Heat pumps are one of the most common systems in South Florida homes, and for good reason. They cool just like a standard air conditioner, then reverse the process to provide efficient heat on the cool mornings that show up between December and February. One system covers both jobs without a separate furnace.
Sunshine State HVAC repairs, maintains and installs heat pumps for homes and light commercial spaces across Broward, Palm Beach and Miami Dade counties. Our licensed HVAC technicians understand the parts that make heat pumps different, from the reversing valve to the defrost controls and backup heat strips.
We service all major brands and give you a clear quote before any work begins. Call (954) 800-2561 or use the Book an Appointment form for same day service when it is available.
How a heat pump works in South Florida
A heat pump moves heat instead of creating it. In cooling mode, it pulls heat out of your home and releases it outdoors, exactly like a central air conditioner. In heating mode, a reversing valve flips the flow of refrigerant so the system pulls heat from the outdoor air and brings it inside.
Because our winters are mild, a heat pump can provide heat very efficiently for most of the year when heating is needed at all. Many systems also include electric heat strips in the air handler as backup for the coldest mornings or when the system is defrosting.
In practice, your heat pump spends the vast majority of its life in cooling mode. That means it faces all the same wear as an air conditioner, plus a few heat pump specific components that need attention.
That is also why a heat pump that has sat in cooling mode all year deserves a quick check before winter. Valves and heat strips that have not been used in months are exactly the parts most likely to surprise you when the first cold front rolls through.
Signs your heat pump needs service
If the system blows warm air in cooling mode or cool air in heating mode, the reversing valve or its solenoid may be sticking. That is one of the most common heat pump specific failures and something a standard AC never deals with.
A burning smell the first time you turn on the heat each winter is often dust burning off the heat strips and usually fades quickly. If the smell persists, or if a breaker trips when the heat comes on, have the strips and wiring inspected.
Other signs include the outdoor unit icing over and not clearing, loud whooshing or banging during defrost, short cycling, higher than normal FPL bills, and the thermostat showing "aux" or "emergency heat" far more often than it should.
Heat pump repairs we handle
Our technicians diagnose and repair the full range of heat pump issues. On the electrical side, that includes capacitors, contactors, fan motors, control boards and the wiring that runs to the heat strips.
On the refrigerant side, we troubleshoot reversing valves, check valves, expansion devices and refrigerant leaks in the indoor and outdoor coils. Salt air corrosion is a frequent cause of coil leaks in coastal homes, and we will tell you honestly whether a coil is worth repairing.
We also repair defrost controls and sensors, condensate drain and float switch problems on the indoor air handler, and thermostat issues where the system is not switching modes correctly. After every repair, we test the system in both cooling and heating to confirm it works both ways.
Why thermostat setup matters with a heat pump
Heat pumps need a thermostat that is set up correctly for heat pump operation. A thermostat configured for a conventional system can energize the reversing valve at the wrong time or bring on the expensive backup heat strips more than necessary.
The "emergency heat" setting deserves a mention. It turns off the heat pump and runs only the heat strips, which is useful if the outdoor unit fails but costly to leave on. If your system seems to be running on emergency heat, it is worth a call.
Upgrading to a smart or programmable thermostat can help a heat pump run more efficiently, as long as it is wired and configured correctly. Our thermostat installation and repair service covers heat pump setups.
Heat pump maintenance
Heat pump maintenance covers everything a standard AC tune up does, including cleaning the coils, flushing the condensate drain, testing capacitors and checking refrigerant levels. Because the system runs nearly year round, that baseline care is essential.
On top of that, the technician tests the reversing valve by switching the system between modes, checks the defrost control, and inspects the heat strips and their safety limits. Doing that check before winter means you will not discover a problem on the first cold night.
For many South Florida homes, a maintenance visit once or twice a year keeps a heat pump running efficiently. Learn more about what a visit covers on our AC maintenance and tune ups page.
Repair or replace your heat pump
The repair or replace question for a heat pump comes down to the same basics as any AC system: the age of the equipment, the cost and type of the failed part, and how reliable the rest of the system has been.
Replacement deserves a closer look when an older heat pump needs a compressor, a reversing valve plus a refrigerant recharge, or a new coil, especially on an R22 system. Major refrigerant side repairs on older equipment are often hard to justify.
A modern heat pump on a current refrigerant such as R454B, at a higher SEER2 rating, can noticeably lower operating costs. We will give you a clear quote for both the repair and a replacement so you can compare them directly.
Installing a new heat pump
If you are replacing an older AC or heat pump, a new heat pump is a practical choice for South Florida homes. You get efficient cooling plus heat for winter in one system, without gas lines or a separate furnace.
Like any AC replacement, a heat pump needs to be properly sized for your home's cooling load, paired with ductwork that can handle the airflow, and installed under a mechanical permit from your city or county building department. We handle the permit and inspection.
Condo and HOA approval rules apply to heat pump installations the same way they apply to standard AC systems. For the details on sizing, efficiency and permitting, see our AC installation and replacement page.
What drives the cost of heat pump work
For repairs, cost depends on the failed part and how hard it is to reach. Electrical parts like capacitors and contactors are usually simpler jobs, while reversing valve replacement involves recovering refrigerant, brazing and recharging the system, which takes more time.
For replacements, system size, SEER2 efficiency level, variable speed versus single stage operation, and installation conditions all affect the price. Attic air handlers, rooftop condensers and duct or electrical changes add complexity.
Whatever the job, we explain what is driving the number and provide a clear quote before work begins. You decide how to proceed once you have the full picture.
Keep running costs in mind as well. A heat pump that leans on its backup heat strips too often, or one with a slow refrigerant leak, can cost more each month than the repair itself. Fixing the underlying issue usually pays off in lower bills.
Heat pump FAQs
Is a heat pump different from a regular AC? In cooling mode it works the same way. The difference is the reversing valve and related controls that let it run in reverse to provide heat.
Why does my outdoor unit steam in winter? That is usually the defrost cycle melting frost off the coil, which is normal on cool, damp mornings. If ice builds up and does not clear, have it checked.
Can you service my brand? Yes. Our licensed technicians work on all major heat pump brands. To schedule service, book an appointment online.
Tell us which mode is acting up
When you call, let us know whether the problem shows up in cooling, heating or both, and whether the thermostat is showing aux or emergency heat. Those few details help the technician come prepared with the right parts and testing plan for your specific heat pump.
Tested in both directions
A heat pump that cools fine can still have a heating problem waiting for the first cold front. Our technicians check operation in both modes on every visit, so you know the whole system is ready instead of finding out on a chilly January morning.
Clear quotes on repair or replacement
If your heat pump has a major failure, we price the repair and a replacement option side by side. You see the full cost of each before anything moves forward, which makes it much easier to decide what makes sense for your home and budget.
