Consistently Perfect

Consistently Perfect

Precise Comfort® technology allows the furnace to keep the temperature held exactly where you want it. Heat is even throughout your home, with no cold spots. If it sounds perfect, it’s because it is.

Smarter Together

With the help of the iComfort® S30 ultra smart thermostat, the SLP99V gas furnace unlocks a world of connectivity. It stays finely tuned to your home by using sensors to react, diagnose, and troubleshoot—all while remaining in constant contact with your dealer to ensure proactive responses. Geofencing technology ensures your air turns on and off as you come and go. And the system even responds to the outdoor environment to adjust operation to account for factors like pollen and outdoor air quality.

Beyond Quiet

Even with all of its impressive power, this furnace is the quietest you can buy and has been engineered to run at variable speed to drastically minimize the sound of air kicking on or off inside the home.

Changed furnace and AC proaktiv After 25 years

November 20, 2022

We live in Ontario Canada, bought the house in2016. Until last week we still had the original furnace and AC,which were 25years old. Since this is our for ever house we wanted something good. Lennox is one often top units around and went onto Lennox web page and they connected us with Guaranteed Comfort Windsor. Matt came out to quote the job and he did three different options, which I compared with 10 other quotes. Decided 2weeks later and did the purchase furnace SLP99 and 16axc merit two stage AC. Six days later the installation team Matt and Stephan were at my house to install. Great guys, very knowledgeable, followed the installation guide ! Very important to me. We Hartley know they were there and they were clean. The total installation was a once of art!, I thought the guys installed their own equipment. They even went the extra way and mad a metal pocket for the manual’s. After everything was done started the system had small issues with the S30 but a couple of phone calls cleared it all away. Did the debugging found one wire was wrong for humidifier, swapped it and all good. System was running we did not hear anything quite and the tem in the house started getting even all the way around. We use to have it set to 74 now we are at 71 and have the same comfort level! The furnace pulled 1.5 amp vs 9.6 on the old one and in humidifying mode only 0.7 amp. I work out in the morning and my wife could hear my iPad from the second story of our house. Before it was lout and noisy specifically at start up. We are happy we went with Guaranteed Comfort and Lennox! We can’t wait to see the performance of the AC in the spring .

High Satisfaction Rate

April 16, 2022

Beware of people with ulterior motives who are bashing this unit. A lot of dealers can’t even get their hands on Lennox equipment (Lennox is selective in who they work with) and some will bash Lennox simply because it’s something they can’t get but that their competitor has. Make no mistake about it, Lennox is the best in the business. And I’ve been in front of hundreds of the SLP99Vs and it’s VERY rare for someone to be dissatisfied with this unit. Most feel like it was a very rewarding purchase and love the benefits it provides.
