Most common parts on the truck, fixed the same day.
24/7 emergency AC service when you need it most.
Diagnosis before any quote — no upsells, no surprises.
Every Frostline call follows the same path — we diagnose before we price, and explain before we touch anything.
Most companies from Atlantic Avenue to Lake Ida do AC alongside plumbing, electrical, and three other trades. Frostline only does AC — repair, replacement, installation, and maintenance, and nothing else.
We don't do plumbing, electrical, or roofs. Our techs work on home AC, heat pumps, and ductless mini-splits every day — that's the whole job.
Homes on the barrier island, in Seagate, and east of the Intracoastal take constant salt exposure that pits capacitors and corrodes coils. We size repairs and replacements for how fast coastal systems actually wear.
We find the real problem before we put a number on it. No guessing, no upsells, no replacing parts that were never broken.

Straight answers to what people actually ask before they call.
Use the $5,000 rule: multiply your system's age by the repair cost. If the result clears $5,000, replacement is worth comparing. A 10-year-old unit needing a $700 repair lands at $7,000 — a real conversation. We hand you the math, not a sales pitch.
Most common AC repairs in Florida run $150 to $650. A failed capacitor sits at the low end; a compressor can run $600 to $1,800 with parts and labor. We diagnose first and quote the exact number before any work starts.
Salt air. Tiny salt particles settle on metal and pull in moisture, which corrodes coils and pits capacitor terminals. Coastal systems often lose 30 to 40 percent of their lifespan without regular cleaning — closer to 10 to 14 years instead of 15 to 20. Homes east of the Intracoastal, on the barrier island, and in Tropic Isle feel it most.
No. New systems built since 2025 use newer A2L refrigerants like R-454B, but the EPA still allows R-410A systems to be serviced for their full life. We can repair and recharge what you have. We only raise replacement when the repair math stops making sense.
In Florida, the usual cause is a clogged condensate drain line. Your AC pulls gallons of humidity out of the air daily, and that water drains through a line that clogs with algae. When it backs up, a safety switch shuts the system down — or water spills out by the air handler. It's one of the most common summer HVAC calls we run in Delray.
