Why it Stands Out to Us

It stands out to us with its amazing energy efficiency of 96%. It ensures that there are minimum fuel losses even when the furnace runs constantly. This way, there is greater heat generation at lesser fuel consumption. 

Moreover, it has stainless steel heat exchangers that do not rust or damage easily. The lifetime warranty makes these heat exchangers even more reliable for users. 

In addition to the live weather updates, it provides a five-day weather forecast as well. This lets you stay prepared for the upcoming weather conditions. 

The remote control lets the users operate the furnace even from work. So, there’s a warm room awaiting them when they get home. Hence, this one from the Armstrong pro series is a definite winner. 

Bottom Line

Considering all its features, the A962V is a remarkable furnace. It helps in keeping your place comfortable all the time without you having to break your bank. The running cost is quite low as the fuel-burning mechanism is super-efficient.

Unit Warranty: Limited Lifetime Warranty on the stainless steel heat exchanger

We may earn commission from purchases made from our links, at no additional cost to you

Why it Stands Out to Us

The L83UF is the runner-up on our list due to the insulated cabinet that it comes with. The insulation prevents loss of any warmth, making sure that the rooms stay warm even after the furnace is off. It also enables the furnace to provide more warmth as there are no background heat losses.

Furthermore, the furnace has a well-connected duct system in it. There are clean-cut pumps along with the ducts that regulate air better. There is lesser energy required for maintaining the required airflow with this duct system.

Along with all this, there is a solid-state ignition feature as well, which keeps things clean and active.

Bottom Line

All in all, this is an amazing furnace by Armstrong, which minimizes heat losses. The energy efficiency rating is also quite high at 86%, so there is less worrying about fuel costs. So, go for this furnace if you want something which does not give up on you easily.

Why it Stands Out to Us

We found this to be highly affordable due to the features-to-price ratio. This Armstrong furnace comes loaded with features that customers love. The Comfort Sync in it keeps a close check on the internal functioning of the furnace. It informs you as soon as it detects any potential damages, ensuring a smooth supply of warmth. 

Moreover, the furnace has a very low NOx emission rate, making it safe for you and your family. 

In addition to this, the EHX technology makes this furnace much more reliable. It keeps the frame functioning for a longer time period, so your investment will go to good use. 

Bottom Line

Summing up, this is an amazing furnace that keeps the fuel costs to a minimum. The furnace goes into an ultra-energy saving mode when you leave your place. Thus, it keeps your place warm all the while and goes light on your pocket too.

Why it Stands Out to Us

Armstrong A97MV is another one of our favorite furnaces that has impressive performance. It has a very high-efficiency rating at 97% AFUE. This ensures that there is a negligible waste of fuel. 

Moreover, it has a heat modulation option that lets users choose from multiple heat settings. This way, you can control the temperature at your place more actively. The furnace has become Energy Star most efficient 2020, increasing its reliability. 

Also, it has a limited lifetime warranty on the heat exchanger, which gets most of the work done.

Unit Warranty: Limited Lifetime Warranty on the stainless steel heat exchanger

Why it Stands Out to Us

This furnace has caught our eye with its PSC burner motor and the overall construction quality. The PSC motor constantly runs on a set level. This minimizes fluctuations in fuel consumption and keeps a constant flow of warm air. 

Furthermore, the furnace has active noise reduction as it burns small BTU units per hour. The simplicity of working keeps a calm aura at your home, making it more relaxing. 

The blower motor is another great addition as it helps you set the speed of heating. So, this is a worthy furnace with its high energy saving capacity and heat generation.

Bottom Line

Keeping all this in view, we recommend this Armstrong furnace to all those looking for a reliable heating option. This can be a great choice, even if you are making a new house.

Energy Efficiency (AFUE): 83%

Parts Warranty: 10 Years Limited Warranty

Unit Warranty: Limited Lifetime Warranty on the stainless steel heat exchanger

We may earn commission from purchases made from our links, at no additional cost to you

Why it Stands Out to Us

It has earned our approval with its superior construction, which keeps external damage to a minimum. The silver-grey body can last many decades with the least weather damage. Its stainless steel heat exchangers and the durable air pumps ensure a hassle-free usage. 

Moreover, it has a standard efficiency value of 86%, which helps you in saving more on fuel prices. The PSC motor also restricts the usage of fuel to save it further. 

Also, the ducts are well connected, which prevents any loss of warm air. The cabinet has insulation, which helps the ducts save even more heat.

Bottom Line

The bottom line on this is that it is definitely worth a shot. The oil furnace works amazingly well to keep the emissions to the least possible level. So, get this one if you want to update the heating system at your place.
