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.
A large share of the equipment we service in Mill Valley was installed by a builder to a minimum spec. That usually means an undersized return, a cheap filter rack and a condenser sitting close to a wall.
We recommend two maintenance visits a year in California: one before May through October and one before November through February. It is the single highest-return thing a homeowner can do for equipment life.

Mill Valley94941 HVAC questions, answered
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
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 Mill Valley?
All of them. Our 94941 technicians are trained on American Standard, York, Rheem, Lennox 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.
Are your technicians licensed and insured?
Every technician dispatched into Mill Valley is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
How often should I change my filter in 94941?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Mill Valley with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
