AfterHVAC Company in San Lorenzo, CA
HVAC work in San Lorenzo means working on David Bohannon-built tract homes from the 1940s and 1950s that were never designed for central air. Our crew understands what that means in practice: narrower crawl-space ducts, compact floor plans, and cooling retrofits that need real planning, not a box swapped in place. Whether you need a furnace repair on a cold winter night or a full AC installation before summer heat, call (747) 966-3037 and a live person answers, 24 hours a day.
Why San Lorenzo Homes Are Different
San Lorenzo’s housing stock is overwhelmingly composed of post-WWII tract homes built by David Bohannon between roughly 1944 and 1958. These single-story homes, mostly 800 to 1,200 square feet, sit on raised foundations and were built with heating only. Central air wasn’t part of the original design. That means most homes have original narrow duct runs in the crawl space sized exclusively for a central furnace, along with wall furnaces and undersized floor registers that still show up regularly. When we add cooling to these systems, the ductwork almost always needs augmentation or full replacement to handle the new load.
The climate adds another layer. San Lorenzo sits 2 to 3 miles from the bay in the East Bay flatlands, which puts it in a thermal transition zone. Marine air moderates most summer days, but inland heat events and fall Diablo wind conditions routinely push temperatures 15 to 25 degrees above what coastal Oakland or Alameda sees. These homes were never engineered for that kind of sustained heat.
And there’s a final piece that out-of-area contractors often miss: San Lorenzo Village falls under the San Lorenzo Village Homes Association, one of California’s oldest planned-community HOAs. The association enforces architectural guidelines on condenser unit placement, required screening, and visible rooftop equipment. Getting that approval layer right before installation starts prevents permit delays and rework.
Our Main San Lorenzo Services
Most San Lorenzo homeowners call us for one of two reasons: the furnace won’t start during a cold spell, or the house is finally getting central AC after decades without it. Here’s what each involves locally.
AC Repair in San Lorenzo
Most San Lorenzo AC systems are retrofits added years after the house was built, and they fail in predictable ways: undersized return air, strain from a condenser running harder than the ductwork was designed for, and refrigerant leaks at the flare fittings. We diagnose first, show you the problem in plain language, and give you a written price before any work starts. If you’ve got a system struggling through a heat event, AC Repair in San Lorenzo is the page to read next.
Furnace Repair in San Lorenzo
Original and early furnaces in San Lorenzo’s Bohannon tract homes are now decades old, and many still sit in hallway closets or crawl spaces with narrow access. Ignition failures, cracked heat exchangers, and blower motor wear in these tight spaces are the jobs we see most. We carry parts for Trane, Lennox, Goodman, and Rheem systems on our trucks so we can often complete the repair in a single visit. Furnace Repair in San Lorenzo covers what to expect in detail.
AC Installation in San Lorenzo
Adding central air to a 1940s or 1950s San Lorenzo tract home usually means more than installing a condenser. We assess the existing crawl-space ductwork, recalculate the airflow for cooling, and walk you through what needs to change and why. HOA approval from the San Lorenzo Village Homes Association is part of the plan from day one, not an afterthought. AC Installation in San Lorenzo explains the process, the pricing, and the timeline.

What pushes a San Lorenzo repair toward the higher end of these ranges is often the age of the home: corroded ductwork, undersized returns, or an HOA condition that changes how the work must be done.
