How long does a Lennox Pulse Furnace Last?

There are many comments on HVAC forums regarding the recall of the Pulse furnace due to leaks and cracks in the heat exchanger and secondary heat exchanger. A professional on hvac-talk.com shared a statement from Lennox in 2011 that the company would no longer be producing replacement parts for the Pulse units.

” Pioneered by Lennox Industries in 1982, the G14 Pulse furnace has an AFUE–the Annual Fuel Utilization Efficiency rating–of 97.

Age of your Furnace If your furnace is pushing 25 years or more, it’s probably nearing the end of it’s effective lifespan. … You might choose to replace a 15 year old furnace, or it could last more than 30 years.

The Average Age for Gas Furnaces Other sources estimate that the average lifespan for a modern furnace is between 15 to 30 years. … Even though furnaces can last 30 years or beyond, most experts recommend that you start shopping for a new furnace when your existing unit is 15 years old.

There are some carbon monoxide safety hazards in some of the Lennox hot air heating furnaces installed before 1990. … The Lennox Pulse furnace that we are concerned with was manufactured and installed between 1982 and 1989 and poses a potential carbon monoxide threat to a home.

The date of production/manufacture or age of Lennox® HVAC equipment can be determined from the serial number located on the data plate.

Gas and air are drawn into a combustion chamber and ignited by an electronic spark. Between 60 and 70 pulses of the air/gas mixture are ignited per second producing rapid burning and a pressurized pulse. Once started, the process becomes self-perpetuating and it no longer requires the spark ignition.

Pulse Heat is Avio’s original process of utilizing resistance heat which is generated by passing an electric current through a metal heating body called a heater chip/heater tool, to instantaneously perform soldering, thermos-compression bonding, and plastic welding with heat and pressure.

How Much Does a Furnace Cost? A new furnace costs $1,500 to $6,500, depending on the model you choose. The average cost of installing a mid-efficiency furnace is $1,500 to $2,500. Mid-efficiency furnaces have an annual fuel utilization efficiency (AFUE) rating of 80% to 89%.

For example, a 700- to 1,500-square-foot home will require a BTU rating between 40,000 and 60,000, which will cost between $2,000 and $3,000. A furnace for a home ranging in size from 2,000 and 5,000 square feet will need between 125,000 and 150,000 BTUs and will cost in the neighborhood of $3,300 to $6,500.

How efficient is the average 35-40 year old furnace? 80% at best. Likely lower if it is indeed close to 40 yes old. A lot of savings to be had with a new furnace 95% with a ecm blower motor.

The Safe Answer One of the parts they’ll examine every year is the heat exchanger. The heat exchanger is inside your furnace, a place you should not go. … An older furnace is more likely to have problems with carbon monoxide escaping. If your furnace has repeated problems with CO emissions, consider replacing it.

Ideally, you don’t want to wait until your furnace dies completely to replace it. This could easily happen in the middle of winter, leaving you without any way to heat your home. Instead, keep a close eye on your furnace’s operation, both in terms of efficiency and cost.

But for less expensive repairs, you should be less resistant to replacing the furnace the older it is. So if the furnace is 20 years old, and the cost to repair the furnace is only 10% of the cost of a new furnace, you should probably replace it (because it’s more likely to break down again soon).

Model Numbers The model is identified by a “model number” which is stamped on the unit nameplate or rating plate. On residential gas and oil furnaces this identification plate is located on the inside of cabinet near the vestibule panel. On other Lennox products the plate is mounted on the outside of unit.

Standard, one-inch disposable air filters should be changed every three months.

In general, this is how often changing furnace filters needs to be done: For 1- to 2-inch filters, replace them every 1 to 3 months. For 3- to 4-inch filters, replace them every 6 to 9 months. For 5- to 6-inch filters, replace them every 9 to 12 months.

We advise buying no less than a MERV 13 if the system allows for it.

THE AVERAGE FURNACE LIFESPAN A well-maintained furnace can last at least 15 to 20 years, but completing annual maintenance and being diligent with repairs can extend its life even longer.

Though the lifespan of a home air conditioner varies based on many factors, those that are well-maintained should last 10 to 15 years. And by completing regular checkups and repairs – both big and small – many systems can last even longer.

A pulse is defined as one cycle of ignition and combustion of a gas/air mixture in a specially designed chamber. Because the pulse-combustion process is naturally aspirated and does not require a blower motor for operation, Pulse boilers reduce electrical consumption.

HVAC installation is quite expensive, probably because it has emerged to be an immensely specialized trade. Owing to controlling humidity, thermodynamics, airflow, refrigerant, electrical, and plumbing, it is now high on demand.

The average cost range for purchasing and installing a gas furnace designed to heat a 2,000-square-foot home with a 97% efficiency rating ranges from $4,000 to $8,000, with most homeowners spending around $6,000 total on a high-efficiency gas furnace replacement in a 2,000 sq. ft. home with minor modifications.

Your New Furnace Will Save on More Than Just Gas Costs If you’re thinking about buying a new furnace, there is more than just gas savings to consider. A new furnace will also save on electric costs by using a more efficient fan motor that will run less since you will heat more efficiently.
