What makes a top-rated furnace?

There are many factors to consider when reading oil or gas furnace reviews and deciding which system is right for you. First, you need to know which kind of furnace you’re looking for. When comparing furnace reviews, you should consider a like gas type, efficiency, cost, warranty and more.

 

Oil vs. Natural Gas

An oil furnace generates heat using oil while gas furnaces are fueled by natural gas/propane. Oil furnaces are typically priced lower and provide more heat per BTU, but are less efficient. Gas furnaces are typically more efficient and offer lower fuel costs, but are more expensive than oil furnaces up-front.

 

Single-Stage vs. Two-Stage Heating

Single-stage heating uses a fixed gas valve and a one-speed motor to provide a single heat setting. , on the other hand, uses a two-stage gas valve and a variable-speed motor, allowing for multiple heat settings you can adjust depending on the weather.

 

Energy efficiency

Modern furnaces are becoming increasingly energy efficient, which makes them better for the environment and can reduce utility costs. Most new furnaces display an Annual Fuel Utilization Efficiency (AFUE) rating, which is a measure of fuel efficiency. Furnaces with higher AFUE ratings typically cost more, but they can reduce the overall cost of heating your home.

 

Cost

The total price of a new furnace depends on the brand, efficiency and installation costs. Additionally, gas typically costs much less than electricity. However, gas furnaces are generally more expensive to fix than electric furnaces.

 

Warranty

Most furnace manufacturers on their products. The two most common types of warranties are for the heat exchanger and for certain parts of the furnace. Warranties vary based on the price and quality of the furnace. For example, many basic furnaces include a five-year parts warranty, while top-of-the-line furnaces often have a 10-year parts warranty. Most manufacturers only honor the warranty for the individual who owned the home at the time the furnace was installed, and customers must typically register the product within a certain period of time to qualify for full warranty coverage.

 

Advanced features

Some furnaces have such as an air pressure switch, variable-speed motor, air filtration system and electronic ignition. These advanced features can reduce noise, trap dust particles and increase efficiency. Furnaces may also have smart features that improve efficiency by automatically adjusting the output to the exact amount of air needed.

 

Customer reviews

Reading customer reviews can help you choose the best furnace for your home. Find reviewers who live in a home of a similar size and in a similar climate to yours. Reviews can help you understand a furnace’s heat output, how quickly the furnace heats the home and how the furnace performs in various temperatures. Reviews may also provide information about the furnace’s reliability, common problems and typical repair costs.
