About A SUBCOOL AIR CONDITIONING
A Subcool Air Conditioning operates from Lake Balboa, California, serving the San Fernando Valley with a perfect 5-star rating across 32 customer reviews. The company holds California contractor license number 568218 and provides air conditioning repair, heating system services, and complete HVAC installation throughout neighborhoods including Lake Balboa, Encino, Canoga Park, Granada Hills, Northridge, Reseda, and Sherman Oaks. Their service hours span seven days, with Monday through Saturday availability from 8 AM to 10 PM and Sunday hours until 5 PM, accommodating both routine maintenance appointments and urgent repair needs.
The contractor distinguishes itself through specialized water chiller service, a niche expertise that many general HVAC companies in the valley do not offer. Their business model emphasizes preventive maintenance to ensure long-term system reliability, and they back all parts and labor with a one-year warranty. The company provides complimentary estimates for new HVAC installations and maintains competitive service call pricing without hidden fees. This approach reflects their stated commitment to honest recommendations and transparent pricing, helping homeowners make informed decisions about repairs versus replacement.
Customer reviews highlight specific technicians who have handled challenging situations. Ara, described by multiple reviewers, diagnosed and repaired a furnace within two hours of a Saturday call, locating a difficult-to-find circuit board for an older unit. Another reviewer noted technician Mike arrived quickly during a heat wave with repair parts already on his truck, completing the fix without delay. A third customer mentioned Ara installed a Cooper and Hunter mini-split system, supplying the outdoor lineset cover and performing additional tasks beyond the original scope. These detailed accounts from verified customers demonstrate the hands-on approach that contributes to the company's perfect rating.
