Fast, Reliable Furnace Repair Across Kendall
Most furnace repair calls in Kendall aren’t about furnaces at all. They’re heat pumps that ran in cooling mode for eight straight months, and now the reversing valve won’t switch over, or the auxiliary heat strips won’t fire. That’s the reality of heating service in southwestern Miami-Dade, and it’s why our Furnace Repair team trains specifically on heat-pump diagnostics, not just gas-ignition troubleshooting. If your system is blowing cool air when you set it to heat, or the backup heat never kicks in on those rare January mornings, we can usually diagnose it same-day and have the repair written up with a fixed price before any work starts. Call (817) 402-2972 anytime - a live person answers, even at 2 a.m.
We dispatch from our Miami office and keep parts inventory positioned for South Florida’s unique equipment mix. Kendall’s coastal position, just east of Everglades National Park, means salt-laden air accelerates corrosion on outdoor coils and electrical connections. Systems here age differently than they do inland. Our technicians know the difference.
Why Coldharbour Heating & Air Is Kendall’s Preferred Furnace Repair Company
We’ve been serving Kendall as part of the Kingswell network since 2003, and the pattern we see is consistent: homeowners who’ve been burned by out-of-county contractors who don’t understand Miami-Dade’s NOA product-approval system. Those contractors install standard equipment, skip the hurricane-rated anchoring hardware, and the job fails inspection. We don’t. Every repair we perform in Kendall comes with a written price before work begins and a written 365-Day Done Right Promise before we leave.
Our response time to Kendall neighborhoods - from The Hammocks to Country Walk to the townhome clusters off Killian Parkway - is typically same-day for heating calls during the cooler months. We don’t make you wait until morning because your heat pump failed at 10 p.m. A live person answers our phones 24 hours a day, 7 days a week, and we give you a firm arrival window, not a four-hour guess.
What builds trust here is local specificity. We know the 1993-1996 post-Andrew rebuilds have cramped interior air-handler closets and attic ductwork that runs through unconditioned space under low-slope tile roofs. We know the condensate lines clog with algae because Kendall’s flat terrain won’t gravity-drain them. And we know that when a heat pump’s reversing valve seizes after a humid summer, the homeowner often assumes the whole system is shot. Usually it isn’t.
Heating Repair in Kendall
Heating Repair in Kendall means something different than it does up north. Here, it’s almost always heat-pump service: reversing valves that won’t switch from cooling, defrost boards that misread coil temperature, or auxiliary heat strips that won’t energize when the mercury dips to 50 degrees and your home won’t hold temperature. The coastal air accelerates corrosion on outdoor electrical connections, and the near-constant runtime from April through November wears components hard. Most heating repairs we perform in Kendall run $150-$650, with the majority falling in the $200-$400 range for common parts like capacitors, contactors, or defrost sensors.
Reversing Valve and Defrost Diagnostics
The reversing valve is the four-way valve that redirects refrigerant flow between heating and cooling modes. In Kendall, it sits in the outdoor condensing unit, exposed to salt air and operating under pressure for most of the year. When it sticks or the solenoid fails, your heat pump blows cool air regardless of thermostat setting. We test valve operation with a magnet and temperature differential check before recommending replacement - a $400-$650 repair on most residential systems.
Auxiliary Heat Strip Service
Electric heat strips provide backup heat when outdoor temperatures drop below your heat pump’s balance point, roughly 35-40 degrees in this climate. In Kendall’s humid attics, these strips corrode at the terminal blocks and often fail to energize. We test amperage draw across each element and inspect the sequencer - the relay that stages heat strip activation - because a failed sequencer mimics a bad heat strip but costs half as much to fix.
Boiler Repair in Kendall
Boiler Repair in Kendall is a smaller slice of our work, but it’s critical for the neighborhoods that have them - mostly older homes in the eastern Kendall ridge area and some townhome communities with hydronic heating loops. These systems face the same coastal corrosion issues as heat pumps, plus the added challenge of mineral scaling from Miami-Dade’s moderately hard water. A typical boiler repair in Kendall runs $150-$700, with circulating pump replacements and zone valve repairs at the lower end and heat exchanger work at the higher end.
Hydronic Loop and Circulating Pump Service
The circulating pump moves heated water through baseboard or radiant loops. In Kendall’s older homes, these pumps run year-round for domestic hot water production, not just heating seasonally. Bearing wear and capacitor failure are common after 10-15 years of continuous operation. We test pump amp draw, check for air-locked zones, and verify expansion tank pressure before quoting replacement.
Zone Valve and Control Troubleshooting
Zone valves open and close individual heating loops based on thermostat demand. The actuator motors fail from heat and humidity in unconditioned utility closets, and the valve seats develop scale that prevents full closure. A stuck-open zone overheats one area while others go cold. We diagnose with manual override tests and electrical verification at the control panel, then replace only the failed component rather than the entire valve assembly when possible.
