What HVAC problems are most common in Sunnyvale?
The issues we see most in Sunnyvale: Eichler home HVAC challenges, Radiant heat systems, and Adding cooling to older homes. Sunnyvale enjoys moderate South Bay weather, cooler than inland San Jose due to slight bay influence. Summer temperatures reach the upper 80s to low 90s. Winters are mild. The climate supports both heating and cooling needs without extreme demands.
Why won't my AC or heater turn on?
A system that runs but won't cool is often a failed capacitor, low refrigerant, a dirty coil, or a tripped safety switch, while no heat is commonly a bad igniter, flame sensor, clogged filter, or thermostat fault. A proper visit checks refrigerant charge, electrical components, and airflow before quoting any repair.
