Causes behind the problem

Temperature differences from room to room can be due to a variety of factors, including inadequate insulation, worn-out seals around windows and doors, leaks in your duct system, or a problem with your heating system.

How to turn up the heat on Cold

Professional comfort-system inspection

Your local Lennox dealer can conduct a thorough cleaning and inspection of your forced-air comfort system to make sure it’s running properly. They will also plug any leaks in your duct system.

Advanced heating systems

Lennox offers a variety of heating systems that work to minimize up-and-down temperature changes, making Cold feel not so cool anymore. An innovative example is the SLP98V variable capacity furnace, which varies heat and airflow in increments as small as 1% to provide precise comfort throughout your home.
