Emergency AC repair in Port St. Lucie, any hour

It's late, the house is climbing past 85, and somebody in it can't take the heat. You need a person, not a voicemail. For emergency AC repair in Port St. Lucie, we answer 24/7.

Sundays and holidays are billed at double time. We'll say so on the phone, before anyone drives out, so the bill isn't a surprise.

Four things to check before you call

These take five minutes. Sometimes they solve it.

  • The thermostat is set to cool, and the batteries aren't dead.
  • The breaker for the outdoor unit and the air handler hasn't tripped.
  • The filter isn't clogged solid.
  • The drain line isn't backed up. A full drain pan can shut the system off.

A church was running again before the 8 a.m. service

At 10 p.m. on a Saturday, a 20-horsepower motor failed at a local church. We tracked down a replacement overnight.

It was running before the 8:00 Sunday service. That's what we mean by 24/7.

Most emergencies are one part

A capacitor, a contactor, a frozen coil, a clogged drain. We fix what failed and get the house cooling. If the system really is done, you'll get both numbers once the house is cool enough to think.

If we touched it, we own it

No callback fees on warrantied work. Repairs over $500 can be financed, with approved credit.

What the visit covers

  • After-hours diagnosis
  • Electrical, mechanical, and airflow repairs

No-cool call, fixed same day, Stuart

The house had no cooling. The problem was at the outdoor condenser, and we fixed it the same day. Then we checked the refrigerant, the amp draw, and the supply temperature. It runs quiet now.

AC not working, air handler wiring, Port St. Lucie

Nothing was running. We traced it to an electrical fault in the air handler, working through the control wiring and the motor connections one at a time until we found it. Fixed, tested, cooling.

Rooftop package unit repair, Stuart

Rooftop package unit on a commercial building. We made the repair up top and tested it under load before we came down. A business can't wait a week for cold air.

Aug 13, 2026 · Stuart, FL

AC running but not cooling, Stuart

The AC ran nonstop and the house never got cold. We found the cause, fixed it, and checked the temperature split and airflow before leaving. A unit that runs all day and never catches up is also running up the power bill.

What happens when you call at midnight

Tell us what the unit is doing and who's in the house. JD usually picks up. If he's under a house or on a roof, someone calls you back. Ask about the diagnostic fee and we'll tell you before anyone drives out.

Good to know

Questions people ask before they call

The thermostat, the breaker, the filter, and the drain line. If it still won't cool after that, call us.
That depends on what failed and on the equipment. We tell you the number after we look at the unit, and if replacing it is on the table, you get both numbers.
No. Everyone here is paid hourly, not on commission. When a repair will hold, that's the recommendation.
Yes. We answer 24/7. Sundays and holidays are billed at double time.
