School Air Conditioning Installation

Climate Control At Your Fingertips

Research clearly shows the detrimental effect a poorly managed room temperature will have on productivity and the ability of students to study.
The NUT draws attention to Education Regulations that state temperatures in school classrooms should be 18C at the least. There is no maximum temperature as such but the World Health Organisation suggest that 24C is considered to be a comfortable working temperature with 26C being the maximum to ensure student comfort and maximise concentration and focus.

Following these guidelines we have a target range of 18-24C which we should try to maintain for the benefit of our children.
With classrooms often sealed, huge increases in the use of electrical and IT equipment how can we provide a comfortable environment for our children to develop and prosper. We must also not forget the teaching staff in this equation, they face different challenges on a daily basis and their welfare and happiness must be paramount. If we can help to create the right environment for staff and pupils hopefully we are helping the children of tomorrow!

Installing comfort cooling and heating systems in school classrooms is a vital part of the success of a school, research in the US by Healthy Schools and the Association for Learning Environments proved grades improved in a temperature controlled environment.


  • High temperatures in the classroom can lead to loss of concentration and tiredness
  • The NEU (National Education Union) recommends thermometers in classrooms to monitor and control air temperature. The units supplied by Sub Zero can include this.
  • Each installed unit has been designed to best meet the needs of your building and classrooms to maximise the air flow and effectively maintain the temperature
  • Taking these necessary steps and precautions can improve children and teacher’s concentration in the classroom

Paula Graham, Operations Manager - Alpha Vitality

Craig and his Sub Zero team have been looking after all of our sites over the North East and North Yorkshire areas for a number of years. All of our units have been installed by Sub Zero and their continued support and maintenance is always to the highest standard. The full team are always on hand to discuss problems and attend site should we need them. As we work in a clinical area the team have been very accommodating to our needs and have always attended sites when it suits the practice. Thank you all for your continued support

Ian Gordon - Riverdale Healthcare

Craig installed one of the first air con units in a dental surgery for me around 1997. Since then we have worked together to install well over 100 units in multiple surgery sites in the North East and North Yorkshire , from retro fits to new builds to conversions. Sub Zero's service has always been first class, pricing always fair and competitive and I recommend this company without reservation

We are a tea room / gift shop in South Shields and Sub Zero provided us with our air conditioning system. From an initial survey of the job to providing us with good advice, Sub Zero gave us an extremely high quality installation.... they were amazingly efficient and friendly, completing an impressive job at a very competitive price. Well done and thanks for everything. It's a pleasure to work with a professional team like yours. It makes my job easier and our customers more comfortable.

We have worked with Sub Zero for the last 8 years for all of our air conditioning requirements whether it has been installation, maintenance or repairs. Sub Zero were a vital part of our store expansion programme installing in the region of 150 systems in our new outlets spanning the length and breadth of the UK. The entire Sub Zero team have always given us first class service, extremely high quality installations and they now provide a PPM package to ensure we are compliant and upto date at all times. An excellent company who I recommend without hesitation.

Jim Freeman - Patriot Games Sheffield

As a business that constantly holds in-store events and regularly fills our space with people, it was important that we found the correct solution for Air-Con. Craig and his team recommended and fitted a system for us that has been perfect and problem free for the 5 years we have been using it. Great after care and affordable maintenance contracts. I cannot recommend Sub Zero highly enough. Even if you don't really know what you need, they will be willing and able to help.
