Sunset’s older ranch homes and subtropical climate make HVAC work here different from the rest of Miami-Dade. Most systems run nearly year-round, and the salt air off Biscayne Bay eats at outdoor units faster than homeowners expect. Coldharbour Heating & Air handles repair, maintenance, and replacement work across Sunset with written pricing and a live person on the phone around the clock. Call (850) 810-1910 when a system quits, and we’ll give you a straight answer about what it takes to fix it.
Why Sunset Homes Are Different
Sunset was built out largely in the 1950s, 60s, and 70s, and the housing stock reflects it. Many of the single-family homes still run on original ductwork, and a lot of them have electrical panels that were sized for window units and a couple of appliances, not for a modern high-efficiency air handler. That panel limitation comes up constantly when homeowners ask about upgrading to a newer system.
The climate is the other half of the equation. Air conditioning here isn’t seasonal, it runs ten or eleven months out of the year. The harder challenge is humidity. Sunset sits close enough to Biscayne Bay that the air carries salt, and salt corrodes condenser coils and electrical connections faster than inland neighborhoods see. Summer thunderstorms bring daily lightning, and lightning strikes on outdoor units are a routine repair call from June through September. Our technicians open panels expecting to find corrosion, and they usually do.
One more quirk of Sunset: the neighborhood’s older homes tend to have single-car garages, and a lot of them were built with the air handler tucked into a closet or a garage alcove. When it’s time to replace a system, space matters. A modern air handler is bigger than the one installed in 1968, and squeezing it into the original footprint sometimes takes real planning.
Styles & brands we work with
Our Main Sunset Services
Most calls we take in Sunset fall into one of three categories: a broken air conditioner, a furnace that won’t fire on the rare cold night, or a full system replacement. Each one has its own Sunset page with local pricing and what to expect.
AC Repair in Sunset
An AC breakdown in Sunset in August is a health issue, not an inconvenience. We prioritize those calls and usually get a technician out the same day. Most repairs we see here involve failed capacitors, refrigerant leaks, or condenser coils corroded by the bay air. The fix is often straightforward, and we hand you the written price before any work starts. See AC Repair in Sunset for local pricing and what a typical call looks like.
Furnace Repair in Sunset
Sunset doesn’t get many cold nights, but when the temperature drops into the 40s, aging gas furnaces get called on for the first time in months and some don’t fire. Igniters and flame sensors are the usual culprits, and parts for most brands are stocked in our vans. We carry components for York, Daikin, Bryant, and American Standard so we can usually finish the job in one visit. See Furnace Repair in Sunset for what a repair typically costs here.
AC Installation in Sunset
Replacing an AC in Sunset means matching the new system to a home built with a smaller electrical service and tighter closet space than new construction. We do load calculations before recommending equipment, not after, and we’ll tell you honestly whether your panel can handle a higher-efficiency unit or whether you’re better off with a system that fits the existing wiring. Installation is scheduled, not same-day, because the right equipment has to be ordered for your home’s layout. See AC Installation in Sunset for pricing and what the replacement process involves.

AfterPricing for HVAC Company in Sunset, FL
| Service | Typical range in Sunset |
|---|---|
| AC Repair | $150 – $650 |
| Furnace Repair | $150 – $700 |
| AC Installation | $3,500 – $7,500 |
| Tune-Up | $80 – $200 |
What pushes a Sunset repair toward the upper end of those ranges is usually corrosion. Salt air accelerates wear on coils and electrical connections, and a component that fails from corrosion often takes a neighbor part with it. Whatever the final number, the written price comes before any work begins, and it doesn’t change at the door.

What Sunset 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."
- Celeste Ngo"The repair was done well and quickly. Scheduling over the phone was a little clunky and I got transferred twice, but the tech himself was great and on time."
- Brett Haygood"Thermostat and a weak blower. Fixed both in one visit, explained the guarantee, and didn't leave a mess. I've already recommended them to my neighbor."
