Your furnace is cycling on and off, making sounds it shouldn't, or it's just not producing heat. Maybe there's a strange smell when it runs, or the pilot light won't stay lit. You've probably tried resetting the system or checking the thermostat. When that doesn't work, it's time to call a licensed technician. Baez & Son diagnoses and repairs furnaces across St. Cloud FL the same day you call.

If your furnace stopped working, is running but not heating, or is making sounds it never made before, we can help. A certified technician inspects your full system, identifies the root cause, and walks you through your repair options before any work starts. Most heating system repairs are completed the same day when parts are available.
Osceola County cold snaps arrive without much warning. A furnace that seemed fine in October can fail by December. Whether you are a homeowner in St. Cloud or a property manager with tenants without heat, we dispatch the same day you call and charge exactly what we quote.

If your gas furnace won't ignite, keeps shutting off before the house warms up, or is producing weak heat, the problem is usually in the igniter, flame sensor, gas valve, or burners. Our technician checks each one, explains what failed and why, and repairs it before leaving. Every gas heating repair includes a heat exchanger inspection for cracks that can allow carbon monoxide to enter your living space.
Gas furnaces are common in older St. Cloud neighborhoods built before dual-fuel systems became the standard. If your system is more than ten years old and showing any of these symptoms, a same-day diagnosis is the right first step.

If your electric furnace is blowing cold air, tripping breakers, or showing no heat output at all, the problem is likely in the heating elements, sequencers, or electrical connections. Our technician tests each component, identifies the failure, and gives you a clear recommendation on whether repair or replacement makes more sense given your system's age and condition.
Electric furnaces and heat strip systems are standard in Harmony and newer Osceola County subdivisions. If you are not sure whether you have a gas or electric heating system, that is fine. Our technician identifies your setup on arrival and diagnoses from there.

If your furnace is over 15 years old, has needed repeated repairs in the last two seasons, or has a cracked heat exchanger, replacement is likely the smarter financial decision. Our technician gives you an honest assessment before any work is recommended. When repair costs approach half the value of a new system, we say so. We size the replacement unit correctly for your space using a proper load calculation. No overselling on capacity.
Older St. Cloud and Polk County homes are still running heating systems well past their service life. A heating system replacement now, before a full failure, gives you control over the timing and the cost.

If you are replacing an aging system before it fails, adding heat to a new space, or building new construction, a properly sized installation makes the difference between a system that performs and one that runs up your energy bill. Our technicians size every unit to the space using a proper load calculation. Installation is completed by our licensed team under CAC#1823925 and CMC#1251747. We test the system fully before the job is closed out.
New construction in Narcoossee and surrounding Osceola County communities is driving demand for first-time heating system installations. Whether it is a single-family home or a commercial space, we size it right and install it right the first time.

Service call fees in the St. Cloud area typically cover the diagnostic visit and inspection. If we proceed with the repair, that fee is applied toward the total cost. We tell you what the visit costs before we come out and what the repair costs before we start. No surprises on the invoice.
The three most common causes we see are igniter failure, a dirty or failed flame sensor, and blower motor problems. An igniter that won't spark prevents the system from starting. A dirty flame sensor shuts the furnace off after a few seconds. A failing blower motor runs but moves little to no air through your vents. All three are diagnosable and repairable in a single visit in most cases.
Call a licensed HVAC contractor with same-day availability. Baez & Son dispatches seven days a week, including weekends and holidays. We are veteran-owned, licensed under CAC#1823925 and CMC#1251747, and we charge what we quote before work begins.
In most cases, standard homeowners insurance does not cover furnace repairs caused by normal wear and tear. If the damage resulted from a sudden covered event such as a power surge or fire, your policy may apply. Check your policy details or contact your insurance provider directly. We can document the failure and provide an itemized invoice if your insurer requires it.
The heat exchanger and the blower motor are typically the highest-cost repairs. A cracked heat exchanger is a safety concern and often costs more to replace than the remaining value of an older system. When a single repair approaches 50 percent of what a new system costs, we tell you. Replacement is sometimes the more honest recommendation.
Most repairs are completed in one to three hours in a single visit when parts are available. If a specific part needs to be ordered, we schedule a follow-up as quickly as possible. We let you know before we leave exactly what was done and what to expect next.
Most gas furnaces last 15 to 20 years. Electric furnaces can run slightly longer. In Florida, furnaces get less use than in colder climates, but that doesn't mean they last indefinitely. A system that sits idle most of the year still degrades. Seals dry out, components corrode, and ignition systems that worked fine in November don't always survive another season. If your furnace is over 15 years old, a diagnostic inspection tells you where it actually stands and whether repair or replacement makes more sense.
The $5,000 rule gives you a quick way to decide between repair and replacement. Multiply the age of the furnace by the estimated repair cost. If that number exceeds $5,000, replacement is usually the smarter investment. A 12-year-old furnace facing a $500 igniter repair scores $6,000, which tips toward replacement. A 5-year-old system with the same repair scores $2,500, which is clearly worth fixing. Baez & Son walks you through this calculation on every major repair call.
If replacement is the right call but the cost is a concern, Baez & Son offers financing options that let you spread the cost over time. We can also give you an honest assessment of whether a repair will buy you another season or two while you plan for replacement. We never recommend a repair we do not believe in just to generate a service call, and we never push a replacement you do not need.
