We’ve been serving Conway since 2003 as part of the Kingswell network of independently owned HVAC businesses, offering Conway AC Repair and heating services, with dispatch and scheduling coordinated from our Miami office and crews working Conway streets daily. The lakeside humidity here is not a footnote, it’s the main character in most furnace stories we encounter. That persistent moisture off the Conway Lakes chain corrodes burners, degrades heat exchangers, and creates condensation patterns in flue components that inland Orange County technicians rarely recognize. When your furnace won’t light, short-cycles, or throws a pressure switch code, you want someone who has already traced that exact symptom through a dozen Conway attics.
Why Coldharbour Heating & Air Is Conway’s Preferred Furnace Repair Company
Conway homeowners have long memories, and they talk. We earn our calls through repeat customers in neighborhoods like the original Conway Isles plat, the ranch streets off Curry Ford Road, and the post-war blocks near Gatlin Avenue. They mention the same things: we showed up in the window promised, we handed them a written price before touching a tool, and when a repair failed six months later, we came back and fixed it at no charge under our 365-Day Done Right Promise.
Our response time to Conway averages under two hours for no-heat emergencies during heating season, because our technicians start from staging points throughout Orange County rather than a single distant depot. Every technician is background-checked, uniformed, and trained on nine major residential brands, so the person who knocks on your door can actually work on whatever system is already installed, whether it’s a 1990s Rheem, a newer Daikin, or anything in between.
We also understand the local building stock. Conway was one of Orlando’s earliest post-WWII suburban expansions, and the dominant housing type, a 1950s-1970s slab-on-grade ranch with original ductwork through an unconditioned attic, creates predictable failure modes. Many of these systems have been replaced multiple times while the ductwork stayed original, undersized, and deteriorating. That matters because even a brand-new furnace will short-cycle, overheat, and fail prematurely if it’s pushing against static pressure it was never designed to handle.
Gas Furnace Repair in Conway
Gas Furnace Repair in Conway addresses the specific ways natural gas heating systems fail in this lakeside microclimate, from corroded burners and intermittent ignitors to heat exchangers degraded by years of humidity cycling. Most gas furnace repairs in Conway fall between $150-$700, with simpler fixes like ignitor or flame sensor replacement toward the lower end and heat exchanger or gas valve work toward the upper. We always provide a written price before any work begins, and every repair carries our 365-Day Done Right Promise in writing.
Heat Exchanger and Flue Condensate Issues
Conway’s position inside the Conway Lakes chain keeps overnight dewpoints higher than inland Orange County, so furnace failures here often present as heat exchanger and flue-condensate problems from equipment that ran in near-constant humidity rather than simple ignition faults. We inspect heat exchangers with cameras and combustion analyzers, and if we find corrosion or cracking, we explain exactly what we see and why replacement is the only safe path. A cracked heat exchanger can leak carbon monoxide into your living space. We don’t negotiate on that.
Gas Valve and Burner Assembly Restoration
Gas valves in Conway furnaces can stick or leak after years of moisture exposure, and burner ports clog with corrosion flakes that disrupt the flame pattern. We clean or replace burner assemblies, test gas pressure at the manifold, and verify proper flame rollout. The work takes two to three hours in most Conway ranch homes, and we test every safety switch before we leave.
Furnace Tune Up in Conway
Furnace Tune Up in Conway is preventive maintenance designed for the specific stress this lakeside climate places on heating equipment, priced at $80-$200 and completed in about 90 minutes. We recommend a tune-up every fall before the first cold snap, because Conway’s humidity doesn’t take winters off, it just shifts patterns. A proper tune-up catches the corrosion, calibration drift, and airflow restrictions that become emergency failures on the first night you actually need heat.
Combustion Analysis and Safety Inspection
We test flue gas composition with a combustion analyzer to confirm your furnace is burning efficiently and venting safely. In Conway’s older homes, we often find draft inducers working harder than specified because original flue liners have deteriorated or been modified. We measure temperature rise across the heat exchanger and compare it to manufacturer specifications. If it’s off, we find out why before it becomes a no-heat call at midnight.
Electrical Component and Blower Testing
Capacitors weaken, contactors pit, and blower motors draw excess amperage when they’re fighting restricted ductwork. We test every electrical component under load, measure static pressure across the system, and check your filter and evaporator coil condition. In Conway’s unconditioned attics, where summer temperatures regularly exceed 130°F, these components age faster than the manufacturer predicted.
