Furnace Replacement Questions
How much does furnace installation cost in Dallas?
Furnace installation in Dallas typically costs between $3,500 and $10,000 depending on the system type and efficiency. Standard efficiency gas furnaces (80% AFUE) start around $3,500-$5,500 installed, while high-efficiency models (95%+ AFUE) range from $5,500-$10,000. We provide free in-home estimates with detailed written quotes so you know exactly what you’re paying.
How long does furnace installation take?
Most furnace replacements take 4-8 hours to complete in a single day. This includes removing your old unit, installing the new furnace, connecting all gas and electrical lines, testing the system, and walking you through operation. More complex installations involving ductwork modifications or relocating the unit may take longer.
What size furnace do I need for my home?
Furnace size depends on your home’s square footage, insulation, windows, and climate. For a 2,000 sq ft home in Dallas, you’ll typically need an 80,000-100,000 BTU furnace. We perform Manual J load calculations to determine the exact size—an oversized furnace short-cycles and wastes energy, while an undersized one can’t keep up on cold days.
Should I repair or replace my furnace?
Use the $5,000 rule: multiply your furnace’s age by the repair cost. If the total exceeds $5,000, replacement makes more sense. For example, a 15-year-old furnace needing a $400 repair (15 × $400 = $6,000) is a good replacement candidate. Also consider efficiency—a new 95% AFUE furnace can cut heating costs by 20-40% compared to an older 80% model.
Do you offer financing for new furnace installation?
Yes! We offer flexible financing through Synchrony and Hearth with 0% interest options for qualified buyers. Get your new furnace installed now and pay over time with affordable monthly payments. Many homeowners finance their installation for $100-$200/month. Ask about current promotions when you schedule your free estimate.
What furnace brands do you recommend?
We install and recommend Trane, Carrier, Lennox, Goodman, Rheem, and American Standard—all proven brands with excellent reliability and warranty coverage. The best choice depends on your budget, efficiency goals, and home requirements. We’ll discuss the pros and cons of each option during your free consultation so you can make an informed decision.
