Categories: Uncategorized

Quick Answer: HVAC replacement in San Jose costs $8,000-$18,000 for a complete central air conditioning and gas furnace system (the most common HVAC type in Bay Area homes), including labor and all equipment. A mini-split system (for homes without ducts, or for additions and ADUs) costs $3,000-$7,000 per zone installed. A heat pump (replacing both cooling and heating in one system, which California’s 2023 building code favors for all-electric homes) costs $10,000-$22,000 for a central system. PG&E offers rebates of $400-$2,000 for qualifying heat pump installations under the Savings By Design program, and the federal Inflation Reduction Act provides a 30% tax credit (up to $2,000) for heat pump HVAC systems. San Jose building permit and mechanical permit are required for any new HVAC installation.

Ohad Maloul the owner was professional communicative and a pleasure to work with from start to finish. His team repaired and painted my backyard pergola and the quality of their work was truly excellent. They were always on time, friendly and responsive to any questions I had throughout the process. I appreciated the clear communication and attention to detail. I’m excited to work with Ohad and his team on future projects and highly recommend them to anyone looking for reliable, high-quality construction or remodeling services.

 Trustindex verifies that the original source of the review is Google. I had the chance to work with Ohad and his construction team on a recent home project, and I was really impressed. Ohad is professional, easy to communicate with, and genuinely cares about the quality of the work. The crew showed up on time, kept the work area clean, and finished the job on schedule. It’s hard to find contractors who are reliable and transparent these days, but Ohad delivered on everything he promised. Would definitely recommend if you’re looking for someone who takes pride in their work and keeps things straightforward.
