The Goodman 80,000 BTU 80% Efficiency Multi-Speed furnace is our best overall pick. Its cabinet is only 17.5 inches wide, making it suitable for various spaces. This model replaces older Goodman models and offers reliable heating at an affordable cost. Compared to other models, it provides decent efficiency without the higher price tag found in premium models. While it may not have the highest AFUE rating, it still performs well for most residential needs. On the downside, it’s not suitable for downflow installations, which limits its use in some homes.
When comparing this model to others, the Goodman 92% AFUE model offers higher efficiency but at a cost. This model is a better fit for those focused on energy savings. However, for buyers who prioritize initial costs, the 80% efficiency model delivers greater value. This choice makes it a favored option for budget-conscious homeowners.
The main limitation is its efficiency rating. While 80% efficiency is decent, it may not help you save as much on energy bills compared to higher-rated models. Buyers should weigh the benefits of upfront cost against long-term energy savings.
Pros
- 80,000 BTU heating capacity
- Compact cabinet size of 17.5 inches
- Multi-speed ECM motor for efficient airflow
- Replaces older Goodman models easily
Cons
- Not suitable for downflow installation
- Efficiency may lead to higher energy bills over time
Best for: Budget-conscious homeowners. Not ideal for: Those needing higher efficiency for larger spaces.
A solid choice for those looking for reliable heating without breaking the bank.
2. Best for Small Spaces
Goodman 92% AFUE Single Stage Upflow/Horizontal multi-speed 80k BTU Low NOx Natural Gas furnace (17.5 wide) (GR9S920803BN)
- This comes with a 10-year parts limited warranty provided it is installed by a qualified installer and registered online with 60 days of installation
The Goodman 92% AFUE Single Stage furnace is our best pick for small spaces. It has the same compact 17.5-inch width as the 80% model. This makes it a great choice for tight areas where space is limited. Its efficiency rating of 92% ensures that you are getting good energy savings. Compared to other models, it offers a good balance between size and efficiency. The downside is that it may cost more than the basic model, making it less appealing to budget-focused buyers.
When put against the Goodman 80% model, the main difference lies in efficiency. The 92% model is designed to save you more on energy bills. However, those savings come at a higher upfront cost. If you are only heating a small space, the savings may take time to realize.
One limitation to consider is the requirement for professional installation to ensure the warranty remains valid. If you prefer to install it yourself, this model may not be the best fit.
Pros
- 92% AFUE for improved energy efficiency
- Compact size suitable for small spaces
- 10-year parts limited warranty available
- Multi-speed motor for effective heating
Cons
- Higher upfront cost compared to the 80% model

How to Choose Furnaces
Understanding BTU Ratings
BTU stands for British Thermal Unit. It measures the heating power of a furnace. A higher BTU rating means more heat output. For a standard home, aim for 30-60 BTUs per square foot. This ensures adequate heating without wasting energy.
Importance of AFUE Ratings
AFUE stands for Annual Fuel Utilization Efficiency. It measures how efficiently a furnace converts fuel into heat over a year. Look for models above 90% AFUE for better energy savings. Lower ratings mean higher energy costs.
Choosing Between Single-Stage and Two-Stage
Single-stage furnaces turn on at full capacity only. They are simpler and cheaper but less energy-efficient. Two-stage models adjust heating output, improving comfort and efficiency. Consider your climate and heating needs when choosing.
Space Considerations for Installation
Furnaces come in different sizes. Ensure your chosen model fits your installation space. Measure the area beforehand. Also, consider venting requirements and if the furnace can be installed in a horizontal or vertical position.
Warranty and Maintenance
Check the warranty offered by the manufacturer. A longer warranty can provide confidence. Regular maintenance is also important to ensure optimal performance and longevity. Follow the manufacturer’s maintenance guidelines.

Frequently asked questions
What are the best furnace deals for energy efficiency?
The best furnace deals for energy efficiency include models with high AFUE ratings. Look for options above 90% AFUE for optimal savings.
Are smaller furnaces less efficient?
Not necessarily. Smaller furnaces can be efficient if they match the heating needs of your space. Proper sizing is key.
What’s the difference between single-stage and multi-stage furnaces?
Single-stage furnaces run at full capacity, while multi-stage ones adjust their heating output. Multi-stage models offer better comfort and efficiency.
How do I know if a furnace is the right size for my home?
To determine the right size, measure your home’s square footage. A rule of thumb is about 30-60 BTUs per square foot.
How often should I maintain my furnace?
It’s best to check and maintain your furnace at least once a year. Regular maintenance keeps it running efficiently and safely.
What to look for
Energy Efficiency Ratings
Energy efficiency is important for saving on heating costs. Look for AFUE ratings when selecting a furnace. Models with AFUE above 90% are typically the most efficient. They convert nearly all fuel into heat, minimizing waste. This is especially important during cold months.
Installation Requirements
Different furnaces have specific installation needs. Some are designed for upflow or horizontal installation only. Check your space and choose a model that fits. Ensure you follow all local building codes and safety standards during installation.
Fuel Type Options
Furnaces can run on natural gas, propane, or electricity. Choose based on availability and cost in your area. Natural gas models are common and often more economical. Electric models may be easier to install but can be more expensive to run.
Size and Space Considerations
The size of your furnace affects heating efficiency. A furnace that’s too large can waste energy, while one that’s too small won’t heat effectively. Measure your home and select a model that fits your heating requirements.
Warranty and Support
When buying a furnace, check the warranty terms. A longer warranty often indicates the manufacturer’s confidence in their product. Look for brands that provide good customer support to assist with any issues.
