Furnaces (Natural Gas & LP)

Choose the right gas furnace for your home or light commercial space with options in 80% metal-vented and 92%+ PVC-vented designs. Our lineup is built for ducted forced air systems, offering reliable heat, quiet operation, and broad install flexibility. With everyday value pricing from about $940 to $1703 and heavy in-stock inventory, you’ll find the performance you need without overspending-professional installation required.

Size your system by output: we carry 40,000 to 100,000 BTU models to match your load and climate. Pick the airflow orientation that fits your layout-Upflow/Horizontal, Downflow/Horizontal, or Multi-Position-and match cabinet width to your existing plenum: 14-14.5", 17.5", 21", or 24.5". Subcategories make selection easy: 80% Metal Vented for traditional B-vent installs, or 92%+ PVC Vented for condensing efficiency with PVC vent and condensate management.

Key specs include AFUE 80, 95, and 96 options, BTU outputs from 40k-100k, and multiple cabinet sizes for tight closets or full basements. These gas furnaces do not use refrigerant; when pairing with cooling, select a compatible coil and filter-drier per your AC or heat pump specs. SEER2 applies to cooling equipment only, but proper blower sizing ensures your furnace pairs well with high-efficiency AC systems.

Designed for homeowners, DIY-capable buyers (with licensed install), contractors, and property managers, these furnaces deliver dependable heat and straightforward serviceability. Many models ship ready for natural gas and are field-convertible to LP with an approved kit-always verify local code, venting type, and clearance requirements.

Frequently Asked Questions

  • How do I choose the right BTU size furnace for my home?

    Match output to a Manual J load calculation. Typical homes fall between 40,000 and 100,000 BTU depending on size, insulation, ductwork, and climate.

  • What is the difference between 80% metal vented and 92%+ PVC vented furnaces?

    80% units vent via metal (B-vent) and exhaust warmer flue gases; 92%+ condensing models use PVC venting, extract more heat, and require a condensate drain.

  • Which airflow orientation do I need for my install?

    Choose Upflow/Horizontal, Downflow/Horizontal, or Multi-Position to match your duct system and space constraints. Follow model clearances and return-air guidelines.

  • Are these furnaces convertible between natural gas and LP?

    Most ship for natural gas and are field-convertible to LP with a manufacturer-approved kit and proper setup. Check the model specs and follow code.

  • What cabinet width will fit my existing duct/plenum?

    Measure the supply/return openings. Common widths are 14-14.5", 17.5", 21", and 24.5" to align with standard plenums and coils.

  • What are the pros and cons of AFUE 80 vs AFUE 95/96?

    80% offers lower upfront cost and simpler venting; 95/96% lowers gas usage and utility bills but needs PVC venting and condensate handling.

  • Do these furnaces require professional installation and permitting?

    Yes. A licensed installer is typically required for code compliance, safety, warranty validity, and proper gas, venting, and electrical setup.

  • Can I use these furnaces in light commercial spaces?

    Yes, when properly sized and installed to local codes, with suitable gas supply, ventilation, and clearances for the application.

  • Can I pair these furnaces with an existing AC or heat pump?

    Yes. Match the indoor coil and blower CFM to your outdoor unit. SEER2 ratings apply to the cooling side, not the furnace.

  • What maintenance is recommended after installation?

    Replace filters regularly, schedule annual professional service, and for 92%+ models, keep the condensate trap and drain clean.
