Air conditioning service in Key West and Stock Island
Key West is the end of the road, and it's some of the toughest territory in the country for air conditioning. Salt air on every side, year-round humidity, older buildings and tight lots all add up. We service the whole island and neighboring Stock Island.
What makes Key West AC different
- Older buildings. Many Old Town homes and guesthouses were never built for central air. Ductless mini-splits are often the cleanest fix, since they don't need ductwork.
- Tight spaces. Condensers on roofs, balconies, narrow side yards and porches are common. Placement matters for airflow and for neighbors' noise.
- Historic districts. Some properties have rules about where outdoor equipment can go. Ask us early and we'll plan around it.
- Rental and short-term properties. When guests are in the house, a dead AC is an emergency. Our monthly maintenance plan helps prevent it.
- Salt on everything. Outdoor coils and fittings corrode faster here than almost anywhere. Cleaning and inspection help them last.

Common questions
Do you serve Stock Island?
Yes. Stock Island is part of our Key West service area.
Can you add AC to an old Key West home with no ducts?
Usually, yes. A ductless mini-split needs only a small line set between the indoor and outdoor units, so it's a common fit for older buildings. Call for a free estimate.
Do you work on vacation rentals and guesthouses?
Yes. We handle repairs, installs and maintenance for rentals and small lodging. See commercial AC.
Are you available on weekends and holidays?
Yes, 24/7. Call 305.988.0965.
