Hard start kit installation in Stuart

Veteran Owned Business verified member 378772025 Best of Florida Regional Award winner, Excellence in HVAC ServiceBBB Accredited Business, A+ rating

A hard start kit helps a healthy compressor, not a dead one

The outdoor unit hums, strains, and sometimes trips the breaker. A hard start kit gives the compressor extra help getting started.

It won't fix a compressor that's already failed. We test first so you don't pay for the wrong part.

When a kit is the right call

If the compressor is sound but struggling against high pressure on startup, a kit helps, and on an older unit it can buy real time before a replacement conversation. We check the circuit and capacitor, install it, and test the startup.

What the visit covers

  • Compressor startup testing
  • Kit installation or replacement
  • Capacitor check
  • Startup test after install

Hot room issue, Stuart

One of the rooms was hot. The system wasn't distributing air properly. We checked the ductwork and adjusted the airflow to ensure even cooling throughout the space. Now, the room feels comfortable again.

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.

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.

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.

Good to know

What Stuart homeowners ask 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.

Right now

The unit is down and it's hot

(772) 203-2571

Tell us what it's doing. Blowing warm, not blowing at all, water on the floor, a noise that's new. Say how long it's been like that. We'll tell you what it sounds like and when we can be there.
