Breathable

Since 2010, Breathable has served the Bay Area as a licensed mechanical contractor (CSLB #979977) with $2 million in insurance coverage. Based in Oakland, the team proudly installs heat pumps, cleans ductwork, and improves indoor air quality for homeowners across Berkeley, Alameda, and the surrounding East Bay communities. With nearly 227 Google reviews and a 4.9-star rating alongside 1,331 Yelp reviews, this locally owned operation has built a reputation for treating customers like neighbors rather than account numbers. The company operates seven days a week, with Saturday and Sunday availability from 10 AM to 5 PM.

What distinguishes Breathable is their commitment to whole-home comfort through a single experienced team. As a heat pump specialist, they install systems that move heat instead of burning fuel, making homes more energy-efficient while qualifying California homeowners for state rebates. Their air purification offerings work with existing HVAC equipment to filter allergens at the source, unlike room-by-room solutions. The company also handles full duct replacement and repair, catching issues like leaky duct returns that waste conditioned air and drive up energy bills. Every technician arrives in marked vehicles, tapes off work areas before starting, and thoroughly cleans up when finished.

Homeowners consistently praise owner Nir Biderman for his communication and follow-through. When Rebecca M in Oakland needed air conditioning during East Bay heat waves, Nir explained heat pump options, pricing, and a 2025 tax credit, then installed ductless mini-split units the next day. Her crew wore shoe covers indoors and explained how to operate the new system. Another reviewer, Lindsey, noted the team discovered and fixed an unknown duct return issue during cleaning. Juan leads another crew that masks entire houses during duct work, using a system where already-cleaned ducts stay sealed while the team finishes the job.
