Frequently Asked Questions

Wall-mounted installation starts from RM 199 for 1.0–1.5 HP, RM 249 for 2.0 HP, RM 279 for 2.5 HP, and RM 329 for 3.0 HP. Ceiling cassette from RM 290. Window unit from RM 199. Every price includes 7ft copper piping, wiring, vacuum pump evacuation, leak test and commissioning — all confirmed before we start.

The RM 199 base package includes: site survey, 7ft correctly-sized Type L copper pipe, Armaflex insulation, electrical wiring through conduit, PVC drainage, bracket with vibration pads, mandatory two-stage vacuum evacuation (min 15 min), nitrogen pressure leak test, full commissioning, and written job card with 1-month workmanship warranty.

Standard wall-mounted installation takes 2–3 hours for a single unit. Ceiling cassette takes 3–4 hours. Two units on the same day take about 5–6 hours. We never rush — proper vacuum evacuation alone takes a minimum 15–20 minutes.

Yes, absolutely. We perform a two-stage vacuum pump evacuation for a minimum of 15–20 minutes on every installation. Proper vacuuming removes moisture and air from the refrigerant lines, which is essential to protect the compressor and ensure optimal cooling performance. Any installer who skips this step is cutting corners.

We use Type L copper pipe, correctly sized for each unit's HP rating. Type L has thicker walls than the cheaper Type M, making it more durable and resistant to leaks over time. All piping is nitrogen-purged during brazing to prevent internal oxidation.

Yes, we are experienced with condo installations across KL and Selangor. We work within building management rules, coordinate outdoor unit placement on approved ledges or balconies, and handle JMB/MC approval requirements. We also manage after-hours scheduling where buildings restrict daytime drilling.

Every installation carries a 1-month workmanship warranty. If our work causes a gas leak, no cooling, or drainage issues within that period, we return and fix it free of charge. Replaced parts carry a 3-month warranty. Additionally, our installation follows all manufacturer guidelines so your original brand warranty remains fully protected.

Yes. We run electrical wiring through proper PVC conduit from the isolator to the indoor unit. For larger units (2.5 HP and above), we install a dedicated MCB circuit to ensure safe operation. We also fit an outdoor isolator switch for safety and maintenance access.

We use Armaflex-brand closed-cell insulation — 9mm standard for liquid lines and 13mm for gas lines on most installations. For ceiling cassette and longer pipe runs, we use 19mm thickness. Proper insulation prevents condensation, energy loss, and water dripping along pipe runs.

Yes. Ceiling cassette installations are available from RM 290. We handle the ceiling cut-out, suspension mounting, drain pump setup (where gravity drainage isn't possible), and all electrical work. Cassette installations typically take 3–4 hours and are ideal for offices, restaurants, and large open-plan living areas.

Yes. Window unit installation starts from RM 199. We ensure a secure fit with proper sealing to prevent rain and insect ingress, correct electrical connection, and test all functions before handover. Window units are a great budget option for rental properties and older buildings.

Yes, installations proceed year-round in Malaysia. During heavy rain, we ensure the outdoor unit has proper weather protection and that all wall penetrations are sealed with weatherproof silicone. Indoor work is unaffected by weather.

Our technician will check your electrical circuit capacity during the site survey. If the existing wiring cannot safely handle the aircond load, we will advise you on the MCB upgrade needed. We never install on undersized circuits — safety comes first.

We install PVC drain pipe with a minimum 1:100 gradient to ensure condensate flows freely by gravity. For installations where gravity drainage isn't possible (e.g., interior rooms far from external walls), we install a condensate pump. Every drain line is tested with water before handover.

Yes. Dismantling and relocation is available from RM 150 per unit. We carefully disconnect, cap refrigerant lines, dismantle both indoor and outdoor units, and reinstall at the new location with fresh copper pipe and vacuum commissioning.

For most residential split units, the maximum recommended pipe length is 15–20 meters depending on brand and HP. Beyond 7ft (included in base price), additional copper pipe is charged per foot. Longer runs may slightly reduce cooling efficiency, which we advise during the site survey.

