AC repair in Port St. Lucie, without the new-system pitch

The unit is running, the air is warm, and you're bracing for a big number. Usually it isn't one. Most AC repair in Port St. Lucie comes down to a part that costs a couple hundred dollars.

We find that part, hand it to you, and fix it. If it's something bigger, you'll know exactly what and why.

A humming unit usually isn't a dead compressor

A hum with no fan is often a capacitor. Warm air with the fan running can be low refrigerant or a dirty coil. A unit that shuts off after about twenty minutes is often a clogged drain.

We test the circuit, the airflow, and the temperatures before we say anything. Then we show you the part. You see what we see.

Some repairs aren't worth making

A compressor failure on an old R-22 unit is the classic one. The refrigerant is expensive and the rest of the system is tired.

In that case you get both numbers: the repair, and a replacement at about $7,000 to $8,000 for a typical home here. We'll look at your specific unit, give you both numbers, and let you decide.

If we touched it, we own it

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

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.

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.

Good to know

Questions people ask before they call

Capacitors, contactors, clogged drain lines, dirty coils, and fan motors cause most no-cool calls. Most of those are a repair, not a new system.
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.
