HVAC Maintenance in Sonoma, CA: What to Expect
Sonoma sits in wine country roughly 55 miles north of San Francisco, where marine air moderates summer heat but occasional inland pushes still send temperatures past 100 F. Most pre-Tubbs Fire homes here lack air conditioning entirely, and heating remains essential for five to six months each year as winter lows hover near 37 F with roughly 30 inches of rain falling between October and April. Eleven contractors serve the area with an average rating of 4.5 stars across 261 reviews, and two offer around-the-clock service for emergencies. For homeowners prioritizing system longevity, professional HVAC Maintenance in Sonoma has become a practical investment rather than a reactive expense.
