Furnace Installation in Greenville, SC

Igniter replacements are a common, relatively affordable repair — typically $200-$400. A cracked heat exchanger is a different story entirely: it’s a safety issue (potential carbon monoxide leak) and the repair often costs $1,500-$5,000+ for the part and labor. On a furnace over 15 years old, a cracked heat exchanger usually means it’s time to replace rather than repair. Airflow issues — dirty blowers, collapsed ducts, clogged filters that have led to secondary damage — vary widely. We diagnose the root cause, not just the symptom, and give you honest advice on repair vs. replace based on your system’s age and overall condition.

A gas furnace installation typically ranges from $4,500 to $12,000+, while heat pump systems run $6,000 to $15,000+ — with variable-speed and dual-fuel systems at the higher end. Heat pumps have a higher upfront cost but offer both heating and cooling in one system, which can offset the investment. The total price depends on system size, efficiency rating, ductwork condition, electrical requirements, and whether gas line work is needed. We evaluate all of this during our in-home assessment and present options at multiple price points.

Gas furnaces are generally less expensive to purchase but require a gas line and proper venting. Electric heat pumps have higher equipment costs but lower operating costs in moderate climates like Upstate SC, and they qualify for federal tax credits when they meet efficiency thresholds. Higher efficiency ratings (AFUE for furnaces, HSPF2/SEER2 for heat pumps) mean higher upfront equipment cost but lower monthly utility bills. We help you calculate the breakeven point — sometimes a higher-efficiency unit pays for the difference in 3-5 years, sometimes it doesn’t. We give you the math, not just the sales pitch.
