A heat pump does two important jobs: it cools your home during Valley heat waves and keeps it warm on chilly January mornings.
Here, you’ll find details about our three main heat pump services: installation and replacement, repairs for broken systems, and routine maintenance to keep everything running smoothly.
We service ducted, ductless, and dual-fuel heat pump systems throughout Los Angeles County and Ventura County.
| Situation | What It Usually Means | Where to Go |
|---|---|---|
| System won't turn on, ice that won't clear, weak or no airflow | Repair | See below, or heat pump symptoms explained |
| Working fine, but it's been 6+ months since service | Maintenance | See below, or Care Club plans |
| No heat pump yet, or yours is old/undersized/failing repeatedly | Installation or replacement | See below, or repair vs. replace guidance |
Ducted air-source heat pumps connect to existing ductwork and are common in San Fernando Valley tract homes.
Ductless mini-split and multi-split systems need no ductwork, which fits older Craftsman-style and coastal homes that were never ducted.
Dual-fuel (hybrid) systems pair a heat pump with a gas furnace as a backup, useful when you want to keep gas heat available on the coldest nights.
Packaged units combine everything in a single outdoor cabinet and are sometimes used where indoor space is limited. We don’t currently offer geothermal as a standard service.
Modern systems are rated by SEER2 for cooling and HSPF2 for heating. Most equipment made for 2026 uses variable-speed compressors, which run at lower power for longer rather than turning on and off completely.
The latest systems commonly use R-454B (for ducted units) or R-32 (for many mini-splits) instead of R-410A. If you have an R-410A system, it can still be serviced and does not need to be replaced just because of the refrigerant. For a full comparison, see R-454B vs. R-410A.
We start by determining the right size for your home, rather than copying the old unit. We check your ductwork, electrical panel, and disconnect. We design the line-set and condensate system, handle permits and Title 24 paperwork, and do field verification (HERS testing) if needed.
Finally, we commission the system by checking airflow, refrigerant charge, defrost cycle, auxiliary heat lockout, and thermostat settings.
Diagnosis before parts are replaced. Typical problems include a reversing valve stuck in one position, defrost board or sensor faults, failed capacitors or contactors, blower problems, refrigerant leaks, and condensate drainage issues.
Charge verification procedures differ between R-410A and the newer A2L refrigerants, which is why technician training on both matters is necessary.
We clean the coils, check the refrigerant charge, test the reversing valve, verify the defrost cycle, inspect electrical connections, clear the condensate line, service the filter, and check the thermostat and time-of-use rates for SCE and LADWP customers.
In the fall, we also check the filter for any effects of wildfire smoke. Since heat pumps work year-round, we recommend servicing them twice a year. For general HVAC maintenance or Care Club enrollment, see our HVAC maintenance in Los Angeles.
If your system is less than 10 years old and hasn’t had repeated problems, a single repair is usually the right choice. If you have ongoing issues, a major compressor or coil failure, or a system that was never sized correctly for your home, replacement may make more sense. It’s not only about age—see our repair vs. replace decision support for more details.
San Fernando Valley systems work hard both in summer and winter. Long, hot August days stress outdoor units, while cold January mornings in the 40s require reliable defrost cycles. For dual-fuel systems, it’s critical to set the changeover point correctly.
In older Valley homes with original ductwork or attic heat loss, making sure the system is sized right and the ducts are in proper shape is just as critical as the equipment itself.
Our Simi Valley branch serves Ventura County. Inland cities like Simi Valley, Thousand Oaks, and Moorpark have hot summers and cold snaps, like the Valley, so dual-fuel systems are common there.
Coastal cities such as Oxnard, Ventura, Port Hueneme, and Camarillo face salt-air corrosion on outdoor coils and electrical parts, which isn’t an issue inland. For more details, see our pages on Thousand Oaks dual-fuel systems, Simi Valley heat pump installation, and the Ventura County service area.
Repairs and maintenance usually do not qualify for rebates; incentives are for upgraded equipment that meets certain requirements. In LADWP territory, current rates for equipment installed on or after November 1, 2025, are $1,000–$1,250 per ton for central ducted heat pumps. In addition, $1,500–$2,500 per ton for ductless systems that serve the whole home.
The highest $2,500 rebate requires 20.5 SEER2/9.1 HSPF2, which not all ductless systems meet. Funding, address, and AHRI-matched equipment all need approval. For the latest information, see California HVAC rebates.
Ventura County is in SCE territory, and 3C-REN may offer incentives there, depending on current funding, so check before making plans.
The federal 25C tax credit ended on December 31, 2025, so it does not apply to work done in 2026. HEEHRA single-family funding is also fully reserved right now, so check the current HEEHRA status before assuming funds are available.
Ducted systems usually cost between $8,500 and $15,000 to install. Ductless systems range from $3,000 for a single-zone setup to $15,000 for a multi-zone setup.
The final price depends on the system’s size, efficiency, ductwork, and electrical needs. We always provide a written estimate after assessing your home.
You should have your heat pump serviced twice a year. This is because it operates in both heating and cooling modes, unlike a furnace that runs only part of the year.
No, your existing R-410A system is still legal to use and service. The refrigerant change only affects upgraded equipment, not your current system.
Yes, we install heat pumps throughout Ventura County from our Simi Valley branch. We serve both inland communities and coastal areas, with specialized expertise in addressing the unique corrosion challenges found in coastal environments.
In LADWP territory, qualifying systems can get rebates of $1,000 to $2,500 per ton, depending on the type and efficiency. The federal 25C credit has expired and no longer applies to installations in 2026.
HEEHRA single-family funding is also fully reserved at this time. Be sure to check the latest program status before making your budget.
Yes. Modern heat pumps are designed to operate at temperatures much colder than Southern California. This includes the 40s common on Valley and inland Ventura mornings.
