Air conditioning replacement in Port St. Lucie, priced before you commit

Somebody told you the system is done. Maybe they're right. Before you spend money on air conditioning replacement in Port St. Lucie, you should see the repair number next to it.

We'll give you both. If the unit is worth saving, we'll say so. If it isn't, here's what a replacement looks like with us.

About $7,000 to $8,000 for a typical home here

That's the range for a typical Port St. Lucie replacement. Size, efficiency, and what the ducts and electrical need all move it.

You get the number before we start. It covers the outdoor unit, the indoor air handler or coil, the line set, the electrical, and startup testing.

Permitted, inspected, and tested before we leave

Every install is permitted and inspected. We size the system for the house instead of swapping in whatever tonnage was there.

Trane is what we install most. We've also put in Carrier Infinity inverter systems and Rheem. We pull a vacuum, charge it, and check temperatures at the registers before anyone calls it done.

Sometimes the honest answer is a repair

A capacitor or a drain line is not a reason to replace anything. A dead compressor on a unit past fifteen years might be. We show you which one you have and you decide.

Two years of labor. Most shops give you one.

Every residential install carries a 2-year labor warranty from us, plus the manufacturer's 10-year parts warranty. Most companies around here give you one year on labor.

Financing is available on new Trane systems, including 0% options, with approved credit.

What the visit covers

  • Load calculation and sizing
  • Removal of the old equipment
  • A matched indoor and outdoor system
  • Vacuum, charge, and performance testing
  • Permits, inspection, and code-compliant electrical

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.

Questions people ask before they call

Around $7,000 to $8,000 for a typical Port St. Lucie home, depending on size and equipment. Installs carry a 2-year labor warranty from us plus the manufacturer's 10-year parts warranty.
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.
