About Coastal Comfort San Diego
Family-owned HVAC contractor in Carlsbad, California — serving North County San Diego since 2024, with 30+ years of hands-on heating and air conditioning experience behind every job.
Our Story
Coastal Comfort San Diego was founded by Trever Blanc and is built on more than 30 years of hands-on residential HVAC experience. After three decades installing, repairing, and maintaining heating and cooling systems across San Diego County — first as a tradesman, then as a foreman, and finally as an owner — Trever started Coastal Comfort to give homeowners a different option from the corporate-owned franchises that have come to dominate the local market.
We are independently family-owned and operated. That matters more than it sounds. In the last decade, most of San Diego's well-known HVAC brands have been acquired by private-equity firms, where the business model centers on selling new equipment, charging premium pricing, and paying technicians on commission so they have an incentive to find more to sell on every visit. We work the opposite way: low overhead, no commissions, no sales quotas, and no pressure to upsell what is not actually needed.
When we show up to your home — whether it is a 1960s ranch in Vista with the original furnace, a coastal property in Encinitas where salt air is corroding the condenser, an estate in Rancho Santa Fe with multi-zone climate control, or a heat pump retrofit in Carlsbad to qualify for federal tax credits — we treat it like our own house. Straight answers. Fair pricing. Quality work that we stand behind.
