California is moving decisively toward heat pumps. Between updated Title 24 building energy standards and the ongoing transition away from older refrigerants under EPA rules, a heat pump isn’t just the energy-smart choice — it’s increasingly the future-proof one. For LADWP customers in Los Angeles, the timing has never been better to act.
Don’t miss out. Check Rebate Availability.
Multiple programs can be combined on a single installation where program rules allow, which means your total incentive can add up quickly on a 3- or 4-ton system.
A note on federal tax credits: The federal Energy Efficient Home Improvement Credit (Section 25C) applied to qualifying installations completed through December 31, 2025, and is not available for 2026 installations. If you installed a qualifying system in 2025, that credit may still be claimable on your 2025 return — consult a tax professional.
We identify every program you qualify for, prepare the rebate paperwork, and submit applications on your behalf wherever the program allows. Rebate funding is limited and approved on a first-come, first-served basis.

LADWP customers may be eligible, subject to program availability, for up to $2,500 per ton on qualifying heat pump HVAC systems purchased and installed on or after November 1, 2025, and $100 to $120 per ton on standard high-efficiency systems. Burbank Water and Power offers $1,000 per ton up to $2,500 for standard customers, and up to $5,000 for income-qualified residents and affordable housing providers. SCE offers a $75 smart thermostat enrollment bill credit, with up to $125 total available through ongoing participation.

Yes. Modern heat pumps operate efficiently at temperatures far below anything a Southern California winter produces. A properly sized heat pump provides both heating and cooling in a single system and, subject to program availability, may qualify for LADWP rebates of up to $2,500 per ton on qualifying installations.
Set your HVAC system to recirculation mode to limit outdoor air intake, upgrade to MERV 13 or higher filters if your system supports them, and schedule a professional duct cleaning if smoke has entered your home. Affordable Heating and Air also installs whole-home air purifiers, such as iWave and REME HALO, for continuous protection against wildfire smoke and other airborne pollutants.
As a general guide, if your system is under 10 years old and the repair costs less than $500, repair is usually the right choice. If the system is 15 or more years old and a repair would cost more than half the price of replacement, replacement typically makes better financial sense, especially with current LADWP heat pump rebates available to offset the cost. Our technicians provide an honest assessment based on your system’s actual condition.

Our Chatsworth office covers the San Fernando Valley and Greater Los Angeles, including Northridge, Granada Hills, Porter Ranch, Van Nuys, Glendale, and Santa Clarita.

I conducted a thorough pre-engineering evaluation for the replacement of the existing rooftop HVAC system. The evaluation included a detailed inspection of the current equipment, roof access points, ductwork integrity, thermostat wiring, and the sizing of return and supply grilles. The existing system, an older R-22 packaged unit, has reached the end of its service life. Based on the findings, the replacement process is expected to be straightforward, involving the installation of a new rooftop package unit. A crane will be necessary for the removal and installation of the equipment due to the building height and roof access. Additionally, the existing roof curb may require modifications or a new adapter to accommodate the dimensions of the new equipment. The current thermostat wiring, a basic four-conductor cable, should be replaced with new thermostat wire to ensure compatibility and future serviceability.
Upon arrival, I assessed the air quality system and identified that the filter required replacement. I carefully removed the old filter, ensuring no debris was left behind. I then installed a new, high-efficiency filter, making sure it was securely in place. I tested the system to confirm optimal performance and provided the customer with maintenance tips to prolong the filter's lifespan. The job was completed efficiently, ensuring the air quality system operates effectively.
I inspected a 1999 Rheem HVAC system, revealing neglected maintenance. The indoor blower wheel was clogged with dirt, and the motor showed rust. The evaporator coil was heavily soiled, reducing efficiency. The rooftop condenser had dirty coils, and the duct system had separated asbestos joints, causing air leaks. Due to asbestos, sealing the ducts was unsafe. I recommended replacing the entire system and ductwork to restore performance and indoor air quality.
Upon inspection, the system was found to be completely non-functional. The control system was missing, and there were multiple instances of crossed and exposed wiring, which posed significant safety hazards. The main breaker was severely damaged, rendering it inoperable. The installation of the equipment was notably substandard, with improper wiring and insecure connections throughout the system. I assessed the situation and determined that the system required a complete overhaul. I replaced the faulty main breaker and corrected all instances of crossed and exposed wiring. Additionally, I installed a new control system and ensured that all equipment was securely and properly connected. The system is now fully functional and safe for use.
We conducted a thorough diagnostic evaluation of the air conditioning system after the homeowner reported it was not cooling despite recent repairs. We verified the system was discharged of refrigerant, with resting pressures indicating minimal R-410A. A visual inspection of the indoor and outdoor equipment and piping was performed, but the leak source was not identified. We recommended a nitrogen pressure leak test to locate the leak accurately. We also discussed replacing the outdoor condenser, given the recent indoor coil replacement. No repairs were made during this visit.
Ziv was very informative and helpful and explained that my unit, which I know is older, is quite inefficient and he gave me a quote for a new system (plus any permit fees that may be needed) and I accepted the offer and gave him a down payment. The price Ziv quoted was something I could manage. A previous HVAC contractor had told me a couple of years ago that a new system would be more than twice what Ziv quoted and that scared me to death! I appreciate honesty and integrity in the people I work with. Thank you
Jan Michael was a really nice guy! He was kind and patient with my 80 year old mother too who wants to know every little detail about what he was doing. He was friendly and took the time to explain everything he was doing. He was also very clean, well put together and he smelled good too. Mom and I were very impressed with him and we also appreciated how quickly and efficiently he solved our problem. Mom doesn't always trust or like repair men, but she liked Jan. If we could give Jan more than 5 stars we would. Great guy
Totally perfect service. Same day and responsive! our AC running cool now