Trusted Brands We Service in Kendall
Our technicians carry diagnostic training and common parts for nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Kendall specifically, we see a concentration of Trane and Carrier heat pumps in the post-Andrew rebuilds, with Goodman and Rheem systems common in the 2000s infill and townhome construction. We stock reversing valves, defrost boards, and heat strip kits locally for these brands, which means faster turnaround on repairs and fewer days without heat on those rare cold mornings. If your system is a Lennox or American Standard, we source parts through our Miami distribution relationship with next-day availability on most components.
Common Furnace Repair Problems We See in Kendall Homes
- Reversing valves seize after months of continuous cooling. In Kendall’s climate, heat pumps run in cooling mode from April through November. The reversing valve’s sliding mechanism corrodes in place, and when January arrives, the system can’t switch to heating. The homeowner gets cool air on a heat call, and the fix is valve replacement, not a new system.
- Auxiliary heat strips corrode in humid attic air. Kendall’s relative humidity stays above 80% for five-plus months, and attic-mounted air handlers absorb that moisture. Heat strip terminals oxidize, sequencers fail, and the backup heat never engages on the one cold night you actually need it.
- Condensate clogs from flat-terrain drainage issues. Kendall’s nearly flat elevation means condensate lines lack gravity slope. Algae builds up year-round in the warm, wet environment, backing water into drain pans and triggering float-switch shutdowns that disable heating operation entirely.
- Post-Andrew systems hit simultaneous end-of-life. The 1993-1996 rebuild cohort is now 28-31 years old. Capacitors degrade, control boards develop cold solder joints from thermal cycling, and blower motors draw excessive amperage. These failures cluster; we often find three marginal components on a single service call.
Pricing for Furnace Repair in Kendall, FL
We don’t quote over the phone and then change the number at the door. Our technician diagnoses your system, writes the full repair price on a form, and hands it to you before touching a tool. Here’s what heating repairs typically cost in Kendall:
| Service | Typical Range in Kendall |
|---|---|
| Furnace Repair (diagnostic and repair) | $150-$700 |
| Heating Repair | $150-$650 |
| Boiler Repair | $150-$700 |
What moves the number? Parts matter most. A capacitor or defrost sensor runs toward the low end. A reversing valve replacement, heat strip kit, or control board runs higher. Labor is flat-rated by the job, not clocked by the hour, so a complex diagnosis doesn’t inflate your bill. Every repair includes our 365-Day Done Right Promise in writing: if the same component fails within a year, we return and correct it at no charge. Estimates are free. Call (817) 402-2972 to schedule.

FAQs About Furnace Repair in Kendall
Your reversing valve is likely stuck in cooling mode after running that way for eight months straight. In Kendall’s climate, this is the most common heating call we get, not an ignition failure. The valve sits in your outdoor condensing unit and redirects refrigerant flow between heating and cooling; when it seizes, the system can’t switch modes. We test valve operation with a magnet check and temperature differential before recommending replacement, which typically runs $400-$650. Call (817) 402-2972 for a free diagnostic.
Only if the repair involves replacing the outdoor condensing unit or its mounting pad and tie-down straps. Miami-Dade County requires current NOA-approved equipment and documented hurricane-rated anchoring for any outdoor unit replacement - rules stricter than Broward or Palm Beach counties. A simple reversing valve or electrical repair inside the existing unit does not trigger NOA compliance. If your repair does require unit replacement, we handle the NOA documentation and permit submission as part of the job. Call (817) 402-2972 to discuss your specific situation.
Usually yes, if the heat pump is a 1990s-era system that’s still cooling effectively. These post-Andrew rebuilds used durable equipment, and the components that fail first in Kendall - reversing valves, capacitors, contactors - are replaceable at a fraction of system replacement cost. We evaluate refrigerant charge, compressor amp draw, and heat exchanger condition before recommending anything. A targeted repair often buys 3-5 more years. Call (817) 402-2972 for an honest assessment.
Twice yearly: once before the heavy cooling season (March) and once before the brief heating season (November). Coastal salt accelerates corrosion on outdoor coils and electrical connections, and Kendall’s 80%+ humidity for five-plus months creates condensate drainage issues that don’t self-resolve. Our tune-up runs $80-$200 and includes coil cleaning, refrigerant verification, drain pan treatment, and electrical connection inspection. Technicians are not paid commission on what they find - the report is what it is.
Most repairs fall between $150 and $700, with the majority in the $200-$400 range for common parts. A full diagnostic is always the first step, and we provide a written fixed price before any work begins. The 365-Day Done Right Promise covers every repair at no extra charge. Call (817) 402-2972 for a free estimate - we’ll give you the exact number after we see your system.