Yes, new home installation is one of our core services. We offer whole-house packages with volume discounts — 2–3 units get 5% off, 4–8 units get 10% off, and 8+ units get 15% off. We coordinate with your renovation timeline to install at the optimal stage.

Yes. We handle commercial installations for offices, shoplots, restaurants, clinics, and small warehouses. Ceiling cassette and wall-mounted units are our primary commercial offerings. We also offer annual maintenance contracts (AMC) for ongoing care after installation.

For light use (evenings only), service every 6 months. For heavy use (8+ hours daily), every 3 months. A chemical wash is recommended annually regardless of usage. Malaysia's tropical humidity means units accumulate dirt and microbial growth faster than in temperate countries.

A basic service (from RM 99) includes: filter cleaning, front panel wash, evaporator coil surface cleaning, blower wheel check, drain pipe flush, electrical connections check, thermostat calibration, gas pressure reading, and a full diagnostic report. Takes about 30–45 minutes per unit.

Yes. A clean aircond uses 15–30% less electricity than a dirty one. Clogged filters and coils force the compressor to work harder and longer to reach the set temperature. Regular servicing keeps the unit running at peak efficiency, directly reducing your monthly TNB bill.

A chemical wash (from RM 120) cleans the unit while it stays mounted on the wall — great for regular maintenance. A chemical overhaul (from RM 220) fully dismantles the unit for a deep clean of every internal component — recommended for water leaking, ice formation, or units not serviced in 3+ years.

The most common causes are low refrigerant gas, a dirty evaporator coil, or a faulty capacitor. Our technicians diagnose the exact issue and quote you before any repair starts. Diagnostic fee is RM 88 (waived if repair is done on the same visit).

Switch off the unit if leaking heavily to prevent damage. The most common cause is a blocked drain pipe — usually fixed with a basic service or chemical wash. If leaking continues after a wash, a chemical overhaul is needed to clean the drain pan and internal channels properly.

Common noise causes include: loose front panel (clicking), worn blower bearings (grinding), fan blade imbalance (vibration), or compressor issues (deep humming). Our diagnostic covers all these. Most noise issues are fixed during a basic service or with a simple part replacement.

Check the sticker on your outdoor unit — it states the gas type (R22, R410A, or R32). Or WhatsApp us a photo of the outdoor unit sticker and we'll identify it for you. Never mix gas types — each system is designed for a specific refrigerant.

Yes, we handle commercial wall-mounted and ceiling cassette units for shops, retail outlets, restaurants, offices, and small-to-medium commercial premises. We also offer annual maintenance contracts for offices and commercial properties with flexible scheduling.

An Annual Maintenance Contract includes scheduled servicing (2–4 visits per year), priority booking, discounted repair rates, and free diagnostic visits. AMCs are ideal for offices, shops, and homes with multiple units. Pricing depends on number of units and visit frequency — WhatsApp us for a quote.

Cleaning filters every 2–4 weeks is excellent and extends time between professional services. However, professional servicing reaches internal components you cannot access — evaporator coil deep clean, blower wheel, drain pan, electrical connections, and gas pressure checks that filters alone don't cover.

Musty or sour smells usually indicate microbial growth (mould and bacteria) on the evaporator coil or in the drain pan. A chemical wash kills and removes the biofilm causing the smell. For severe cases, a chemical overhaul provides a deeper clean. Using the aircond in 'fan only' mode for 15 minutes before switching off can help prevent future growth.

Chemical wash starts from RM 120 for a standard 1.0–1.5 HP wall-mounted unit. Ceiling cassette starts from RM 220. Prices vary by unit type and HP size. All prices confirmed before work begins — no hidden charges.

A pressure chemical wash takes approximately 60–75 minutes per unit. This includes protection setup, chemical application, high-pressure rinse, reassembly, testing, and handover. We use waterproof canvas to protect your walls and furniture throughout.

Yes. We use food-safe, non-corrosive alkaline cleaning agents that are safe for families, children, and pets. The chemical dissolves biofilm and microbial growth within minutes without damaging copper coils or aluminium fins.

