General Aircond Service General aircond servicing covers routine maintenance for residential and commercial split units. A standard service includes filter cleaning or replacement, indoor coil wipe-down, drainage check and flush, remote and operation test, and an overall unit inspection. For most Malaysian homes running air conditioning 6–8 hours daily, a routine service every 3 months is recommended to maintain efficiency and catch early faults. - **Price:** From RM80 per unit - **Suitable for:** Wall-mounted split units (residential and commercial), light-use units not yet requiring chemical wash - **Duration:** 30–45 minutes per unit - **Areas covered:** All KL and Selangor ### 2. Aircond Chemical Wash A chemical wash is a full deep-clean of the aircond's internal components. The indoor unit is stripped down: the blower wheel, evaporator coil, and drain tray are removed or isolated, then cleaned with a food-safe chemical cleaning agent to remove mould, biofilm, dust, and mineral deposits. The process restores cooling performance, eliminates odours, removes airborne contaminants, and clears drainage blockages that cause water dripping. **Who needs a chemical wash:** - Unit not cold despite a recently cleaned filter - Water dripping from indoor unit - Musty or unpleasant smell when unit runs - Unit has not been serviced in more than 12 months - Visible black mould or heavy dirt on indoor grille or vents - Unit in a kitchen, restaurant, or high-humidity environment **What is included:** - Disassembly of indoor unit cover and blower assembly - Full wash of evaporator coil, blower wheel, and drain tray using food-safe chemical - Drain line flush and check - Reassembly and sealing - Cooling performance test after service - Drop sheets and floor protection throughout the job - **Price:** From RM130 per wall-mounted unit - **Duration:** 60–90 minutes per unit - **Areas covered:** KL, Selangor, all 35 areas served - **Page:** https://mavisecocool.com/aircon-chemical-wash-kl ### 3. Aircond Repair and Troubleshooting Aircond repair covers faults that prevent the unit from operating normally. Common repair jobs include refrigerant leak detection and repair, PCB replacement, fan motor repair or replacement, compressor assessment, drainage pump replacement, and thermostat faults. The technician uses a diagnostic checklist on arrival to identify root cause before recommending parts or labour. **Common symptoms requiring repair:** - Unit not cold / cooling inadequate (after a clean coil has been ruled out) - Unit not turning on or turning off shortly after starting - Water leaking from indoor unit despite drain check - Unusual noise (rattling, grinding, hissing) - Blinking error light / fault codes on display - Ice forming on copper pipes - **Price:** From RM100 per call (diagnostic fee credited toward repair) - **Duration:** 45 minutes to several hours depending on fault - **Areas covered:** All KL and Selangor - **Page:** https://mavisecocool.com/aircon-repair-kl ### 4. Aircond Installation Installation service covers new aircond installation, relocation of existing units, and replacement of end-of-life units. Mavis Eco Cool installs all major brands: Daikin, Panasonic, Mitsubishi Electric, York, Acson, LG, Samsung, Hitachi. The installation process includes pipe-laying, condensate drain routing, electrical connection to isolator switch, full vacuum and pressure-leak test before first startup, and an operational walkthrough with the customer. **Installation types:** - Single split unit (1 indoor + 1 outdoor) - Multi-split system (multiple indoor units sharing 1 outdoor) - Cassette ceiling unit - Ducted system (commercial/industrial) - Unit relocation (move from one location to another in the same property) **What is included in standard installation:** - Bracket mounting for indoor and outdoor units - Refrigerant copper pipe installation - Condensate drain pipe routing - Power cable connection to dedicated isolator switch - Vacuum and pressure leak test - R32 or R410a initial charge (where required) - Operational test and handover walkthrough - **Price:** From RM250 per indoor unit (standard split, customer supplies unit) - **Duration:** 3–5 hours for a single unit, full day for 3–5 units - **Areas covered:** All KL and Selangor - **Page:** https://mavisecocool.com/aircon-installation-kl ### 5. Aircond Gas Refill (R32 / R410a) Gas refill replaces or tops up refrigerant that has been