AfterHVAC Company in Cotati, CA
Meadowsweet Heating & Air is the HVAC company Cotati homeowners call when they want a straight answer about heating and cooling systems that were never quite designed for the weather this town actually gets. Most Cotati homes date from the 1960s through the 1990s, built for mild coastal air and a central furnace, not for the heat domes and wildfire smoke that now roll through Sonoma County each summer. Add in the Petaluma Gap winds and ductwork sized for heat only, and you get jobs that need a crew who understands how Cotati houses actually behave. Call (747) 966-3037 and you’ll get a live person, day or night.
Why Cotati Homes Are Different
Cotati sits right in the Petaluma Gap wind corridor, where cool Pacific air pours inland and keeps summer afternoons routinely 5–10°F cooler than Santa Rosa just seven miles north. That sounds pleasant until you check the attic. The majority of Cotati’s ranch-style and tract homes from the 1960s–1990s were built with no cooling system at all, single-pane windows, and ductwork sized for a furnace only. Today, a homeowner in Cotati asking for air conditioning often needs more than a condenser dropped next to the house. The ducts frequently can’t carry the added cooling load without being resized or partially re-routed, which is exactly the kind of retrofit work most HVAC companies don’t like quoting. We do.
Then there’s the smoke. Since the 2017 Tubbs and 2019 Kincade fires, Cotati homeowners regularly ask about MERV-13 filtration upgrades and ERV installations whenever a system is being replaced. Before 2017, that conversation barely existed in this part of Sonoma County. Now it’s standard on almost every quote we write here.
Our Main Cotati Services
Cotati homeowners call us most often for air conditioning repair and furnace repair, with AC installation close behind as summer heat events push more of the town toward cooling retrofits. Each of these services has its own Cotati page with full pricing and local details.
AC Repair in Cotati
When an older cooling system fails during a Sonoma County heat event, the complaint is almost always the same: the AC runs but the house doesn’t cool. In Cotati’s retrofit-heavy housing stock, that usually points to a duct system struggling to move conditioned air through sheet metal sized for heat only, not a simple capacitor swap. Our technicians check airflow before condemning equipment, which saves Cotati families from paying for a compressor that wouldn’t have fixed the real problem anyway. Repairs run $150–$650 depending on what’s actually failed. AC Repair in Cotati
Furnace Repair in Cotati
Winter nights in Cotati get cold enough that a dead furnace is a genuine health concern for older residents and young children alike. Our furnace repair work in Cotati focuses on the brands this town’s housing stock actually contains: Goodman, Rheem, York, and a fair number of original furnaces now 25–35 years old. We carry common parts for those brands on our service trucks, which means most repairs finish on the first visit. Furnace repairs run $150–$700. Furnace Repair in Cotati
AC Installation in Cotati
Most AC installations in Cotati are add-on retrofits to furnace-only duct systems, which means the quote has to account for duct resizing, line-set routing through tight ranch-home attics, and proper airflow balancing. We write a fixed price for the complete job, including any duct modifications, before any equipment gets ordered. A typical Cotati AC installation runs $3500–$7500, and we’ll tell you exactly which end of that range your house falls on after a load calculation, not a guess over the phone.

Pricing for HVAC Company in Cotati, CA
| Service | Typical range in Cotati |
|---|---|
| AC repair | $150–$650 |
| Furnace repair | $150–$700 |
| AC installation | $3500–$7500 |
| Seasonal tune-up | $80–$200 |
What pushes a Cotati repair toward the top of those ranges is usually ductwork, not equipment. Homes with original furnace-only ducts, heavily soiled filters from wildfire smoke, or undersized returns take longer to fix because the system itself is fighting a design it was never built for. What never changes is the price you’re told: every Meadowsweet job starts with a written price before work begins, and that’s the price you pay, not a starting point.

FAQs About HVAC Company in Cotati
Most furnace or AC replacement jobs in Cotati require a permit through the City of Cotati Building Division. We pull the permit for you and schedule any required inspections as part of the job. Repairs that swap a failed part for a like-for-like replacement generally don’t need one.
Yes, and we do it while protecting your indoor air. Our Cotati techs keep entry and exit brief, use shoe covers and drop cloths, and follow the C.A.R.E. values code on every visit. If your system needs a filter upgrade or an ERV to handle future smoke events, we’ll explain your options without pushing a sale.
Yes. The Petaluma Gap wind corridor pulls marine air through Cotati that often keeps afternoons 5–10°F cooler than Santa Rosa seven miles north. That’s why so many Cotati homes were built without AC. Heat dome events and wildfire smoke have changed what families need, but the baseline climate here is genuinely milder than the rest of Sonoma County.
If your furnace is down on a cold Cotati night, your AC is struggling through a hot spell, or you’re ready to add cooling to a home that’s never had it, call Meadowsweet Heating & Air at (747) 966-3037 for a free estimate. A live person answers, every time.

What Cotati Customers Say
"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."
- Nadine Oakley"Furnace tune up before winter. He was careful going in and out, closed the gate behind him every time because of the kids, and cleaned up the work area completely. Calm, thorough guy."
