Tetra Heating & Air Conditioning

Tetra Heating & Air Conditioning operates as a residential HVAC contractor in Simi Valley, California, earning a 4.4-star average across seven customer reviews. The company maintains around-the-clock availability, serving Simi Valley and neighboring communities including Thousand Oaks and Moorpark. Their team handles new installations, replacements, and system repairs for both heating and cooling equipment.

What distinguishes Tetra is specialized expertise with challenging home configurations. Their team, including lead technician Mike, has installed Daikin mini-split systems in multi-story hillside properties with vaulted ceilings, a scenario many contractors avoid. They also provide whole-house fan installation for enhanced air circulation and specialize in zoned cooling solutions that address uneven temperature distribution common in two-story homes. This focus on problem-solving rather than cookie-cutter installations sets them apart in the region.

One homeowner described a complex situation: a two-story house built into a hill where upstairs temperatures soared while downstairs remained cold. Mike's crew resolved this by installing a five-head Daikin system paired with a whole-house fan, enabling individual room control. However, a separate review detailed a negative experience with incomplete work and communication issues, showing service quality can vary between jobs.
