Emergency Heat Pump Repair in Greater Jacksonville

A heat pump is the only heating and cooling system most Greater Jacksonville homes have, so when it fails there is no backup. In January that means a cold house and electric strips running up the bill. In August it means no cooling at all. Fouraker Mechanical answers heat pump emergencies around the clock, targets same-day service across Nassau County, Jacksonville, Baker County, and Baldwin, and repairs every major brand from a stocked truck.

What We Offer

Heat pump emergencies in winter

Cold snaps in Greater Jacksonville are short but sharp, and the heat pump failures show up on the first cold night.

• No heat at all: The outdoor unit is not running. Usually a capacitor, contactor, or a tripped breaker. Sometimes a failed compressor.
• Cold air in heat mode: The reversing valve did not switch, or the system is stuck in defrost. The unit runs but blows cool air.
• Only the strips are working: The thermostat shows Aux or Emergency Heat constantly. The house is warm, but the heat pump has failed and the bill is climbing fast.
• Outdoor unit frozen solid: A failing defrost board, a bad sensor, or low refrigerant. A light frost is normal; a block of ice shuts the system down.
• Breaker trips in heat mode: The heat strips draw heavy current. A shorted element, a failed sequencer, or a weak breaker trips it.

If you have no heat and the outside temperature is near freezing, switch the thermostat to Emergency Heat so the strips carry the house until we arrive. It is expensive, but it is safe for a night.

Heat pump emergencies in summer

In cooling mode a heat pump fails the same way a standard air conditioner does, and the fixes are the same.

• Not cooling: Capacitor, contactor, clogged drain tripping the float switch, or a refrigerant leak.
• Frozen indoor coil: Restricted airflow or low refrigerant. Turn the system off and let it thaw before the technician arrives.
• Short cycling: A failing control board, thermostat, or an oversized unit that never runs long enough.
• Outdoor fan stopped: The compressor overheats within minutes and cuts out on its safety. Shut the system off.

Our emergency AC repair page covers the summer checks you can do yourself in two minutes before you call.

What to check before you call

These quick checks resolve some no-heat calls on their own and help us diagnose the rest faster.

• Thermostat mode: Confirm it is set to Heat, not Cool or Off, and the set point is above the room temperature.
• Breaker panel: Heat pumps usually have two breakers, one for the outdoor unit and one for the air handler and strips. Check both. Reset once only.
• Outdoor disconnect: Make sure the gray box near the outdoor unit has not been switched off or had its pull-out removed.
• Filter: A clogged filter in heat mode can trip the high-limit switch on the strips. Replace it if it is gray.
• Outdoor unit: Note whether the fan is spinning, whether the unit is iced over, and any sounds. Tell us when you call.

How emergency heat pump service works

Here is what happens from the moment you call.

• A person answers: 24 hours a day. We ask what the system is doing and tell you honestly whether it needs a truck now or can wait until morning.
• Nearest technician dispatched: Our techs live across the region, from Fernandina Beach to Macclenny, so response times are shorter than a single Jacksonville shop can offer.
• Diagnosis, then a written price: The technician finds the fault, shows you the failed part, and gives you the repair price before starting.
• Repair from the truck: Reversing valve solenoids, defrost boards, sensors, capacitors, contactors, sequencers, and refrigerant for the common brands ride on the truck.

Repair or replace an older heat pump

We fix heat pumps for a living, but there is a point where another repair is the wrong use of your money.

The usual signals are a system 12 to 15 years old, a failed compressor, a corroded coil on a coastal unit, an R-22 refrigerant leak, or a second major repair in the same year. When we hit one of those, we give you both numbers in writing: the repair and a properly sized replacement with FTL Finance options. Goodman is our primary install brand, with Daikin, Carrier, and Trane available. The choice stays yours.
