AfterHVAC Company in Sunset, FL
Most HVAC service calls in Sunset run $150-$650 for repairs and $3,500-$7,500 for a full AC installation, with same-day response available when you call (817) 402-2972. We’re Coldharbour Heating & Air, and we dispatch technicians to Sunset from our Miami office with parts and equipment selected specifically for Miami-Dade’s high-velocity hurricane zone requirements. The homes here face a combination you won’t find many other places: relentless Everglades humidity, aging concrete-block construction with unsealed ductwork, and a county permitting process that’s stricter than Broward or Palm Beach just to the north.
Why Sunset Homes Are Different
Sunset sits at the western edge of developed Miami-Dade, pressed right up against the Everglades. That proximity means our outdoor relative humidity stays elevated nearly every month, even when temperatures dip in January. Your AC isn’t just fighting heat here; it’s working constantly to wring moisture from the air, what we call the latent load. That strain shows up in compressors that cycle too frequently, evaporator coils that ice over from restricted airflow, and ductwork that sweats and grows mold in unconditioned attic spaces.
The housing stock tells the rest of the story. Most Sunset homes are single-story CBS construction built between the 1950s and 1980s, many with flat or low-slope roofs. These houses went up before modern vapor barriers and duct-sealing standards existed. We’ve opened block-wall chases in Sunset homes and found fiberglass ducts that have been leaking conditioned air into the concrete for thirty years. The standing water and organic debris from the Everglades also mean outdoor coils corrode differently here than in coastal zones; it’s moisture and biological growth, not salt, eating the fins.
Then there’s the code layer. Miami-Dade County requires a Notice of Acceptance, or NOA, for every piece of HVAC equipment installed in high-velocity hurricane zones. A technician can’t just grab any AHRI-matched condenser from the supply house. The unit has to appear on Miami-Dade’s approved product list, and the permit inspector will reject anything that doesn’t. We’ve seen contractors who work primarily in Broward get caught off-guard by that requirement. Our technicians carry the current NOA list and spec equipment for it from the start.
Our Main Sunset Services
Homeowners in Sunset call us most often for three things: cooling repairs during the long humid season, heating repairs on those few January mornings when the heat pump switches to auxiliary mode, and full system replacements when age and corrosion finally win. Each service has its own dedicated Sunset page with deeper detail.
AC Repair in Sunset
AC repair in Sunset means dealing with systems that rarely get a break from latent-load demand. We see a lot of frozen evaporator coils from restricted airflow, failed capacitors in heat-stressed outdoor units, and refrigerant leaks at flare connections that have vibrated loose over years of constant runtime. Our trucks carry capacitors, contactors, and refrigerant for Goodman, Rheem, and the other major brands we service, so most AC Repair in Sunset jobs finish in a single visit. Every repair comes with our written 365-Day Done Right Promise.
Furnace Repair in Sunset
True furnaces are rare in Sunset; most homes heat with heat pumps or heat-strip auxiliary systems. When we get a Furnace Repair in Sunset call, it’s usually a failed heat sequencer, a bad limit switch, or a heat pump that’s locked in cooling mode and won’t switch over. We diagnose the electrical controls first, then check airflow through those old block-wall chases that restrict return air. Because we train on York, Daikin, and eight other major brands, the technician who arrives can work on whatever system is already installed.
AC Installation in Sunset
Replacing a system in Sunset requires load calculations that account for the extraordinary humidity, plus equipment selection from the Miami-Dade NOA list. We don’t promise same-day installation; that work gets a written fixed price, a scheduled install date, and all rebate paperwork handled. Our AC Installation in Sunset process includes duct inspection and sealing recommendations, since unsealed ducts in these older homes can waste 20-30% of the new system’s capacity before the first cooling cycle ends.

FAQs About HVAC Company in Sunset
We answer calls with a live person 24 hours a day, and most emergency no-cooling calls in Sunset get same-day dispatch. Call (817) 402-2972 and we’ll give you a firm arrival window.
Yes. Miami-Dade County requires permits for all AC installations and most major repairs, with equipment carrying a Notice of Acceptance for high-velocity hurricane zones. We handle permit paperwork as part of every installation.
Older CBS homes in Sunset often have unsealed ductwork in block-wall chases or hot attics, plus vapor barriers that failed decades ago. The system cools the air but can’t dehumidify effectively when ducts leak or the envelope breathes. We inspect for this on every service call.

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"Furnace was short cycling all winter. They diagnosed a bad sensor instead of condemning the whole unit like I feared. Cheap fix, honest call."
