Heating and air conditioning service built around Larkspur
Inland valleys hit extreme heat while coastal zones stay mild, so system sizing matters more here than raw capacity. Our Larkspur teams are set up for exactly that: rapid response, flat-rate pricing quoted before work begins, and no surprise overtime charge for nights or weekends.
Because California swings between seasons quickly, a lot of our Larkspur calls come in the first hot or cold snap of the year — systems that sat idle for months and then get asked to run flat out.
If your system is over ten years old and you have had two repairs in the last two seasons, a replacement comparison is usually worth running even if the current unit still runs.

Larkspur94939 HVAC questions, answered
How often should I change my filter in 94939?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Larkspur 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.
Do you offer maintenance plans?
We do. A two-visit plan in California covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
What brands do you service in Larkspur?
All of them. Our 94939 technicians are trained on American Standard, Heil, Mitsubishi Electric, Trane 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.
What does a new system cost in Larkspur?
A complete residential replacement in the 94939 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.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Larkspur 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 causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Larkspur we see algae and dust clogging drain lines constantly during May through October. It is a fast fix but ignoring it ends in ceiling damage.
