When a furnace quits on a January night in Miami, it’s not just uncomfortable, it’s a problem you want solved before the house cools down. Cold Harbour Heating and Air has been repairing furnaces in Miami since 2003, and we answer the phone with a live person at (850) 810-1910 any hour of the day, any day of the year. Most furnace repairs in Miami run between $175 and $825, and we put that price in writing before a single tool comes out of the truck. Our technicians arrive in uniform, show ID, and carry the training to work on nine major brands including Carrier, Trane, Lennox, and American Standard. If you need Furnace Repair in Miami, we’ll show up in the window we give you and back the work with a 365-day written guarantee.
Furnace Maintenance
Furnace Maintenance is the scheduled service visit that keeps your heating system from failing when you actually need it. In Miami, most furnaces sit idle for months at a time, and that long rest lets dust settle, electrical connections loosen, and small parts corrode in the humid air. When problems do arise, our Furnace Repair - Miami team handles them directly. A maintenance visit typically runs $95 to $235, and it should include cleaning the burners, checking the heat exchanger for cracks, testing the safety switches, and measuring the airflow. Cold Harbour Heating and Air Miami performs this work carefully and gives you a written report of what was found, with photos where it matters. The technician is not paid on what he sells, so nothing gets inflated.
A Seasonal Check for a Coastal Climate
Miami’s humidity works on metal parts all year, even when the furnace never fires. We look for corrosion on electrical terminals and rust on the burner assembly – two of the most common issues we find in homes near Homestead and Florida City. For coastal properties, we also provide Furnace Repair in Miami Beach with the same thorough approach.
What Maintenance Should Cost, in Plain Numbers
You should pay between $95 and $235 for a standard furnace tune-up, and that price should be given to you before the work starts. If a company quotes less and then “finds” problems once they’re in the door, call someone else.

Heat Pump Repair
Heat Pump Repair covers the heating side of the split systems many Miami homes use instead of a standalone furnace. A heat pump moves warmth from outside air into your home, and when it stops doing that, the problem is usually a refrigerant leak, a failed reversing valve, a bad capacitor, or a defrost control board that quit. Cold Harbour Heating and Air Miami fixes all of these, with repair costs that typically fall in the $175 to $825 range. We test the refrigerant charge with digital gauges, not guesswork, and we explain what failed in plain English before we hand you a written price. Because a heat pump does double duty, the same technician who repairs the heating side can diagnose your AC as well.
Common Failures in Warm Climates
Valves and control boards wear faster in South Florida because the system cycles for cooling so much of the year. If your heat pump runs constantly but the air never gets warm, the reversing valve is a likely culprit.
Why Refrigerant Levels Matter Here
An undercharged heat pump works harder and freezes up, even when outdoor temperatures barely dip below 50. We measure the charge against the manufacturer’s specification and repair any leak before we add refrigerant.
Heating Repair
Heating Repair is the broad work of diagnosing and fixing any system that produces warmth in your home, whether that system is a furnace, a heat pump, a boiler, or a ductless unit. The first thing we do is listen – to what the system sounds like, to what you’ve noticed, and to what the thermostat is actually reporting. Then we test, using a multimeter on the electrical side and a combustion analyzer when a gas system is involved. Most repairs in Miami fall between $175 and $825, and that number is handed to you in writing before work begins. Cold Harbour Heating and Air Miami never charges overtime for a repair we diagnose on a cold night.
Diagnosis Before Recommendation
We don’t sell parts on a guess. A technician may spend 30 to 45 minutes pinpointing the failure, and that diagnostic work is covered by the free estimate we provide before any repair begins.
The Written Price Difference
The price we quote is the price you pay. No dispatch fee surprise, no “parts ended up costing more” call from the truck. Victor Mancini holds every technician to that standard, and it’s written on the estimate you sign.
Boiler Repair
Boiler Repair is the specialized service for homes that heat with hot water instead of forced air. Many older Miami homes and multi-unit buildings have boilers, and when a boiler fails, the signs are usually cold radiators, strange knocking sounds, or a pilot light that won’t stay lit. Common repairs we perform include replacing circulator pumps, flushing sediment from the system, fixing leaking pressure relief valves, and replacing faulty aquastats. Boiler repairs in Miami generally cost between $175 and $825, and we carry most common parts on the truck. Because boiler water can be dangerously hot and the system is under pressure, we recommend letting a trained professional handle any safety valve or pressure issue.
Radiator Systems in Older Homes
Coral Gables and Coconut Grove have a number of older homes with radiator heat, and those systems build up sediment that reduces efficiency. We flush the lines, bleed trapped air, and check the expansion tank on every boiler visit.
Pressure and Safety
A boiler that hits high pressure or leaks around the relief valve needs a professional look immediately. We test the valve, check the auto-fill, and verify the high-limit control is cutting out at the correct temperature.
Gas Furnace Repair
Gas Furnace Repair addresses the specific components that make gas heating work: igniters, flame sensors, gas valves, burners, and the safety chain that tells the system it’s safe to fire. If you smell gas or hear a clicking that never turns into a flame, shut the system off at the thermostat and call us. Most gas furnace repairs in Miami run from $175 to $825, and we repair all major brands including York, Daikin, Bryant, and American Standard. Cold Harbour Heating and Air Miami will test the heat exchanger for cracks and inspect the gas line connections at every furnace visit. Gas work is not a place for trial and error, and we never leave a system running without verifying clean, blue combustion.
Ignition Systems
Most modern furnaces use a hot surface igniter, a small ceramic part that glows to light the gas. These fail over time, and the replacement usually runs $150 to $280 parts and labor included, one of the most common repairs we perform from Miami Lakes to Aventura.
Gas Safety Checks
We use a combustion analyzer to verify carbon monoxide levels stay well below dangerous thresholds, and we check the flue pipe and draft inducer for proper venting. If the system can’t vent safely, we don’t leave it running, period.
Furnace Tune Up
A Furnace Tune Up is the annual service that catches problems while they’re still cheap. The best time in Miami is late fall, before the brief cold stretch that tends to hit in January. A tune-up runs $95 to $235 and takes about an hour. We clean the burners, test the igniter, check the gas pressure, inspect the heat exchanger, tighten electrical connections, and verify the thermostat is calibrated correctly. Cold Harbour Heating and Air Miami leaves you with a written report of what was tested and what condition it’s in. A furnace that’s maintained lasts years longer, and the tune-up keeps your manufacturer’s warranty valid in most cases.
The Budget-Saver Visit
Most emergency furnace failures we see in January saw a small warning sign back in October – a delayed ignition, a whine, a limit switch that tripped once. A tune-up catches those for $95 to $235 instead of the $400 to $800 repair they become.
What the Report Shows
We document the system’s amperage draw, temperature rise, and gas pressure at each visit. Two years of reports side by side show you exactly how the system is aging, and that’s information you can’t get from a no-show repair call.
Emergency Furnace Repair
Emergency Furnace Repair is what we do when a system dies on the coldest night of the year and you can’t wait until morning. Cold Harbour Heating and Air Miami answers the phone with a live person 24 hours a day, 7 days a week, no voicemail trees and no answering service that tells you someone will call back. Emergency repairs fall in the same $175 to $825 range as standard repairs, and we don’t charge an overtime premium for the lateness of the hour. The technician who arrives will carry igniters, flame sensors, capacitors, and control boards for the most common brands, including the York, Daikin, and Bryant systems we see throughout Miami-Dade County.
What Counts as an Emergency
No heat on a cold night, a gas smell near the furnace, a burning smell from the vents, or a system that trips the breaker repeatedly all justify a same-day call. These are not problems to sleep on, especially with children or elderly family in the house.
Same-Night Repairs We Can Usually Complete
A failed igniter, a dead flame sensor, or a run capacitor can typically be replaced the same visit. We carry the parts on the truck, and if we don’t have what you need, we’ll be straight with you about the timeline before we leave.
Brands We Service
Our technicians are trained to service nine major residential HVAC brands, and we keep a deep inventory of parts for the ones we see most in South Florida. York systems are common in Miami condo buildings, and we’re familiar with the specific control boards and gas valves those units use. Daikin units sit on a lot of rooftops in townhouse communities, and we stock their OEM igniters and flame sensors to avoid second-trip delays.
Bryant furnaces show up regularly in single-family neighborhoods near Fountainebleau and Kendale Lakes, and American Standard units run in many of the larger homes we service around Country Club and Doral. We also offer our Furnace Repair in Hialeah for homeowners in that area. Whether you have one of those brands or any other make, we can help. The Kingswell network trained our technicians to work by the same written standards across all of them.

