Florida Heat Pump (FHP) Service in Phoenix, AZ
The nameplate on the unit in the ceiling says FHP. The company is Bosch. The building is thirty years old. Here is what that means.
Florida Heat Pump built water-source heat pumps in Fort Lauderdale for decades before Bosch acquired the company in 2007, and the FHP nameplate is on thousands of units in the ceilings and closets of Phoenix office buildings, hotels and apartment communities built from the 1980s through the 2000s. Owners of those buildings search for the name on the plate, and the answer is that the equipment is supported through Bosch and the general parts market, and that Bleuwave services it as an independent contractor.
An FHP-badged unit is, by definition, at least fifteen years old, and many are twice that. The units were built well and the water-source design is forgiving, but age and Phoenix water have taken their toll. Most FHP fleets are at the point where the right conversation is about a phased replacement schedule, not about the next repair.

FHP Equipment in Service
Horizontal, vertical and console water-source heat pumps in the LM, LV, EC and MC lines and their predecessors, on R-22 for the most part, with simple electromechanical or early electronic controls. Parts support continues through Bosch for most mechanical components; some controls and specialized components have become scarce.
Repair and the Phased Replacement Conversation
FHP units at this age show scaled coaxial heat exchangers, worn compressors, stuck reversing valves, failed water valves, corroded cabinets and drain pans, and R-22 charges that make major refrigerant-circuit repairs uneconomic. Minor repairs — a contactor, a blower motor, a water valve — remain sensible on units that are otherwise sound. A compressor or heat-exchanger failure on an R-22 FHP unit is a replacement, and a new unit drops into the existing loop connections with better efficiency and quieter operation.
Because water-source units are replaced individually, an FHP fleet is replaced on a schedule — oldest and least reliable first, by floor or as tenant spaces turn over — and the loop equipment is assessed alongside it. We build that schedule from maintenance data so it fits the capital plan.
Straight Answers
Questions About Florida Heat Pump Equipment
Can FHP units still be repaired?
For most mechanical components, yes, through Bosch and the general parts market. Whether a major repair is worth making on an R-22 unit this old is the real question, and we answer it with numbers.
Who makes FHP now?
Bosch Thermotechnology, which acquired Florida Heat Pump in 2007 and continues the product lines under the Bosch name.
How do we replace an FHP fleet without shutting down the building?
One unit at a time. Water-source systems are designed for it. We schedule replacements by age and reliability, floor by floor, so no tenant loses cooling.
