In Plantation's hot-humid climate, an annual AC tune-up before cooling season is the minimum. Condensate drain lines should be flushed every 3 to 4 months during the cooling season in Broward County, since sustained humidity creates ideal conditions for algae growth that blocks the drain. Filters should be replaced every 30 to 45 days from May through September. A system that receives annual professional service plus regular filter changes will experience significantly fewer midseason failures than one that is only serviced reactively.

Furnace short cycling — turning on and off more frequently than normal — is most commonly caused by a clogged air filter, overheating from restricted airflow, an oversized furnace, or a failing flame sensor. Restricted airflow causes the heat exchanger to overheat, triggering the high-limit switch which shuts off the burners. Once cooled, the system restarts. An oversized furnace heats the space too quickly, satisfying the thermostat before completing a full burn cycle. Start by replacing the filter. If short cycling continues with a clean filter, a technician should check static pressure, heat exchanger temperature, flame sensor condition, and system sizing. Short cycling significantly accelerates heat exchanger wear.

Sudden furnace failure is most commonly caused by a tripped safety switch, a failed igniter, a blown control board fuse, or a gas supply interruption. Safety switches (high-limit, pressure, rollout) trip when abnormal conditions are detected and lock out the system until the underlying fault is corrected. Igniters fail suddenly in cold weather because thermal cycling stress fractures the element over time. Check the furnace power switch, circuit breaker, and thermostat batteries first. If a pressure switch or rollout limit is tripped, do not reset it repeatedly — it indicates an active problem. In Hot-Humid climates with extreme cold, emergency service is warranted when indoor temperatures will drop below 55°F.

The standard guidance is to replace a furnace when the repair cost exceeds 50 percent of the replacement cost, or when the system is over 15 years old and requires a major repair. Older systems face compounding failure risk — repairing one component does not prevent adjacent aged components from failing. Systems over 15 to 18 years old also operate significantly below current efficiency standards, creating an ongoing fuel cost penalty. Use the age-times-repair-cost formula: multiply the system age by the repair cost. If the result exceeds $5,000, replacement is typically the better financial decision. In Hot-Humid climates with high heating demand, the efficiency gain from a new system accelerates payback.

A banging or popping noise at furnace startup most commonly indicates delayed ignition — where unburned gas accumulates before igniting — or duct expansion from temperature changes. Delayed ignition is caused by dirty burners, a weak igniter, or low gas pressure that allows gas to build before combustion occurs. The resulting mini-explosion is the ignition of accumulated gas. Duct banging is caused by thermal expansion of sheet metal in undersized or uninsulated ducts. A banging noise at ignition is a safety concern — schedule service promptly. Repeatedly starting a furnace with delayed ignition can crack the heat exchanger. Duct banging typically improves with filter replacement or duct insulation.

A cracked heat exchanger cannot be repaired and should not be operated — the only safe resolutions are heat exchanger replacement or full furnace replacement. The heat exchanger separates combustion gases including carbon monoxide from the circulated air supply. A crack allows flue gases to enter the airstream. Welding or sealing a cracked heat exchanger is not an accepted repair — it will not hold under repeated thermal cycling and CO risk remains. If a technician diagnoses a cracked heat exchanger, get a second opinion confirming the crack location and extent before deciding between component replacement and full system replacement. For systems over 15 years old, full replacement is almost always the more economical decision.

Furnace efficiency declines due to combustion deposit buildup on burners and heat exchanger surfaces, blower motor wear, increased distribution losses, and gradual heat exchanger surface deterioration. Combustion deposits reduce heat transfer efficiency — the same quantity of fuel produces less usable heat. Blower motor bearings wear and draw more amperage for the same airflow. Older ductwork accumulates leaks that divert conditioned air to unconditioned spaces. The national average efficiency degradation for an unmaintained furnace is 1 to 5 percent per year. A 20-year-old furnace rated at 80% AFUE may actually operate at 60 to 65% AFUE in service — equivalent to burning 15 to 20 cents of every fuel dollar for no useful heat.

A primarily yellow or orange furnace flame indicates incomplete combustion and is not safe to operate without diagnosis — it signals a burner problem that increases carbon monoxide production. A healthy gas burner produces a steady blue flame with a small yellow tip. Yellow flame results from insufficient air-to-fuel mixing, dirty burner ports, low gas pressure, or a misaligned burner. Incomplete combustion generates carbon monoxide rather than carbon dioxide. Do not continue operating a furnace with a consistently yellow flame. Turn the system off and schedule service. Verify CO detectors are functioning on all levels of the home. This applies to natural gas, propane, and oil systems.

Furnace repair costs range from $150 to $1,500 depending on the component. Minor repairs like igniter or flame sensor replacement run $150 to $400. Major repairs like heat exchanger or control board replacement run $600 to $1,500. Labor accounts for 40 to 60 percent of repair cost in most markets. Emergency or weekend service adds 25 to 50 percent to standard rates. Part availability and system age also affect total cost. Get a written diagnostic quote before authorizing any repair over $300. Compare the repair cost to 10 to 15 percent of a replacement system cost — if repair exceeds that threshold and the system is over 15 years old, a replacement estimate is warranted.

The most common furnace repairs are igniter replacement, flame sensor cleaning or replacement, inducer motor replacement, and pressure switch diagnosis. In Hot-Humid climates with long or intense heating seasons, igniters and inducer motors cycle more frequently — accelerating wear. High-humidity climates see more corrosion-related failures on heat exchangers and secondary heat exchangers in condensing furnaces. In Very Cold and Freeze-Thaw climates (HZ-07, HZ-11), combustion air intake freeze is an additional failure mode not seen in milder regions — confirm the intake is routed and protected correctly when scheduling fall maintenance.

Increased furnace cycling in early fall or spring is often related to mild outdoor temperatures — the system overshoots setpoint quickly when the temperature differential is small. During mild weather, the outdoor-to-indoor temperature differential is small, meaning the furnace delivers more heat per cycle than the space needs. This is a sizing and weather interaction, not a system fault. If short cycling occurs during deep winter, it indicates overheating, flame sensor, or airflow problems. Seasonal short cycling in mild temperatures typically resolves as cold weather deepens. Persistent short cycling across all conditions — or short cycling during peak cold — requires diagnostic service.

A brief burning odor when a furnace runs for the first time in fall is typically dust burning off the heat exchanger and is normal. A persistent burning smell, plastic odor, or burning that recurs throughout the season is not normal. Dust that settles on the heat exchanger during the off-season combusts on first heat cycles, producing a brief smoky odor that clears within one to two cycles. Persistent odors indicate wiring insulation burning, a blower motor overheating, or a foreign object in the system. If the odor clears after 1 to 2 heating cycles, no action is needed. If the odor persists, smells like melting plastic, or is accompanied by visible smoke, shut off the furnace and call for service.
