About Our Services

Cool-Sleep is the branded name for Powrmatic residential air-conditioning and comfort cooling installation solutions with Emerald House Green Engineering Limited, being accredited with relevant trade qualifications such NICEIC for Electrical installations.

As well as being an award-winning Electrical Contractor, we specialise in the supply and installation of bespoke "no condenser outside" air-conditioning solutions to all types of domestic residences and other environments requiring unusual solutions within the South-East.

Through our long established relationship with premium air-conditioning brands such as Powrmatic and Mitsubishi, we can normally find solutions to even the most difficult locations requiring both heating and cooling in particular.  ​

We are part of the Emerald House Group, having the experience of many years working in the industry and having won awards in recent years for innovation and excellence for our work and customer service.

Typically, we install our packaged (condenserless) monobloc vented air-conditioning systems where the customer wants and needs the health benefits of comfort cooling but is unable to (or does not wish to) have any condensers mounted externally. 


These unique and environmentally green solutions also normally negate the need to apply for any planning permission and we have alternative water-cooled options where packaged vented units are unsuitable.  


The majority of our business comes from customers requiring comfort cooling to their bedrooms, loft conversions, conservatories and garden rooms. 

We can normally undertake all works within one day, allowing very little disturbance for you and letting you have the amazing benefits of the systems immediately.
