Dave Lennox Signature Series Furnace SLP99V

An AFUE rating of 99% means that nearly all the energy consumed by the furnace is converted directly into heat for your home. Compared to older, standard-efficiency models, this significantly reduces wasted fuel and can lead to noticeable savings on your monthly heating costs.

Unlike single-stage furnaces that only run at full capacity, the variable speed motor adjusts its output based on your home's specific heating needs. This allows for longer, gentler heating cycles that eliminate cold spots and prevent the sudden temperature swings common with traditional systems.

Yes, the S40 Smart Thermostat is fully compatible with both Google Assistant and Amazon Alexa. This allows you to adjust your home's temperature using voice commands or integrate it into your existing smart home routines.

To maintain the full 12-year warranty coverage, you must schedule professional annual maintenance for the furnace. This ensures the system remains in peak operating condition and helps prevent potential issues before they arise.

The Healthy Climate 5-inch MERV 11 filter is much thicker and more effective than standard one-inch filters. It is designed to capture a higher percentage of dust, pollen, and other common household allergens, helping to keep your indoor air cleaner.

The SLP99V is engineered for extremely quiet performance. Because it uses a modulating burner and a variable speed motor, it rarely needs to run at full capacity, which keeps noise levels significantly lower than traditional forced-air systems.
