Furnace Replacement in San Leandro, CA

Upgrading your furnace in San Leandro isn't just a home investment; it's a chance to significantly boost your comfort, lower utility costs, and explore modern electrification options. Whether your current system is failing, inefficient, or simply reaching its limits, choosing the perfect replacement—be it a high-efficiency gas furnace or a modern heat pump—comes down to a thorough assessment of your existing system, your home's unique needs, and local considerations like our mild coastal winters and the challenge of salt-air corrosion. Air Flow Pros can help you make the right choice for lasting comfort and savings.

When to consider furnace replacement

Evaluate replacement when one or more of the following apply:

  • System age is 15 to 20 years or more (older heat exchangers and controls become unreliable).
  • Frequent repairs that add up to roughly half of a new system cost.
  • Declining efficiency (old furnaces with 80% AFUE or less vs new models up to 97% AFUE).
  • Uneven heating, cold spots, or chronic short cycling.
  • Safety warnings: soot, persistent carbon monoxide detector events, cracked heat exchanger, or gas leaks.
  • Incompatibility with modern controls, zoning, or a planned electrification move to heat pumps.

Common furnace replacement issues in San Leandro include coastal corrosion on exterior components, undersized or leaky ducts in older houses, and limited roof or closet space for new equipment placement.

Comparing replacement options: high-efficiency furnaces vs heat pumps

High-efficiency gas furnace (pros and considerations)

  • Pros: Very reliable in all conditions, familiar maintenance, high AFUE options (up to ~97%), straightforward plumbing and venting in existing gas homes.
  • Considerations: Still uses natural gas, so long-term cost advantage depends on fuel prices and local decarbonization policies; outdoor corrosion concerns for venting and condensate near the bay.

Heat pump options (air-source, ducted or ductless)

  • Pros: Excellent fit for mild San Leandro winters—modern heat pumps provide comfortable heat at lower operating cost and also cool in summer; eligible for many incentives and federal/state tax credits; reduce on-site fossil fuel use.
  • Considerations: Ductwork condition matters—duct retrofits may be needed; cold-climate models handle occasional cooler nights well but may run more often during very cold snaps; outdoor units require corrosion-resistant finishes near the coast.

Which is right depends on your home’s ductwork, willingness to electrify, and long-term goals for energy bills and emissions.

Estimated energy savings

  • Replacing an 80% AFUE furnace with a 95% AFUE model reduces gas use for the same heat by roughly 18 to 20 percent (95 / 80 ≈ 1.1875).
  • Switching from a gas furnace to a modern cold-climate heat pump commonly reduces heating energy consumption by 30 to 60 percent when measured in delivered heating energy; actual cost savings depend on electricity vs gas rates.
  • Additional savings come from improved controls (programmable or smart thermostats), proper sizing, and duct sealing. In many Bay Area homes, electrification with a heat pump can lower overall annual heating and cooling costs while reducing home carbon footprint.

These are estimates—actual savings vary by home size, insulation, thermostat strategy, and the specific equipment selected.

Replacement and retrofit process (what to expect)

  1. On-site evaluation and load calculation: measure home heat loss/gain, inspect ducts, flue and gas lines, and check electrical capacity.
  2. Equipment selection: size and choose model (high-efficiency gas furnace or appropriately sized heat pump), including indoor air quality add-ons if desired.
  3. Permits and approvals: obtain local permits required by Alameda County/City of San Leandro and schedule inspections.
  4. Removal and disposal prep: disconnect fuel and electrical; recover refrigerant from existing systems if replacing AC or converting to heat pump.
  5. Retrofit work: duct modifications, condensate lines, gas line adjustments or cap-off, electrical upgrades, and mounting outdoor units with corrosion protection near the bay.
  6. Installation and commissioning: install, evacuate/recharge refrigerant (if applicable), test safety controls, airflow, and perform combustion analysis for gas furnaces.
  7. Final inspection and handover: local inspector signs off; receive warranty paperwork and operating instructions.

Install times: straightforward furnace swaps often take 1–2 days; full heat pump installations or conversions with ductwork changes can take 2–4 days or longer depending on complexity.

Responsible disposal of old equipment

Proper disposal protects the environment and may be required for rebates:

  • Refrigerant recovery and documentation for any outdoor units following EPA rules.
  • Recycling metal and components; safe disposal of oil and hazardous materials.
  • Proper gas line decommissioning or cap-off by a licensed technician.
  • Keep disposal receipts—many rebate programs require proof of responsible disposal.

Warranties and extended coverage

  • Manufacturer warranties commonly cover heat exchangers and compressors (length varies—heat exchangers are often covered 10 years, compressors 5–10 years).
  • Parts and labor warranties differ and may be limited unless you purchase extended coverage.
  • Extended warranties or service agreements from contractors provide predictable maintenance and may include priority service and discounted repairs. Check warranty transferability if you plan to sell the home.

Financing and rebate options in San Leandro

  • Federal incentives: tax credits for qualifying heat pumps and electrification under recent federal programs may apply.
  • Local/state incentives: utility rebates through PG&E and Bay Area programs, and state-level rebates for electrification and energy efficiency.
  • Financing options: contractor financing plans, HVAC loans, Property Assessed Clean Energy (PACE) programs, and utility on-bill or low-interest offers are commonly available.
  • Eligibility depends on equipment type, income, and permit documentation—collect manufacturer specs and disposal receipts to support rebate applications.

Typical replacement timeline (example)

  • Day 0–3: On-site evaluation and written proposal.
  • Day 3–10: Final equipment selection and permit submission.
  • Day 10–21: Permit approval window (may vary with jurisdiction).
  • Day of install: Equipment removal, installation, commissioning (1–4 days depending on scope).
  • Day after install: Final inspection and warranty documentation completed.

Long-term benefits and maintenance

A correct furnace replacement improves year-round comfort, reduces hot/cold spots, and can lower utility bills and carbon footprint. Regular maintenance—annual tune-ups, filter changes, and duct inspections—preserves efficiency and warranty eligibility. For coastal San Leandro homes, ask about corrosion-resistant components and protective placement to extend system life.

Replacing your home heating system is both a technical and financial decision. A careful evaluation that includes load calculations, local climate considerations, duct condition, and available incentives will ensure the replacement you choose maximizes comfort, savings, and longevity for your San Leandro home.

Rudy and his son came out and kicked some HVAC butt!! two taps of a screwdriver in the right place and the house is warm again ..  true story. thanks so much guys!! seriously a furnace whisperer

Dustin Y.

Jose helped same day and was able to help me diagnose the problem over the phone, not to mention come out to see it in just two hours it was amazing thank you very much!!

Kristina S.

Local family owned company. Rudy was professional and knowledgeable when troubleshooting my tricky furnace problem. He didn't have all the parts on the truck with him, but got them and returned the same day with a few other guys and got the job done. Thanks Rudy!

Arielle L.

This company really came through for me when my heating stopped working during a November cold spell. They also installed an air conditioning system for me. They are some of the nicest people and run a very professional business.

Meredith G.

Dryer vent installed in timely, efficient manner. Professional engagement, easy appointment process, and punctual. Not sure what these things should cost, but $300 not to have to make a big hole in the side of my house myself felt good to me. Happy to recommend.

Mark H.

These guys were fantastic. Locals who helped us get the best a/c in our house. Super responsive too!
