AC Repair · Fort Lauderdale
AC repair that starts with a real diagnosis, not a guess.
When the air stops in the middle of a South Florida summer, you do not need a sales pitch. You need a prepared technician who finds the actual failure, tells you what it will cost, and gets your home cool again. That is the whole job at O'Brien.

No-cool emergencies
When the house won't cool, the plan gets simple.
A no-cool call is the one situation where speed matters most. Indoor temperatures climb fast in Broward and Palm Beach humidity, and a stalled system can turn a small problem into water damage, a tripped breaker, or a frozen coil. We treat these calls as a priority, confirm your symptoms over the phone, and arrive with the parts and tools that solve the most common failures on the first visit.
Tell us what you are seeing — warm air from the vents, a unit that hums but won't start, ice on the lines, a breaker that keeps tripping — and we will tell you the fastest practical next step before we even pull into the driveway.
Call nowWhat we fix
The failures we see most in South Florida.
Heat, humidity, and salt air are hard on equipment. These are the problems that bring most Fort Lauderdale homeowners to the phone.
Not cooling
Low refrigerant, a frozen coil, a failed capacitor, or a dirty condenser robbing capacity.
Short cycling
Systems that switch on and off too often from a bad thermostat, oversized unit, or sensor fault.
Water leaks
A clogged condensate drain line backing up — the single most common AC service call in Florida.
Electrical faults
Tripped breakers, burned contactors, blown fuses, and failing run capacitors.
Weak airflow
Dirty filters, blocked returns, blower problems, or duct issues choking the system.
Noises & smells
Grinding, rattling, or musty odors that point to mechanical wear or microbial growth.
Our diagnostic process
A real fix beats a fast guess.
Cheap repairs that do not address the root cause cost more in the long run. Here is how we keep that from happening.
02
Diagnose the whole system
We check refrigerant, electrical, airflow, the drain line, and mechanical components — not just the obvious symptom.
03
Explain before we fix
We show you what we found, give you a clear price, and get your approval before any parts or labor begin.
04
Repair and verify
We complete the work, confirm the system is cooling to spec, clean up, and leave you with clear next steps.

How fast can you come out for AC repair in Fort Lauderdale?
We guarantee a callback within 30 minutes during business hours and prioritize no-cool calls so you are not stuck in the heat. Call or text 954-205-1381 and we will get you on the schedule as fast as practical.
My AC turns on but is not cooling. What is wrong?
A system that runs but will not cool is usually low on refrigerant, has a frozen coil, a failing capacitor, a dirty condenser, or a stuck contactor. We diagnose the actual cause instead of guessing, then explain the fix and the cost before we touch anything.
Should I repair or replace my air conditioner?
If your system is under about 10 years old and the repair is minor, fixing it usually makes sense. Older units with major or repeated failures often cost less to replace over time. We give you the honest math and never push a replacement you do not need. If replacement is the better call, see our AC installation page.
Do you charge for a diagnostic visit?
We are upfront about any diagnostic fee when you call, and we apply it toward the repair when you approve the work. You will never get a surprise charge from O'Brien.
Why is water leaking from my indoor AC unit?
In South Florida it is almost always a clogged condensate drain line backing up, but it can also be a frozen evaporator coil thawing or a cracked drain pan. We clear and test the line and check the coil so it does not come back. Regular maintenance keeps drain lines clear year-round.