AfterSigns You Need a Pro Right Now
- The furnace clicks but never fires. That repetitive clicking is the igniter trying and failing, which often points to a failing igniter or a clogged gas port. It’s a quick fix if caught early, and a headache if the system is allowed to crack the heat exchanger from repeated misfires.
- The system short cycles constantly. If the furnace fires up, shuts down, and repeats every few minutes, a limit switch is reading heat build-up or a flame sensor is dirty. Left alone, the motor and gas valve will take a beating and the repair bill climbs.
- You smell gas or a faint sulfur odor. Natural gas is odorless, and the rotten-egg smell is an additive meant to alert you. If you smell it near the furnace, call us immediately and shut the gas valve behind the unit if you can reach it safely.
- Warm air barely trickles from the vents. This usually means a failing blower motor or a clogged filter, but it can also indicate a crack in the heat exchanger allowing combustion air into the supply duct. Weak airflow in a furnace is never just an annoyance.
- Any noise beyond a low, steady hum. Banging, popping, or rattling when the furnace lights can mean delayed ignition or a cracked heat exchanger, both problems that get worse with every cycle. A furnace that sounds angry is a furnace that needs a professional before the next cold snap.
Our Process, Step by Step
We follow a written process on every visit, so nothing is left to chance and you know what’s happening at each step.

5. The guarantee is written down. Every repair includes the 365-Day Done Right Promise, written on the invoice. If the repair fails within that year, we come back and correct it at no charge. That’s from Victor Mancini, the owner, and it’s on paper.
How Much Does Furnace Repair Cost in Miami?
A typical furnace repair in Miami runs $175 to $825, depending on what failed. An igniter replacement in a York or Bryant furnace usually falls in the $150 to $280 range, parts and labor included. A flame sensor that needs cleaning or replacement runs $100 to $200. A control board, which is the brain of the furnace, can run $350 to $700 depending on the brand. A gas valve replacement lands between $250 and $500, and a heat exchanger replacement, which requires careful fitment and sealing, can push toward the $800 to $1,500 mark on some units, though the $825 top figure covers most of what we see. What affects the price is the part cost, which varies by brand, and the labor time to access and replace it. Furnaces packed into tight Miami attic spaces take longer than units in a garage. Avoid overpaying by asking for a written price before any work begins and a written guarantee on the repair. Our free estimate includes the diagnostic time and the written price, so you’ll never be surprised.
