What Our Heat Pump & Mini Split Service Includes
Heat Pump Repair
A heat pump moves heat instead of generating it, which makes it efficient, but also means more moving parts that can fail. You’ll know you need heat pump repair when the unit blows cold air in heat mode, ices over repeatedly, or runs constantly without reaching temperature. Our technicians diagnose refrigerant levels, reversing valve operation, and defrost controls on-site, and we stock common OEM parts for Rheem, York, and other major brands so we’re not ordering parts and making you wait.
Heat Pump Installation
Heat pump installation makes sense when your current unit is 12+ years old, needs R-22 refrigerant that’s no longer produced, or your energy bills have climbed despite normal use. We size every system using Manual J load calculations, not rules of thumb, because an oversized heat pump short-cycles and wastes energy while an undersized one runs itself to death. Jason Trent personally reviews each installation plan before our crew arrives, and we handle permit coordination with local California building departments.
Mini Split Install
Mini splits are ductless systems with an outdoor compressor and one or more indoor wall or ceiling units, ideal for California homes without ductwork, room additions, or converted garages. Installation requires precise refrigerant line routing, electrical work, and mounting that won’t compromise your wall structure. We’ve installed Daikin and Bryant mini splits in bungalows across San Leandro, historic homes in Sacramento, and modern ADUs in Vista, so we know how to run lines cleanly through attics, crawlspaces, or exterior conduit.
Mini Split Repair
Mini split problems often show up as error codes on the indoor unit, water leaking from the wall mount, or weak airflow from a single head while others work fine. These systems use inverter-driven compressors and electronic expansion valves that require specific diagnostic tools, not guesswork. Our technicians carry digital manifold gauges and manufacturer software to read fault codes directly, which saves time and prevents misdiagnosis that leads to repeat visits.
Ductless System
Ductless systems cover both single-zone mini splits and multi-head configurations that heat and cool without any ductwork at all. They’re increasingly popular in California for their zoning flexibility and because they avoid the energy losses of leaky ducts in unconditioned attics. We service and install ductless systems from all nine brands we cover, and we’ll tell you honestly when ductless is the right call versus adding ductwork to an existing forced-air system.
Multi-Zone System
Multi-zone systems connect multiple indoor units to a single outdoor compressor, letting you set different temperatures in different rooms. Installation complexity scales with the number of zones, refrigerant line lengths, and whether you need ceiling cassettes, wall mounts, or floor consoles. We’ve designed multi-zone layouts for multi-generational homes in Baldwin Park and small office suites in West Sacramento, always balancing capacity against the outdoor unit’s maximum connectable load.

Brands We Service for Heat Pump & Mini Split
We’ve worked on hundreds of Rheem heat pumps across California, from the entry-level Classic series to the Prestige variable-speed models, and we keep common Rheem defrost boards and pressure switches in our vans. York systems show up frequently in Northern California subdivisions built in the 2000s, we’ve replaced dozens of their failed scroll compressors and know the quirks of their earlier control boards. Daikin is a leader in mini split technology, their VRV and Aurora lines are popular in Vista and coastal areas where corrosion resistance matters, and our technicians are trained on their proprietary inverter diagnostics. Bryant heat pumps share DNA with Carrier equipment, we’ve serviced their Evolution and Preferred series throughout the Central Valley, and we understand how their communicating thermostats interact with outdoor units.
We also work on Trane, Lennox, Goodman, and American Standard heat pumps and mini splits. Whether you have a 15-year-old Goodman in Valinda or a new American Standard AccuComfort system in Covina, we can source parts, read the diagnostics, and fix it without the “we don’t service that brand” runaround. Nine brands, one team, no dead ends.
Signs You Need Heat Pump & Mini Split Right Now
- Blowing cold air in heating mode. This usually means a stuck reversing valve or low refrigerant charge, both of which need professional repair. Running the system in this condition strains the compressor and can turn a $200 fix into a $3,500 replacement.
- Ice buildup on the outdoor coil that doesn’t melt during defrost. Some frost is normal in cold weather, but thick ice that persists indicates a defrost sensor failure, bad reversing valve, or airflow blockage. Left alone, it can damage the coil and flood the unit when it finally thaws.
- Water dripping from the indoor mini split head. A clogged condensate drain or cracked drain pan will eventually damage your wall, flooring, or ceiling. In humid California winters, this can escalate from nuisance to mold risk within days.
- Loud grinding, clicking, or buzzing from either unit. Heat pumps and mini splits should run quietly, unusual noises point to failing bearings, loose refrigerant lines, or electrical arcing. Shut the system down and call before the damage spreads to connected components.
- Energy bills jumping 30% or more with no rate change. When heat pumps lose efficiency, they run longer to deliver the same heating or cooling. This often precedes total failure by weeks, so early diagnosis saves both money and a mid-winter emergency call.
Our Heat Pump & Mini Split Process — Step by Step
- 1
Call and schedule. When you call (855) 467-1888, we ask about your system model if you know it, the symptoms you’re seeing, and when the problem started. This lets us dispatch the right technician with the right parts, not a generic troubleshooting visit.
- 2
On-site diagnosis. Our technician arrives with digital gauges, amp probes, and manufacturer-specific diagnostic tools. We test refrigerant pressures, electrical draws, airflow rates, and control signals to pinpoint the failure, not just the symptom.
- 3
Upfront estimate. Before any work begins, you get a written estimate with parts, labor, and timeline. Jason Trent reviews complex or unusual jobs personally, and we explain your options, repair versus replace, with real numbers.
- 4
Repair or installation. We complete the work using OEM or equivalent parts, pressure-test refrigerant lines, verify electrical connections, and run the system through full heating and cooling cycles to confirm operation.
- 5
Documentation and follow-up. You receive invoice details, warranty information, and maintenance recommendations. For installations, we file permit paperwork and schedule inspections. We follow up within 48 hours to confirm everything is performing as expected.
How Much Does Heat Pump & Mini Split Cost in California?
A typical heat pump repair in California runs $150–$650 depending on what’s failed. Refrigerant leaks, capacitor replacements, and sensor swaps sit at the lower end. Compressor replacements, reversing valve jobs, or major electrical repairs push toward the upper range. Mini split repairs follow similar pricing, though some inverter board replacements can run higher due to part costs.
Heat pump installation typically falls in the $3,500–$7,500 range for residential equipment, with final cost driven by system size, efficiency rating (14 SEER minimum in California, though many homeowners choose 16–18 SEER for rebate eligibility), and whether your electrical panel needs upgrading. Mini split installation varies more widely, a single-zone system might start around $3,500 while a four-zone multi-split with ceiling cassettes can exceed $7,500.
Several factors push price up or down. Existing ductwork in good condition saves money on heat pump replacement. Long refrigerant line runs, difficult access for outdoor units, or needed electrical upgrades add cost. We include full system testing, thermostat programming, and basic homeowner orientation in every installation estimate. Our estimates are free, detailed, and valid for 30 days, no pressure to decide on the spot.
To avoid overpaying, get at least one other estimate that includes equipment model numbers, not just brand names. Some contractors quote generic “3-ton heat pump” pricing then install lower-tier equipment. We specify the exact model, efficiency rating, and warranty terms in writing. Call (855) 467-1888 for your free estimate.
