With winter season knocking on our doors, families are on the hunt for a good-quality and high-functioning furnace.

In this article, we have rounded up the best furnace models from Coleman so that you can cozy up in the warmth of your home.

So, without any further ado, let’s get started. 

Who Is Coleman?

Coleman came into being 120 years ago, and it began its journey by manufacturing and selling lanterns and camp stoves. After decades of staying in this industry, Coleman moved to manufacture HVAC products in 1958. They now have headquarters in York, Pennsylvania, and are owned by York International Corporation. 

The company is known for its dependable and reliable products that perform with great efficiency and have superior performance levels. The heating and cooling products that Coleman offers include air conditioners, heat pumps, furnaces, and packaged units. 

What Makes Coleman Furnaces Stand Out from the Competition?

Many brands in the HVAC industry have been operating for a long time, but Coleman has been functioning as a business since the 1900s. Its life-long experience gives them a competitive edge over other brands, as it has more knowledge and know-how of HVAC products. 

Along with the experience, Coleman offers exceptional warranties in terms of the limited parts as well as labor warranties. All Coleman furnaces have a lifetime heat exchanger limited warranty and 90-day labor warranty to fix any issues that may arise. This ensures confidence in the durability and performance of their products. 

Types of Furnaces By Coleman

Comparison Overview

Let’s now compare Coleman with some competitors in the market:

Coleman Furnace vs Carrier

Coleman utilizes an EcoTrak system to create a climate cycle that best suits your house. This is one of the most unique and innovative features that you will not find in Carrier furnaces. It also uses the WhisperDrive comfort system to ensure quiet operation.

Carrier uses humidity control on its furnaces to improve air quality and provide clean and refreshing air throughout the winters without making the climate sticky or irritable. It also uses insulated cabinets to ensure smooth and quiet operation of the furnace models. 

Revolve vs Coleman Furnace

Revolve furnaces are mainly produced for the manufactured housing industry, and they have several features in their furnaces, such as a multi-speed down-flow blower. Their furnaces are also up to 95% AFUE energy-efficient, which makes them quite cost-cutting and impressive. 

Coleman has a modulating burner design that comes with a variable-speed ECM fan motor. Their furnaces range from 90-98% AFUE energy efficient and are equipped with WhisperDive and EcoTrek technologies to make them stand out more and boost their performance.

Coleman Furnace vs Goodman

Goodman uses several unique, innovative technologies, such as a tubular heat exchanger with wrinkle bend technology, which is designed to maintain durability and promote heat transfer. The top features also include a multi-speed PSC blower and ECM blower to enhance airflow and provide heat consistently.

Coleman uses other technologies to make sure that users have maximized comfort and value for money. The cabinets are insulated, and the furnaces are equipped with EcoTrek and WhisperDive, as opposed to the wrinkle bend technologies used by Goodman.

Coleman Furnace Troubleshooting 

Users may face some minor issues with the furnace, whether it’s regarding installation or its performance. This section guides you on how you can fix those issues. Here are some of the most common furnace problems that may arise:

Furnace Not Heating 

The main issue that arises is that the furnace is not heating up properly. In order to fix this, you must first check your furnace’s igniter to see if it’s cracked and faulty.

Noisy Furnace

Check the blower wheel to see if its screws are properly tightened or not. The chances are the wheel may be damaged, or the screws are loose.

Coleman Furnace Blower Motor Problems

There may be several issues that you might face with the blower motor. If it is burned out, you need to replace it altogether. If it hums, then you should check if the fan of the blower motor is spinning freely. If the capacitor of the Coleman is defective, it may not run or be noisy. 

Coleman Furnace Error Codes

There are three-colored lights that flash, of which red indicates something wrong with the furnace’s operations. Green indicates normality, red has different meanings, depending on the number of times it flashes, and amber means normal operation with a request for heat.

One blinking red light means that the gas valve needs to be checked, while two and three flashes mean that the pressure switch is immobile from the open position. Four flashes mean that the limit switch is faulty, five means the rollout switch needs to be checked, and six means the pressure switch cycle has been locked out. 

Coleman Furnace Error Code 4

Four red flashes mean that there is an error with the limit switch, and it has been stuck while opened. You need to check whether the filter is dirty or not or if the duct has been improperly sized. There can also be an issue with the blower motor. 

Combustion Air Switch Failed to Close on Coleman Furnace

Check if all the tubes are cleaned out and running. If it still doesn’t work, you might need to replace it. 

Coleman Furnace Pilot Light Keeps Going Out

One of the most common reasons for this is that the thermocouple is set a longer distance from the pilot light. It should be adjusted in a way such that the pilot light gives a flame of at least two inches long.

Coleman Furnace Limit Switch Stuck Open

This could be because the filter is dirty or because the duct is sized improperly. 

How to Check Coleman Furnace Lighter

If the furnace burner keeps malfunctioning or shutting on and off, you might need to check its air filters. Overheating and other malfunctioning issues can occur if the furnace burners aren’t cleaned out properly. The air can be restricted, and the furnace won’t stay lit if not cleaned out.

Coleman Furnace No Fault Light When On Lowest Setting

The pilot light can be one of the main reasons why the furnace doesn’t ignite. If the igniter or sensor is dirty, it needs to be cleaned in order for the pilot light to work.

First, you must wipe the condenser coils with the help of its special cleaner. You can even use soap and water for the job. Use a hose or shower to wash it. Use a fin comb to make sure there are no bent condenser fins. Put the top grill back on with the heat pump cover back into place.
