Heat Pump Repair in St. Johns County & Jacksonville

In Northeast Florida the heat pump is the whole system. It cools your home for most of the year and heats it through our short, sharp winters, so it wears harder than one in a colder climate. Our technicians find the actual cause, explain it in plain language, and give you a written price before any work starts.

Signs Your Heat Pump Needs Repair

Call us if you notice any of these:

  • Cool or lukewarm air in heat mode – often a reversing valve, a refrigerant problem, or a failed outdoor fan.
  • The “Aux” or “Emergency Heat” light stays on – your backup electric heat strips are doing the heat pump’s job. The house stays warm, but the power bill climbs fast.
  • Ice that doesn’t clear – light frost on the outdoor coil is normal and the defrost cycle melts it. A thick block of ice, or ice that stays for hours, is not.
  • It won’t switch between heating and cooling – usually the reversing valve, its solenoid, or the thermostat.
  • Short cycling – the system turns on and off every few minutes.
  • New noises – grinding, rattling, loud clicking, or a hiss from the outdoor unit.
  • A sudden jump in your electric bill with no change in how you use the system.

What We Check

A heat pump repair starts with finding the real cause, not just the symptom.

  • Refrigerant charge and leak testing – see Refrigerant Leak Repair
  • Reversing valve and solenoid operation in heating and cooling mode
  • Defrost control board, sensors, and timer
  • Compressor, capacitors, and contactor
  • Outdoor fan motor and indoor blower motor
  • Auxiliary heat strips and sequencers
  • Thermostat setup – heat-pump thermostats must be configured for a heat pump, and a wrong setting is a common cause of “emergency heat” complaints

Coastal Homes: Salt Air and Heat Pumps

Homes near the water in Ponte Vedra, the Jacksonville Beaches, and along the Intracoastal see faster corrosion on outdoor coils, fins, and electrical connections. If your heat pump is within a few miles of the coast, corrosion is one of the first things we look for, and regular rinsing and maintenance make a real difference.

Repair or Replace?

Repair is usually the right call on a newer system with a single failed part. Replacement is worth considering when:

  • The system is well into its second decade
  • It uses R-22 refrigerant, which has been out of production since 2020, so recharging it is expensive
  • Major components such as the compressor are failing on an older unit

We’ll lay out both options with written prices so you can decide. If replacement makes sense, see Heating Installation. Financing is available through GreenSky, subject to credit approval.

Heat Pump Emergencies

If your heat pump quits during a cold snap or a summer heat wave, our emergency dispatch is available 24/7. See Emergency AC Repair.

Keep It From Happening Again

Most of the repairs above start as small problems that routine maintenance catches early. See our Maintenance & Protection Plans.

Got Questions

Heat Pump Repair Questions

Answers to the questions we hear most often from homeowners whose heat pump isn’t working right.
Why is my heat pump blowing cold air?

During a defrost cycle it briefly blows cooler air for a few minutes, which is normal. If it lasts longer, the usual causes are a stuck reversing valve, low refrigerant, a failed outdoor fan, or a thermostat set up for the wrong system type.

Is it normal for my heat pump to ice up?

Light frost in cold, damp weather is normal, and the unit should clear it on its own every so often. Heavy ice, or ice that covers the whole unit and doesn’t melt, means the defrost system or airflow needs attention. Turn the system off and call us rather than chipping at the ice.

What does “emergency heat” mean on my thermostat?

Emergency heat turns off the heat pump and heats your home with electric resistance strips only. It’s meant for when the heat pump has failed. It works, but it costs much more to run. If your system is switching to it on its own, something needs repair.

Can a heat pump keep up with a Jacksonville winter?

Yes. Our winters are mild enough that a correctly sized heat pump handles them well, with the backup strips helping on the coldest mornings. If yours can’t keep up, that points to a problem worth diagnosing.

Do I get a price before you start?

Yes. You get a written price before any repair work begins.
