Many years ago Delta installed and maintained my first home air conditioning system and more recently installed a fully ducted Daikin system. The service from Delta right from the start has been friendly and of consistent high quality, both from Office and Technical staff. That is why I would like to take the time to thank all concerned. Each and every problem, minor though they may be, has been dealt with in a patient, friendly and always efficient manner. So thanks to all of you and may your business continue to prosper.
