Slim line indoor unit only 200mm high (2.5kW – 7.1kW) & 250mm high indoor unit from (7.1kW – 13.4kW). The lowest overall height. Mitsubishi Electric slim line units have a built in drip tray and do not require an added drip tray mounted under the unit like other manufacturers. Often adding up to 100mm to the indoor unit height and space required.

Where air conditioning installation is not possible due to lack of wall space or concrete ceilings, a bulkhead can be created to house the SEZ system. Its quiet operation makes it suitable for bedrooms, living rooms and other single room residential or commercial uses.


Inverter technology is your key to more comfort throughout the year, whatever the season. By controlling compressor rotation speed more precisely, inverter technology provides high-speed cooling and heating with extra energy savings compared to non-inverter models.

Our ultra compact design saves installation space (indoor unit only 200mm high) and provides a flexible solution.


Indoor units are as quiet as 23-30 dB(A) at low speed, making them ideal for hotel rooms, living rooms and other residential uses.

47 years of delivering excellence

Recently, I needed to replace the 18 year old ducted heating and A/C system in my apartment. When researching options on the internet, I was delighted to see that Needham Air was still in business - having used them 30+ years ago! Paul Needham did a site inspection prior to providing a detailed quote that included how they would would manage the specific challenges of an inner city location and an apartment on an upper level of a large high rise complex. The installation was on time and demonstrated outstanding project/timeline/logistics planning and management. Communication was excellent, staff were professional, very pleasant and demonstrated great teamwork - as did the contractors (electrician John, and plasterers James and Jarrad). I highly recommend Needham Air. It was a very difficult job - and I can’t fault them. My experience definitely confirms that you get what you pay for!

I can’t speak too highly of this family owned and run business. They really care about their customers. They installed my Actron ducted reverse cycle air conditioner over 9 years ago and have serviced and maintained it for me each year. Its used almost daily, continuously 24/7 in summer and hasn’t missed a beat, until recently and it needed a repair. They were quick to respond with a fault diagnosis. Their very polite, respectful and efficient technician came back with the needed part and got us back up and running. Keep up the great work Needhamair !

I am a returning customer to Needham Air. Hard to believe our previous Mitsubishi reverse cycle air-conditioner stopped working after 24 years! LOL That's why I went straight to Paul Needham to purchase another Mitsubishi reverse cycle air-conditioning unit. Paul's knowledge and professional approach ensured we were happy with the explanation of how the new system worked and it was promtply installed. I highly recommend Needham Air to anyone requiring a reverse cycle air conditioning system.

Needham were the second installer we contacted and absolutely blew the first one out of the water with the quality of their design and the units supplied. Dave's design was efficient and took into account our need to keep everything as hidden as possible from the exterior. The install was fast despite being quite a complicated retrofit, the sparky Mark was great, and everything is practically invisible. Can't recommend Dave, Mark and the team highly enough.

Installation of a ducted reverse cycle airconditioning system, plus removal of an old evaporative system, and 2 old split systems. From the initial showroom contact, thhrough to site assessment, design & installation, the experience was a positive one. The staff (at all stages) were friendly, professional, efficient & worked well as a team. This is our second installation with this company & we would highly recommend.

From the moment David turned up at the house for our quote, I knew this was going to go smoothly. David listened to what we wanted and supplied alternatives, which were excellent. On the follow up meeting with David and the installer the plan, for three seperate systems was further refined. The installation was smooth and on time, the installation was excellent and all rubbish was removed from site. My elderly mother is extremely happy with the final result. All round excellent job

Thanks, Needham Air for your wonderful customer service and attention to detail! You were able to diagnose and repair our A/C system in no time at all and were extremely easy to deal with. We appreciate it very much & wouldn't go anywhere else!
