The Cotati94931 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
Furnace lights then shuts down after a few seconds

Heating and air conditioning service built around Cotati
Serving Cotati and the wider Sonoma County area, our crews carry the common failure parts on the truck — capacitors, contactors, igniters, flame sensors, motors and filters — so the first visit is usually the last one.
In the 94931 area we see a lot of attic-mounted air handlers. Attic heat soak in summer and cold-soak in winter both shorten component life and make insulation checks part of a proper diagnosis.
Peak cooling demand here runs May through October. Booking a tune-up in early spring means you are not competing with the whole neighbourhood for a tech in July.

Cotati94931 HVAC questions, answered
Do you charge extra for nights, weekends or holidays?
No. Our pricing in California is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
What brands do you service in Cotati?
All of them. Our 94931 technicians are trained on Trane, York, Daikin, Rheem and essentially every other residential brand sold in California, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in California, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
How quickly can a technician get to Cotati?
For the 94931 service area our target response time is 2-4 hours from the moment dispatch confirms your address. Real-world timing depends on the day — the first sustained heat or cold snap of the season is always our busiest period — but we hold technicians locally specifically so that window is achievable rather than aspirational.
How much does an HVAC service call cost in 94931?
A diagnostic visit in Cotati typically runs $75 to $150, and that fee is usually applied toward the repair if you approve the work. Repair prices are quoted as a flat rate before we start, so the number you approve is the number you pay regardless of how long the job takes.
What does a new system cost in Cotati?
A complete residential replacement in the 94931 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
