How We Reviewed
Where our data comes from
We gathered information from various trusted sources, including furnace product listings, manufacturer specifications, and customer reviews. This ensured many reliable data for our furnace comparison.
How we built this shortlist
To create this shortlist, we reviewed over 20 different furnace models. We focused on heating capacity, efficiency ratings, and features like multi-speed motors. This helped us find the best options available.
What we ruled out and why
We excluded models that had poor customer ratings or lacked essential features like warranties. If a furnace did not meet minimum efficiency standards, it was also removed from consideration.
What we did not do
No hands-on testing or lab measurements were performed. We did not invent scores or ratings; all information is based on available data from reputable sources.
How often this page is updated
This page is updated quarterly to reflect changes in product availability, new models, and updated customer feedback. This ensures you have the most current information.
What to look for
Heating Capacity
Look for the BTU (British Thermal Unit) rating of a furnace, as this indicates its heating capacity. A higher BTU means more heat output for larger spaces. For average homes, consider models between 60,000 to 120,000 BTUs.
Efficiency Ratings
Furnaces have efficiency ratings measured in AFUE (Annual Fuel Utilization Efficiency). Higher AFUE percentages indicate better efficiency. Aim for a furnace with at least 80% AFUE to save on energy bills.
Installation Type
Furnaces come in different installation types, such as upflow or downflow. Make sure to choose a model that fits your home’s existing ductwork. If you’re unsure, consult a professional installer.
Energy Source
Furnaces can run on natural gas, propane, or electricity. Your choice depends on availability and cost in your area. Gas furnaces typically provide lower heating costs compared to electric models.
Warranty Options
A solid warranty can provide confidence. Look for furnaces that offer at least a 10-year warranty on parts. This indicates the manufacturer’s confidence in the product’s durability.
How to Choose Furnaces
Understand BTU Requirements
Determine the heating needs of your home by calculating the BTU requirements. This depends on factors like house size and insulation. Generally, you’ll need about 30 BTUs per square foot.
Check AFUE Ratings
Look for a furnace with a high AFUE rating to maximize efficiency. A furnace with 90% AFUE or higher is considered very efficient. This can significantly reduce your energy bill over time.
Assess Installation Space
Measure the space where the furnace will be installed. Ensure that the model you choose fits in the designated area. This includes checking for necessary clearances and duct connections.
Evaluate Fuel Type
Consider what fuel source is most accessible for you. If natural gas is available, a gas furnace can be a cost-effective choice. Propane furnaces may be better for rural areas without natural gas.
Review Warranty Options
Look for furnaces that offer a solid warranty upon registration. A warranty of at least 10 years on parts is ideal. This will protect you from unexpected repair costs.
Frequently asked questions
What should I compare in a furnace?
When comparing furnaces, focus on heating capacity (BTU), efficiency ratings (AFUE), installation type, and warranty options. These factors will help you choose the right model.
How do I find the right size furnace?
Calculate your home’s BTU needs based on its size. A general rule is 30 BTUs per square foot. This will help you determine the appropriate furnace size.
