Ojus is a small, unincorporated community in northeast Miami-Dade where most homes were built between the 1950s and 1970s. That matters for HVAC work: original ductwork, tight attic spaces under flat or low-slope roofs, and electrical panels that predate modern efficiency standards all change how a repair or installation should be approached. We’re Coldharbour Heating & Air, an independently owned and operated member of the Kingswell network. We provide AC repair, furnace repair, and AC installation in Ojus with written pricing and a 365-day repair guarantee. Call (754) 354-7289 any time.
Why Ojus Homes Are Different
Ojus sits inland from the coast, which means it misses the ocean breeze that keeps some South Florida neighborhoods a few degrees cooler. Summers average around 90°F with dew points that make the air feel heavy from April through October. Air conditioners here run almost continuously for seven months, and that accelerates wear on compressors, capacitors, and condensate drain lines in ways a seasonal climate never does.
The housing stock adds another layer. Many Ojus homes were built in the 1960s and still have their original galvanized ductwork. In the humid season, that ductwork sweats. Homeowners see ceiling stains and assume the roof is leaking, when the cause is condensation dripping from cold metal ducts in a hot attic. It’s one of the most common calls we take in Ojus, and it requires a different fix than a roof repair. Flat and low-slope roofs also limit attic space, so condensers often sit at ground level or on rooftops, exposed to salt air, heavy rain, and intense sun. Corrosion-resistant components and proper drainage become non-negotiable.
Electrical panels from the mid-century era often need evaluation before a modern high-efficiency system goes in. We check that before any installation quote is finalized, so the written price you receive reflects the full job, not a surprise add-on later.
Styles & brands we work with
Our Main Ojus Services
AC repair and furnace repair are the two calls Ojus homeowners make most often, and AC installation rounds out the work we do here. Each service has its own page with local pricing and job details.
AC Repair in Ojus
AC repair in Ojus usually starts with a system that’s been running hard for months and suddenly quits, or a thermostat that can’t keep up with the afternoon heat. The subtropical humidity here means condensate lines clog more frequently than in drier climates, and that backed-up water can trigger a shutdown or leak into a ceiling. We diagnose the issue, hand you a written price before any work begins, and back the repair with our 365-Day Done Right Promise. Read the full breakdown at AC Repair in Ojus.
Furnace Repair in Ojus
Furnace repair isn’t a winter-only concern in Ojus, because the rare cold snap in December or January is exactly when a furnace that’s been idle for ten months refuses to start. Igniters, flame sensors, and control boards fail from disuse as often as from wear, and we stock common parts for major brands to keep the job moving. No overtime charge, no after-hours runaround. Details are on the Furnace Repair in Ojus page.
AC Installation in Ojus
AC installation in Ojus means matching a new system to a home built before high-efficiency standards existed. Ductwork may need sealing or replacement, the electrical panel may need an upgrade, and the condenser location has to account for a flat roof or a tight side yard. We quote the full job in writing, including any duct or electrical work, before you sign anything. See AC Installation in Ojus for pricing and what to expect.

What pushes a price toward the high end in Ojus is usually ductwork that hasn’t been touched since the 1960s, an undersized electrical panel, or a condenser that sits on a rooftop and takes longer to access safely.

What Ojus Customers Say
"AC died overnight with a newborn in the house. They bumped us up the list and had it running by noon. I about hugged the guy. Fair price even on a rush call."
