AfterFast, Reliable Furnace Repair Across Palmetto Bay
Most furnace and heat pump repairs in Palmetto Bay run $150-$700 and our technicians arrive the same day you call. Because Palmetto Bay has no municipal natural-gas service, nearly every heating call we handle involves a propane-fired furnace or a heat pump, and the coastal salt air here corrodes components faster than just a few miles inland. Call (817) 402-2972 and a live person picks up, 24 hours a day, to schedule your repair or send a technician for an emergency no-heat call.
Our dispatch and scheduling are coordinated from our Miami office, and crews serve Palmetto Bay homes directly. We know the area from Coral Reef Park to the Deering Estate, from the post-Andrew rebuilds off SW 144th Street to the older ranch homes near Franjo Road. That local knowledge matters because heating systems in Palmetto Bay fail in specific ways: propane ignition assemblies foul with humidity, heat pump reversing valves corrode from bay air, and 1990s ductwork starves airflow in ways that overheat heat exchangers. Our Furnace Repair team is trained on nine major brands and carries the parts to fix most failures in a single visit.
Why Coldharbour Heating & Air Is Palmetto Bay’s Preferred Furnace Repair Company
We’ve been serving South Florida since 2003 as an independently owned and operated member of the Kingswell network. The Kingswell Way means four written promises on every job: we say the price before the work starts, we show up in the window we give you, we leave the place cleaner than we found it, and we put our guarantee in writing. Our 365-Day Done Right Promise covers every repair, if it fails within a full year, we come back and correct it at no charge.
Palmetto Bay homeowners call us because we understand what they’re actually dealing with. A technician who doesn’t know this area might miss that your heat pump’s poor heating is a corroded defrost board, not low refrigerant. Or that your propane furnace’s flame sensor is fouled from the humidity that never really leaves South Miami-Dade, even in January. We see these patterns every winter.
Our phones are answered by a live person around the clock, every day of the year. No voicemail trees. No “call back in the morning” when your heat cuts out at 11 PM on a 45-degree night. Background-checked, uniformed technicians arrive in marked vans with the parts to repair Goodman, Rheem, York, Daikin, and five other major brands on the spot.
Heat Pump Repair in Palmetto Bay
Heat Pump Repair in Palmetto Bay means fixing systems that work overtime, not just in winter but year-round, because most homes here rely on a single heat pump for both heating and cooling. The job involves diagnosing refrigerant flow, electrical controls, and the reversing valve that switches the unit between heat and cool modes. Because Palmetto Bay sits directly on Biscayne Bay, salt air corrodes the reversing valve and defrost board long before the compressor itself fails. That’s a failure mode specific to coastal South Miami-Dade, and it takes a technician who knows what to look for. Most heat pump repairs in Palmetto Bay fall in the $150-$700 range.
Reversing Valve and Defrost Board Replacement
The reversing valve is the four-way valve that redirects refrigerant to switch your heat pump from cooling to heating. When it sticks or leaks, you get cool air when you want heat. The defrost board controls periodic defrost cycles that melt ice off the outdoor coil. In Palmetto Bay, bay-air corrosion attacks the electrical connections on both components. We test the valve with a magnet and check board outputs with a multimeter, then replace with parts rated for coastal environments.
Refrigerant Charge and Leak Detection
A heat pump low on refrigerant can’t move enough heat to keep your home warm. We pressure-test the system, locate leaks with electronic detectors and nitrogen tracing, repair the leak, and recharge to manufacturer spec. In the high-humidity Palmetto Bay climate, an undercharged system also struggles with dehumidification, so occupants feel clammy even at 72°F.
Heating Repair in Palmetto Bay
Heating Repair in Palmetto Bay covers propane furnaces, electric heat strips, and the heating side of dual-fuel or hybrid systems. Because natural gas mains don’t serve this area, propane tanks and heat pumps dominate the heating landscape. The work involves ignition systems, flame sensors, gas valves, blower motors, and heat exchangers. Propane combustion produces slightly different byproducts than natural gas, and the orifice sizes in the burner assembly are different, a technician trained only on natural gas can misdiagnose or improperly adjust a propane system. Most heating repairs in Palmetto Bay run $150-$700, with tune-ups at $80-$200.
Propane Ignition and Flame Sensor Service
Propane furnaces in Palmetto Bay rely on either a standing pilot or an electronic hot-surface igniter. The flame sensor, a small rod that confirms ignition, fouls with oxidation and humidity residue. When it can’t detect the flame, the gas valve shuts within seconds for safety. We clean or replace the sensor, check electrode gap on hot-surface igniters, and verify propane pressure at the manifold. It’s straightforward work, but it has to be done right, a misadjusted valve wastes fuel and risks sooting.
