Gas Furnace Installation en Novato — Preguntas Frecuentes

How long does a furnace last in Sacramento?+

A well-maintained gas furnace typically lasts 15-20 years. Sacramento's mild winters mean less wear compared to colder climates, so your furnace may last toward the higher end of that range with annual tune-ups.

Should I get an 80% or 95%+ AFUE furnace?+

A 95%+ AFUE condensing furnace costs $400-$800 more but uses about 15% less gas per heating cycle. In Sacramento, where winters are relatively mild, the payback period is longer (8-12 years). However, if you plan to stay in your home long-term, the upgrade is worthwhile.

Can I install a furnace in my garage in California?+

Yes, but California code requires the burner and pilot be at least 18 inches above the garage floor. The unit must also be in a FVIR (flammable vapor ignition resistant) enclosure or an approved sealed-combustion model.

Is a permit required for furnace replacement?+

Yes. Sacramento County and most NorCal jurisdictions require a mechanical permit for furnace replacement. HERS testing may be required for duct changes.
