Frequently Asked Questions

Who does reliable AC repair near me in San Anselmo?

John Owens Services has repaired and installed cooling systems for San Anselmo homes since 1986 and is fully licensed (CA #501853). We offer same-day AC repair whenever possible, with trucks stocked to fix most failures on the first visit.

My older San Anselmo home has no ductwork — what are my HVAC options?

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.

How often should I schedule AC maintenance?

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.

Do I really need AC in San Anselmo?

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.

Why is my AC running but not cooling my San Anselmo 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.

Why is my air conditioner leaking water?

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.

Can I add central AC to a house that was built without air conditioning?

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.

Can I install air conditioning in a home with limited attic space?

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.

Should I replace my ductwork when installing a new AC?

If your ductwork is old, damaged, or not properly sized to your new AC system, it is best to have it replaced.
