Heat pump repair and replacement in Port St. Lucie

Heat pump repair when it holds, replacement when it doesn't

It cools fine in summer and does nothing on the first cold morning. Or the reverse. Most homes here run a heat pump, and heat pump repair covers both jobs.

We test it in heat and cool before we recommend anything.

Reversing valves, defrost boards, and leaks

Those cause most heat pump failures. We repair what will last. If a new one is the better path, residential installs carry a 2-year labor warranty from us plus the manufacturer's 10-year parts warranty.

What the visit covers

  • Testing in heat and cool modes
  • Reversing valve and defrost repairs
  • Refrigerant leak repair
  • Full replacement when it's time

Jobs we've finished in Port St. Lucie

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.

Leaking unit repair, Port St. Lucie

The unit was leaking water. A damaged drain line was the issue. We replaced the faulty section and tested the system to ensure everything was sealed properly. A leak can lead to bigger problems if not addressed.

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.

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

What Port St. Lucie homeowners ask us

Repair it when the fix will hold, like a reversing valve, a defrost board, or a leak. Replace it when it won't. You get both numbers.
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.
