Furnace Replacement FAQ for Phoenix

When is the best time to replace a furnace?

Late summer (August–September) is the sweet spot — contractors are less busy, and you'll beat the cold-weather rush.

Is a 95% AFUE furnace worth the upgrade?

In cold climates, the efficiency gain pays back the upgrade premium in 5–8 years through lower gas bills. High-efficiency models run $7,500–$12,000 installed.

Can I switch from oil to gas?

Yes, but it requires gas-line installation, oil-tank removal, and venting changes — typically $6,000–$10,000 beyond the furnace itself.
