Recommended Sonoma County HVAC Services by Region

Photo: One Hour Heating and Air Conditioning (2013)

Air conditioning, heating and ventilation (HVAC) services are important for homes throughout Sonoma County. However, depending on which region you live in, there may be particular weather and air quality factors that translate to specific needs. Below, we’ve listed the major regions of Sonoma County and provided general advice for making the most of local HVAC services.

North Sonoma County

Cities: Asti, Black Oaks, Cloverdale, Geyserville, Grant, Healdsburg, Jimtown, Lytton, Mercuryville, Preston, Simi

Sonoma County’s northern region is one of its warmest, especially the eastern portion. For example, Cloverdale’s average summer temperature tends to be in the low 90s, and Geyserville and Healdsburg are only slightly cooler. For this reason, north Sonoma County residents should make sure their air conditioning systems are in good repair prior to the start of summer. The best way to do this is by testing your air conditioner before summer—that way, you’ll know if it’s working properly before you need it. Additionally, it’s important to have your air conditioning system serviced annually by an HVAC professional. To minimize cooling costs, homeowners in north Sonoma County should consider alternate, low-energy cooling solutions like installing whole-house fans or solar panels (the latter of which can lower energy costs for air conditioning by generating solar power).

West Sonoma County

Cities: Barlow, Camp Meeker, Cazadero, Duncans Mills, Forestville, Freestone, Graton, Guerneville, Hurlbut, Monte Rio, Occidental, Rio Nido, Sebastopol, Valley Ford, Venado

Sonoma County’s western region (known by locals simply as “West County”) consists of several, mostly small towns scattered through a heavily forested expanse. The weather in west Sonoma County tends to be fairly mild, with average summer highs in the mid-80s and winter highs in the upper 50s. However, in more heavily forested areas, the shade provided by large redwood trees can make the ambient temperature much cooler than those that are fully exposed to the sun. For this reason, a functioning furnace is important for maintaining comfortable in-home temperatures, particularly during the winter. West County residents should have their heating and cooling systems tested and inspected annually to ensure proper functioning all year long.

Sonoma County Coastline

Cities: Annapolis, Bodega, Bodega Bay, Carmet, Gualala, Jenner, Salmon Creek, Seaview, Sea Ranch, Stewarts Point, Timber Cove, Walsh Landing, Valley Crossing

Sonoma County’s coastline is known for its chilly, breezy year-round weather, due to the perpetual presence of ocean winds. In fact, the average temperature on the Sonoma Coast only varies about 10 degrees throughout the year, with average summer and winter highs in the upper 60s and 50s, respectively. Not surprisingly, residents of these coastal towns depend on their heating systems throughout the year to maintain comfortable indoor conditions; air conditioning, on the other hand, is almost completely unnecessary. Sonoma Coast homeowners should have their furnaces inspected annually by an HVAC professional to ensure proper functionality all year long.

Central Sonoma County

Cities: Cotati, Fulton, Larkfield-Wikiup, Rohnert Park, Santa Rosa, Windsor

Sonoma County’s central region, demarcated by the intersection of Highway 101 and Highway 12, is the site of its most populous city, Santa Rosa, which is home to more than 164,000 residents. All cities and towns in central Sonoma County share a similar climate, with average summer highs in the low 80s and winter highs in the upper 50s. Despite its overall mildness, the weather is prone to variation in all seasons, including infrequent bouts of extreme cold and heat during winter and summer. In these instances (as well as to regulate indoor temperatures in general throughout the year), it’s convenient to have a functional air conditioning, heating and ventilation system in the home.

South Sonoma County

Cities: Boyes Hot Springs, Eldridge, Glen Ellen, Kenwood, Penngrove, Petaluma, Schellville, Sonoma, Two Rock, Vineburg

Sonoma County’s south and southeast regions, while located relatively close to each other, feature varying weather and air quality conditions. For example, in Petaluma, windy weather and an abundance of farmland make allergies and livestock odors an ongoing issue for residents. That’s why it’s important for homes in Petaluma to have good ventilation systems that keep allergens and odors outside. Additionally, residents should routinely change their HVAC system filters to sustain high levels of indoor air quality.

The southeastern portion of Sonoma County includes a string of noteworthy towns consisting of Kenwood, Glen Ellen, Boyes Hot Springs and Sonoma. This area is the warmest portion of Sonoma County’s southern region, with average summer highs in the upper 80s, punctuated by occasional bouts of extreme heat. While the warm weather may be good for the many vineyards situated throughout the region, it can create uncomfortable conditions for local residents. That’s why it’s important for homes in Sonoma and the neighboring towns to have working air conditioning systems. To ensure proper functioning, it’s wise to test your air conditioning system before the summer heat sets in and have it inspected annually by a professional HVAC technician.

