SLP99V Variable-Capacity Gas Furnace
5/5A Remarkably Quiet Heating Experience
2 January, 2023
I recently decided to replace my aging furnace, and I was promised that the new one would be remarkably quiet. Initially, I had my doubts because my old furnace didn’t seem all that noisy to me. However, I was in for a surprise. On the first frosty night after the installation, I quickly realized just how wrong I had been about my old furnace’s noise level.
It turns out that I had grown so accustomed to the constant hum of my previous furnace that I hadn’t noticed how disruptive it could be. With the new furnace in place, I enjoyed an uninterrupted night’s sleep, and it dawned on me that I hadn’t heard a single noise from the heating system. The tranquility it brought to my home was truly unexpected and welcome.
Beyond its silent operation, this furnace has significantly improved the comfort of my home. It effortlessly maintains a consistent and cozy temperature, even during the harshest weather conditions.
I also need to mention the S30 thermostat that came with the furnace. It’s not only incredibly easy to use but also adds a modern touch to my home’s interior. The weather screen savers it offers are a delightful bonus, providing captivating visuals that make checking the temperature a more visually appealing experience.
I want to extend my heartfelt thanks to Van Haaften Plumbing & Heating for their outstanding service and for introducing me to this exceptional furnace. It has not only exceeded my expectations in terms of its silence but has also made my home a more peaceful and comfortable place to live.
