AC Installation & Replacement in Johns Island: Questions We Hear

How long does an AC installation take?

Most residential replacements in Johns Island are finished in one day. Full system changeouts with duct modifications can take two.

What size air conditioner do I need?

It depends on square footage, insulation, windows, ceiling height and orientation. Oversizing is the most common mistake in South Carolina because it short cycles and never removes humidity. We calculate it properly.

Do you offer financing?

Yes. Ask about monthly payment options and current manufacturer rebates when you call.

Yes. We cover downtown Johns Island and every part of Johns Island, plus Wadmalaw Island, Ravenel, Hollywood. Call (855) 459-5498 for the next available window.
