Got an estimate from this company to have an ac installed. All went well until the very end when the price suddenly went up to because they stated the labor charges were not included with the previous estimate after a long discussion. These things cast doubt with me. Maybe its still the best price but I will obtain other estimates to compare.Trustindex verifies that the original source of the review is Google.

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.

I returned to complete approved repairs on a 2021 Carrier 5-ton R-410A heat-pump system. Initially, the indoor blower operated, but the system failed to provide heating. Direct testing revealed that the outdoor unit operated, but the system remained in cooling mode, causing the indoor coil to freeze, indicating a failed/stuck reversing valve. I recovered the existing R-410A refrigerant, removed and replaced the faulty reversing valve, and flowed nitrogen during brazing to minimize internal oxidation. The system was evacuated twice, achieving 495 microns on the first evacuation and below 550 microns on the final evacuation. I recharged the system by weight to approximately 11 lb 13 oz, tested operation in both heating and cooling modes, and confirmed the new reversing valve shifted properly. Final readings showed 99.5 psig suction, 264.5 psig liquid, 15.1°F superheat, and 9.4°F subcooling. The cooling temperature split was 17.7°F, with 65.0°F return and 47.3°F supply.

I meticulously gathered all necessary pictures and measurements to facilitate pre-job engineering. This involved a thorough inspection of the area to ensure accuracy. I used high-resolution cameras to capture detailed images of the space, focusing on key structural elements and any potential challenges. Additionally, I took precise measurements of dimensions, distances, and angles, ensuring that every aspect was documented. This comprehensive data collection was crucial for creating an accurate engineering plan, which will guide the subsequent phases of the project. My attention to detail ensured that all critical information was captured, setting a solid foundation for the project's success.


On the installation date, I successfully completed the setup of an AC Pro J-Series 12K BTU up to 21.2 SEER2 single zone 115V mini split condenser and wall-mounted air handler, both utilizing R454B refrigerant. The installation included mounting the condenser and air handler, installing a new disconnect box, power whip, condenser rack, condensation line, mini split line set, electrical lines, and a new breaker. Additionally, I installed a condensation pump and mini-split wall bracket. Both supply ducts on the ceiling were capped to prevent airflow interference. The permit and HERS test costs were included in the price. The system is now ready for the landlord to handle patching and painting. The AC Pro warranties cover 1 year of labor, 10 years on factory parts and compressor, and 20 years on the heat exchanger, contingent on regular maintenance records.


Upon inspection, the indoor unit’s drain pan was found to have a significant accumulation of lint and grime, which was impeding proper drainage. I meticulously vacuumed out the accessible debris to enhance the unit’s drainage efficiency. Additionally, the blower wheel was heavily coated with dust and debris, indicating a need for a thorough deep cleaning. Although I addressed the immediate issue, the leak may persist until a comprehensive deep cleaning is performed, as some buildup remains in areas that were not accessible during this visit. A full cleaning will ensure optimal performance and prevent future leaks.
He was highly courteous and patient. Was able to give the information I needed & completed cleaning my furnace very well. No pressure on the quote he gave me.
