The Repair-vs-Replace Decision
Whether to fix or replace comes down to age, the cost of the repair against a new system, and how the unit has been running overall. A one-off failure on a newer system is a clear repair; repeated breakdowns on an aging one, in a climate of mild, dry summers and wet, temperate winters, usually signal it is time. Be wary of anyone jumping to replacement without showing why the repair does not pencil out.

Answers
Frequently Asked Questions
Why will one room not reach the thermostat setting?
Uneven temperatures usually point to ductwork, leaks, imbalance, or undersized runs, rather than the unit itself. It is one of the most common and most overlooked issues, and a good tech checks airflow before blaming the equipment.
How do I avoid being overcharged?
Get the estimate itemized, ask what happens if the first fix does not hold, and be cautious of anyone quoting major work before diagnosing. A second opinion is cheap insurance on any large repair or replacement.
What should I expect to pay for HVAC around Mill Valley?
It depends on the actual fault, the system's age and type, and whether it is an after-hours call. A worn capacitor and a failed compressor are very different prices. Insist on an itemized estimate rather than a single all-in figure so you can see what is driving the number.
Is it worth repairing an older system?
A useful rule of thumb: if the unit is past ten to fifteen years and the repair is a large fraction of replacement cost, replacement often wins, especially in CA, where mild, dry summers and wet, temperate winters keep the system working hard. A straight contractor will show both options with real numbers.
How often does this need a tune-up?
Once a year at minimum; twice, heating in fall and cooling in spring, is ideal where both ends see demand. In Mill Valley, an annual check plus attention to air filtration handles most of what this climate asks.
