About Us

John Costa began his electrical installation and contracting business in 1964. From those humble beginnings the business now known as J&M Costa Enterprises Pty Limited operates from Western Sydney. The Company employs over 50 qualified tradespeople, apprentices, technical and administrative staff along with retail sales staff making it the largest domestic electrical Company in NSW.

In 2001, J & M Costa Enterprises PTY Limited expanded its business to include an air conditioning division which is today known as Costair. At Costair, we pride ourselves on exceptional customer service and superior installations using only the highest quality products. We are a Platinum Plus Dealer with Actron Air, which means we specialise in installing the most technologically advanced and energy efficient air conditioning systems in the market.

Costair is a proudly Australian and family owned Company with Stephen Costa the Managing Director and David Costa the Construction Manager. By choosing Costair as your air conditioning specialist, you are getting the highest quality service, which only 50 years of business expertise can provide.
