Types of Airtemp Furnaces

Airtemp provides several types of furnaces to its customers to ensure that all of their needs are fulfilled during freezing winter nights. In order to decide which model to get yourself, this portion will help you out.  

The two categories of Airtemp furnaces are oil and gas ones. 

Oil Furnaces 

These furnaces by Airtemp have unmatched quality with clean combustion and engineered airflow. They come with high-density cabinet insulation, which makes the furnace run smoothly and quietly. The different models of oil furnaces include HighBoy, Lowboy, and Downflow. 

Gas Furnaces

The other ones are gas furnaces, which have several models as well. These also have cleaner combustion and durable finish for longevity. They are also equipped with a dependable heat exchanger. Here are the different models that Airtemp offers in the market:

VG7TC-V Models: These furnaces operate at the lowest cost and are 95% efficient. They come with two-stage heating and a variable-speed blower that is also energy-efficient and offers maximum comfort control for the members of the family.

VG7SC/L Models: This model type by Airtemp operates at a 92% efficiency rate and still offers considerable energy without boosting operating costs. They are more affordable and provide comfort for all types of homes.

Comparison Overview 

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

Lennox Fuel Oil And Airtemp Fuel Oil Furnaces

Both Lennox and Airtemp are Energy Star certified and are designed with the highest quality materials to ensure durability and longevity. They both also aim to be energy-efficient and have a similar rectangle-shaped design. 

However, Lennox has models that are up to 98.7% energy-efficient, while the highest energy efficiency level Airtemp’s furnaces have is 95%. Moreover, the former uses Precise Comfort technology for keeping consistent temperatures and SilentComfort for quiet operation. Meanwhile, the latter uses SmartLite technology and offers cleaner combustion. It also uses high-density cabinet insulation for quiet operation.

Airtemp vs. Goodman Furnace

Goodman and Airtemp both utilize multi-speed ECM blowers to ensure consistently and even heat transfer throughout the room. They are both energy-efficient as well and have an aesthetic design, which makes them look almost similar. They both also use tubular heat exchanger technology.

The difference comes in the little intricacies such as the sloped heat exchanger design on Goodman furnaces. Goodman also uses wrinkle bend technology that retains the strength of the wall and helps in even the transfer of heat. Airtemp uses engineered airflow and relies on SmartLite technology for quality assurance. 

Airtemp Furnace Troubleshooting 

You may face a number of minor or major issues during installation or after using different models of this furnace. Some of these issues may include things such as:

Thermostat Not Turning On 

This can occur due to the drainage of batteries or the debris or dust collected inside it that makes it inefficient. 

Inability Of the Thermostat to Produce Heat 

A circuit breaker or fuse that is tripped or blown can cause the thermostat to not generate heat. The filter might be terribly clogged in such a case.

Faulty Limit Switch 

An inefficient limit switch could cause the blower to operate constantly, resulting in a lack of its performance and shortening its lifespan.

 In order to fix a few of these issues, here is a troubleshooting guide:

Solid Green And Red Light on Airtemp Furnace No Amber Light

A red light on your Airtemp furnace means that a safety issue in your furnace has resulted in the shutdown of the whole furnace as it detected or recognized a fault. 

Airtemp Gas Furnace Status Green Light Flashing

If the green light on the furnace is flashing slowly, it means that the furnace is on but has received no instructions on turning on the heat. If the light is constantly flashing, you need to replace the IFC circuit board as the furnace does not receive any electrical power.

Airtemp Furnace Restarts Several Times During Heat Cycle

When a furnace restarts or shuts down itself several times, it means that it has overheated and needs to calm down and rest before starting up again. Restricted airflow is usually the cause of an overheating furnace, and it can be dangerous if it is not turned off on time. 

Airtemp Furnace Open Limit Switch Fault

The code or phrase’s meaning is that the furnace has overheated. The limit switch turns the furnace burner off and turns on the fan, especially if there is a high-temperature problem on the furnace. It can also mean that the switch is malfunctioning and needs to be repaired.

Airtemp Furnace Not Igniting

If the Airtemp furnace is not igniting, it essentially means that it needs cleaning, or it needs to be repaired. If the ignitor is dirty, it will restrict the flow of air into the furnace, which will cause It to shut down or malfunction. So you need to check the air filters for debris if this issue occurs.

Airtemp Furnace Burners Won't Stay Lit

If the 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 it’s not cleaned out.

Airtemp Furnace, No Flames

A dirty pilot flame is weak and can cause little to no flames on your furnace. It will show up as a yellow-colored indicator light, which means you need to clean the filters and repair them so that they can be used again properly and become brand new.


Airtemp offers a wide variety of products and models for all its users. The brand name is known to provide dependable and efficient solutions for home comfort. Their furnaces are quite popular and feature different models. They also come with impressive warranties as well. Good luck finding the right one for you!
