How much does it cost to have a split system air conditioning installed?

A standard back-to-back split system installation including wiring and appropriate permits will cost approximately $600 to $800 depending on season and quality of work. You may find them cheaper but you get what you pay for. The potential exists for a poor installation to cause expensive repair costs down the track and that should be considered. A non-standard split system installation with brackets, ductwork, a long run, or additional power requirements will obviously cost more. ARMA will only ever recommend refrigeration mechanics who have been appropriatley vetted, meeting trade qualifications and business requirements and hold the ARMA smart card You should also get a certificate of compliance for the electrical work. Most states require electricians to install the wiring connecting the indoor and outdoor units, ask your refrigeration mechanic what the laws are in your state.