Heat Exchanger Inspection
The heat exchanger is the metal chamber where propane burns and air passes over to warm your home. Cracks or corrosion allow combustion gases, including carbon monoxide, into the airstream. In Palmetto Bay’s post-Andrew rebuilds, we often find undersized ductwork creating high static pressure, which overheats the exchanger and accelerates metal fatigue. We inspect with borescope cameras and combustion analyzers. If the exchanger is compromised, we explain the finding and give you a written replacement price before any further work.
Trusted Brands We Service in Palmetto Bay
Our technicians are trained to service nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We stock common failure parts for Goodman, Rheem, York, and Daikin systems locally, which means faster turnaround for Palmetto Bay homeowners. A failed igniter on a Goodman propane furnace or a blown capacitor on a Rheem heat pump often gets fixed same-day because the part is on the van, not on order from a warehouse three counties away. For older post-Andrew systems, we source compatible components that meet current Miami-Dade NOA requirements, so your repair passes inspection if a permit is required.
Common Furnace Repair Problems We See in Palmetto Bay Homes
- Propane flame-sensor fouling in no-natural-gas homes. Without municipal gas service, Palmetto Bay furnaces run on propane, and the humid coastal air causes faster oxidation on the flame sensor rod. The furnace lights, then shuts down within seconds. Cleaning the sensor restores operation, but we also check venting and combustion air because propane requires precise air-fuel ratios.
- Heat pump defrost board failure from salt-air corrosion. The outdoor unit’s defrost board sits exposed to bay breezes carrying salt mist. Corroded relay contacts prevent the board from initiating defrost cycles, so ice builds on the coil and the system loses heating capacity. We replace with boards that have conformal coating or upgraded terminal seals.
- Undersized 1990s ductwork overheating heat exchangers. Post-Hurricane Andrew rebuilds often reused original duct layouts or used quick-turn designs that don’t move enough air for the installed furnace. High static pressure makes the blower work harder and the heat exchanger run hotter than designed, leading to premature cracking. We measure static pressure and airflow, then recommend duct modifications if needed.
- Reversing valve leaks in coastal heat pumps. The reversing valve’s internal slider and seals degrade from thermal cycling and external corrosion. A leaking valve lets high-pressure refrigerant bypass the indoor coil, so you get lukewarm air in heat mode. We confirm with temperature-split tests and amp-draw checks, then replace the valve and recover and recharge the refrigerant.

FAQs About Furnace Repair in Palmetto Bay
Most Palmetto Bay homes use a heat pump for both heating and cooling, or a propane furnace where no natural gas is available. Because Palmetto Bay has no municipal natural-gas mains, heat pumps are the default for homes with all-electric service, while propane furnaces serve homes with LP tanks. Call (817) 402-2972 and we’ll assess your existing setup and explain what’s most practical for your home.
The defrost board or reversing valve has likely failed from salt-air corrosion, which is common in Palmetto Bay’s coastal environment. The defrost board should cycle the unit into defrost mode every 30-90 minutes of heating run time to melt frost from the outdoor coil. When corrosion interrupts that cycle, ice builds and blocks airflow. We test both components and replace with corrosion-resistant parts. Call (817) 402-2972 for a same-day diagnosis.
Yes. Miami-Dade County requires all HVAC equipment to carry a Product Control Notice of Acceptance for the High-Velocity Hurricane Zone, and Palmetto Bay inspectors enforce this strictly. Equipment that isn’t NOA-listed will fail final inspection, forcing a costly swap. We only install and recommend NOA-listed equipment, so your repair or replacement clears permit without rework. Call (817) 402-2972 to confirm your unit’s compliance.
Once a year, ideally before the heating season. Palmetto Bay’s high humidity and salt air mean flame sensors, igniters, and electrical connections degrade faster than in drier inland climates. Our $80-$200 tune-up includes combustion analysis, refrigerant charge verification, electrical testing, and a written report of what we found. Technicians are not paid on what they sell, so the recommendation is honest. Call (817) 402-2972 to schedule.
Yes. We size and service heat pumps for detached workshops, guest houses, and outbuildings throughout Palmetto Bay’s larger residential lots. These units often run ductless mini-splits or small split systems that require proper load calculation for exposed buildings with no wind shelter. We calculate heating and cooling loads based on the structure’s insulation, orientation, and use, then install or repair accordingly. Call (817) 402-2972 for a free estimate on outbuilding heating.
