The Mill Valley94942 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.
Thermostat reading several degrees off from reality
Refrigerant leak at a flare or coil connection
Short cycling — on and off every few minutes
No cool air, or air that is barely cooler than the room
Breaker trips every time the system starts
Furnace lights then shuts down after a few seconds
Heating and air conditioning service built around Mill Valley
Whether the complaint is weak airflow upstairs, a furnace that will not stay lit, or an outdoor unit that hums but never starts, the process is the same — a proper diagnostic, a written price, then the repair.
In the 94942 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.

Mill Valley94942 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.
Do you service commercial and light commercial properties?
Yes. Around Mill Valley we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Mill Valley see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
What brands do you service in Mill Valley?
All of them. Our 94942 technicians are trained on Lennox, Bryant, Rheem, Amana 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.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Mill Valley, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
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.
