Furnace Replacement FAQs
What are the details of the Furnace Lifetime warranty?
When we replace a furnace, the new furnace includes a lifetime heat exchanger warranty. If the heat exchanger ever fails, we replace it at no cost for as long as you own your home. The heat exchanger is the heart of the furnace, responsible for safely transferring heat from the burner to your home’s air, and it’s the single most expensive part to replace. You also get a 10-year manufacturer parts warranty and our multi-year labor coverage for complete peace of mind.
How do I know it’s time for a furnace replacement instead of another repair?
If your furnace is 12 to 15 years old, requires frequent service calls, or has a cracked heat exchanger, replacement is usually safer and more cost-effective than another major repair.
How long does a residential furnace replacement take?
Most gas furnace replacements are completed the same day in about 6 to 8 hours, including safe removal of the old unit, setting the new furnace, reconnecting gas and electrical, and running a full heating-performance test.
Can I upgrade to a high efficiency 96% AFUE furnace when I replace my old 80% unit?
Yes. We offer two-stage and variable speed furnaces up to 96% AFUE. Higher efficiency means lower utility bills and improved comfort with more even heat.
Is a permit required for furnace replacement in California?
Yes. State and local building codes mandate a permit and final inspection for any furnace replacement. We pull the permit, schedule the inspector, and include the fee in your up-front quote.
What size furnace does my home need?
We perform an ACCA Manual J heat-loss calculation that factors in square footage, insulation, window layout, and climate zone. This ensures the replacement furnace is neither undersized (cold rooms and short cycling) nor oversized (higher bills and wear), giving you steady comfort and maximum efficiency.
