Javier was awesome I’m still waiting on pricing but he was very efficient in trying to diagnose the issue .Trustindex verifies that the original source of the review is Google.
The maintenance guy, Karma, was on time, helpful, gave me good advice, and cleaned both my splits. I just have to mention again that your company's pricing is so reasonable compared to my previous HVAC company, formerly a small family company that was bought out by a larger business that hopes to soak its clients with outrageous charges. From no on I am sticking with Affordable.Trustindex verifies that the original source of the review is Google.

No one ever wants their AC to go out, let alone during the hottest week, but Affordable came through like champs and sent one heck of an amazing technician, Jeremy. I was able to get him to my place the same day and got the issue diagnosed, ordered the part, and had it installed as soon as they received it. He was super friendly and courteous, and for sure 10/10 recommend and will continue to use him and Affordable from this point forward.

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.
These increased rates apply to qualifying equipment purchased and installed on or after November 1, 2025. The amount depends on the AHRI-matched system’s SEER2 and HSPF2 ratings.
Standard high-efficiency air conditioners may qualify for $100 to $120 per ton.

Yes. Affordable Heating and Air provides true 24/7 emergency HVAC repair by phone dispatch across Los Angeles and Ventura County. Our emergency line is answered 24 hours a day, 7 days a week.
Our physical offices in Chatsworth and Simi Valley are staffed during regular business hours, but emergency repairs are dispatched any time, day or night. Call (818) 722-1332 for Los Angeles County or (805) 755-4074 for Ventura County.
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 that serve the entire home.
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.

Upon arrival, I inspected the thermostat, which was unresponsive. I examined both high and low voltage, finding the low voltage at 10v instead of the required 24v. I traced the issue to damaged wires, which I carefully cut and rewired. After re-establishing the connections, I measured 27v, ensuring proper functionality. The thermostat was reinstalled, and the system successfully turned on, restoring cooling.
Javier is incredible. Very through and helpful. Took the time to explain everything and make it clear. Could not be happier with the experience.


I recently completed a thorough cleaning of two mini split systems for a customer. This involved inspecting and cleaning both the indoor and outdoor units. I carefully removed and cleaned the air filters, ensuring they were free from dust and debris. Next, I cleaned the evaporator and condenser coils using specialized tools and cleaning solutions to enhance efficiency and performance. Additionally, I checked and cleaned the drain lines and pan to prevent any potential clogs or leaks. Finally, I tested both units to ensure they were operating correctly and provided the customer with maintenance tips to prolong the system's lifespan.
Upon arrival, we assessed a vacant unit with an air conditioning system that was not functioning properly. The unit was not cooling as expected. To address the issue, we accessed the roof through the balcony of unit 202, which was unoccupied at the time. However, due to the absence of the resident in unit 202, we were unable to complete the necessary work. Consequently, we have rescheduled the service to a later date.


Upon returning, I discovered the thermostat was again displaying a no-power error due to the SS2 safety switch being tripped from water accumulation in the auxiliary drain pan. I removed the water, reset the SS2, and restored power to the thermostat. Additionally, I extended the primary drain breather above the evaporator coil drain outlet and replaced and secured the PVC connection at the secondary drain opening to enhance the seal. The system is now operational. I advised the homeowner to monitor the system closely. If issues persist, further repairs will involve rebuilding the primary P-trap, clearing the condensate drain line with nitrogen, and installing an additional SS2 safety switch at the secondary drain opening.
Excellent service
Arrived promptly. Explained clearly recommended work and clearly showed completion. A very pleasant person to deal with.
