Corrosion near the coast
Salt in the air attacks outdoor coils and connections. A heat pump near the beaches or the river can fail earlier than an inland one.
Heat pump repair in Jacksonville, FL
In Jacksonville most homes cool and heat with a heat pump, so when it fails you may lose the AC in summer or the heat on a cold night. Jacksonville winters are colder than Orlando's, with real freezing nights, so heating mode and the electric backup heat matter here.
Common problems are a failed capacitor or contactor, a stuck reversing valve, a defrost or control issue, a fan motor failure and refrigerant leaks. Emergency service is available 24/7.
The price in plain numbers
Most Jacksonville heat pump repairs run about $250 to $550, with major repairs running $1,200 to $2,800. A diagnostic service call is typically $69 to $89.
Heat pumps cost slightly more to repair than a plain AC because of extra parts, such as the reversing valve and defrost control. See our heat pump repair pricing guide.
Examples of our work
How a heat pump works, simply
A heat pump moves heat. In summer it takes heat out of your home and sends it outside, like an air conditioner.
In winter a reversing valve flips the direction, so the system draws heat from the outdoor air and delivers it inside. Electric heat strips in the indoor unit add heat when the air outside is too cold for the heat pump to keep up.
In Jacksonville that matters more than in Central Florida, because freezing nights happen most winters. When temperatures drop, the heat strips run, and if they have failed, you find out on the coldest morning.
Jacksonville specific heat pump problems
Reversing valves and defrost controls
Heat pumps in Florida cycle many hours a year, and the valve and defrost parts wear. Signs are cool air in heating mode or ice that stays on the outdoor unit.
Failed heat strips
Strips can burn out in spring and go unnoticed until winter. We test them on fall checkups.
Drain clogs and surges
Humidity clogs the drain, and storms damage capacitors and boards.
Signs your heat pump needs repair
Cool air in heating mode
A stuck reversing valve, low refrigerant, a defrost problem or failed heat strips. Check that the thermostat is set to heat first.
Not cooling in summer
A failed capacitor or contactor, a dirty or corroded coil, a leak or a blower problem.
Ice that stays on the outdoor unit
A defrost control or sensor problem, or restricted airflow. Turn it off and call.
Water around the indoor unit
Usually a clogged condensate drain. Turn the system off and call.
The unit hums but the fan does not turn
Often a failed capacitor. Do not keep forcing it to start.
Higher bills
The system is working harder than it should, often from low refrigerant, dirty coils or heat strips running too much.
How a heat pump repair visit goes
- We start with the mode that failed. Cooling and heating problems point at different parts, so we ask which one you noticed and when.
- We verify the settings and power. Thermostat mode, filter, breaker and airflow.
- We run the system and measure it. Meter readings on the electrical parts, refrigerant pressures, temperature drop across the coil, the reversing valve, defrost cycle, heat strips, motors and the drain.
- We inspect for salt damage. The coil, the cabinet and the connections, since corrosion causes repeat failures.
- We find the reason for the failure. A failed part is often a symptom. If a motor is pulling too much current, replacing only the capacitor would not last.
- You get options and a price. Before work begins, with a replacement price too if the system is old and the repair is large.
- We repair and test it. We confirm it works in the mode that failed before we leave.

A freezing night plan for Jacksonville heat pumps
When the forecast shows a freeze, a few steps help your heat pump and your bill.
Before the cold arrives
Make sure the filter is clean, the outdoor unit is clear of leaves and the thermostat is set to heat. Do not turn the thermostat way up all at once, since that triggers the electric strips and a surge in power use.
During the freeze
Set a steady temperature and leave it. If you see a thin film of frost on the outdoor unit, that is normal and the defrost cycle handles it.
Ice that builds thick and stays is not normal. Open cabinets under sinks on exterior walls if pipes are at risk.
If the heat quits
Switch the thermostat to emergency heat only if the system has that setting and the problem is the outdoor unit. Emergency heat runs the electric strips alone and costs more to run, so use it as a bridge until we arrive.
Call us right away, and tell us what the thermostat shows.
Why Jacksonville heat strips matter, and what is normal on your bill
On the coldest mornings, the heat pump alone cannot keep up, so electric strips add heat. They are efficient at nothing except being reliable, and they use a lot of electricity.
That is why a cold week can raise a bill sharply. A few extra dollars a day on a freezing week is normal.
A bill that jumps for weeks without a cold spell suggests the strips are running too much, which can mean a heat pump problem. A technician can check whether the outdoor unit is delivering heat the way it should.
Repair or replace?
We weigh these together:
- The compressor fails on a system over 10 years old.
- The reversing valve fails on a system over 12 years old.
- The coil is corroded or leaking.
- Two or more major repairs in the last two years.
- The system uses R-22 refrigerant, which is no longer produced.
- The repair would cost a large share of a replacement and the system is old.
A young system with an isolated problem is usually worth repairing. If you decide to replace, JEA lists a $200 rebate for ENERGY STAR certified heat pumps.
Test heating mode in the fall
Once a year, in October or November, switch the thermostat to heat on a cool morning and let the system run for ten to fifteen minutes. Check that warm air comes out and the outdoor fan runs.
A brief dusty smell when the heat strips first warm up is normal. If the air stays cool or nothing happens, call us then, not on the first freezing night.
What to leave to a technician
You can change the filter and keep the outdoor unit clear of plants and debris. Do not open refrigerant lines, replace capacitors or bypass safety controls.
Refrigerant work needs federal certification, and capacitors hold a charge even with the power off.

Common questions
How much does heat pump repair cost in Jacksonville?
Most repairs run about $250 to $550. Major repairs run $1,200 to $2,800. The diagnostic call is typically $69 to $89.
Why is my heat pump blowing cool air in winter?
Check that the thermostat is set to heat. If it is, a stuck reversing valve, low refrigerant, a defrost issue or failed heat strips could be the cause. Call us.
How cold does Jacksonville get, and will my heat pump keep up?
Jacksonville has a few freezing nights most winters. A heat pump handles most days, and electric heat strips cover the coldest mornings.
How long do heat pumps last in Jacksonville?
Often 10 to 15 years. Salt air near the coast can shorten that, and yearly service helps.
What is auxiliary heat?
Electric heat strips that add warmth when the heat pump alone cannot keep up. If they run constantly, bills climb and something may be wrong.
Do you offer emergency heat pump repair?
Yes, 24/7.
Do you repair all brands?
