About This Service
Heating Services in Jacksonville & Northeast Florida
Nearly every home in this region uses a heat pump as its primary heating and cooling system. Unlike a furnace that burns fuel, a heat pump transfers heat using a refrigeration cycle — and Florida heating problems follow specific patterns that differ from those in the north. Diagnosing the issue correctly on the first visit requires a technician who works on heat pump systems in this climate daily. All Set technicians do exactly that.
Service Scope
What's Included in Heating Repair & Maintenance
Typical heating repair cost: $200–$1,800 depending on the failed component and system type.
Common Symptoms
What Your Heat Pump Is Telling You
Nearly every home in Jacksonville and Clay County heats with a heat pump, not a furnace — and Florida heat pump failures follow recognizable patterns. Knowing which symptoms point to which failure helps the technician arrive prepared and fix it on the first visit.
Running but Not Heating
When the system runs and moves air but produces no warmth, possible causes include a reversing-valve or control issue, low refrigerant, auxiliary-heat failure, or a thermostat problem. The repair path and timing depend on diagnosis and parts availability.
Blowing Cold Air in Heat Mode
Thermostat on heat, fan running, but vents blow cool or room-temp air for more than 30 minutes. Usually a reversing valve issue, a heat-mode refrigerant problem, or a defrost cycle running abnormally long.
Stuck in Emergency Heat
If the thermostat switched to emergency heat on its own, the system detected a problem with the outdoor unit. Emergency heat costs 2–3× more to run — leave it on, but call for a diagnostic.
Unusual Noises in Heating Mode
Grinding or screeching usually means a fan motor bearing. Rattling or banging from the outdoor unit points to the compressor. Hissing or bubbling suggests a refrigerant issue that shows up in heat mode first.
Running Constantly, Never Reaching Temp
If the system runs non-stop at night while it's 45° outside and only 62° inside, that's not a capacity limit — that's a heat-mode problem worth diagnosing.
No Heat at All, Won't Turn On
Complete failure to operate in any mode often involves an electrical or control issue, such as a failed capacitor, tripped breaker, contactor, thermostat, or safety switch. Repair timing depends on the diagnosis and parts availability.

Common Questions
Questions Homeowners Ask About Heating Service
Yes. Almost every home with central AC in this area has a heat pump, which provides both cooling and heating by reversing its refrigeration cycle. A heat pump isn't a separate system added on top of an AC unit — it's one system that handles both. If your home has central AC, it likely heats your home the same way.
Heat pumps periodically run a defrost cycle lasting 10–15 minutes, temporarily blowing cool or lukewarm air. This is normal. If the system has been blowing cool air for more than 30 minutes, or the outdoor unit is completely covered in ice, that's a problem worth diagnosing. See common symptoms →
