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.

They live up to their name in that they’re an inexpensive option. Unfortunately that comes at a cost. The business office and the business practices leaves a bit to be desired. I received an email essentially begging me for my business. When I tried to reach Gene, they were nowhere to be found. The person that I did get on the phone (Lorraine) with was ill informed and I caught her in a few lies that were easily verifiable. The “tech”that came out initially to fix my AC (Benji) was a salesperson with the pretense to sell me a new unit rather than repair it. He had a gruff personality and when I questioned why something was on my proposal, rather than validating his recommendation (even if I truly needed it) he chose to remove the item from the proposal altogether. I had to call a friend in the industry to get an answer to a question that Benji could not answer. The tech that installed my HVAC showed up late and only did a detailed job because I was looking over his shoulder the whole time. He wanted to cut corners a few times but I did not allow this. There was however something that I needed that would’ve taken him an hour or so of additional work that he refused to do. He lied to me and his boss and said it couldn’t be done. (2 other installers told me it could and should be done). When I called the office to let them know what was going on here I spoke to Leon who was very curt and rude and of zero help. All throughout the day I heard the tech and Leon yelling and cursing at each other.Everyone in that office talks crsp about eachother.If you can handle the drama they actually did a DECENT job and had the best price.
Came out to do preventative maintenance on AC unit. Upon checking the temperature split of the system, found that there was only 11° temperature split. Upon checking the outdoor unit found that refrigerant was low and unit is leaking, and also coil was freezing. Recommended doing a pressurized leak check to find out where the leak is and repair it.

Returned today to inspect the attic duct system before installation of the new HVAC equipment. A total of eight existing supply duct runs were evaluated. Multiple ducts were found compressed, sharply bent, poorly supported and restrictive, which can reduce airflow, create uneven temperatures, increase system static pressure and negatively affect the performance of the new equipment.Due to the age and condition of the existing duct system, replacement is strongly recommended as part of the new system installation. Recommended improvements include:* Install a new properly sized and sealed supply plenum. * Replace all eight supply runs with six 8-inch and two 6-inch R-8 insulated flexible ducts. * Properly stretch, route and support the new ducts to minimize compression and airflow restriction. * Install balancing dampers and reconnect the ducts to the existing supply registers. * Seal all duct and plenum connections. * Increase the existing return-air opening to approximately 20 × 30

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.
The serviceman was knowledgeable, and very through.
