When winter creeps in, nothing matters more than a reliable, energy-efficient heating system. Yet most homeowners underestimate the full cost to install a furnace because they only consider the sticker price on the unit itself. Labor, permitting, ductwork modifications, local code upgrades, and disposal fees all add up quickly. At CountBricks, we use real-time material databases and AI-driven labor benchmarks to generate accurate, line-item estimates so you can budget with confidence before the first wrench turns.
• Equipment type and efficiency rating
• Existing duct and gas line conditions
• Labor complexity and crew size
• Permit, inspection, and code compliance fees
• Post-installation testing and disposal requirements
A basic single-stage 80% AFUE gas furnace might cost $1,200 for the unit, but a high-efficiency 97% AFUE variable-speed model can exceed $3,000. CountBricks automatically pulls current wholesale prices from our material cloud, ensuring your estimate reflects what suppliers charge today, not six months ago.
Older homes often need duct resizing or gas line upsizing. A simple reconnect can be as low as $300, while major duct modifications may add $1,200–$2,500. CountBricks AI blueprint takeoffs analyze your floorplan to flag undersized runs before install day, preventing costly surprises.
Labor isn’t just time; it’s skill level and safety risk. Tight crawlspaces or attic installs lengthen the timeline and require additional safety gear. Our live voice estimator captures crew notes in real time, translating them into labor multipliers that fairly compensate technicians while keeping your budget transparent.
Municipal fees vary widely. In Minneapolis, a mechanical permit averages $150–$250, but older neighborhoods may mandate asbestos testing or combustion-air upgrades. CountBricks’ local code database auto-populates these line items so your proposal passes inspection the first time.
Disposing of an old furnace and commissioning the new one can run $200–$450. Our estimates break this out so you understand exactly where every dollar goes.
• Entry-level replacement (80% AFUE, minimal duct work): $4,000–$5,500
• Mid-grade upgrade (92% AFUE, some duct tweaks): $5,800–$7,200
• High-efficiency overhaul (97% AFUE, major redesign): $7,500–$11,000
These figures include equipment, labor, permits, and disposal, generated from thousands of CountBricks residential projects logged in our platform. Your home’s unique conditions ultimately set the final number—but our AI narrows the range before a technician sets foot on site.
Our estimator joins you on a brief video call, asks guided questions, and records measurements verbally. Within seconds, the CountBricks engine translates that conversation into a scoped project file.
If you have digital plans, upload them at CountBricks.com/services. Our takeoff module traces ducts, returns, and equipment closets automatically, outputting exact material counts.
Supplier APIs feed live equipment costs. Regional wage data adjusts labor instantly, so your quote reflects today’s market, not last season’s flyer.
Once the scope is locked, CountBricks compiles a branded, homeowner-ready proposal—complete with payment schedules and warranty options—ready to e-sign on any device.
• Schedule installs during shoulder seasons to leverage off-peak labor rates.
• Combine furnace and A/C replacement for shared labor efficiencies.
• Opt for sealed combustion models to reduce expensive fresh-air retrofits.
• Claim utility rebates; CountBricks auto-calculates eligible incentives in your quote.
A high-efficiency furnace may cost more upfront, but CountBricks ROI calculators show payback in as little as five years when factoring energy savings and rebates. Flexible financing options, displayed directly in your quote, turn large capital outlays into manageable monthly investments.

The question isn’t “What’s the average cost to install a furnace?”—it’s “What will it cost in my home, today?” CountBricks delivers that answer with unmatched speed and accuracy. Start your project at CountBricks.com/consultation and take the guesswork out of staying warm this winter.

The Martinez family owned a 1980s split-level with an outdated 80% AFUE furnace consuming far too much gas. They contacted CountBricks for an estimate after two other contractors gave them “ballpark” numbers.
1. A five-minute video call captured measurements of the mechanical room and supply trunk.
2. The homeowner emailed a PDF floorplan. CountBricks’ takeoff tool auto-traced 162 linear feet of ductwork in under three minutes.
3. Our AI flagged a restrictive 4-inch gas line. The estimator added a new ¾-inch run with the correct fittings, instantly updating material and labor costs.
• High-efficiency 96% AFUE, two-stage furnace
• Gas line upsized 27 feet
• Permit and disposal included
Total: $6,850—$1,200 lower than the lowest competing quote, thanks to accurate material counts and optimized labor scheduling.
After installation, gas bills dropped 28%. The CountBricks client portal now tracks their energy savings against the projected ROI curve generated in the original proposal, proving the numbers weren’t just sales talk.
• Clear a 4-foot path to the mechanical room to reduce labor time.
• Ask CountBricks to bundle smart thermostat setup; combined programming cuts call-backs.
• Review rebate paperwork in advance—our portal pre-fills utility forms so you can submit them the same day the inspector signs off.
