Mavis Eco Cool offers six core aircon services across Kuala Lumpur and Selangor. Each is priced upfront, carried out by factory-trained technicians, and backed by a written workmanship warranty. Whether you need a quick chemical wash before the school holidays or a multi-unit cassette AC contract for your office, the same standards apply. Pricing below is per unit for standard 1.0–2.5 HP systems unless stated otherwise. Larger systems are quoted on site.
1. Aircon Chemical Wash
Starting price: RM130 per wall-mount unit · Typical duration: 60–90 min per unit
A proper chemical wash strips the indoor blower, drain tray and evaporator coil, then bathes them in a food-safe cleaning agent to lift years of accumulated dust, mould, biofilm and bacteria. The result is restored cooling power, dramatically improved indoor air quality, and a noticeable drop in your electricity bill because the unit no longer fights through clogged fins. This is the single most cost-effective service for any aircon over 12 months old.
What's included
- Full disassembly of indoor unit, drain tray, blower wheel
- Coil flush with food-safe chemical cleaning agent
- Filter wash, drain pump test, drain line flush
- Reassembly, leak test, cooling performance test
- Drop sheets and floor protection during work
When you need it: Every 6–12 months for typical Malaysian homes; every 3–6 months for offices, restaurants and homes with small children or pets. Also when cooling has noticeably weakened, when the indoor unit smells musty, or when water drips from the front grille.

Starting price: RM100 per call (diagnosis) · Typical duration: 30–90 min
The on-site call covers full diagnosis, with the diagnosis fee credited toward any repair you approve. We handle inverter aircon repair, R32 gas top-up after leak check, drain pump replacement, fan motor swap, capacitor and PCB diagnosis, and compressor replacement on every major Malaysian brand — Daikin, Panasonic, Mitsubishi Electric, York, Acson, LG, Samsung and Hitachi. Most repairs are quoted within 30 minutes of arrival, and parts pricing is shown upfront before any work begins. Emergency aircon repair slots are reserved daily for genuine breakdowns.
What's included
- On-site diagnosis with electrical and refrigerant tests
- Written quote for parts and labour before work begins
- Common fixes performed on the same visit
- Workmanship warranty on every repair
When you need it: Aircon not cooling, water leaking indoors, strange noises, ice forming on coil, error codes flashing on inverter display, or unit refusing to switch on.

Starting price: RM250 per indoor unit · Typical duration: 3–5 hours per unit
A bad install is the silent killer of any new aircon — wrong piping, sloppy vacuum, weak mounting, missing drainage gradient. We install split, cassette and ducted systems with full vacuum, properly insulated piping, secure brackets and tested drainage. Pricing starts from RM250 per indoor unit (within 4 m of piping) and from RM650 for ceiling cassette. We also supply units at distributor pricing if you want a complete supply-and-install package — a popular choice for Daikin aircon service KL and Panasonic aircon repair Selangor customers replacing whole rooms.
What's included
- Site survey and sizing recommendation
- Insulated copper piping (within 4 m), drainage and bracket
- Full vacuum process and pressure leak test
- Cooling performance test and customer handover
When you need it: Moving in to a new home, replacing a unit older than 8–10 years, expanding cooling to a new room, or upgrading from non-inverter to inverter for energy savings.
View Installation Details4. Cassette AC Service & Commercial Servicing
Starting price: RM350 per ceiling cassette · Typical duration: 2 hours per unit
Ceiling cassette units in offices, retail outlets and restaurants run far longer hours than home units, which means they accumulate grease and dust at twice the rate. Our commercial servicing covers cassette inspection, full chemical wash, drain pump and float test, and basic mechanical adjustment. We work after hours and on weekends to suit operating businesses. Multi-unit contracts (5+ units) qualify for a discounted per-unit rate.
What's included
- Ceiling-level access using proper platform or scaffold
- Removal of cover, blower wheel and drain pan
- Chemical wash and reassembly
- Drain pump float and condensate test
When you need it: Every 3 months for restaurants, every 6 months for offices and retail. Also when airflow has dropped or condensation forms on the ceiling around the unit.
5. Cooling Tower Maintenance
Starting price: Quoted on site after free inspection · Duration: Project-based
Cooling towers are the workhorse of large building HVAC and process cooling systems. Without disciplined chemical dosing, regular biocide treatment, and periodic mechanical inspection, towers lose efficiency fast. Our scope covers chemical dosing programmes, conductivity and TDS monitoring, full strip-down chemical wash and sludge removal, fill-pack inspection and replacement, fan motor replacement, drift eliminator restoration, basin cleaning, and pump and float-valve servicing. We also support facilities preparing for water-treatment or DOSH compliance audits.
What's included
- Free initial site inspection and condition report
- Written maintenance plan tailored to duty cycle
- Routine chemical dosing and biocide programmes
- Strip-down wash, fill-pack and fan motor work as needed
When you need it: Capacity loss, scale build-up, drift droplets, new noises, regulatory inspection due, or no maintenance contract in the last 12 months.

Starting price: RM150 per unit (R32) · Typical duration: 30–45 min
An aircon that runs but won't cool the room is usually low on refrigerant. We carry out a leak check first — topping up gas without fixing a leak just delays the problem. Where a leak is found, we braze and re-test before charging fresh R32 gas. Most modern Malaysian wall-mount units use R32; older units may use R22 or R410A and we handle those separately. R32 gas top-up is also a typical sub-step of a larger repair job.
What's included
- Pressure test and leak detection
- Vacuum and refill with correct refrigerant
- Cooling performance test before sign-off
When you need it: Cooling has weakened gradually, ice forms on copper piping outside, or the indoor coil partially freezes during operation.

Maintenance Schedule Guide
How often should you service your aircon? It depends on usage. The schedule below is what we recommend for typical Malaysian climate conditions and works for most of our KL & Selangor customers. If you want the best aircon service Selangor families rely on, this is the rhythm we keep.
- Every 1–2 months: Self-clean the indoor filter at home (rinse, dry, refit). Takes 5 minutes per unit.
- Every 3 months (heavy use): Light professional service — exterior wipe-down, filter clean, drain test. Recommended for offices, F&B and homes with pets, smokers, or small children.
- Every 6 months (typical home): Full chemical wash on at least one of your units. Rotate units across visits if you have multiple.
- Every 12 months (light use): Full chemical wash on all units, plus a refrigerant pressure check. Catch issues early.
- Every 24 months: Inspect outdoor condenser fan motor, electrical contactors, and replace insulation tape on copper piping if degraded.
- Every 8–10 years: Plan for replacement, especially for non-inverter units. Inverter savings now pay back in 2–3 years.