We recommend a chemical wash at least once every 12 months for normal use. For heavy-use units (8+ hours daily), units near busy roads, or homes with allergies, a 6-month cycle is better. Regular chemical washes extend your unit's lifespan by years.

A basic service (RM 99) cleans filters and surfaces — good for routine maintenance. A chemical wash (RM 120) uses high-pressure alkaline solution to deep-clean the internal coil, blower wheel, and drain channels while the unit stays mounted. Chemical wash removes stubborn biofilm that basic service cannot reach.

If the cause is a dirty evaporator coil or blocked airflow from biofilm buildup, yes — chemical wash often restores cooling. However, if the issue is low gas, a faulty capacitor, or compressor problems, a repair will be needed. Our technician diagnoses the exact cause before recommending treatment.

No. When done correctly, chemical washing extends the life of your unit. We use non-corrosive chemicals at appropriate pressure (80–120 PSI) that clean without damaging fins or coils. Improper chemical wash with acidic solutions or excessive pressure by untrained technicians can cause damage — which is why professional service matters.

Yes. The alkaline chemical solution kills mould colonies and dissolves the biofilm they grow on. For surface mould on the coil and blower, chemical wash is highly effective. For deep-seated mould in the drain pan or back tray, a chemical overhaul (which dismantles the unit) provides a more thorough clean.

Choose a chemical overhaul when: your unit is leaking water persistently after a chemical wash, ice is forming on the coil, the unit hasn't been deep-cleaned in 3+ years, or there's heavy biofilm buildup in the back tray and drain pan. Overhaul fully dismantles the unit for complete internal cleaning.

Chemical overhaul starts from RM 220 for a standard 1.0–1.5 HP wall-mounted unit. Pricing varies by HP size and unit type. The process takes 2–2.5 hours and includes full dismantling, deep soak cleaning, reassembly, gas pressure check, and commissioning.

A full chemical overhaul takes approximately 2–2.5 hours per unit. The indoor unit is carefully dismantled, every component soaked and scrubbed clean, drain pan and back tray sanitized, then reassembled and tested. We protect your space throughout the process.

In most cases, yes. Persistent water leaks are often caused by clogged drain channels inside the unit that a chemical wash cannot reach. Chemical overhaul dismantles and cleans every internal channel, drain pan, and back tray — permanently resolving most leak causes.

If your unit is under 10 years old and the compressor is working well, a chemical overhaul is very cost-effective — it can restore near-new performance for a fraction of the replacement cost. For units over 12–15 years old, we honestly advise whether overhaul or replacement makes better financial sense.

Every internal component: front panel, filters, evaporator coil, blower wheel/fan barrel, drain pan, back tray, drain pipe connection, and indoor housing. The outdoor unit condenser coil is also cleaned if accessible. All parts are soaked in chemical solution, scrubbed, rinsed, and dried before reassembly.

R22 gas top-up starts from RM 120. R410A from RM 150. R32 from RM 180. Price depends on unit HP size and how much refrigerant is needed. Leak check is included with every gas top-up.

No. A properly installed aircond with good flare connections should not lose refrigerant for years. If your unit needs frequent gas top-ups, there is likely a leak that needs to be found and fixed. We always check for leaks before topping up.

Common signs of low refrigerant: reduced cooling, ice forming on copper pipes or the indoor coil, hissing sounds near connections, and higher-than-normal electricity consumption. Our technician can confirm with a pressure gauge reading during a diagnostic visit.

R22 is the older refrigerant being phased out for environmental reasons. R410A is the current standard for most inverter units — higher pressure, more efficient. R32 is the newest, most eco-friendly option with lower global warming potential. Your unit is designed for one specific type — never mix them.

Yes, always. We perform a leak check using electronic detectors and soap solution on all flare connections, valves, and brazed joints before any gas top-up. If a leak is found, we repair it first — otherwise the new gas will just leak out again.

We strongly advise against it. Refrigerant handling requires proper manifold gauges, vacuum equipment, and knowledge of the correct charge weight. Incorrect charging can damage the compressor. Improper R32 handling (it is mildly flammable) poses safety risks.

