Heat Pump Maintenance
Heat Pump Maintenance
A system that runs all year needs both modes checked — including the heating side nobody tests until it is cold.
A heat pump in Florida works harder than almost any other piece of domestic equipment. It runs nearly year-round on the cooling side, then switches direction for a handful of weeks and is expected to work first time. Maintenance that only ever looks at the cooling mode misses half the machine, which is why the first cold night of the year generates so many calls.
So a proper heat pump service tests both directions. Reversing valve operation, defrost cycle initiation and termination, auxiliary heat staging and lockout, and the outdoor sensor that decides when defrost is needed. Those are the components that sit unused for most of the year and are therefore the ones most likely to have quietly failed since you last needed them.
The rest is the same discipline we apply to any system, done with instruments rather than impressions: coil condition and cleaning, refrigerant charge verified, capacitor values measured against rating, contactor condition, blower and airflow, condensate drain and safety float. What you get back is a set of readings you can compare next year, which is the only way a maintenance visit tells you anything about the direction the equipment is heading.
What annual maintenance is protecting you from
- A reversing valve that has failed unnoticed since last winter
- Auxiliary heat quietly running whenever heating is called for
- A defrost fault that only shows up on a cold, damp morning
- Capacitors drifting below rating and failing on the hottest day of the year
- A coil losing heat rejection to salt and debris, raising running cost month by month
- A drain line blocking and shutting the system down at the worst moment
What a heat pump service includes
- Both modes tested — cooling and heating verified in operation
- Reversing valve, defrost board and defrost sensor checked
- Auxiliary heat strips, sequencers and lockout confirmed to stage correctly
- Coils cleaned; on coastal units, salt deposits rinsed off
- Capacitors measured against rated microfarads, contactor points inspected
- Refrigerant charge verified by superheat or subcooling
- Condensate drain cleared, pan cleaned, float switch tested
- Documented readings you can compare against next year's visit

Central Florida coverageHeat Pump Maintenance — common questions
How often should a Florida heat pump be serviced?
Twice a year is ideal for equipment that runs both modes — once before cooling season and once before the cold nights. Once a year is a reasonable minimum, and near the coast we would strongly favour twice because of salt.
Is this different from an AC tune-up?
Yes, and it is the reason this page exists. A cooling-only tune-up never tests the reversing valve, the defrost cycle or the auxiliary heat staging — the three things that decide whether your heating works and what it costs.
What do I actually get afterwards?
Readings. Temperature split, static pressure, capacitor values, charge verification and the condition of the components we inspected. That is what makes the next visit meaningful, because a number that is drifting tells you something a clean bill of health does not.

In Florida the heat pump is both the air conditioner and the heater. When it fails in reverse cycle, most of the system still looks fine.
