Replace or repair
A furnace past 15 to 20 years old, with a cracked heat exchanger or repeat part failures, usually costs less to replace than to keep fixing.

Gas furnace replacement and new installs, with venting, gas line and ducts checked first. HAXX quotes a heat pump on the same visit, so you can compare.
A furnace past 15 to 20 years old, with a cracked heat exchanger or repeat part failures, usually costs less to replace than to keep fixing.
A load calculation for the house instead of the old furnace label. An oversized furnace short-cycles, heats unevenly and wears out early.
Flue, combustion air and gas piping checked for the new furnace, including high-efficiency models that vent through PVC.
Same-location swaps and horizontal attic installs, with a proper platform, drain pan, service access and clearances.
Replacing both keeps the furnace and coil matched. A heat pump can also do both jobs in one system.
Mechanical permit pulled, combustion and carbon monoxide checks done, city inspection scheduled.
Gas forced-air furnaces in garages, closets and attics heat most Windsor homes built during the town's 1980s and 1990s growth. When yours is near the end of its life, a planned replacement beats an emergency swap on the first cold night.
Sonoma County winter nights often dip near freezing, especially away from the coast. HAXX runs a load calculation instead of copying the old furnace size, so the new one heats evenly without short-cycling.
Replacing a gas furnace in Windsor is allowed. Clean-air rules for gas heating are tightening across California, so HAXX also quotes a heat pump on the same visit for comparison.
Choosing a heat pump instead? Programs open to Windsor homes include Sonoma Clean Power CARE/FERA bonus. Gas furnace replacements generally do not qualify. Current amounts are on the HAXX rebates page.
A furnace replacement in Windsor needs a mechanical permit. HAXX pulls it, runs combustion and carbon monoxide checks, and meets the inspector.

Yes. Replacing a furnace needs a mechanical permit and a final inspection. HAXX pulls the permit, schedules the inspection and is on site for it.
It depends on the house, the ducts and your electrical panel. HAXX quotes both on the same visit, and heat pump rebates are available to Windsor homes, so you can compare the full cost before deciding.
A straightforward gas furnace replacement starts around $2,500, and a furnace with a new AC around $3,500. The final price depends on size, efficiency, venting, access and permits. You get a written quote before work starts.
Most same-location replacements are finished in one day. Attic installs, venting changes or a new gas line can add a day.
