Overview of the SLP98V
The Lennox SLP98V is a gas variable-capacity furnace currently manufactured by the company. It can achieve an efficiency rating of up to 98.2 percent, which Lennox claims can save the customer more than $800 each year compared to basic units. The SLP98V comes equipped with a self-calibrating variable speed inducer and a stainless steel secondary heat exchanger. It has dual-fuel capability, meaning it can be paired with a heat pump to provide increased comfort and efficiency. The variable-speed motor offers quiet operation. This furnace has been recognized as one of the Most Efficient of Energy Star furnaces for 2012, which means it is both extremely efficient and prevents greenhouse gas emissions.

"Dave Lennox Signature Collection Gas Furnace"
This furnace gives a nice even heat. It is so quiet that you don't realize it is on. I'm very happy that I purchased this furnace.

"Howling Noise at All Fan Speeds"
I have two new SLP98V just installed. They both make a quiet howling (harmonic) noise which is much more annoying than the blowing noise that my old Amana made. The Amana was replaced to get the improved air purification system and computerized thermostats with smartphone link. The other unit was replacing an older broken furnace. Service guys are very nice and are working with Lennox to "fix the problem". One entire unit was replaced already, quieter but still howling. So far, no real improvement. At high seed, the fan is as loud or louder than my previous furnace (which wasn't that loud). There is also a pipe tapping noise when the gas valve opens and closes. If they can't "fix" it, I will reinstall the Amana, add an aftermarket MERV 16 air filter and give up the cool thermostats at considerable financial loss. Lennox does some pretty aggressive advertising about how quiet their furnaces are but you just never know. Good luck with your purchase.

Heater continues to fail. Stopped working again after service call of less than a month. Heater has not worked for more than 6 months without a malfunction.

I have installed several SLP98Vs, not a single problem with the furnace. Our customer love it, some of them have 2 in their home. Lennox engineering is great and they stand behind their product. They will even have a field consultant to come and check the furnace or A/C, if there is a problem the tech cannot find. The installation is the most critical point of a furnace working properly. Most of the installation, we see the furnace is over sized and the duct is too small. Every sale should be provided with a load calculation for the home. The duct system, and the airflow should be checked to determine how well the new system should perform.

This furnace does exactly what it says it will do. My heating bills dropped like a rock. I never hear it run and my home stays comfortable with even temperatures all winter. One note to Ted who had problems with pressure switches. Check to make sure the furnace is vented correctly. The SLP98V is a direct vent furnace which means the vent pipe for both the exhaust and the intake should be the same length. Other Lennox 90+% furnace are indirect vent furnaces, meaning the intake vent does not have to run the full length. An imbalance can cause pressure switch trips, which easily could be diagnosed by a technician as a bad switch. I am a bit confused though, because you should have had a labor warranty to go with your 10 year parts warranty. Should that not have eliminated your costs? Who installed your furnace? Was installed by a Lennox Premier Dealer? Full disclosure - I work for a Lennox Premier Dealer. I purchased and had this furnace installed in my home so my review is a personal review. That said, I have some insight to some of the issues we encountered. Mine was the first one we installed in this market.

"Lennox is Awesome!"
Most gripes seen more centered around bad service issues and installation. SLP98V I put 1 in my home, silent operation. 100's installed, yes bad icomforts + 1 out of 25 defective air switches. Lennox resolved, no problems since. Unfortunate that dealers don't bother to train their staff how to troubleshoot and install properly that is the only major problem I see. Excellent engineering by Lennox on these new units.

"1.5 year old, Pressure switches failed, cost $400, Lennox refused to help"
1.5 yr old, pressure switches failed, called Lennox, no backing of the failed product whatsoever, read the fine print, fixing cost over $350+half day off work - very very disappointed.

"My lennox SLP98V furnace"
I've owned my furnace for about six months. It's reliable, quiet, and works well for the most part. It gets pretty cold where I live so having a reliable furnace is important to myself and my other roommates. It's quite efficient and my heating bill last month was as low as it's ever been. It was reduces approximately 10% compared to our older furnace that was replaced last winter. Now that summer is here, our cooling costs have also gone down by the same 10%. It had to undergo one repair because it was not installed correctly, but this was taken care of by the people who installed it within the same week. It sometimes runs a little loudly as well, especially at night when the house is quiet. I would buy this brand again because of its great energy efficiency and overall quality, despite the few issues we had with it.

"Best purchase I have ever made"
I was an installer for lennox for a couple of years and I have now totally changed careers but that is besides the point. My slp98v furnace is the best purchase I have ever made, it runs great and never know its even running. I am a strong believer of lennox products and lennox only because to me they are built the best and lennox I feel is always one step beyond everyone else. now a furnace is much like a new vehicle on the market, if you buy something that is brand new and they havent yet been able to work out any of the kinks in the model you may have problems but that is a risk you must take to get quality and reliability! Best part is if something breaks on a new model and it is to do with a fault, it will be covered by warranty. so dont complain and relax you people.
