HVAC Company in Key Biscayne, FL

HVAC work in Key Biscayne means servicing homes that sit a few feet above sea level, get hit with salt air every day of the year, and run their air conditioning roughly nine months out of twelve. We’re Dalton Heating & Air, a Garrison Partners company, and we handle AC repair, heat pump installation, and furnace repair across the island. If your system’s struggling or you’re planning a replacement, call (361) 306-9515 and you’ll get a live person, a straight answer, and a written price before any work starts.

Why Key Biscayne Homes Are Different

Key Biscayne is an island, and that changes everything about HVAC. The salt that carries in off the Atlantic corrodes condenser coils and fins faster than almost anywhere else in Miami-Dade. We routinely see outdoor units on Key Biscayne that are seven or eight years old but look like mainland units that have been out there for fifteen. Condensate drain lines clog more often too, since the humid island air means these systems pull gallons of moisture out of the house every day. Homes around Harbor Drive, West Wood Drive, and the Village are a mix of 1960s and 1970s concrete construction and newer builds, and the older stock often has ductwork sized for a system from three decades ago. That matters when you’re putting in a modern heat pump and expecting even cooling in every room.

Permitting here goes through the Village of Key Biscayne and Miami-Dade County, and HOA rules in communities like Towers of Key Biscayne and Ocean Club add another layer. We handle the paperwork on installs and replacements and know what the Village wants to see before the crew rolls up. The geography also means we plan dispatch carefully: there’s one causeway on and off the island, and we schedule Key Biscayne calls so a technician isn’t fighting Rickenbacker Causeway traffic at the worst possible hour.

Our Main Key Biscayne Services

Most of the calls we take from Key Biscayne homeowners are about two things: an AC that stopped cooling, and a furnace that hasn’t run all year and won’t fire when a cold front actually arrives. Here’s what each involves on the island.

AC Repair in Key Biscayne

In Key Biscayne’s salt air, the most common failures we see are corroded contactors, pitted condenser coils, blown capacitors, and clogged drain lines that trigger the float switch and shut the whole system down. A repair here usually runs $150 to $650, and we write the exact price down before we open a single panel. The fix is guaranteed in writing for a full year through our 365-Day Done Right Promise. If it fails inside that window, we come back at no charge. Details are on the dedicated page: AC Repair in Key Biscayne.

Heat Pump Installation in Key Biscayne

A heat pump makes particular sense on Key Biscayne because it handles both cooling and the short-lived cold snaps this part of Florida sees in January and February. The salt exposure means we size the unit, then spec a coastal-rated condenser and coil so you’re not replacing it early. Installation on the island matters as much as the equipment itself: proper elevation off a concrete pad, correct line-set routing, and a clean filter-dryer install. We carry the full line of major brands and give you a written fixed price before ordering anything. Read more at Heat Pump Installation in Key Biscayne.

Furnace Repair in Key Biscayne

Plenty of Key Biscayne homes still run a furnace for the few truly cold nights, and when it fails, it’s usually an igniter, flame sensor, or gas valve issue on a unit that has sat idle for months. Most furnace repairs run $150 to $700, and that number is in writing before we start. We carry common parts for the brands below, which means most furnace jobs on the island are done the same day. See Furnace Repair in Key Biscayne for the full breakdown of what’s covered.
