Is there a Sunnyvale rebate for switching to a heat pump?

There may be. Silicon Valley Clean Energy (SVCE) is Sunnyvale’s electricity provider, and its home rebates page lists Sunnyvale among the communities it serves. As of November 2026, that page says:

• SVCE offers a standard rebate on a heat pump heating and cooling system that replaces a gas furnace or electric resistance heat.
• The City of Sunnyvale funds an extra amount on top when the heat pump replaces gas heat, with a larger extra amount for income-qualified homes.
• No extra steps are needed for the city portion, but the money is available only until it runs out.
• SVCE also offers a rebate on heat pump water heaters.

You may qualify; call us and we’ll check what applies to your home before you commit to a system.

Where are building permits issued in Sunnyvale?

At the One-Stop Permit Center on the second floor of City Hall, 456 W. Olive Ave. Sunnyvale runs its permits through an online system called E-OneStop, where applications, documents, inspections and payments are handled. When we install a new furnace, heat pump, AC or water heater in Sunnyvale, we open the permit there, schedule the inspection and set up any HERS testing that applies. HERS testing is an independent check that a new system meets California’s energy rules.

What have we done for Sunnyvale homeowners?

Sunnyvale project	What we found	What we did
Outdoor AC unit replacement	An aging condenser that ran long and cooled the home unevenly	Removed it and installed a new high-efficiency outdoor unit sized to the home
Duct and dryer vent cleaning	A disconnected dryer vent spreading lint through the crawl space	Cleaned the ducts, cleaned the dryer vent, and reattached and sealed the vent duct

The dryer vent job is a good reminder to look under the house now and then. Lint that escapes into a crawl space is easy to miss.

What do Sunnyvale homeowners ask us?

My outdoor unit is old. Can I replace only that part?

Sometimes. It depends on whether the indoor coil and furnace match the new unit. We check both and explain your options in a free written estimate.

How much is dryer vent cleaning?

$130 for a standard vent and $175 for a two-story home.

And duct cleaning?

$399 covers up to 10 vents, plus $15 for each extra vent. Our Rotobrush system scrubs and vacuums each duct at the same time.
