Dave started the company as David Blakey Services Ltd in 1999, and since joining forces with Steve Byrne and Kevin Sheppard has continued to take the business forward at unprecedented levels. Dave heads up the Contracts Department and along with Richie, their experience has led to bigger and bigger projects being managed by DBS and the opportunity to offer our clients a 7 year warranty on Mitsubishi Electric installations when accompanied by an ongoing maintenance schedule.

Dave says:

With my partners we have built a business which has grown into one of the finest specialist air conditioning, heating and refrigeration companies in the South East.
We have employed the finest engineers and administration support and I am very proud of the growth and the customer relationships we have formed over the past years.
Our intention is to be recognised as the very best air conditioning and heating installation, service and maintenance company.
