About Keith Heating and Air Conditioning
Keith Heating and Air Conditioning has been serving Simi Valley homeowners since 2008, building a reputation through 53 verified customer reviews that consistently award the company 4.8 stars. The business operates under state contractor license and maintains a team of technicians who handle residential heating, cooling, and ventilation systems throughout the Simi Valley area, including neighboring communities in Ventura County.
What distinguishes this contractor from competitors is their commitment to rapid response during climate emergencies. Reviewers consistently mention same-day service arrival, including instances where technicians reached homes after 8 PM on the hottest days of the year. The company offers straightforward pricing without upselling, with multiple reviewers noting they received the most competitive quotes in Simi Valley after comparing estimates from other local HVAC companies. This combination of availability and fair pricing addresses the two most common frustrations homeowners face with HVAC contractors.
Sherry Isom's review illustrates the company's approach: when her AC unit failed, Keith Heating installed a replacement system the following morning, then returned the next day when the thermostat also failed during a heat wave. Farshad java specifically praised technician Jared for honest guidance on a 40-year-old system replacement, noting the team honored their quoted price despite receiving lower bids from competitors. Shyam Parekh appreciated that owner Keith arrived on a Friday afternoon with no advance notice and completed the repair at the lowest cost among four quotes he collected. These named technicians demonstrate the company's capacity for flexible scheduling and transparent communication under pressure.
