Two lifespans
Skip service and the condensate line clogs and overflows like any AC, while low refrigerant burns out the compressor, the most expensive part.
Overview
A heat pump does the job of a furnace and an air conditioner in one unit, which means it runs almost year round in Florida. That constant duty is why service twice a year, not once, is the difference between a decade and fifteen years.
The maintenance that buys you the years
- Have it servicedHigh impactTwice a year, spring and fall
Catches refrigerant, capacitor, and reversing valve issues before they kill the compressor.
- Change the filtersHigh impactMonthly to quarterly
Keeps airflow up and the blower easy.
- Keep the outdoor coil clearHigh impactOngoing
Leaves, grass clippings, and dryer lint blocking the coil overheats the unit.
- Keep at least two feet of clearance around the outdoor unitMedium impactOngoing
It needs airflow on all sides to work.
- Check the condensate drainMedium impactYearly
Prevents shutoffs and water damage.
Signs it is failing
- The unit runs in emergency or auxiliary heat all the time
- Ice building on the outdoor coil in cool weather
- Rising energy bills
- Short cycling on and off
Repair or replace
Under 10 years, most repairs are worth it. Past 12 to 15 with a compressor or reversing valve failure, replace.
The facts
Heat pumps are the most common central system in Florida because winters are mild. That also means they run more months than in colder states, so annual service is not enough. Twice a year is the standard.
