Ductless mini-splits are usually the best fit for the town’s early-1900s bungalows and hillside homes, giving you quiet, zoned cooling without adding ducts. We size and install them to handle the rooms that actually overheat in the Ross Valley.
Once a year, ideally in spring before the inland heat arrives. Annual AC maintenance keeps efficiency up, catches small issues early, and is especially worth it during smoke season when you’re relying on the system with the windows closed.
More homeowners do every year — San Anselmo runs warmer than coastal Marin because the valley misses the marine fog, and summer afternoons in town can get genuinely hot. We help you choose right-sized, efficient cooling for your specific home.
Your thermostat settings could be incorrect, a breaker could have tripped that shut down the condensor and allows the fan to blow uncooled air, or your air filters could be clogged.
An AC leaking water can be due to a blocked drain line, clogged air filters, or frozen coils drippng water into the drain pan and making it overflow.
You can do this easily if your home has existing ductwork where an AC can be added to the furnace. If there is no ductwork, you can go with efficient options like ductless mini-splits, or you can have traditional ductwork installed.
Yes, there are many compact AC unit options when you have limited space, including ductless mini-splits that only require a small outdoor unit that connects to several small wall units indoors.
If your ductwork is old, damaged, or not properly sized to your new AC system, it is best to have it replaced.
