Utilities, permits and licensing
In California, licenses for heating and air conditioning contractors come from the Contractors State License Board. Replacing a furnace, boiler or central air system usually needs a mechanical permit from the City of Livermore Building Division, which the installer normally pulls.
Water comes from Livermore Municipal Water or Cal Water, both buying from Zone 7 Water Agency. The Greenville Fault runs along the east side of the valley. Wastewater from homes here goes to the city's Water Reclamation Plant, and permits run through the City of Livermore Building Division. Summer highs often reach the 90s.
What Livermore housing means for HVAC service
The Livermore Valley has more than 50 wineries. Sandia National Laboratories has a campus here.
Springtown has homes from the 1960s. Original ductwork in mid-century houses tends to leak at the joints. Sealing it can make a noticeable difference in comfort. Most homes sit on slab foundations.
Inland heat waves push older AC units past their limits, and wildfire smoke days make better filtration a common request. Downtown has older homes near First Street.
What to have ready
Find the model number on your furnace, boiler or outdoor unit and have it ready when the tech calls.
Have a rough idea of the age of the equipment or fixture involved.
