Simply one of the best in town! Professional and prompt services. We have booked their services both for residential and corporate spaces. The team, led by Michael, was really warm to deal with, and they tried to be as transparent as possible in guiding us about the repair they were doing. As a repeat client, I cannot recommend them enough. If you want quick response from the team, you can simply contact them through their website. An customer specialist will immediately be in touch with you more

Great professional services. We've had bad experiences with professional cleaners and aircon specialists before, so we were naturally wary about this at first. Fortunately, after our third try, we found the professional partner for our home (and even our home office). You can readily sense that they have been doing this for years because of their efficient system, from booking to dispatching. Their aircon specialists are also skilled and I heard from one of the specialists that they are required to renew their license annually. Great thanks and great job!read more

Your Denki Aircon Service Contractor

We offer a wide range of services for your Denki AC:

Standard Cleaning

Our standard AC cleaning service involves the quick and efficient removal of dirt, grime and dust from your air conditioning unit.  This type of cleaning is not as thorough as what you would expect with an overhaul but will help get rid of window condensation problems and improve indoor air quality.

Aircon repair

We employ qualified and experienced technicians who can carry out all types of Denki AC repairs. Whether you recently purchased a new unit from us or have been experiencing difficulties with your current device, we can handle any problem you may be experiencing.

Aircon gas top-up

Denki’s use R410A as their refrigerant, an eco-friendly gas that will not harm the environment when released if there was a leak from your AC system. However, your air conditioner still requires regular topping up (usually every 3 months) to ensure it functions efficiently and without interruption during this time. If you fail to do so, it might lead to major malfunctions in the future! We provide both liquid and gas top-ups, and our technicians will show you how to do it yourself in the future!

Aircon chemical overhaul

Denki recommends chemical cleaning and oiling your unit once a year (if used regularly). Our aircon chemical service involves putting high-grade chemicals into your AC system, which break down contaminants that have built up over time. This is essential as the back flow of these contaminants can lead to serious malfunctions with your air conditioner.

Annual maintenance contract

We provide annual maintenance contracts for Denki AC units (12 months). We offer two types of arrangements; we send out our technicians every 6 months to carry out the above services, or choose the package where you perform small servicing tasks (the choice is yours!).

About Denki Air Conditioner

The Denki air conditioner was a Japanese invention built in Tokyo, Japan, by The Denki company. It debuted on December 15, 1934, at the Mitsukoshi Department store in Nihonbashi, Tokyo. Today, out of the businesses that started with this air conditioner company, only one remains Daikin Industries Ltd. The company has grown exponentially and currently holds the number one market share for split-type room air-conditioners. They hold around 30% of the total market share and 50% (or more) of Japan’s domestic air conditioning systems.

This invention was under very heavy competition from other companies such as Toshiba Corporation. However, it wasn’t until 1974 when a former employee of Toshiba Corp., Hiroshi Makita, created a company division that specialized in air conditioning and heating production. The Daikin Group is now one of the leading companies in this field and is located in Osaka Prefecture, Japan.

The popular model of Denki air conditioners

The Denki Split Type R32JU Air Conditioner is currently the latest model to be introduced by Daikin Industries Ltd. The air conditioner has a clean, energy-saving design that helps reduce carbon dioxide emission and refrigerant leakage and uses an environmentally friendly refrigerant referred to as “R32” or HFC-32. The room temperature can be easily adjusted using either Fahrenheit or Celsius scale, depending on your preference.

The main feature of this air conditioner model is the remote control accessory that comes with it at no extra cost (other manufactures often charge for this). It also allows you to monitor the temperature through an LCD screen located in the unit’s front panel. Ensures comfortability while adding a touch of modern design to any room.

The Denki air conditioner has various features that come with it, including:

  • The unit is double-insulated, which means no more noise when in use (not like the old window units).
  • Its built-in stabilizer reduces electricity fluctuations and increases energy efficiency. This feature also prevents voltage surges and protects your appliances from being damaged by high voltages while still ensuring a great cooling effect.
  • Reduced weight and size compared to previous models. Now you can easily install it on your own without hiring an expensive contractor or technician. Installation instructions are provided with the purchase, and installation usually takes under 10 minutes for anyone to do it themselves. It also comes with an auto-restart function after a power outage, making it one of the best features for people living in regions where blackouts are common.
  • The auto mode senses the temperature and adjusts itself accordingly to create a comfortable environment.
  • Multi-filters ready: You can purchase multi-filters according to your personal needs and requirements depending on your room’s layout and size as well as other factors such as odours, dust particles, tobacco smoke, pollen etc… (Please refer to for more information).
  • This model includes HANA Sleep Mode, which senses your sleep patterns by checking how much you move around at night (less movement equals deeper sleep) and sets the unit accordingly. When you wake up in the morning, you are more refreshed comfortable.
  • It also comes with a timer function that allows you to set a daily schedule to program the air conditioner unit to go on or off according to your needs which is especially useful for people who have a busy lifestyle and often forget to turn their units off.
