Air conditioning and heat pump repair across every Charleston ZIP — South of Broad, The Battery, French Quarter, Ansonborough, Harleston Village, Cannonborough-Elliotborough, Hampton Park Terrace, West Ashley, James Island, Johns Island, and Daniel Island. Licensed Charleston technicians with salt-air corrosion experience. Fully stocked repair trucks. Written estimate before any work starts. Same-day service on most systems when you book by noon.
Describe your issue. We'll call back within minutes.
Tidal salt spray, 70°+ dew points from May through September, and a mix of 1740s Historic District singles and 2010s suburban heat pumps mean Charleston systems fail in predictable patterns — corroded coils, leaked refrigerant, flooded condensate pans. Our trucks carry parts for the top five failures so most visits finish in a single appointment.
The Charleston repair most inland techs miss. Aluminum fins off The Battery, Lockwood, Lighthouse Point, Clarks Point, and Daniel Island waterfront turn to chalk in 5–7 years. We repair, replace, and recommend corrosion-resistant coatings so the next one lasts longer.
The most common call after salt corrosion. A blown dual-run capacitor stops your compressor from cycling; a slow refrigerant leak freezes the coil. Diagnostic in 10 minutes, part on every truck, most repairs done in under an hour.
West Ashley slabs, James Island crawlspaces, and peninsula attic handlers all see condensate issues. We clear the line, flush the pan, and add a safety float switch so a clog never becomes heart-pine-floor damage.
Four steps between a broken AC and a working one — with a written estimate before we start.
Talk to a real person at the shop. We confirm your address, symptoms, and the soonest appointment.
A licensed technician is assigned to your appointment — most same-day when booked by noon, otherwise next morning.
Full diagnostic on your system with a written estimate before any repair work begins. You approve the cost — zero pressure.
We make the repair, test it under load, and don't leave until the system is running to spec. 30-day workmanship warranty on every fix.
Our repair trucks carry parts for the most common AC and heat pump failures. Most repairs are completed in a single visit — no waiting for parts to ship from a warehouse.
Our AC repair technicians live in Charleston. They went to Academic Magnet, Burke High, or James Island Charter. Their kids ride the same buses yours do. When you call for a repair at your South of Broad, West Ashley, or James Island home, the licensed tech who shows up knows your block, your one-way streets, and what salt air does to an outdoor condenser after six summers.
Book by noon and a licensed technician is usually at your door the same afternoon. Book after noon, we schedule you for the next morning.
Flat diagnostic fee. Written estimate before any repair work begins. You approve the price — no hidden add-ons, no commission-driven upsells.
If the same issue returns within 30 days, we come back and fix it at no additional labor cost.
Real reviews from Charleston homeowners we've fixed systems for — 29401, 29403, 29407, 29412, 29414, 29492, and every neighborhood in between.
Our heat pump stopped cooling the week after Spoleto. Called Coastal Air Plus first thing Monday, tech was out that afternoon, diagnosed a salt-corroded contactor inside an hour, and had us back on before dinner. Handed me the estimate before touching anything. Fair price, explained every step, and flagged some fin damage I should watch.
Water stains showed up on the ceiling under our upstairs air handler in West Ashley. Called Coastal Air Plus, they sent a technician out same-day, found a clogged condensate line, cleared it, added a safety float switch, and walked me through how to keep it from happening again. Written estimate before any work started. Clear, no-pressure repair visit.
1870s single-house in the Historic District, BAR restrictions on the exterior unit, and three other companies wouldn't touch the job. Coastal sent a senior tech who already knew the block. Diagnosed a failing blower assembly, got the BAR-compliant replacement scheduled, and fixed it without asking me to replace the whole system. Customer for life.

Dispatched from downtown Charleston — not routed in from Goose Creek, North Charleston, or Summerville. Down King Street, across the Crosstown, over the Ravenel for Mount Pleasant, up Folly Road onto James Island, or anywhere between — we're the Charleston neighbor already down the street.
