San Mateo County covers the Peninsula between San Francisco and Santa Clara County, plus the rural coastside beyond the Santa Cruz Mountains. Its central Peninsula cities and coastal towns are about 20 to 30 miles from our west San Jose base. AdvancedFlow HVAC Contractor helps homeowners throughout these areas with furnaces, heat pumps, air conditioning and ductwork.

Heating is the main need for many San Mateo County homes, especially near the fog-cooled coast. Inland Peninsula neighborhoods still get warm spells that make cooling worth having. Reach out with your city and what is happening, and we will set up a visit.
