Know your Sunnyvale house

Eichler homes often have radiant heating pipes in the slab. Many homes are Eichler or ranch houses from the 1950s and 1960s.

Murphy Avenue is the historic downtown street. Many mid-century homes have ducts in a crawl space or attic that were never sealed, and leaks there waste a lot of heated or cooled air. The Heritage Park Museum keeps an apricot orchard from the city's farm years.

Many older homes near the Bay were built without central air, and ductless mini-splits are a popular way to add cooling. Caltrain stops at Sunnyvale and Lawrence stations.

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 Sunnyvale Community Development Department, which the installer normally pulls.

Who runs what: the City of Sunnyvale for water, the city's Water Pollution Control Plant for wastewater and the City of Sunnyvale Community Development Department for permits. Las Palmas Park is known for its Easter Island-style sculptures. Lockheed has had a campus in Moffett Park since the 1950s.

What usually goes wrong

A few signs it's time for a heating and cooling company:

  • High energy bills without explanation
  • No heat or uneven heat between rooms
  • AC blowing warm air

What to have ready

Write down the thermostat setting and what the room temperature actually reads.

Check whether anything is still under a manufacturer or builder warranty.

How we connect you

What people ask us

Why is my AC freezing up?

Low airflow from a dirty filter or blocked vents is a common cause, and low refrigerant is another. Turn the system off to let it thaw and call a tech if it happens again.

Do you cover Washington Park and Birdland?

Yes, as long as a pro is available. Sunnyvale ZIP codes 94085, 94086, 94087, 94089 are in range, and that includes Washington Park, Heritage District, Ortega Park and Fair Oaks. Share the street name when you call so we can check the right part of town.

How often should I change the filter?

Every one to three months for most homes, more often with pets or allergies. A clogged filter strains the system.

What should a heating and cooling company know about homes in Sunnyvale?

Sunnyvale grew from fruit orchards into a center of the tech industry. The city runs its own wastewater plant near the Bay. Afternoon breezes off the Bay are common in summer. Mention your street and the age of the house when you call.

Who issues permits for HVAC service work in Sunnyvale?

Permits in Sunnyvale go through the City of Sunnyvale Community Development Department. Not every repair needs one, so ask the heating and cooling company whether yours does when you get the quote.

Keep pets in another room while the pro works.

VendorReach doesn't employ technicians or own trucks. Whoever comes out is an independent heating and cooling company working for themselves, not for us. It's fine to say no if the quote doesn't sit right. The pro gives you a price before any work starts, and it's your call whether to go ahead.
