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.

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 $1,000 to $1,250 per ton on qualifying central ducted systems, or $1,500 to $2,500 per ton on qualifying ductless mini-split systems (20.5+ SEER2 / 9.1+ HSPF2).

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.
We serve Los Angeles County and Ventura County. 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 recently completed a service for a customer involving the installation and setup of a new HVAC system. After ensuring the system was functioning correctly, I provided a thorough walkthrough of the unit's features and maintenance requirements. I also took the time to explain the warranty coverage in detail, highlighting the duration and what it includes. I made sure the customer understood how to access support and what steps to take in case of any issues. Additionally, I scheduled a follow-up visit to check on the system's performance and address any questions or concerns the customer might have. This comprehensive approach ensures the customer is fully informed and confident in their new system.
I conducted a thorough assessment of the existing window unit to determine its efficiency and functionality. I measured the dimensions of the window space to ensure a proper fit for a new unit. I evaluated the electrical requirements and assessed the need for any additional components. I provided a detailed estimate that included the cost of the new window unit, installation labor, and any necessary accessories. I explained the benefits of the recommended unit, including energy efficiency and noise reduction. I ensured the client understood the timeline for installation and any potential disruptions. The estimate was presented in a clear and concise manner, allowing the client to make an informed decision.
Juan was our technician he was prompt. He called if he was going to be late he was able to tell us exactly what was wrong with the system and what we needed to do to fix it. He couldn’t do it that day, but he was able to come back the next day and completely fixed the system I would recommend him to all.
Upon inspection, it was confirmed that the system lacked refrigerant. The system, purchased from Home Depot and installed by an external party, required thorough vacuuming and recharging. Our team meticulously evacuated the system to remove any contaminants, followed by a precise recharge with the appropriate refrigerant. We ensured the system was functioning optimally, adhering to safety and efficiency standards. Payment is structured as a 50% deposit upfront and a 50% balance upon completion.
I inspected the customer's 35,000 BTU natural gas wall furnace, which was experiencing issues with the pilot light not staying lit. The unit, showing significant age and corrosion, is an older model. After thorough examination, I determined that repair is not advisable due to its condition. Potential repairs would require replacing the gas valve, thermocouple assembly, and heat-only thermostat. Given the unit's age, successful repair and continued reliable operation cannot be guaranteed. I recommended considering a replacement instead.
The serviceman was knowledgeable, and very through.
Karma was knowledgeable about the maintenance needed and explained how important it was to consistently change the filter in order to prevent more expensive maintenance down the road which I appreciated.
