AC Installation & Replacement in the East Bay
A new air conditioning system is one of the biggest comfort investments you'll make in your home — and the quality of the installation matters as much as the equipment itself. An incorrectly sized or poorly installed system costs more to run, cools unevenly, and fails years early.

Why Oren's HVAC Services for AC installation
Oren's HVAC Services installs and replaces AC systems across the East Bay — including the many older Oakland, Berkeley, and Alameda homes that were never built with cooling in mind. We size every system to your home with a proper load calculation and install it to manufacturer specification, so it performs the way it should from day one.
Right-sized, not oversold
We calculate what your home actually needs based on square footage, insulation, sun exposure, and ductwork — and recommend the system that fits, not the most expensive one on the truck.
Adding AC to homes that never had it
Victorians, Craftsman bungalows, and mid-century homes across the East Bay were built for the coast's mild summers. Retrofitting cooling into them takes real planning — ductless mini-splits, careful duct design, and equipment matched to the house.
Licensed HVAC installation
Installation by a licensed HVAC contractor, with permits and code compliance handled properly for your Alameda or Contra Costa County jurisdiction.
Efficiency that pays you back
With PG&E energy costs where they are, a modern high-SEER2 system can meaningfully cut what you spend cooling your home through an inland East Bay summer versus a 10–15 year old unit.

Popular service areas
AC Installation — common questions
How do I know what size AC my home needs?
We perform a load calculation that accounts for your home's square footage, layout, insulation, windows, and sun exposure. Oversized systems short-cycle and undersized systems never catch up — correct sizing is the foundation of a good installation, especially in older East Bay homes.
Can you add AC to an older Oakland or Berkeley home with no ductwork?
Yes — this is one of the most common projects we do. Ductless mini-splits are an excellent fit for Victorians, Craftsman bungalows, and additions where running new ducts is impractical. We design the system around how your home is actually built.
Do you handle permits for AC installation?
Yes. As a licensed HVAC contractor we handle the permit and code-compliance side of the installation properly, across Alameda County and Contra Costa County jurisdictions.
Do you install ductless mini-split systems?
Yes. We install central systems, heat pumps, and ductless mini-splits — a great option for older homes without ductwork, additions, ADUs, and garages.
Will a new system really lower my bills with PG&E rates this high?
A modern high-efficiency system uses substantially less energy than an aging one, which matters a lot at current PG&E rates. We'll also point out any current manufacturer or utility rebates that may apply to your installation — and we only mention rebates we can verify for your situation.
