Good to know

Aircond service questions, answered simply

How much does aircond service cost in KL and Selangor?
Cool7 aircond servicing starts from RM80 per unit, and chemical wash (cuci aircond) starts from RM150 per unit. Repair diagnostic starts from RM120 and is waived if you proceed with the repair. Gas top-up starts from RM180. Cassette, commercial and VRV units are quoted on WhatsApp.

What is a chemical wash for aircond?
A chemical wash is a deep clean that goes further than normal servicing. It strips mould, bacteria and grime from the coils to bring back full cooling and fresher air. Cool7 chemical wash starts from RM150 per unit, and it suits units that smell musty or cool weakly.

What is the difference between aircond servicing and chemical wash?
Servicing is routine upkeep: filter and blower clean, coil and drain check, and a gas pressure check, from RM80 per unit. Chemical wash is a deep coil clean that removes mould and bacteria, from RM150 per unit. Most homes do servicing every 3 to 4 months and a chemical wash every 6 to 12 months.

How often should I service my aircond in Malaysia?
For daily use in Malaysia's heat and humidity, a standard service every 3 to 4 months keeps filters and coils from clogging. A chemical wash is recommended every 6 to 12 months. Skipping upkeep can lead to weaker cooling and higher TNB bills, so a regular schedule saves money.

My aircond is not cooling or leaking water. What should I do?
Switch the unit off if water is dripping, then WhatsApp Cool7 a photo of the unit and tell us your area. We handle not cooling, water leaks, strange noises and electrical faults. Repair diagnostic starts from RM120 and is waived if you go ahead with the repair.

Cool7 is based in Petaling Jaya and travels across KL and Selangor every day, including Subang Jaya, Shah Alam, Puchong, Klang, Kajang, Cyberjaya, Cheras, Ampang, Kepong, Bangsar, Mont Kiara and Damansara. If your area is not listed, WhatsApp us and we will check.

How do I book, and what are your opening hours?
Send a WhatsApp message to +60 10-313 5877 with your area and the problem, then pick a time slot. You can also call the same number. We are open 24 hours, every day of the week, and we give you a written quote before any work starts.

Which aircond brands do you service?
Cool7 services Daikin, Panasonic, Mitsubishi Electric, Samsung, LG, York, Midea, Sharp, Hisense, Acson and more. Not sure about your brand? Send us a photo of the unit on WhatsApp and we will tell you. We work on wall-mounted, cassette and centralized units.

Do you do aircond installation, relocation and gas top-up?

Is there a discount if I have many aircond units?
Yes. Cool7 offers bulk discounts when you service 3 or more units. WhatsApp us how many units you have and your area, and we will quote you. Commercial, cassette and VRV units are quoted individually, so send a photo or the model number if you have it.
