial AC repair.
For a homeowner, the relevant part is that residential work is a service line in its own right rather than something squeezed between commercial jobs. A company that handles office and industrial systems has seen a far wider range of faults than a one-van operator, and the domestic team is not learning on your bedroom split.
What they handle
- Chemical wash and routine servicing
- Gas refilling, with leak detection and repair rather than a top-up
- Compressor diagnosis and replacement
- PCB and control board faults
- Capacitor, fan motor, sensor and swing motor replacement
- Blocked drain clearing, the cause of most indoor water leaks
- Relocating an existing unit during a renovation
Beyond the home, the same team covers office systems including ducted and cassette units, and commercial and industrial installations. Useful if you also manage a workplace, or if your home has a larger system than a standard wall mounted split.
How a job runs
- Diagnosis before a quote. The fault is named and the reading that confirmed it is given to you in writing. No part is ordered on a guess.
- Fixed price before work starts. Nothing is fitted and no gas is charged until the price is approved.
- Leak test before any refill. Refrigerant is not consumed by running a unit, so a system that needs gas is leaking. The leak gets repaired rather than the gas simply replaced.
Areas covered: Nugegoda, Maharagama, Pannipitiya, Kottawa, Boralesgamuwa, Dehiwala, Kohuwala, Rajagiriya, Battaramulla and the surrounding Colombo suburbs. The full list with local response times is on the service areas page.
Book a visit: call or message through orientairconditioning.com. Same-day slots are usually available outside the March to April peak.
2. Prestair Ref Engineers
Based in Pannipitiya. Will repair units other people installed.
Prestair works from High Level Road in Morakatiya, Pannipitiya, covering Colombo and the other major cities, with islandwide reach for installation and replacement.
Two things in their stated practice match what a homeowner should be looking for. They repair units they did not supply, which not every installer will do. And they give a written quotation before ordering parts or starting work, which is the most useful protection there is against a quote that grows once the unit is open.
Their technicians have trained with several manufacturers, including Daikin, Mitsubishi, Panasonic, Haier, Hisense, Gree and Aux.
What they handle
- Repair across the common household faults: water leaks, no cooling, noise and odours
- Routine servicing
- Installation and replacement
- Spare parts and refrigerant gas, held in stock
- Sales of inverter and non-inverter units
Worth knowing: they also handle car AC, refrigerators and washing machines, so this is a general cooling and appliance business rather than a home AC specialist. Their site does not state how long they have traded.
Areas covered: Colombo and major cities, islandwide for installation and replacement.
Contact: No. 110/G, High Level Road, Morakatiya, Pannipitiya. 011 284 9445, mobile 077 748 1958.
3. Quick Air Conditioning Services
Based in Colombo 14. Strongest on refrigerant and leak work.
Quick Air Conditioning has traded since 1998 and runs a team of around 58 staff across residential, commercial and industrial work. Technicians are based in Colombo and the Western Province, with emergency cover offered islandwide.
What stands out for a homeowner is their refrigerant practice. They list electronic halogen leak detection and pressure testing alongside gas charging, across R32, R410A and R22. That is the correct order of work on a unit low on gas, and it is not something most Colombo companies advertise.
What they handle
- Gas charging with leak detection and pressure testing
- Routine and emergency repairs, including compressor and inverter PCB replacement
- High-pressure chemical coil washing and tune-ups
- Inverter installation and relocation for homes, villas and apartments
- Commercial VRF and multi-split systems, and industrial chiller work
Worth knowing: residential is one line among several here, and the industrial side is substantial, so a domestic job competes with larger contracts for attention. Their own site also gives inconsistent figures for how long they have operated, quoting both 25 and 23 years against a 1998 start date, which is worth a question if longevity matters to you.
Areas covered: Colombo and Western Province, with islandwide emergency response.
Contact: No. 20, Mahakumarge Road, Colombo 14. Office 011 584 6768, emergency 077 324 7922.
4. St. Anthony’s Service
Based in Colombo 10. The long-established option.
St. Anthony’s Service has operated since 1942, which makes it by some distance the oldest company on this list. It services homes, offices, shops and commercial buildings from Sri Sangaraja Mawatha in Colombo 10.
Their repair work is described by fault rather than by part, which is a good sign: low cooling and gas issues, water leakage and drainage problems, electrical and sensor faults, and noise or vibration. That is how a homeowner actually experiences a broken AC, and it suggests a diagnostic rather than a parts-swapping approach.
What they handle
- Repair across cooling, drainage, electrical and noise faults
- Maintenance covering filter, coil, blower and drain line, with refrigerant pressure and electrical safety checks
- Installation of split, inverter and ducted systems, including sizing, piping, vacuuming and gas pressure testing
Worth knowing: there is no separate domestic package, so a house call is handled by the same operation that serves commercial clients. The site does not list the specific suburbs it covers, naming Colombo for routine maintenance and islandwide response for urgent jobs, so check your address is served before booking.
