AfterHVAC Company in Sonoma, CA
Meadowsweet Heating & Air is an HVAC company serving Sonoma, CA with repair and installation work calibrated to the valley’s unusual climate. Sonoma sits at the northern edge of San Pablo Bay’s marine push, so summer mornings often start under fog at 55°F while afternoons climb past 95°F. That 40-degree daily swing changes how equipment should be sized, how ductwork performs, and how quickly a repair call matters. Our Sonoma crews arrive with a written price before any work starts, and every job is backed by the 365-Day Done Right Promise. If you need a repair or a new system, call (747) 966-3037 and a live person answers, day or night.
Why Sonoma Homes Are Different
Sonoma’s housing stock leans heavily toward pre-1980 California ranch homes and wood-frame bungalows, particularly around the historic Plaza and east along the Sonoma Valley corridor. Many of these homes were built around wall heaters rather than central forced air, so when a system goes in today, it often means adding or correcting ductwork, not just swapping a unit. We routinely find galvanized ducts that were undersized for the cooling loads Sonoma actually sees in July and August.
The valley’s microclimate adds another layer. Summer afternoons can spike into the 95-105°F range during heat events, but the marine inflow from San Pablo Bay pulls temperatures back down sharply at night. Single-stage systems struggle with that pattern, running short cycles that leave humidity behind. Variable-capacity equipment handles it far better, and we recommend it more here than in flatter, more coastal areas. Winter brings valley radiation fog that lingers through the morning and raises moisture levels inside older duct runs. That feeds mold growth around evaporator coils and inside return plenums, which is why coil cleaning and filtration upgrades are a consistent part of our Sonoma workload from November through February.
On the valley slopes, wine-country estate properties introduce an entirely different tier of work: wine cellars that need year-round temperature and humidity control, detached casitas with separate zones, and long duct runs through unconditioned crawl spaces. These jobs rarely show up in neighboring suburban markets, and they reward careful load calculation over rule-of-thumb sizing.
Our Main Sonoma Services
Most Sonoma homeowners call us first for one of two reasons: a cooling system that stopped working during a heat spike, or a furnace that failed on a foggy winter morning. Each service has its own dedicated Sonoma page below.
AC Repair in Sonoma
When an air conditioner fails during a 100°F Sonoma afternoon, the house heats up fast, and kids and pets feel it first. We diagnose the system, show you the written price before any repair begins, and carry common parts for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard on the truck. Sonoma’s short, intense cooling cycles mean capacitors, contactors, and condenser fan motors work harder than they would in milder climates, so those are the repairs we see most often. AC Repair in Sonoma covers what to expect in detail.
Furnace Repair in Sonoma
Sonoma winters are mild by national standards, but valley fog keeps mornings damp and cold enough that a failed furnace is uncomfortable within hours. We repair gas and electric furnaces, check heat exchangers for cracks, and address the humidity-related issues that fog season brings to older duct systems. Every repair includes shoe covers, drop cloths, and a photo of the clean-up before we leave. If your furnace is short-cycling or making noise, Furnace Repair in Sonoma walks through what a typical visit looks like and what parts cost.
AC Installation in Sonoma
A new system in Sonoma is rarely a simple changeout. Many older ranch homes need duct remediation before the equipment can perform, and the climate calls for multi-stage or variable-speed units that can handle the valley’s 40-degree daily swing without short-cycling. We provide a fixed, written price before ordering equipment, schedule a set install date, and handle any rebate or financing paperwork. AC Installation in Sonoma explains sizing, equipment options, and what a full replacement costs in the local market.

What Sonoma Customers Say
"New system install. They protected the hallway floor all the way to the attic and vacuumed after. Worked quietly around my work calls. Not a trace left behind."
- Rosalind Okeke"AC repair in July. The tech laid a mat down by the indoor unit and wore booties through the house. Fixed it fast and left zero mess. Quiet and kind, good with our nervous dog too."
- Delia Frost"Good repair and a very tidy, respectful tech. The appointment window was wide and he came near the end of it, but he texted ahead. Work itself was clean and done right."