lost from the system — typically due to a slow leak. Mavis Eco Cool always performs a pressure check and leak detection before any gas refill. Refilling without first identifying and repairing the leak is a waste of money because the refrigerant will escape again. **When gas refill is needed:** - Weak cooling despite a clean evaporator coil - Ice forming on copper pipes connecting indoor to outdoor unit - Hissing or bubbling sound near indoor or outdoor unit - Fault codes E1, E2 or similar on inverter unit display **Gas refill process:** 1. Pressure check the refrigerant lines 2. Leak detection using UV dye or soap test if pressure is low 3. Repair the leak (flare joint, pipe joint, or refer for compressor assessment) 4. Vacuum the refrigerant lines to remove moisture and air 5. Refill to manufacturer specification (R32 for most post-2018 units; R410a for older systems) 6. Measure return-air and supply-air temperature, confirm system performance **Pricing:** - R32 top-up: RM150 per unit (1–2 HP residential) - R410a top-up: RM180 per unit - Leak repair: site-quoted (typically RM80–RM200) - **Duration:** 45–90 minutes per unit including all checks - **Areas covered:** All KL and Selangor - **Page:** https://mavisecocool.com/aircon-gas-refill ### 6. Cassette Aircond Service Cassette aircond units are ceiling-mounted and distribute conditioned air in four directions. They are common in offices, restaurants, clinics, shoplots, and hotel rooms. Cassette service requires working at ceiling height, full floor and furniture protection, and a different disassembly process compared to wall-mounted units. **Cassette service process:** 1. Site inspection — confirm model, access requirements, tonnage 2. Drop sheets and full floor and furniture protection below unit 3. Grille removal and filter clean 4. Coil inspection — proceed to chemical wash if mould or biofilm present 5. Drain pump and drain line check and flush 6. Reassembly, cooling test, drop sheet removal **Who uses cassette service:** - Open-plan offices (single cassette covers 400–600 sq ft) - Restaurants and kopitiams - Shoplots and retail showrooms - Clinics and medical suites - Gyms and hotel rooms **Recommended service frequency:** Quarterly for offices in daily use. After-hours service is available by arrangement. - **Price:** From RM350 per unit - **Duration:** Approximately 2 hours per unit - **Areas covered:** All KL and Selangor, strong demand in PJ, Subang Jaya, Shah Alam, KL City Centre, Mont Kiara, Damansara - **Page:** https://mavisecocool.com/cassette-aircond-service ### 7.

Include the aircond brand, what problem you are experiencing (not cold, leaking, smelly, overdue for service), and your area. Photos of the unit and any fault codes on the display help speed up the quote. Message at any time — replies during working hours (Mon–Fri 9am–6pm, Sat 9am–3pm). **Step 2 — Quote** Within minutes during working hours, an upfront fixed-price quote is sent via WhatsApp. The quoted price is the final price — no surprise add-ons at the end. If photos suggest a more complex job (leak before refill, compressor fault), the revised scope and price are explained before a technician is dispatched. The customer decides whether to proceed. **Step 3 — Book** Same-day slots are available subject to technician availability. Saturday slots fill fastest. Once booking is confirmed, a 60-minute arrival window is locked in. The technician sends a "on my way" WhatsApp message 30 minutes before arrival — no robocalls, no apps, just a direct message. **Step 4 — Service** The technician arrives in a branded blue Mavis Eco Cool uniform with company ID. Drop sheets are placed before work starts. For chemical wash, a sealed pump bag system prevents detergent runoff onto walls or furniture. The technician narrates key findings during the job. If any out-of-scope faults are found, the customer is informed before additional work proceeds. **Step 5 — Workmanship Warranty** Every job carries a 30-day workmanship warranty. If the same fault returns within 30 days, Mavis Eco Cool returns and fixes it at no charge. Parts replaced carry the manufacturer's warranty. **Payment methods:** Cash, DuitNow / FPX bank transfer, corporate invoice for commercial accounts. --- ## Certifications and Credentials ### SSM Registration Mavis Eco Cool is registered with Suruhanjaya Syarikat Malaysia (SSM), the government body responsible for company registration in Malaysia.

