Frequently Asked Questions
How much does furnace installation cost in Houston?
Furnace installation in Houston costs $2,500-$6,500 for a standard gas furnace. High-efficiency (96%+ AFUE) models cost $4,000-$8,000. Electric furnace installation runs $1,500-$4,000.
How long does a furnace last?
Gas furnaces last 15-20 years with annual maintenance. Electric furnaces last 20-30 years. If your furnace is 15+ years old, frequent repairs, or heating unevenly, replacement is usually more cost-effective than repair.
Gas vs electric furnace — which is better?
Gas furnaces heat faster, cost less to operate, and work well in cold climates. Electric furnaces are cheaper to install, last longer, and require no gas line. Choose based on utility costs in your area and climate severity.
