How We Reviewed

Where our data comes from

We gathered information from respected sources in HVAC technology and consumer reviews. Our data includes manufacturer specifications and user feedback from reliable websites. This helped us confirm product details and understand user experiences.

How we built this shortlist

We examined over 20 furnace models to find the best cheap furnace options. Our focus was on efficiency ratings, BTU output, and installation types. We narrowed down our list based on these key features and consumer feedback.

What we ruled out and why

We excluded models that had poor customer reviews or low efficiency ratings. Any furnace that did not meet a minimum 80% AFUE rating was also removed. This ensures only reliable and efficient options are included.

What we did not do

We did not conduct hands-on testing or lab measurements for any of these furnaces. All findings are based on research from various sources, without any invented scores or subjective evaluations.

How often this page is updated

This page is reviewed and updated every six months. We check for new product releases and changes in specifications. Keeping the information current is important for your buying decisions.

How to Choose Furnaces

Understand Efficiency Ratings

Look for furnaces with an AFUE (Annual Fuel Utilization Efficiency) rating of at least 80%. This indicates how efficiently the furnace converts fuel into heat. Higher ratings mean better efficiency and lower energy costs over time.

Check BTU Output

The BTU (British Thermal Unit) output tells you how much heat the furnace can produce. Choose a furnace that matches the size of your home. For example, a home that needs 60,000 BTUs should not use a furnace rated for 80,000 BTUs.

Consider Installation Type

Different furnaces are designed for upflow, downflow, or horizontal installation. Ensure you select a model that fits your home’s layout. Review the specifications to confirm that it can be installed correctly.

Look at Warranty Options

Furnaces often come with warranties that cover parts and labor. A good warranty can provide confidence. Look for models with at least a 10-year limited parts warranty for better protection.

Evaluate Size and Space Requirements

Measure the space where the furnace will be installed. Ensure that the unit fits comfortably in that space. A unit that’s too large or too small can lead to inefficiencies and increased energy costs.

What to look for

Fuel Type

Furnaces can use natural gas, propane, or electricity as fuel. Natural gas is often the most economical choice. Propane can be a great option in rural areas. Electric furnaces can be less expensive but may have higher operating costs.

Noise Levels

Consider the noise produced by the furnace during operation. Some models have quieter operations due to advanced motors. Look for specifications that mention noise levels in decibels (dB) for better understanding.

Maintenance Needs

Regular maintenance is important for furnace efficiency. Some units require more frequent filter changes or inspections. Choose a model that fits your willingness to perform or pay for regular upkeep.

Heat Exchanger Material

The heat exchanger is a critical part of a furnace. Aluminized steel is common and durable. Stainless steel options may be more resistant to corrosion but can be pricier. Each material has its benefits and drawbacks.

Control Features

Modern furnaces may come with smart controls that allow for remote operation. Look for models that offer programmable thermostats or smart home integration. These features can enhance comfort and reduce energy use.

Frequently asked questions
