View full detailsHVAC Store provides superior furnace solutions engineered for dependable, real-world performance. Whether you are selecting a system for a new build or upgrading a long-serving unit, our collection allows you to compare premium upflow, downflow, and multi-positional models side-by-side. Every residential furnace in our lineup is backed by transparent efficiency data, exceptional build quality, and a team dedicated to helping you find the tailored solution for your specific heating needs.
Our furnace collection features innovative gas designs that maximize fuel conversion, with AFUE ratings reaching the mid-90s for significant long-term energy savings. Options range from reliable single-stage models to cutting-edge two-stage and variable-speed systems that fine-tune heat output for consistent comfort and reduced utility costs. For most residential applications, a natural gas furnace remains the leading choice, offering a service life of 15 to 20 years when supported by professional maintenance. In regions without natural gas infrastructure, our propane and electric alternatives provide robust heating for homes of any size.
We offer residential furnaces sized for everything from compact utility closets to expansive multi-story homes, with BTU capacities ranging from 30,000 to 140,000 BTUs . These top-notch units are listed with precise cabinet widths to ensure a seamless match with your existing ductwork. Selecting a high-AFUE model supports a more sustainable home environment, especially when integrated with a properly matched air conditioner or heat pump for year-round climate control.
Match Capacity to Your Floor Plan: System sizing is critical; our range of 30,000 to 140,000 BTU units ensures you can select a furnace that maintains stable temperatures without inefficient short-cycling .
Compare AFUE Ratings: A furnace's AFUE (Annual Fuel Utilization Efficiency) directly impacts your monthly investment; choosing a high-efficiency model provides peace of mind through lower operating costs.
Verify Fuel Availability: Select between natural gas, propane, or electric configurations based on local utility availability and your existing mechanical setup.
Prioritize Comfort Technology: Two-stage and modulating furnaces with variable-speed blowers deliver quieter operation and more even heat distribution compared to standard single-stage units.
Factor in Installation Requirements: When investing in a new system, ensure you coordinate with a licensed professional to account for ductwork adjustments and flue requirements to maintain your comprehensive warranty coverage.
Focus on your fuel type, the required BTU capacity for your square footage, and the airflow configuration—such as upflow or downflow. Matching these technical specs to your existing ductwork ensures an efficient installation and exceptional long-term performance.
The AFUE rating measures how effectively a furnace converts fuel into usable heat; for example, a 96% AFUE rating means only 4% of the energy is lost through exhaust. Upgrading to a high-efficiency furnace is a sustainable choice that significantly reduces fuel waste and monthly utility bills.
Natural gas is often the most cost-effective fuel source for primary heating. However, for homes without gas lines, our propane and electric furnaces offer reliable and premium heating performance for any application.
With regular professional maintenance, a quality furnace typically provides trusted performance for 15 to 20 years. Routine filter changes and annual inspections are essential to preserving the system’s efficiency and ensuring your comprehensive warranty coverage remains active.
While single-stage units run at 100% capacity whenever they are active, cutting-edge variable-speed systems adjust their output to meet the exact heating demand of the home. This results in quieter operation, superior humidity control, and the highest potential for energy savings
