Sonoma—Heart of the Coolest County

Located 40 miles north of San Francisco, there is nowhere like Sonoma County. Wine enthusiasts and tourists often think of Napa Valley as the place for superior vintages and farm fresh foods. They often think the same of Sonoma County. However, Sonoma County also has a rich history as well as a thriving arts and culture community in addition to its reputation as a peer of California wine country.

We at Ongaro and Sons can relate to having a great reputation in one area means that maybe people are unaware of our other accomplishments. In addition to the stellar service provided by fully-vetted, experienced and licensed technicians with no surprises or hidden costs in heating and cooling, Ongaro and Sons also provides a range of plumbing and boiler  services.

Sonoma’s Origins and the Story of the Bear

Many native Americans living in what is now Sonoma—the Coast Miwok, Wappo and Southern Pomo tribes—died of smallpox following the arrival of Spanish settlers in the early 19th century. However, many of the descendants of these tribes are still resident in Sonoma, according to city historian Robert Demler.

In 1823, Father Jose Altimira built the Mission San Francisco de Sonoma, which was under Mexican military control until June 1846, when a group of Americans led a successful rebellion and established the Republic of California. The Republic didn’t last very long and became a U.S. Territory; however, the flag of the rebels and the Republic of California, which portrays a bear, eventually became the state symbol of California. Interestingly, the symbol of the bear derives from an unflattering description of the rebels’ ragged appearance hurled at them by the Mexican defenders— that they looked like “los osos,” or a bunch of bears.

We at Ongaro and Sons wear work clothes that are anything but ragged. Our professional appearance is matched by our certified professional knowledge and dedication to customer service.

Sonoma Arts and Culture

Sonoma has a thriving art community filled with concert venues, art galleries and museums. Broadway World San Francisco twice named Transcendence Theatre Company the annual Theater of the Year. LaHaye Art Center features completed and in-progress work by local artists. The Sonoma Valley Museum of Art showcases a range of metal sculpture and contemporary paintings, and also offers a number of educational programs for students and adults.

Sonoma Restaurants and Wineries

There are too many award-winning wineries to visit in several lifetimes, and each one is unique. Some highlights include:

  • Highway 12 Vineyards and Winery provides Carneros Chardonnay, handmade dog toys and unique picture frames.
  • Buena Vista Winery, founded in 1857 as California’s first premium winery, produces 100,000 cases of wine a year.
  • Three Sticks at the Adobe is an 1842 adobe home complete with antique china, 1800s artifacts and wine tasting paired with caviar, crème fraiche and capers.
  • The B and V Whiskey Bar and Grille specialize in brisket smoked for 12 hours over a French oak barrel.
  • Wit and Wisdom is a relatively new wine country tavern featuring American comfort food and a robust wine list, not to mention a bocce court.
  • Valley Bar and Bottle advertises “California home cooking” featuring season produce and organic wines.

Sonoma’s Comfortable Climate

June, July and September are the most pleasant months in Sonoma; January and December the least.  Although if you came from Minnesota, you’d hardly call winter California weather unpleasant.  Best Places rates Sonoma with a comfort index 8.4 out of 10.

Comfortable as it is, Sonoma residences and businesses still need effective cooling and heating systems to stay comfortable. Which is why our customers in Sonoma trust Ongaro and Sons to provide no-risk, guaranteed service.

Sonoma County is part of a climate action plan called Climate Action 2020 and Beyond to reduce greenhouse gas emissions in the region. Ongaro and Sons offers a variety of best energy practices both to prepare for winter heating and summer air conditioning.

Sonoma Air Quality and Protection

Sonoma County is served by two air quality districts that provide resources related to air quality and community health. The Community Air Protection Program develops strategies to measure air pollution and reduce its health impacts.

When outside air is potentially dangerous, Ongaro and Sons can offer products you need to breathe easier indoors.

Seasonal allergies are a constant, if less dangerous, irritant. For most of us, it is annoying to endure a runny nose or headache caused by allergies. For some, however, allergies can pose a significant health risk.

Ongaro and Sons offers a set of tips to help relieve your allergy suffering. Regular maintenance of your heating and cooling system, such as periodically changing air filters, can make breathing at home more comfortable.

Sonoma Wildfire Threat

In fall of 2020, some 64 wineries in the area of Sonoma County were threatened by spreading wildfires. California has experienced a tremendous increase in wildfires, the smoke from which further contributes to both poor air quality and threats to resident health. Smoke, of course, is an irritant to lungs and a significant source of air pollution. Ongaro and Sons does have some products that can at least help Sonoma County residents breathe easier indoors.

Duct Cleaning, Repair and Replacement

Central air conditioning and heating are the top energy consumers in most California homes, so ensuring the efficiency of your entire HVAC system can yield big improvements in energy efficiency. When we think about saving energy, we usually focus on the furnace and air conditioner units, but a leaky duct system can reduce your climate control system’s efficiency 20 to 30 percent. These leaks also  bring unwanted dust, unconditioned outdoor air and humidity into your living space and take money straight out of your wallet.

If your home is over seven years old, have your ducts professionally tested by one of our certified Home Energy Rating System (HERS) technicians via an energy audit. If needed, we can do a thorough and effective cleaning, repair or even replace leaky ductwork.

Indoor Air Quality

Ongaro and Sons puts the “V” back into the HVAC. Ventilation is the process of bringing fresh air into your home to replace stale air filled with indoor pollutants such as cooking smells, pet odors and/or tobacco. Proper ventilation is not only key to the efficiency of your home heating and cooling system, but to your indoor air quality and you and your family’s health. While air filters and air fresheners remove particles from circulating, they don’t bring in fresh air. One simple way to correct this is to open doors and windows, but this is not always practical. It also allows outside allergens and pollutants into the house.

Ongaro and Sons offers a number of solutions to increase the quality of your indoor air, including everything from a filtration system to a complete home purification system and fresh air exchanger system. We’re a family-owned business. No one knows better than us the importance of protecting the health of you and your family.
