HVAC Replacement in Santa Rosa, CA
When the furnace or AC is old, replacing it before it fails gives you time to compare options, including heat pumps, and to get the permit and testing done properly.
Request an HVAC technicianSigns it's time
Frequent repairs, rising energy bills, uneven temperatures, a system that runs constantly in the afternoon heat or old refrigerant types are the usual signals.
Size it right
A load calculation based on the house, its windows, insulation and shade is better than matching the old unit's size. Oversized systems short cycle and waste energy.
Options
Replace the furnace and AC like for like, switch to a heat pump, or add ductless heads for rooms the ducts don't serve well.
Ducts matter
Old attic ducts often leak or are poorly insulated. Sealing or replacing them can matter as much as the new equipment.
Permits and testing
California's energy rules mean most change-outs need a permit, and many require duct leakage testing and third-party verification.
Electrical
Switching from gas to a heat pump can require a new circuit or panel upgrade. Ask early.
Timing
Spring and fall, between heating and cooling seasons, are the easiest times to schedule.
Rebates
Utility and state programs for efficient equipment change often. Ask what's available now.
Get a quote
Ask for equipment, model numbers, duct work, permit and warranty in writing. Send a request and an HVAC technician will get in touch.
Old equipment
Ask whether the quote includes removing old equipment and properly recovering refrigerant from the old AC.
Plan before it fails
Replacing a system on your schedule, rather than during a heat spell, gives you time to compare quotes, check rebates and book the work when crews are less busy.
Ask about noise
Newer outdoor units are quieter, but placement still matters near bedrooms and neighbours' windows.