A gas top-up with leak check takes approximately 30–45 minutes. If a leak needs repair first (e.g., re-flaring a connection), add 15–30 minutes. We always vacuum the line before recharging to remove any air or moisture.

Diagnostic fee is RM 88 (waived if repair proceeds). Common repairs: capacitor replacement RM 80–150, PCB board RM 150–350, fan motor RM 180–280, thermostat sensor RM 80–120, compressor replacement RM 600–1,200. All prices confirmed before work begins.

Before calling us, check: (1) Is the MCB/breaker tripped? (2) Does the remote have batteries? (3) Is the unit receiving power (any LED lights)? If the breaker trips repeatedly, don't reset it — there may be an electrical fault. Call us for diagnosis.

Ice formation usually means: low refrigerant gas, dirty evaporator coil restricting airflow, or a faulty blower motor not circulating enough air. Running the unit with ice makes it worse. Switch off, let it thaw, and book a service — chemical wash or gas top-up usually fixes it.

First try replacing the batteries (AAA). If still not working, try pointing directly at the unit from 1 meter away. If the remote display works but the unit doesn't respond, the indoor unit's IR receiver may be faulty — a simple replacement part we carry on most service visits.

A tripping breaker usually indicates: a failing compressor drawing too much current, a shorted capacitor, or damaged wiring. This is a safety issue — do not keep resetting the breaker. Our technician will diagnose the exact electrical fault and quote the repair before proceeding.

Yes. Same-day emergency repair is available across KL and Selangor. For complete breakdowns, heavy water leaking, or outdoor unit failures, WhatsApp us immediately. Standard hours 9 AM–6 PM; after-hours surcharge of RM 50 applies for 6 PM–10 PM jobs.

Generally, if the repair cost exceeds 50% of a new unit's price, replacement makes more sense. Units over 10–12 years old running R22 gas are good candidates for replacement with a more efficient R32 inverter model. We give honest advice — if repair isn't worth it, we'll tell you.

We service and install all 20 major brands: Daikin, Panasonic, Mitsubishi Electric, York, Midea, LG, Samsung, Carrier, O-General, Fujitsu, Hitachi, Sharp, Acson, National, Sanyo, Toshiba, Electrolux, Gree, Haier, and Hisense. Both inverter and non-inverter models.

Both are excellent brands. Daikin is known for superior compressor technology and energy efficiency. Panasonic offers great value with Nanoe-X air purification. For installation, both use R32 gas in newer models. We install and service both equally — the best choice depends on your budget and specific needs.

Yes, we service all inverter models across every brand. Inverter units require technicians who understand PCB board diagnostics and variable-speed compressor systems. Our team is trained on all major inverter platforms.

Most likely yes. If your brand isn't listed, WhatsApp us the brand name and model number. Our technicians work on all split-type, ceiling cassette, and window unit airconds regardless of brand.

We use original or OEM-equivalent parts that meet or exceed manufacturer specifications. For warranty-covered parts, we always use genuine brand components. We never use cheap knock-off parts that compromise safety or performance.

General guide: 1.0 HP for rooms up to 150 sqft (standard bedroom), 1.5 HP for 150–250 sqft (master bedroom, small living room), 2.0 HP for 250–400 sqft (large living room), 2.5 HP for 400–550 sqft, 3.0 HP for 550–700 sqft. High ceilings, west-facing rooms, and top-floor units may need one size up.

Basic formula: Room area (sqft) × 25 BTU for standard rooms, × 30 BTU for west-facing or top-floor rooms. Example: 150 sqft bedroom × 25 = 3,750 BTU ≈ 1.0 HP (which is ~9,000 BTU). Oversizing slightly is better than undersizing — the unit cools faster and cycles less.

Not always. An oversized unit cools the room too quickly without properly dehumidifying, leaving the air cold but clammy. It also short-cycles (turns on and off frequently), which increases wear and electricity consumption. Right-sizing for your room is more important than going bigger.

Yes. Standard Malaysian ceiling height is 9–10ft. If your ceiling is higher (12ft+ in some landed homes and duplexes), you need more cooling capacity because the air volume is larger. Add roughly 10% more BTU per extra foot of ceiling height.
