A great project installing air conditioning at the new Alcoholery at Willow Farm. The farm is diversifying and the Alcoholery is the latest venture with a cafe, shop and bar on the ground floor and a two bedroom apartment ready for Airbnb tenants on the first floor. We installed Mitsubishi Electric equipment, a 7Kw cassette in the open plan lounge/dinner and a 2Kw cassette in each bedroom both on the superb Multi-Split outdoor. On what was a very hot day the apartment was cooled very quickly to a very comfortable temperature and will be available to hire soon. Call into the Alcoholery to taste proper Somerset cider, unique wines, gin, spiced rum & pork products.

Replacement of 2 x old air conditioning systems at the Cook Shop Cardiff with new Daikin A++ energy rated systems. The Cook shop is unique as it requires cooling 365 days a year due to the display freezers running 24 hours a day. The 19 year old systems we replaced were at best D energy rated and with the new systems A++ rated there will be a significant reduction in the running costs of the air conditioning systems. If you have older air conditioning systems and are thinking of upgrading call us for a free quote.
All Cook food is inspired by the taste of great home-cooking, all Cook meals are prepared in their own kitchens where everything is still prepared by hand.

The new design Daikin MXM Bluevolution Multi-Split air conditioning system installed into a 3 bedroom house, one outdoor MXM unit and 3 x FDX concealed ducted units installed in the loft, one in each bedroom, all indoor units are individually controllable and they operate independently within the same heating or cooling mode
The outdoor unit is fitted with a Dakin swing compressor, renowned for its low noise and very high energy efficiency. Designed for domestic installations the system is A+++ energy rated keeping the energy costs as low as possible at any time of the year when used in cooling or heating.
We used insulated Tecsonic 400 ductwork, this is a high quality insulated & fully flexible acoustic ducting. It is ideal for air conditioning systems where duct borne noise needs to be eliminated, it’s also fire resistant and tested to and complies with BS476.
With only the grilles on the ceiling the concealed ducted system gives you very neat look that the homeowner wanted.