Jon Diamond: A Brilliant Opportunity

By James Florence, Diamond Certified Resource Reporter

SANTA ROSA – When Jon Diamond was introduced to the HVAC field by a family member, he had no idea how far it would take him. “I got into the trade through my cousin, who was a union sheet metal worker,” he remembers. “After about a year with the union, I got into residential HVAC retrofitting, where I was lucky enough to get trained on design and estimating. Eventually, I partnered with Curtis Moore and we founded our own company, which continues to specialize in HVAC retrofitting.”

Today, as owner of Moore Solar / Heating / Cooling, Jon says his favorite part of his job is providing opportunities for his employees. “A lot of our employees are at a point where they’re starting families, so I love the fact that we’re able to provide them with careers that have opportunities for advancement. We have something we call the ‘sweet spot,’ which is when we’re able to match an employee with a position that utilizes their natural disposition and talents. When we’re able to get someone to a place where they’re enthusiastic about their job, that’s when the magic happens.”

A resident of Petaluma (where he lives with his wife, Gen, and the younger two of their four children), Jon likes to spend his time outside of work on active pastimes like golf and fishing. “My business partner, Curtis, is a big steelhead fisherman, so I always enjoy joining him for that,” he says. “Also, I’ve recently been on a health kick, so I’ve been hiking a whole bunch, which I really love.” Jon also enjoys spending time with his family, including his two adult sons, 17-year-old daughter and 11-year-old son.

In regard to a professional philosophy, Jon espouses the importance of three words: character, honor and integrity. “Those three words are the foundation of our business,” he affirms. “We believe that if we incorporate those three things on every job and in every decision, the financial aspect will take care of itself. I think a lot of businesses make the fundamental error of basing every decision on getting profits as high as possible. That’s not us—we’re more concerned with creating a healthy, balanced culture that ensures our customers have good experiences and gives our employees the opportunity to have fulfilling careers.”

When asked the first thing he’d do if he were to retire tomorrow, Jon says he’d take some time to recoup from the rigors of running a business. “I would probably do nothing for a couple of months—just spend more time with my family and relax. After that, who knows?”

Charlie Nelson: Taking Things to the Next Level

By James Florence, Diamond Certified Resource Reporter

SANTA ROSA — Following a string of underwhelming occupational experiences, Charlie Nelson had begun to grow disillusioned about his professional future. Fortunately, after being hired as a sales representative for an HVAC service company, he found an opportunity to take things to the next level. “While visiting a jobsite, I would sometimes sit and watch the guys install the equipment,” he recounts. “After a while, I thought to myself, ‘I could do this,’ so I asked the company owner to train me to be an installer. After doing installations for a couple of years, he sent me to school to become a service technician. From there, the obvious next step was to branch off and start my own company, and that’s how Next Level Heating & Air Conditioning Inc was born.”

Today, Charlie says his favorite part of his job is pleasing his customers. “I enjoy seeing the smile on a customer’s face when the job is complete, whether it’s a simple repair or a large installation. When someone has been through a cold winter’s night without their heater, they really appreciate it when you warm things up for them again, and that makes me feel good.”

A lifetime resident of the North Bay, Charlie resides in Santa Rosa with his wife, Sarah, and their five children. “I enjoy the down-to-earth character of the people here,” he says. “Pretty much everywhere you go, you can say, ‘Hi’ to a complete stranger, and they’ll say, ‘Hi’ back. I also love the mild climate…even though it’s not really ideal for my business,” he laughs.

Outside of work, Charlie keeps busy with a variety of family activities. “My kids all play baseball, and I coach their little league teams,” he says. “It takes up a lot of my time, but there’s no greater joy than seeing my kids progress and gain more confidence with each passing season.” In addition to team sports, Charlie and his kids enjoy building and playing with remote-controlled hobby cars, as well as outdoor activities like hiking, bicycling and camping.

In regard to his professional career, Charlie espouses the importance of putting his customers first. “The customer is at the core of everything I do,” he affirms. “When I walk through someone’s door, I consider it my job to not only provide a high-quality service, but to become friends with that person as well. It all comes down to the customer’s best interest, and I think that’s reflected by the repeat business I receive.”

When asked the first thing he’d do if he could retire tomorrow, Charlie says he’d take his family on a big vacation. “We’ve always wanted to go to Europe, so we’d probably go over there for a few weeks and do some sightseeing.”

A: I’d probably go to the past and start doing heating and air conditioning a lot sooner, just because it took me a while to find my professional niche.

Q: What’s your favorite thing to eat for breakfast?
A: Biscuits and gravy.