Trusted Brands We Service in Conway
Our Furnace Repair technicians carry diagnostic tools and common parts for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard systems. For Conway customers, this means faster resolution without waiting for a parts run to a distant warehouse. We regularly stock ignitors, flame sensors, blower motors, and control boards for Rheem and York units, which remain common in the 1980s and 1990s construction around Conway Isles. Daikin and Bryant parts availability has improved significantly, and we keep select heat exchanger and gas valve assemblies on hand for same-day completion when the diagnosis supports it. If your system is older or less common, we’ll tell you honestly whether repair makes sense or if the parts lead time pushes toward replacement.
Common Furnace Repair Problems We See in Conway Homes
- Short-cycling from restricted original ductwork. The 1950s-1970s slab-on-grade ranch homes that define Conway were built with undersized duct runs through unconditioned attics. Decades of heat cycling have degraded that ductwork, raising static pressure until the furnace overheats and shuts off on high limit. Homeowners often blame the furnace when the real problem is the path the air must travel.
- Corroded ignitors and burners from lakeside humidity. Persistent moisture from the Conway Lakes chain corrodes metal furnace components faster than in drier inland Orange County suburbs. We see intermittent ignition and nuisance lockouts that clear temporarily but return until the affected parts are replaced.
- Secondary drain pan float switches causing nuisance shutdowns. The elevated dewpoint around Lake Conway, Little Lake Conway, and Lake Gatlin keeps evaporator coils and drain pans working overtime. Float switches in secondary drain pans trip and kill power to the entire system, including the furnace, a pattern we call the “lake-side shutdown” that inland competitors rarely diagnose correctly.
- Blower motor and capacitor failure from long run cycles. Single-zone systems in unbalanced older floor plans force the furnace to run extended cycles to reach distant rooms. That stresses blower motors and capacitors beyond their design duty, and we see premature failures especially in homes where the thermostat was relocated without recalibrating the system balance.
Pricing for Furnace Repair in Conway, FL
Most furnace repairs in Conway run $150-$700, with the final figure depending on which component failed and how accessible it is in your specific installation. A typical ignitor replacement runs $150-$280, parts and labor included. Flame sensor cleaning or replacement falls in a similar range. Blower motor repairs or replacements trend $350-$550. Heat exchanger work or gas valve replacement reaches the upper end of our range, and we always explain why before you decide.

FAQs About Furnace Repair in Conway
Short-cycling after replacement usually means the new furnace was matched to the old ductwork without a proper load calculation and static pressure test. Conway’s original 1950s-1970s ranch homes have undersized attic duct runs that restrict airflow; a modern furnace with a higher efficient blower motor actually detects that restriction faster and shuts down on high limit. We measure static pressure and duct capacity before recommending any equipment change, because a furnace is only as good as the path the air travels. Call (817) 402-2972 for a diagnostic that includes duct assessment.
Yes. The Conway Lakes chain, including Lake Conway, Little Lake Conway, and Lake Gatlin, creates a localized humidity microclimate with overnight dewpoints measurably higher than inland Orange County. That moisture corrodes burners, ignitors, and flue components faster, and it creates condensation patterns in heat exchangers that accelerate metal fatigue. We see heat exchanger and flue-condensate failures in Conway that are rare just a few miles west. Our technicians factor this into every inspection and component recommendation.
Once yearly, every fall, before the first sustained cold period. Conway’s 10-month cooling season means your furnace sits idle through long humid stretches, and that idle time allows corrosion to progress unnoticed. A fall tune-up at $80-$200 catches degraded components, verifies combustion safety, and confirms your system will start reliably when you need it. We also check condensate drains and float switches, because the lakeside humidity that affects cooling season creates year-round moisture management challenges.
A “lake-side shutdown” is our term for the pattern where a tripped secondary drain pan float switch kills power to the entire HVAC system, including the furnace, due to condensate overflow from the elevated dewpoint around the Conway Lakes. The evaporator coil ices or the drain pan fills, the float switch trips, and the homeowner calls for a no-heat diagnosis. Inland technicians often replace control boards or ignitors without addressing the root moisture issue, and the callback loop continues. We trace the actual water path, clear or replace drain lines, and verify float switch function so the furnace stays running.
Often, yes. Many Conway ranch homes still have original electrical panels or early replacement panels that lack the capacity or breaker spaces for modern furnace electronics, variable-speed blowers, and associated safety circuits. We inspect your panel as part of any replacement quote and coordinate licensed electrical work when needed. Installing a high-efficiency furnace on an inadequate panel creates fire risk and code violations, and we won’t proceed without addressing it. The written price we provide includes any necessary electrical upgrades, with no surprises after work begins.
