Replace or repair

New furnace,
sized and installed right.
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.
Sized, not copied
A load calculation for the house instead of the old furnace label. An oversized furnace short-cycles, heats unevenly and wears out early.
Venting and gas line
Flue, combustion air and gas piping checked for the new furnace, including high-efficiency models that vent through PVC.
Attic, closet or garage
Same-location swaps and horizontal attic installs, with a proper platform, drain pan, service access and clearances.
Furnace and AC together
Replacing both keeps the furnace and coil matched. A heat pump can also do both jobs in one system.
Permits and safety checks
Mechanical permit pulled, combustion and carbon monoxide checks done, city inspection scheduled.
HAYWARD DETAILSFurnace replacement
Furnace replacement
in Hayward.
Most of Hayward's 1950s and 1960s tract homes still heat with a gas furnace. When yours is near the end of its life, a planned replacement beats an emergency swap on the first cold night.
01
Sized for Hayward homes
East Bay winters run from mild in the flatlands to properly cold in the hills. HAXX runs a load calculation instead of copying the old furnace size, so the new one heats evenly without short-cycling.
02
Gas furnace or heat pump
Replacing a gas furnace in Hayward is allowed today. Bay Area Air District rules limit sales of new gas furnaces starting in 2029, so this may be the last gas furnace in the house. HAXX quotes a heat pump on the same visit.
03
Rebates if you go electric
Gas furnace replacements generally do not qualify for rebates. Heat pump programs and amounts change often; the current list for Hayward is on the HAXX rebates page.
04
Permit and safety
A furnace replacement in Hayward needs a mechanical permit. HAXX pulls it, runs combustion and carbon monoxide checks, and meets the inspector.

GOOD TO KNOW
Furnace Installation in Hayward: questions, answered.
Do I need a permit to replace a furnace in Hayward?
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.
Should I replace my furnace with a heat pump in Hayward?
It depends on the house, the ducts and your electrical panel. HAXX quotes both on the same visit, so you can compare the full cost before deciding.
How much does furnace replacement cost?
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.
How long does a furnace installation take?
Most same-location replacements are finished in one day. Attic installs, venting changes or a new gas line can add a day.
Can I still install a gas furnace?
Yes. Replacing a gas furnace is still allowed in Bay Area homes. Rules are moving toward zero-emission heating, so HAXX also quotes a heat pump on the same visit.
