Most AC problems show warning signs before the system quits. Below are the most common signs and what each one usually means.
The system runs but the air isn't cold, or some rooms stay warm. Common causes are low refrigerant, a dirty coil, or a failing compressor.
The AC turns on and off in quick bursts. Common causes are low refrigerant, a frozen coil, or a failing control board. Each restart adds wear to the compressor.
Water pooling by the indoor unit usually means a clogged condensate drain line. Ice on the coil or refrigerant lines means restricted airflow or low refrigerant.
Grinding or squealing usually means a worn motor or bearing. A burning smell points to an electrical problem. A musty smell is usually mold in the drain line or ducts.
Most AC and HVAC repairs come down to one failed part, usually electrical, refrigerant, or airflow related. We diagnose the specific component first, then repair that component.
The compressor is the most expensive part in the system. A compressor that won't start is often a failed capacitor or contactor instead. We test those parts first. When the compressor itself has failed, we show you the meter reading and the repair-or-replace cost.
The capacitor starts the compressor and fan motors. It is the most common AC failure, worn down by heat, power surges, and age. A unit that hums but won't start, or a fan that won't spin, usually points to the capacitor. It is the cheapest common repair and often same-day, so we check it first.
Refrigerant runs in a sealed loop and isn't used up. If your AC is low, it has a leak. We find and seal the leak, then recharge to spec. A simple top-off runs low again within weeks. R-410A has gotten expensive, so sealing the leak once costs less than repeat refills.
When the outdoor fan won't spin, the system can't shed heat and the compressor overheats. The cause is usually a failed capacitor, a worn motor bearing, or debris jamming the blades. We confirm the cause before replacing the motor. Routine AC maintenance catches a failing fan motor early, before it damages the compressor.
Dirty coils and clogged drain lines block airflow and stop cooling. In humid climates, an algae-blocked condensate line is one of the most common summer failures. We clear the blockage, clean the coil, and check airflow. A clogged drain line can also overflow and cause water damage, so we test the drain and safety switch.
Our Process
Call or message us and describe the problem. Tell us if the AC isn't cooling, is making noises, is leaking water, or won't turn on.
A technician checks the refrigerant charge, electrical components, airflow, and drain line. The cause is often a different part than the symptom suggests.
You see what we found and get the exact price before any work starts. If replacement is an option, we give you the repair-versus-replace numbers in writing.
We make the repair, test the system, and clean up the work area. We stock common parts for same-day repair.
AC repair is what we do. Frostline is an AC repair specialist. Our technicians work on residential AC and HVAC systems every day. We repair the failed part and show you what we find before we start work.
When a repair no longer makes financial sense, we tell you and explain your AC replacement options. We don't push replacement. Our technicians are licensed, insured, and bonded. Frostline is BBB accredited, and our repairs are backed by a warranty.
We provide AC repair across Delray Beach and coastal Palm Beach County, and we answer the phone 24/7. Frostline prices every job upfront and won't replace parts that are still working.

Answers to the questions homeowners ask most before booking AC repair.
Most repairs run $150 to $650. A capacitor sits at the low end, since the part is cheap and you're mostly paying for the diagnosis and the trip. A compressor can run $1,800 to $2,800 out of warranty. We diagnose first and quote the exact number before any work starts.
Yes. A real diagnosis means a technician measures the refrigerant charge, tests the electrical parts, and checks airflow. We tell you the diagnostic fee upfront before we come out. After-hours emergency AC repair calls cost more because of the higher labor rate.
No. We repair the failed part and show you what failed. A single bad part, such as a capacitor, contactor, or fan motor, is a repair and not a reason to replace the system. We only bring up replacement when the repair cost stops making sense, and we show you the numbers.
Two rules help. The $5,000 rule: multiply the system's age by the repair cost. If the total is over $5,000, compare the cost of replacing the system. The 50% rule: if one repair costs more than half the price of a new system, replace it. A 12-year-old unit needing an $800 repair passes both. We give you the numbers and let you decide.
Yes, and if your system runs on R-410A you don't need to replace it. Older R-410A systems can still be repaired and recharged for their full life. A recharge alone is temporary, though. Refrigerant runs in a sealed loop, so if it's low, it's leaking. We find and seal the leak first, then recharge to spec. R-410A has gotten expensive, so sealing the leak once costs less than repeat refills.
