Frequently Asked Questions
Does salt air affect water heaters and HVAC equipment in Sausalito?
Yes. Salt air near the bay speeds up corrosion on outdoor units, gas vents, pipe fittings and electrical connections. Regular maintenance lets a technician catch rust early, before it turns into a leak or a failed part.
Why is the water pressure low in my older Sausalito home?
Common causes are aging galvanized pipes narrowed by buildup, a hidden leak, a failing pressure regulator or a partly closed shut-off valve. A plumber can test the pressure and find the cause before recommending a repair.
Can a hillside Sausalito home switch from a gas furnace to a heat pump?
Usually, yes. A technician checks your electrical panel, your ductwork and where the outdoor unit can sit on a sloped lot. Ductless mini-splits are often a good fit for multi-level homes without ducts.
Is a tankless or heat pump water heater a good fit for a Sausalito condo or small home?
Both save space compared with a large tank. Tankless units need enough gas or electrical capacity, and heat pump water heaters need some open air around them. We look at your space and your hot water use before recommending one.
Do I need a permit to replace a water heater or electrical panel in Sausalito?
Yes. Water heater replacements and electrical panel upgrades need a permit. We handle the permit process for the jobs we do.
