The HVAC section of the 4-point inspection is typically the most straightforward of the four systems — but it still has a few areas that trip up homeowners, particularly the questions about central heat. In Southwest Florida, where air conditioning runs nearly year-round and heating is an afterthought for most people, it is easy to overlook the fact that insurance companies still require a functioning central heat source as a condition of coverage.
A — Central AC and Central Heat
The first two questions on this section are simple yes-or-no checkboxes: does the home have central air conditioning, and does the home have central heat? For most homes in the Cape Coral, Fort Myers, and Naples area, the answer to central AC is going to be yes — it would be unusual for a home in Southwest Florida to not have central air conditioning, and the absence of it would raise questions for the underwriter.
Central heat is where the confusion starts. Many homeowners in this part of Florida have never once turned on their heat. Some do not even realize their system has it. But in most cases, if you have a central air conditioning system with an air handler, there is a heat strip or heat pump built into that system. That counts as central heat. The inspector will verify that it is present and functional. If your system does not have a heat source at all — which is uncommon but not unheard of — that will be noted, and it may create a coverage issue depending on the carrier.
B — “If not central heat, indicate primary heat source and fuel type”
This line only comes into play if the answer to central heat is “No.” If the home does not have a central heating system, the inspector documents whatever the primary heat source is — a wall-mounted gas heater, a wood-burning fireplace, a space heater — along with the fuel type. This matters because not all heat sources are treated equally by insurance companies. A permanently installed gas wall heater is viewed very differently from a portable electric space heater plugged into a bedroom outlet. The further you get from a central, permanently installed system, the more likely the carrier is to have concerns.
C — Working Order and Last Service Date
The form asks whether the heating, ventilation, and air conditioning systems are in good working order — yes or no. If the answer is no, the inspector must explain. This is a visual assessment, not a performance test — the inspector is not running your system through a full diagnostic. They are checking for visible signs that the system is functional, not leaking, not showing signs of significant corrosion or deterioration, and appears to have been maintained. The date of last HVAC servicing or inspection is also recorded here. If your system has a service sticker from an HVAC company showing a recent maintenance visit, the inspector will note that date. If there is no sticker and you do not have a recent service invoice available, this field may be left blank or noted as unknown. Having your most recent HVAC service invoice on hand at the time of inspection can fill this gap.

D — Hazards Present
The HVAC hazards section asks a series of targeted questions, each aimed at a specific risk the insurance company wants to know about.
The first question asks whether a wood-burning stove or central gas fireplace is present that was not professionally installed. The emphasis on “not professionally installed” is the key. A properly installed fireplace or wood stove that was permitted and inspected is not a problem. One that was installed by a homeowner or a handyman without permits, without proper clearances, or without a code-compliant flue and venting system is a fire risk, and it will be flagged.
The next two questions ask whether a space heater is used as the primary heat source and whether that source is portable. This goes back to the central heat question above. If the home’s primary method of heating is a portable electric space heater, the insurance company is going to have concerns. Portable heaters are one of the leading causes of residential fires in the United States, and a home that relies on one as its primary heat source represents a materially higher risk to the carrier. This is another reason why confirming that your central system has a functioning heat strip or heat pump matters — it takes this entire line of questioning off the table.
The final question in this section asks whether the air handler, condensate line, or drain pan shows any signs of blockage or leakage, including water damage to the surrounding area. In Florida’s humid climate, condensate lines clog regularly if they are not maintained, and when they do, water backs up into the drain pan and eventually overflows. That overflow causes water damage to ceilings, walls, floors, and insulation — and water damage claims are exactly what insurance companies are trying to avoid. The inspector will look at the area around your air handler for staining, discoloration, warped materials, or active moisture. If your air handler is in the attic, any signs of water damage on the ceiling below it will also be noted. A clogged condensate line is a cheap and easy fix, but the water damage it causes if left unaddressed is not.

E — Supplemental Information
This section records the age of the HVAC system, the year it was last updated, and requires photographs of the equipment including the dated manufacturer’s data plate. The data plate is how the inspector determines the age of the system — it contains the manufacturer, model number, serial number, and date of manufacture. Some data plates are clearly labeled with a manufacture date. Others encode the date within the serial number, which an experienced inspector knows how to decode for all the major brands.
Most central HVAC systems in Florida have a useful life of roughly 15 to 20 years. Systems approaching or exceeding that range will be noted, and carriers may view them as higher risk — but age alone does not automatically result in an Unsatisfactory rating. A well-maintained 18-year-old system that shows no signs of leaks, corrosion, or water damage and has a documented service history is in a different category than a neglected 12-year-old system surrounded by water stains. The inspector documents what they observe, and the underwriter makes the call.
If your HVAC system has been replaced or significantly updated, having the permit, invoice, or receipt from that work available at the time of inspection ensures that the age recorded on the form reflects the current equipment rather than the original installation.
