About AAC Southern
AAC Southern designs, installs, maintains and repairs home air conditioning across East and West Sussex. Based in Littlehampton, it offers domestic units chosen to suit room decor and maintenance contracts for systems installed by other companies.
Published opening hours are Monday to Friday, 9am–5pm.
AAC Southern discusses maintenance options with installation customers and offers maintenance contracts for equipment installed by other companies. For faults, it aims to attend within 48 hours of a call; this is a response target, not a guaranteed attendance time.
A residential project in Hove involved installing a Mitsubishi Heavy Industries wall-mounted single-split system in a bedroom. The company also specialises in domestic units selected to blend with room decor.
The website offers free quotations for home and business installations through an online enquiry form. The supplied pages do not describe a site-survey process or promise free surveys.
AAC Southern states that it is REFCOM registered and that its engineers are suitably qualified. It also claims approved-installer status for most major manufacturers, but does not identify those manufacturers or individual engineering qualifications.
