A cold garage limits year-round use, reduces indoor comfort and can even stress HVAC equipment connected to the living space. Installing a furnace in the garage solves these issues by delivering controlled heat where it is needed most. CountBricks specializes in turning under-utilized garages into comfortable, productive zones while keeping energy bills in check. Our AI-powered estimating platform instantly converts your voice instructions into detailed cost breakdowns, material lists and professionally formatted quotes.
The International Residential Code (IRC) treats a garage furnace differently from a living-space furnace. Clearances to vehicles, ignition source elevations and combustion-air provisions all change. CountBricks project managers stay current with every local amendment so you never face inspection surprises.
• Minimum 18-inch ignition source height to avoid fuel vapors
• Sealed-combustion models required when the garage is also a workshop storing volatile chemicals
• Dedicated GFCI electrical circuits and condensate disposal when using high-efficiency units
• Fire-rated vent penetrations between the garage and living area
1. Forced-air gas furnaces – highest output for large, detached garages
2. High-efficiency condensing furnaces – lower operating cost and sealed combustion; ideal when garage adjoins the house
3. Ductless gas unit heaters – quick install, minimal footprint but limited zoning control
4. Electric furnaces – no combustion venting, perfect where gas service is unavailable
CountBricks engineers evaluate square footage, insulation levels and planned usage. Our blueprint takeoff tool measures wall assemblies directly from your PDFs in seconds, then recommends a properly sized unit, reducing overspend on both equipment and utilities.
1. Speak your project: “Install a 60,000 BTU sealed-combustion furnace in my 24×30 attached garage.”
2. AI Estimate: CountBricks instantly generates a line-item proposal with real-time material pricing, labor hours and permit allowances.
3. On-site verification: A CountBricks technician confirms gas line distance, vent route and electrical capacity.
4. Schedule & procurement: Our platform reserves crew time and orders materials so everything arrives just-in-time, not weeks early clogging your driveway.
5. Installation & inspection: Certified installers follow the digital checklist created from your estimate. Pass inspection the first time—CountBricks tracks every code requirement.
Residential garage furnace projects typically range from $3,200 to $7,800. The spread comes from multiple variables, all transparently displayed in your CountBricks estimate.
• BTU size and efficiency rating
• Venting length and roof vs. wall termination
• Gas line upsizing or new meter fees
• Electrical upgrades for dedicated circuits
• Insulation or vapor-barrier improvements requested during the same visit
• AI bundles material orders across projects, unlocking bulk discounts we pass directly to you
• Real-time pricing prevents mid-project change-orders caused by supplier cost spikes
• Digital task sequencing reduces crew idle time, trimming labor hours without rushing the workmanship
Adding heat to the garage can influence the load on your existing HVAC system and indoor air quality. CountBricks technicians test pressure balances, install backdraft dampers and recommend smart thermostats that network garage and home zones. You view projected energy savings right inside your CountBricks.com dashboard.
• Pre-plan tool storage: Wall-mount cabinets now, before the new furnace limits clearance options
• Consider infrared tube heat if vehicle warm-up is the main goal; it targets objects, not air
• Seal the slab perimeter—cheap caulk now prevents heat loss later
• Install CO detectors at both 18 inches and standard height for layered safety
• Photograph vent penetrations before drywall; images upload automatically to your CountBricks project file for warranty reference

Mrs. Nguyen owned a 550-square-foot attached garage in Buffalo where winter temps routinely dropped below 10°F. She contacted CountBricks through the voice chat on CountBricks.com/consultation, asking for a budget-friendly solution that would let her refinish furniture year-round.
The CountBricks estimator recommended a 45,000 BTU condensing furnace with sealed combustion, 25 feet of concentric PVC venting and R-19 batt insulation for the exposed attic bays. Total projected cost: $5,950, including permits and a smart thermostat that could be monitored from the living room.
• Material orders auto-released two days before install, timed with local supplier delivery windows
• Crew completed gas line tap, vent penetration and thermostat wiring in a single eight-hour shift
• Digital inspection checklist uploaded to the city portal directly from the CountBricks mobile app, cutting approval wait time in half
Energy monitoring shows the garage maintains 65°F on a 20°F day while adding less than $22 per month to the utility bill, exactly matching the AI forecast. Mrs. Nguyen added the garage zone to her whole-home maintenance plan inside CountBricks.com/portfolio, where she can schedule filter changes with one tap.
• Right-sizing prevents short cycling and unnecessary fuel use
• Sealed combustion eliminated worries about paint-stripper fumes igniting
• Automated documentation provides resale value; future buyers see verified install data stored on CountBricks servers