Areas covered: Colombo for routine servicing, wider Sri Lanka for urgent call-outs.
Contact: No. 524, Sri Sangaraja Mawatha, Colombo 10. 011 522 5200, WhatsApp 076 731 0310.
House AC repair by area
Colombo is not one service area. A technician based in Nugegoda reaches Maharagama in fifteen minutes and Negombo in two hours, so where you live changes who is worth calling and how fast they arrive.
Nugegoda and Pagoda. The densest cluster of AC businesses in the southern suburbs, which means short response times and real competition on price. Orient Air is based here, and several of the long-established engineering firms sit along Nawala Road and Pepiliyana Road. See AC repair and maintenance in Nugegoda.
Maharagama, Pannipitiya and Kottawa. Mostly served from Nugegoda and Boralesgamuwa rather than by operators based in the area itself. Same-day service is normal, but confirm the call-out covers your address before booking, since some companies quote a surcharge past Kottawa.
Dehiwala, Kohuwala and Kalubowila. Well covered, with several established firms on Dutugemunu Street and around Kalubowila. Worth knowing: homes within about two kilometres of the coast here need servicing every four to six months rather than every six, because salt corrodes the outdoor coil faster.
Rajagiriya and Battaramulla. Newer housing and apartments, so more inverter units and more high-level outdoor installations needing ladder access. Ask whether that access is included in the quote.
Boralesgamuwa and Piliyandala. Served by firms in Boralesgamuwa and Dehiwala. Response times are good on weekdays and slower at weekends.
The full set of areas and what each one costs to reach is on the service areas page.
How to choose a house AC repair company
Ignore the list for a moment. These are the checks that separate a good technician from an expensive one, whoever you call.
Before you book
- Ask whether they work on domestic split units specifically, not just air conditioning generally. A commercial contractor will take the job and send whoever is free.
- Ask whether the call-out fee is credited against the work if you go ahead.
- Check they cover your suburb without a surcharge.
When they arrive
- Ask what failed and how it was confirmed. A technician who names the reading they took is a different proposition from one who says the unit is old.
- Ask for the price before the work starts, not after.
- If gas is involved, ask whether the system was pressure tested for a leak. Refrigerant is not consumed by normal running, so a unit that needs gas is leaking, and a refill without a leak repair means paying again next year.
Before you pay
- Ask what warranty covers the repair and for how long.
- On anything over about Rs 30,000, get a second quote on the same written scope.
Three answers that should make you call someone else
- A compressor quote before the coil has been cleaned. The honest diagnosis order is filter and coil, then drain, then gas and leak, then capacitor, and only then compressor.
- A gas refill with no leak test offered.
- No warranty on the work, which tells you what the technician expects to happen next.
Frequently asked questions
Who is the best house AC repair company in Colombo?
There is no single answer, because the companies in this guide suit different jobs. Some only install and will not diagnose a unit they did not supply. Some work on commercial systems and treat domestic call-outs as an afterthought. The ones worth your call are those that do residential repair as a service line in its own right, and the criteria above are how to tell which is which.
How do I find a reliable AC technician near me in Colombo?
Start with whether they work on domestic split units specifically, then check they cover your suburb without a surcharge, then ask whether the call-out fee is credited against the job. Those three questions remove most of the field before anyone visits.
Do AC repair companies in Colombo visit homes?
Some do and many do not. A large share of the air conditioning companies listed in Sri Lankan directories work on commercial systems, offices and hotels, and will not send a technician to a house for a single split unit. Confirm domestic call-outs when you ring.
Why do most AC repair search results in Sri Lanka show car workshops?
Automotive AC businesses have published far more content targeting the phrase AC repair than home AC companies have, so they dominate the results. Adding home, house or split to your search returns far more relevant results.
Which Colombo suburbs are hardest to get same-day AC service in?
The outer edges, past Kottawa and Piliyandala, and anywhere at weekends. Central southern suburbs such as Nugegoda, Kohuwala and Dehiwala have the densest concentration of technicians and the shortest response times.
How often should a home AC be serviced in Colombo?
Every six months inland, and every four to six months within about two kilometres of the coast, where salt corrodes the outdoor coil faster. There is no cool season here to give a unit a rest, and the monsoon brings humidity rather than relief.
Should I use the company that sold me the unit?
Only while the warranty is live, and check it first, since many homeowners pay for repairs that were still covered. Once out of warranty, an independent house AC specialist is usually faster and cheaper than a brand service desk, which often subcontracts the visit anyway.
