L & O Heating & Air Conditioning Services

L & O Heating & Air Conditioning Services has been serving Simi Valley residents for over two decades, delivering residential and light commercial heating and cooling solutions across Ventura County. Backed by California state licensing and a solid 4.4-star average across seven verified customer reviews, the company has built a reputation rooted in transparent pricing and reliable workmanship. The team operates Monday through Friday from 7 AM to 4:30 PM, providing emergency response capabilities when temperature extremes strike the San Fernando Valley region.

What distinguishes L & O from regional competitors is their commitment to straightforward communication and efficient service delivery. Unlike contractors who burden homeowners with technical jargon, the team takes time to walk clients through their HVAC systems in accessible language. Multiple reviewers specifically praise the technicians for arriving on schedule, working efficiently, and delivering fair pricing without the runaround typical of larger chains. The company handles both routine maintenance tune-ups and complete system replacements, with particular strength in diagnostic assessment and equipment recommendations tailored to Southern California climate demands.

Customer narratives reveal the human side of this operation. During a brutal late-June heat wave, Scott responded rapidly to replace a thirty-year-old AC unit that had failed completely, installing quality equipment within the promised timeframe despite peak-demand pricing pressures. Long-term clients like Pam Abernathy maintain an ongoing relationship with specialist Jovany for annual maintenance, while Bryant Juarez credits Andy and his team for transforming a confusing system into one he actually understands. Even negative feedback from Riley Steagall regarding a rat-in-the-unit emergency after-hours situation demonstrates this contractor handles unconventional service calls that many companies would decline.
