Frequently asked questions

Straight answers about AC service, construction, and how O'Brien works.

How fast can you come out for AC repair?

We guarantee a call-back within 30 minutes during business hours, and we prioritize no-cool calls so you're not left sweating in the South Florida heat. Call or text 954-205-1381 and we'll get you scheduled as fast as possible.

Do you handle no-cool emergencies?

We treat no-cool situations as a priority and move fast to get your air running again during business hours. Call 954-205-1381 and we'll tell you exactly what we can do and when.

What areas do you serve?

We're based in Fort Lauderdale and serve 36+ communities across Broward and Palm Beach counties — including Hollywood, Pompano Beach, Pembroke Pines, Coral Springs, Plantation, Davie, Sunrise, Weston, Boca Raton, Delray Beach, and West Palm Beach. Don't see your city? Call — we likely cover it.

How much does a new AC system cost in South Florida?

It depends on your home's size, your ductwork, and the system's efficiency, so we give you a clear, no-pressure estimate before any work. As a general guide, a new central AC system in South Florida typically runs from about $6,500 to $14,000 installed — we'll size yours correctly and explain every line.

Should I repair my AC or replace it?

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 are often cheaper to replace over time. We'll diagnose the real problem, explain your options honestly, and never push a replacement you don't need.

Do you do both AC and construction?

Yes. O'Brien handles air conditioning service and construction services — AC repair, installation, maintenance, additions, renovations, and build-outs. One accountable team, one clear point of contact.

What's included in your Five-Point Tune-Up?

Our Five-Point Tune-Up covers the drain line, mechanical components, air flow, electrical connections, and refrigerant — the five areas where South Florida systems most often run into trouble. When you book a repair or sign up for a maintenance plan, we include the tune-up at no charge.

How often should I service my AC in Florida?

Because Florida systems run nearly year-round in heat, humidity, and salt air, we recommend a professional tune-up at least once a year — twice is even better. Regular maintenance catches small issues before they become expensive breakdowns.
