Bradford recommends replacing your furnace when it's 15+ years old, requires a repair costing more than 50% of replacement cost, or has a cracked heat exchanger (a safety issue). In Arizona, furnaces run less than in cold climates, so a well-maintained unit can last 20–25 years. Bradford offers a free second opinion on any replacement recommendation.

Furnace sizing in Arizona is based on Manual J load calculation — not just square footage. A typical 2,000 sq ft Surprise home needs a 60,000–80,000 BTU furnace. Bradford performs a proper load calculation before recommending a system to avoid oversizing (short cycling) or undersizing (inadequate heating).

AFUE (Annual Fuel Utilization Efficiency) measures how much of the fuel converts to heat. An 80% AFUE furnace loses 20% up the flue; a 96% AFUE loses only 4%. In Arizona where heating costs are low, the payback period for the higher-efficiency unit is 8–12 years. Bradford recommends 80% AFUE for most Arizona homes unless you heat heavily.

Bradford offers 0% financing for up to 60 months on new furnace installations through approved credit. Monthly payments on a $3,500 furnace replacement would be approximately $58/month with 0% financing. Ask about current promotions when you call (623) 624-6246.

APS offers rebates of $50–$150 for high-efficiency furnace replacements (96% AFUE). SRP offers similar rebates. Bradford can help you identify and apply for applicable rebates as part of the installation process. Rebates are subject to change — call (623) 624-6246 for current availability.

A standard furnace replacement takes 4–6 hours for Bradford's crew. The old unit is removed, the new unit installed and connected to existing ductwork and gas lines, and the system is tested and commissioned. Most installations are completed in a single day.
