We diagnose and repair systems that won't cool, leak, or short-cycle — from failed capacitors to bad compressors and clogged drain lines. Most of what we see is a fix, not a new system. A tired air conditioning unit usually has years left in it, and the heat load here is what shortens them.

When your AC dies in July, you can't wait. We answer 24/7 and run same-day diagnostics and repairs. Emergency air conditioning service runs across Delray Beach seven days a week.

New AC systems for additions, renovations, and new-construction homes — load calculation, equipment selection, and a clean, code-correct setup. A new unit is sized for the home, not sold off a shelf. Commercial installs follow the same HVAC standard, and the air conditioning load is calculated either way.

Seasonal tune-ups that catch small problems before peak summer. We clean coils, check refrigerant, and test electrical parts. That service visit covers the whole system, not just the part that failed, and the technician checks the air conditioning end to end.

Mini-split systems for additions, garages, and rooms without ductwork. Efficient cooling with no new ducts required. Mini-splits suit a Delray Beach home with an addition or a converted garage.

We clean and inspect ductwork to clear the dust, debris, and buildup that restricts airflow and rides into your rooms. Clean ducts make the air conditioning work less hard for the same cooling.

Filtration, dehumidification, and ventilation built for Florida humidity, dust, and the allergens a basic filter misses. Indoor air quality is part of the same HVAC system, not a separate add-on.

Light commercial cooling for Atlantic Avenue offices, retail, and storefronts — service and repair that keeps your doors open. Commercial air conditioning service in Delray Beach runs on the same schedule as residential.
Learn MoreWe diagnose before we quote — no cost, no obligation.
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. Every service call in Delray starts the same way, whether it is an AC repair or a full HVAC install quote.
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. HVAC is the only trade we work in, so the technician who arrives has seen your system before.
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. Air conditioning is not a sideline here. Every technician works on the same systems every day, in homes and commercial buildings alike.
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. A system in Delray Beach ages faster than the same unit inland, so the service interval matters more here.
We find the real problem before we put a number on it. No guessing, no upsells, no replacing parts that were never broken. Our services are scoped to what actually failed, nothing padded on top. AC services in Delray run on flat pricing, and the same AC technician handles the whole job.

Straight answers to what people actually ask before they call. Most of it comes down to repair cost versus a new system.
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. The service call fee is credited against the repair.
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. AC repair pricing in Delray Beach is quoted per job, not per hour.
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. Homes near the water need air conditioning service more often, because the salt air works on the coils and the heat never really lets up.
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. Until then, service keeps the system running another season. A well-maintained air conditioning system lasts longer than most people expect, and the service pays for itself. Delray homeowners who book AC services see fewer emergency calls, and an aging air conditioner gets caught early, before the AC quits in August.
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. Summer is when a home puts the most load on its air conditioning, and heating season barely gives the equipment a rest here. Commercial buildings run their AC even longer, and commercial HVAC services follow the same routine as residential HVAC work.
