We service every part of the heat-pump lifecycle: repair on failing compressors, reversing valves, defrost boards, and metering devices; replacement when corrosion or repair history tips the math; and installation with the coastal considerations this market demands — coated coils, correct charge in both modes, and commissioning data that verifies heating and cooling performance separately.
Heat pump warning signs
- Cooling is fine but heat mode barely warms the house
- Outdoor unit ices up and stays iced
- Emergency heat runs constantly during cold snaps
- Short cycling — a few minutes running, then off
- Loud rattling or new humming from the outdoor unit
- Cooling capacity noticeably down from last summer
- Tripped breaker at startup
- Rising electric bills with no change in habits
What affects your price
These factors shape your final price. Published local benchmark ranges appear in the page copy where they're relevant — and you'll get every charge in writing before work begins.
- Compressor, reversing valve, or defrost-board failure scope
- Refrigerant type and whether a leak repair precedes recharge
- Coastal coil and cabinet upgrades near the water
- Strip-heat package sizing and control configuration
- Thermostat staging compatibility
- Duct condition and required airflow corrections

Repair: the parts that fail, in this climate
Heat pumps in salt air fail in recognizable patterns. Corroded outdoor coils lose capacity before they fail outright; defrost boards and sensors quit, letting ice smother the coil on humid cold mornings; reversing valves stick between modes; and run capacitors — worn by nine-month seasons — die at startup. None of these are exotic, but all of them are misdiagnosed without meters: charge readings in heat mode, defrost-cycle verification, and component amp draw.
Repair pricing follows the same logic as any AC repair — reported Stuart-area repairs commonly run $265–$383 with a broader range of $88–$754 — but heat-pump parts sit higher on the ladder than strip-heat parts. We quote line-item in writing, and when a reversing valve or compressor repair approaches the value of the system, we'll say so and show the replacement comparison beside it.
Replacement: right-sizing for humidity first
Heat-pump replacement here lives and dies on sizing. An oversized unit short-cycles, which hurts cooling dehumidification first — you feel it as a clammy house in July before you ever notice a winter problem. We size from a Manual J load calculation, match equipment with Manual S, and verify ducts can deliver the airflow the new system requires.
Near the water, coastal-rated equipment is the difference between a nine-year system and a fifteen-year system. Factory-coated coils, corrosion-resistant cabinets, and smart placement (out of surge reach, with rinse access) cost a little more on install day and repay it many times over. We also verify the strip-heat package and thermostat staging so auxiliary heat engages correctly — the difference between an efficient cold snap and a $400 January electric bill.
Maintenance: the year-round workload
Because a heat pump never gets a season off in Stuart, its maintenance calendar is fuller than a straight-AC home's. Filters check quarterly; coils rinse on a freshwater schedule for waterfront homes; drains treat before algae takes hold; and refrigerant charge gets verified in both modes — cooling in spring, heating in fall.
Our maintenance plan handles all of it on schedule, with corrosion inspection included as a standing item. Heat pumps that get this care routinely beat the coastal lifespan expectations; heat pumps that don't quietly lose capacity until the compressor dies years early. The service call is cheap; the equipment is not.
Our Heat Pump Services process
Test first, document everything, and get your sign-off before the work happens — no guesswork, no surprises.
- 1
Diagnose in both modes
We test cooling and heating performance separately — a heat pump can be fine in one mode and failing in the other.
- 2
Verify the defrost system
Timing, sensors, and termination temps are checked so winter icing is diagnosed, not guessed at.
- 3
Meter the electricals
Compressor, fan motor, and capacitor readings against nameplate catch failing parts before they strand you.
- 4
Quote line-item in writing
Repair cost, remaining-life context, and — when the numbers are close — a replacement scope beside it.
- 5
Fix, verify, and schedule care
Post-repair measurements confirm performance, and maintenance scheduling keeps the year-round workload covered.

Heat Pump Services FAQs
It's the best-fit system for most homes here. Stuart winters are mild enough that a heat pump covers nearly every cold snap efficiently, and the same equipment handles the long cooling season. The key is correct sizing for humidity and — near the water — coastal-rated coils, plus maintenance that respects the year-round workload.
