Mount Hermon is a small forested community in the Santa Cruz Mountains between Scotts Valley and Felton, about 19.4 miles southwest of our west San Jose base. Homes sit among tall redwoods on quiet, winding lanes. AdvancedFlow HVAC Contractor helps Mount Hermon homeowners keep steady heat through the cool, shaded months and add cooling when summer warms up.

Under a thick canopy, sunlight is limited and homes can stay chilly well into spring. Many houses here are older and have been added onto over time. Call us with what you are noticing, and we will plan a visit, check the system and suggest options that fit the home and how you use it.


Heat That Reaches Every Room

When a home has been expanded, the original furnace and ducts may not reach the new rooms well. We test airflow and temperatures room by room and recommend changes that bring the whole house closer to the thermostat setting.

Homes Beneath the Redwoods

Limited Sun

Heavy shade keeps homes cool most of the year. Efficient, evenly distributed heat matters more here than in sunny valley homes.

Needles and Moisture

Redwood debris collects on outdoor units and in gutters near equipment. Regular cleaning and good placement help systems last.

Mount Hermon FAQ

Why are my added rooms colder than the rest of the house?

The original ducts may not reach them well. A duct extension or ductless head can help.

Will a heat pump keep a shaded home warm?

Yes, when it is sized for your home and the cooler temperatures under the trees.

How do I protect my outdoor unit from needles?

Keep the area clear and schedule yearly coil cleaning. We can suggest better placement too.

Can you fix ducts in a damp crawlspace?

Yes. We repair, seal and insulate ducts and can replace damaged sections.

Can I add cooling for warm summer days?

Yes. A heat pump adds cooling while also handling heating.

What does a heating tune-up include?

Cleaning, safety checks, airflow testing and an inspection of burners, igniters and controls.