Troubleshooting and repair starts from RM100 per call. R32 gas top-up from RM150. New split unit installation from RM250. Cassette servicing from RM350. All prices are quoted upfront on WhatsApp before any technician is dispatched. **Q: How often should I service my aircond?** A: For a typical Malaysian home, a routine service every 3 months and a full chemical wash every 6–12 months. High-usage environments (offices, F&B, families with small children or pets) benefit from quarterly chemical wash. Cooling towers need monthly maintenance and chemical dosing. **Q: What is the difference between a normal service and a chemical wash?** A: A normal service is a light clean — filter rinse, coil wipe, drain check. A chemical wash is a full deep-clean: the blower wheel, coil, and drain tray are removed or isolated and washed with a food-safe chemical agent to remove mould, dust, and biofilm. A chemical wash restores cooling performance. **Q: Why is my aircon not cold?** A: Three common causes: (1) dirty filter or coil blocking airflow — resolved with a chemical wash; (2) low refrigerant gas — needs a pressure check, leak repair, and refill; (3) faulty compressor — requires diagnosis. A troubleshooting call from RM100 covers diagnosis and the fee is credited toward the repair. **Q: Can I get same-day service?** A: Yes, subject to technician availability. WhatsApp before 12pm for the best chance of a same-day slot. Saturday slots fill fastest — message early in the week for weekend bookings. **Q: What aircond brands do you service?** A: Every major brand in Malaysia: Daikin, Panasonic, Mitsubishi Electric, York, Acson, LG, Samsung, Hitachi, plus Toshiba, Sharp, Midea, and Fujitsu. **Q: Do you service commercial premises?** A: Yes. Offices, shoplots, restaurants, clinics, gyms, hotels, factories. Cassette aircond service and cooling tower maintenance are specifically designed for commercial clients. Corporate accounts can request tax invoices. **Q: What areas do you cover?** A: All of Kuala Lumpur and Selangor — 35 areas in total. Core areas include Petaling Jaya, Shah Alam, Subang Jaya, Puchong, Cheras, Kajang, Ampang, Damansara, Mont Kiara, Bangsar, OUG, Kepong, Klang, and KL City Centre. **Q: Do you provide a warranty?** A: Yes. Every job carries a 30-day workmanship warranty. Installations carry 12 months. Parts carry the manufacturer warranty. Terms are confirmed before any paid work begins. **Q: How do I contact Mavis Eco Cool?** A: WhatsApp or call 019-221 7190. Email mavis.eco.cool@gmail.com. Operating hours: Monday to Friday 9am–6pm, Saturday 9am–3pm. Same-day booking available on WhatsApp. **Q: Are you SSM and CIDB registered?** A: Yes. Mavis Eco Cool is SSM-registered (company registration) and CIDB-certified (HVAC contracting). Certificates available on request. **Q: Can I supply my own aircond and just pay for installation?** A: Yes. Many customers purchase from Lazada, Shopee, or a brand showroom and hire Mavis Eco Cool for installation only. Installation pricing (from RM250 per indoor unit) is the same regardless of where the unit was purchased. **Q: Do you handle multi-unit homes and offices?** A: Yes. Most weekly volume is multi-unit work — homes with 3–6 units, offices with 4–10 cassettes, condos with shared outdoor ledges. A per-unit discount applies for 3 or more units in a single visit. --- ## Key Pages - Home: https://mavisecocool.com/ - About: https://mavisecocool.com/about - Our Story: https://mavisecocool.com/our-story - Services: https://mavisecocool.com/services - Service Areas: https://mavisecocool.com/service-areas - Gallery: https://mavisecocool.com/gallery - Clients: https://mavisecocool.com/clients - Contact: https://mavisecocool.com/contact - Certifications: https://mavisecocool.com/certifications - How We Service: https://mavisecocool.com/how-we-service - FAQ: https://mavisecocool.com/faq - Solutions: https://mavisecocool.com/solutions - Aircond Chemical Wash: https://mavisecocool.com/aircon-chemical-wash-kl - Aircond Repair: https://mavisecocool.com/aircon-repair-kl - Aircond Installation: https://mavisecocool.com/aircon-installation-kl - Aircond Gas Refill: https://mavisecocool.com/aircon-gas-refill - Cassette Aircond Service: https://mavisecocool.com/cassette-aircond-service - Cooling Tower Maintenance: https://mavisecocool.com/cooling-tower-maintenance
