Benefits of Modulating to Two-stage to Single-stage | Armstrong Gas Furnace Reviews

Of course, the modulating gas furnace is all the rage for high-efficiency gas furnaces now. However, with two-stage gas furnaces, you can achieve similar efficiency levels for AFUE between the two types of gas furnaces.

The key difference, despite similar efficiency levels, is the temperature swing or comfort level between a two-stage and modulating gas furnace. This can be a factor for you when purchasing a new gas furnace especially when it comes to pricing the new gas furnace system. See the chart below for more details.

Warranties | Armstrong Gas Furnace Reviews

Armstrong has a lifetime limited warranty on their heat exchangers. This is good for you the consumer although always read the fine print with any warranty. Most people do not know that many HVAC warranties only cover the part and not labor. If the gas furnace is out of warranty then you pay for the part and the labor. Except for the heat exchanger on any Armstrong gas furnace.

That’s a plus for you because heat exchangers stand up to a lot of heat and corrosive moisture. Always register the warranty soon after installation. This is a requirement for many manufacturers. Additionally, find out what the exclusion clauses are such as owner transfer.

Comfort Sync™ | Armstrong Gas Furnace Reviews

Armstrong has a thermostat control that has many features including an app for Android or Apple smartphones. You can also use a PC to access the thermostat control. That allows you the ability to have remote access for monitoring and control. Leave for vacation and forget to set back the thermostat; no problem, just open the app on your smartphone and take care of it. Additionally, other features include:

  •  Live weather reports on the thermostat interface
  • Easy programming and scheduling
  • Alerts for problems and reminders for maintenance
  • Touchscreen interface
  • Zoning control

Zoning control does require modification to your ductwork. Motorized dampers must be installed to make it work. Additionally, you need to have mid-range to premium range equipment to make it work. Additional sensors are mounted in the zones and communicate with the thermostat. Each zone can have a different setpoint so everyone can be comfortable at their own temperature. See the video below for more details.

Is Armstrong a Good Furnace Brand?

Yes, Armstrong builds a good product with their furnaces. Additionally, they have good quality control for their equipment before it leaves the factory. When purchasing a gas furnace or any HVAC system the thing to remember is the quality of the contractor over the brand. A badly installed gas furnace, no matter the brand, will give you frustration and not be efficient as a gas furnace that is correctly installed. The installation and all the details of the installation are up to the contractor. Therefore, you want a quality contractor doing the work.

How long should an Armstrong gas furnace last?

According to Money Magazine, the average air conditioner and furnace system will last 13 years. This is in line with my opinion. If the gas furnace is properly installed and maintained you can get up to 20 years out of a gas furnace no matter the brand. Other than some basic repairs for common failures, the most common major failure for a gas furnace is the heat exchanger. This is why we stress the importance of a good warranty, especially for the heat exchanger.
