Air conditioning service in Port St. Lucie that starts with what broke

The house is warm and the thermostat says it shouldn't be. You want to know what's wrong and what it costs. That's the whole job of air conditioning service in Port St. Lucie, and it's where we start.

We look at the whole system first, not just the part that's making noise. Then you hear what failed, what it costs to fix, and whether the fix will last.

Most no-cool calls are one part

A capacitor that won't start the fan. Or a contactor with pitted points. Sometimes it's a drain line full of algae that trips the float switch, or a condenser coil packed with grass clippings.

Those are repairs, and most of them are finished the same visit. A failed compressor on an old unit is a different conversation. We'll have it with you honestly.

Four steps, every call

It's the same routine whether it's a capacitor or a rooftop unit.

  • Inspect the whole system, not just the symptom.
  • Pin down the root cause.
  • Repair it with parts that match the equipment.
  • Test it before we leave.

You decide whether to repair or replace

If a repair will hold, we say so. If it won't, you get the repair number and the replacement number side by side. A typical replacement around here runs about $7,000 to $8,000.

Nobody here earns more when you pick the bigger number. That's on purpose.

Two years on labor, and financing if you need it

Residential installs carry a 2-year labor warranty from us, plus the manufacturer's 10-year parts warranty. Repairs over $500 can be financed, with approved credit.

What we work on

  • AC repair
  • Replacement and new installs
  • Emergency no-cool calls
  • Maintenance
  • Duct sealing and repair
  • Mini splits
  • Indoor air quality, when it fixes a real problem

Real calls, with photos from the job

AC drain line fix, Port St. Lucie

The drain line had backed up because there was no trap. We cleaned the line to ensure proper flow and installed a trap to prevent future backups. Now the unit can drain safely and efficiently.

AC drain line cleaning, Port St. Lucie

The unit kept shutting off. Clogged condensate drain. We flushed the line, treated it for algae, and watched it drain clean before we left, so the water ends up outside and not on the ceiling.

New condenser on a fresh pad, Stuart

New system, new concrete pad. We ran clean line sets, did the electrical to code, pressure tested, pulled a vacuum, and charged it. Airflow checked before we called it done. Permitted and inspected.

York system at a local business, Port St. Lucie

A commercial York system and a wall-mounted mini split at the same business. We serviced the outdoor condensers and the cooling equipment so the place stays cold through August.

Good to know

Questions people ask before they call

Repair, replacement, maintenance, and emergency no-cool calls, plus ductwork, mini splits, and indoor air quality. Homes and light commercial buildings.
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.
